*stares at my dead pixel in shame while watching*
+Orange Peel i have 34 of these
WutFace
+Orange Peel I have 2 stuck pixels on my VG248Q :(
My iPad I've had for 2 months has a dead pixel
+Poketrevor if you bought it new there should be warranty on it. Take it to Apple and see what's up
One of my dead pixels got back from the dead
I'll name it jesus
lol
lol
+Eliott “ReDeathRay” Castafolte
oh wow...
xD
Hahaha I'd give you a like but I'm on mobile.
I'm glad u didnt troll people by making a stuck pixel on your video!
I already have a dead one :(
this had been funny
but he actually is pretending backlight bleeding
i think they tried but didn't work because of different video quality or resolution
OBVIOUSLY YOU HAVENT LOOKED AT A MONITOR FROM THIS ANGLE
"screen saver" now i know why it's named "saver" FINALLY
Exactly
+tulp35000 I've thought the name was stupid.. Turns out I was being stupid... The more you know :P
+tulp35000 Funny how I never made that connection. You learn something new everyday eh?
+tulp35000 Yup. The name goes all the way back to when all we had were lowly CRTs. Those really get burn-in *fast* because of their dependence on phosphors. (Though CRTs are still used for certain specialized applications.)
+tulp35000 ohh wjy always when i have a good comment the idea has been used :(
my 4k monitor has 1 dead pixel. it's barely noticeable but i think i should return it because now 1 out of my 8 million pixles dont work shmph
Return it it's useless now. Completely ruined...
2159p. I feel bad.
+DragoonDark97 XD hahahahahah
+DragoonDark97 lol
+Twiist Took me a week to notice a dead pixel on mine. I thought it was a speck of dust at first.
I remember 10-15 years ago I had my first non CRT display. It died promptly to an airsoft pistol shot :(
+Weese Was it a plasma?
+Weese I feel your pain brother... moment of silence for all of the fallen displays we have lost to stray bbs.
I guess it isn't really a problem with crt monitors...
+Allen McFine Nope. Used to display a picture of a target to shoot at.
Weese is that how you broke your flatscreen? :P
THATS WHY ITS CALLED A SCREEN SAVER!!! :D my life is complete
+Scavapixel It was especially important to use screensavers on old monochrome and CRT displays. Now, there isn't much need, but if you leave you monitor on a lot, it's still a good idea because burn-in is still a thing.
THERAZORKILLE OLEDs are sensitive to burn in
Exactly!
I always wondered why they were called that
This comment aged me 10000 years
i have backlight bleeding but i can literally only see it when the entire screen is black
nice
Imran Haque acer gn246hl
Imran Haque yeah lmao
LCD's always have backlight bleed because pixels can't become fully blocking.
strange i have blacklight bleeding on my old lcd but only on left side and its pretty small
I have backlight bleed on my phone
Could you do a video on calibration? Not just with high end tools but for a mortal person as well.
You can't do that
use lagom website to calibrate your lcd yourself
Ohhh, I just realized what screensavers were for! I GET IT NOW!
+TrivisionZero LOL
i allready knew! haha
I just found out also
Silica well good for you smarty pants here's a fucking gold star.
wow.. for 20 years I didnt know the purpose of a screen saver
A few years ago I bought a new monitor ans it had no dead pixels. A month later, a lot o dead pixels suddenly appeared. Each time I turned on the monitor, the dead pixels were in a different place! I looked with a magnifier and each dead pixel was actually the shadow of a baby spider. After a couple of weeks, all the spiders disappeared: nothing to eat but each-other. They must have all fallen to the bottom of the case.
Only -- two years later a faint smudge showed up. Over a couple of days the smudge got sharper. A dead spider had fallen against the back of the LCD panel (the thread holding it away must have dried and finally broken). So, now I have one dead pixel that doesn't move. I could probably open the monitor an clean all the spiders out -- or I might do more harm than good. Someday I'll replace the monitor and then try to clean it.
If there's a contest for the most unusual monitor defect, do I win?
Yes.
have you tried turning it on and off?
+Ivan Alexander How would that help dislodge a dead spider? But, yes, the defect has been there more than a year and the monitor is switched off every night. Before the spider stuck in its present position, you could cause it to wobble a bit by shaking the monitor (I was trying to get it to swing back away from the LCD panel).
+Ivan Alexander lol
looks like your monitor had a few BUGS
Linus, I can't thank you and your team ENOUGH for these videos. They are so informative and can really be a lifesaver or moneysaver at the very least.
mine looks all blurry, then when I clean my glasses it looks good again... what do I do?
maybe stop trolling?
I don't think that my comment would be considered trolling, more like stupid. But either way I should just stop.
+Caleb Hiebert people like you keep.the comment section somewhat funny ;)
i recommend pouring milk int the vents and ports.
r/woooosh
My older screen had porn burned on it, I sold it on ebay and got a new one.
OMFG that sounds like me
Gandalf Greyhame As long as it took some dude to pay 120$ for it. It wasn't very clear image though.
Farmyard porn, girl and horse stuff I bet.
Why would you have the same porn video paused on your screen long enough to be burned on?
@@roshanpaul1184 video was so good you could whack it for hours
Burn in can actually happen with flashing too. Found that out myself. Went to a site that had an error that caused the screen to flash repeatedly in the top. When i went to my desktop, the top part started flashing as well. It fixed itself after about 30 minutes
I'm adding: IPS ghosting, can happen on some models (afair, technology matters here).
I experienced it when my video driver got 'updated' to a non-manufacturer version - which didnt have the anti-ghosting algorithm.
took me a while to figure out what happened.
Interesting fact: I've had a stuck pixel that would only appear if the rest of the screen was bright and the area it was on was dark. It wasnt really a problem unless you looked at a big bright window in a game and then that super bright red pixel would appear, but if you made the entire screen black, the pixel would darken so you couldn't see it (or properly test for it)
my "Exotic Pictures" got burnt in to my monitor
+Shanee Bahera now you can save money on electricity while watching them
+Siddharth Nair best reply
Were you watching tiger porn again?
Now where's my Monitor Hammer™? 🔨
Wanted to press the like button, but that count is too perfect for this comment
So that's why it's called a screensaver!
"don't stare at the monitor too long, your eyes will go bad"
"no mom they go ultrawide"
... so i guess i shouldn't shoot my fucking monitor
naw I do it all the time increases the refreash rate by 1000000000000000000000000000%

He died as he lived, on Linus' forehead.
It’s incredible how a single dead pixel can annoy the crap out of you if you focus on it. Once you get used to it, you never think about it again. Ignorance is bliss!
Yeah, I also have a stuck pixel and when I stare at it it's really annoying. I noticed the stuck pixel only after about a week of use of my new monitor.
I found a UA-cam defect.
1. Full screen this vid
2. Type "awesome"
3. Enjoy!
Must be on PC!
now try to fix stuck Pixels with that :)
Dude you are my hero, thats a nice easter egg
Copied
So that's why it is called screensaver... :o
+Khotta Bogard But then wouldn't the screensaver burn in instead?
+Theo “Theodoooore” higgins Burn-in happens when a certain area of the screen never changes, as in when you display a static image on your display or on any part of your display (like the task bar on a computer, for instance). A screensavers moves all over the whole screen, refreshing each pixel enough times so nothing lingers long enough to burn into the screen
+Pandsu Yo Indeed, that's why all screensavers are animated and why the DVD logo that shows up when a DVD player isn't playing anyhting moves and bounces across the screen.
Many modern TVs also let notifications like 'no signal' move up and down slowly to avoid them burning in.
... good lord wtf did you think it meant?
i flashed a different rom on a s3 mini and the old icons are still burnt into the panel😂
Lol
+Tim Brandt Corstius rip
+Tim Brandt Corstius My s3 mini had the boot screen burnt into it,cause it failed to reboot when i was asleep once
+sanjay900 my htc one m8 has the navi button burned in... i had a mod to make the bar transparent and so only the buttons are burned in....i found out because i started playing a game that makes you hold it on its side
sanjay900 wow thats really a fast burn in
You totally left out the most common issue I'm encountering these days: brighter spots which are only visible on bright background; supposedly caused by particles or smudge on the light diffusion layer.
Is there a fix to that? I think I have this issue 😒
Well my $450 34" 21:9 LG display had backlight bleed from the factory. Yay.
Clouded displays are common on smartphones. Makes sense, because they are constantly being thrown around.
My friend left cooky clicker going for 2 weeks on his S4. The cooky is now burned into the screen lol. XD
+HiiighAsAKite if the display is an lcd the burn in is called image persistence and in all but the worst case is completely reversible. The general rule of thumb is in order to get rid of it you need to cycle though a lot of colors fast for the length of time that the static image was displayed thus while it may be reversible depending on how long the image was displayed it might take a LONG time to reverse. you might also try truing the display off for a while as sometimes that can lessen the severity of the image persistence. oh wait you said s4 that puppy is oled in witch case the burn is permanent.
+Trekeyus old AMOLED panels problem.
Ibraheem Al hadede
my bad AMOLED not OLED
As I learned the hard way, incandescent light bulbs that are too close to your monitor can also severely burn in your screen. so replace your desk lamp with a CFL or better yet a LED bulb to minimize the damaging effects of light bulbs on Monitors.
I got a monitor off craigslist for $20 with a nice desk, it's a great quality QHD monitor that would have been sold for a lot more, but there was an entire row of pixels that was black, as if it was completely dead. About a week of heavy use after i got it, the line went away and it hasn't manifested itself again in anyway even after short term garage storage!

+Razor2048 I would only modify your idea with Apollo computers as fast as possible, hubble computer as fast as possible ,etc... like the idea though
That screen with a burned-in "please wait" depresses me. Oh loading times, why art thou?
there’s a conjecture that said to multiply numbers is o(n^2)
When I was younger, my parents had a nice 17" 1152×768 WXGA CRT monitor. I didn't really know exactly how CRTs worked and found it fascinating one day that dragging a kitchen magnet would change the colors of the monitor to rainbows and back. Problem is, it created a kind of permanent "burn-in" where I drug it along. We got rid of the monitor in 2017 when we got a new computer (It was just over 10 years old). I still miss that monitor however. Since it could display at up to 120Hz, if I had the chance, I'd have used it as a high-refresh rate gaming monitor as a short-term solution until I could afford an 1080p or 1440p gaming monitor. 😆
I don’t even watch your videos. I just love hearing your technical voice
I used to play Forza 3 ALOT when i was young and my huge tv had a burned in RPM Gauge and 888 from the digital display in the bottom right XD
A LOT* :)
i have burn in on my galaxy s7 edge
and your alive?
It was the Galaxy Note that exploded, not the S7 Edge
more than just the note exploded of recent from samsung lol thats why i said it
+menderus No it wasn't. Only the Note 7 had that issue.
ehh check your facts
Oml, the example at 1:20 actually fixed a stuck pixel. That's why I came here. Thanks Linuuuuus, And Lucas, And the guy who put in the thing at that exact spot
I literally did not make the connection until now that a "Screen Saver" is literally for avoiding burn in. I just always thought it was in necessary or for looks when you walked away lol. Plus I am also staring at like 15 stuck pixels on my 2012 15" Retina MacBook Pro
My uncle's old tv had about ten different channel logos and loads of channel numbers burned into it. At least that's what it looked like. You could see ghost images of moving faces from other channels slide over the screen, which must have come from something else. Not sure how he screwed up his tv this bad.
Great video. Sadly even the best of the best IPS monitors like Asus Rog Swift PG279Q have backlight bleeding. Had to change 3 times to get one that was acceptable and still not perfect. Got another one yesterday (almost 2 years after my first) and i thought it was perfect but no, on the top right there is bleeding. I dont think i will get a better one sadly. Seems all IPS monitors have this issue to a degree. Sad true!
🎯 Key Takeaways for quick navigation:
00:00: When *setting up a new monitor, it's essential to check for any defects.*
00:41: One *common defect to look for is dead or stuck pixels, which can often be fixed or replaced if the monitor is under warranty.*
01:52: Backlight *bleeding can cause uneven brightness around the edges of the screen, and it's best to avoid it by investing in a higher-quality display.*
03:12: IPS *glow is a different issue and can be reduced by adjusting your viewing angle, while clouding is usually a result of physical damage to the screen.*
04:22: Burn-in *can happen if you display the same static image for a long time, so it's advisable to use a screensaver or turn off the monitor when not in use.*
05:15: Taking *proper care of your monitor, doing research before buying, and handling it with care can help avoid most monitor problems.*

Anybody know how to fix ghosting?
It happend when i turned on overdrive on my monitor. I disabled it now, but there is still ghosting.

LCD Light Bleed vs OLED Burn In
When going with the higher cost professional monitors that are used for calibrated photo and video editing, there is much less chance to have defects. The high end monitors are using higher precision parts, and assembly standards along with more strict calibration.
Typically, the low cost consumer monitors will not be absolutely perfect. Out of the box the low to average cost monitors may not all look exactly the same, and may each have some small defects.
With LCD monitors never touch the screen with the fingers. A small amount of any pressure can do permanent damage to the screen. Never leave the same image on the screen for many hours on end. LCD monitors can suffer from what is called stiction. This is where the LCD crystals can accumulate ion charge. Ions are much heavier than electrons, and will take longer to dissipate. Remember the liquid crystal works at near to the molecular level. The electronic components used in the substrate layers that drive the liquid crystal polarization are sized down to nano levels, in the size range of less than 32 microns. Much smaller than this size range when down to less than 1 micron in size entropy, some influence from quantum laws, and other complex factors can take place.

Linus accurately predicts my purchase of the Odyssey G9
My monitor sometimes gets this are very faint high-pitched buzz behind it when playing counterstrike. It's not all the time but when it does happen, it happens all the while looking at certain objects in the game. The noise sounds like a balloon slowly deflating between somebody's thumbs
I wish I could hear it in person lol
Probably coil whine, Google it. I've actually had GPU's that had terrible coil whine.
Someone please get Linus a Sham-WOW so he can do the skit already!
5 years later and this video is still so helpful! Thank you.
3:49 Thank you; my iMac was found in a dumpster, clouding would be inevitable.
My old phone had burn in screen ... and after a night of screen on i can still read what he was displaying lol
What about pressure marks? Unlikely to be defects, but still worth mentioning imho.
Great video! Oh and with all the "do the thing" in the last minute of the video you reminded me of Varrick from legend of Korra.
every 20 frams linus will make a funny face.

Lynda.com? Is that the site that claimed they will destroy ISIS?
This was actually a very informative and thorough AFAP. Thanks.
I love you Linus, the eraser trick just fixed three pixels on an old monitor.
when I was a little child Minecraft HUD was burned into my tv
Minecraft isn't that old, so you must still be a kid.
Yeah thats why i said little child im 15 lol dolebiscuit
You a baby!
lmao.
ooooooh so that is why screensavers exist :D
now I get why it is called a screen saver :) to prevent burn-in
backlight bleed is mainly due to how the backlight is made : LED light cells are distributed on the edge of a translucid piece of plexiglass, shining in its thickness, the light is diffused through the main face but brighter on the edge.
Firmware as fast as possible
Yeah I bought "aoc cq32g1" several weeks ago and almost everything seemed to be fine. Except for blacklight glow that isn't an big issue. But the worst is ghosting of it, man it's terrible with that. It's playable, but I still have that in mind that while moving camera in game I can't see a beautiful 144Hz and I could just buy more expensive monitor with blur reduction technology.
I saw documentation that Aoc have blur reduction but it's available if you have freesync OFF, but still doesn't repair the ghosting, it's the same ghosting no matter how I set it, so what's the point of that option? It have overdrive option which on OFF, low and medium it looks the same :/, on high setting it's better but then I got weird colors when I move, I will name it color artifacts.
But I don't know if it's fine or no, most of the time I play in night so I should use VA monitors, but they have the strongest Ghosting I think, IPS suffer with that too. TN have the smallest ghosting of them all but black color and contrast it poor there so I could not be satisfied with that either.
It's been 3 years since you've put that comment up. The monitor is likely "fine," so to speak, but I'm sure it was a budget monitor, which often suffer from that. What you are describing is a bad "pixel response time." That's the time it takes for a pixel to switch from one color to another. A slow response rate will cause ghosting, whereas a fast one won't.
My laptop's screen had dead pixels that occurred from sitting an expensive monitor on it, but then they disappeared a few days after the monitor was removed.
linus idk if u cud hear me i remember u going back at least 12 years. good to see u are still at it
Funnily enough, I found a dead pixel during this video.
OMG is that why screen savers exist?!
Wait are you being serious
My old iPhone 6s had some issue with the backlight, it had one point in the upper middle of the screen that was always far brighter than the rest of the display, and it was particularly noticeable on bright images rather than darker ones. I’ve never known where it came from.
Backlight bleeding really isn't that bad if you're just doing office applications and web surfing... one of my old LCDs has it, but I still enjoy reading text on it better than my others. I'd never really want to do any kind of color-sensitive work on it, though, LOL.
We went from "weird growth on my chin" to one of the most majestic beards in TechTips history. That's character development right there. Or maybe just puberty idk
great video as usual. Now, I have a question about your production habits.
Why... after so much time doing these videos are you still doing (guessing pushing a button) something behind your back or in some cases under the table your recording around? Your the only content creator that I sub to that does this annoying action. Trust I'll still watch your great content no problems there. But, this is more or less a bugging pet peeve that I have with your videos. It makes me pay attention to what your doing under the table or behind your back pocket instead of the actual reason for watching. IMHO it would be better to just gold the remote/clicker/object in your hand and just do whatever it is that your having to do without seeming like your hiding something.... lol. No offense, just words for thought.
0:30 Linus, you think I can't see your daemon tools on that desktop, you pirate!
I'm terrified of buying a monitor and having dead pixels and they're not covered by warranty.
Others: *Gets new display monitor*
Meanwhile me: *Talks dirty to my pc dead pixels to turn them on*
(ノ ͡❛ ͜ʖ ͡❛)ノ
You sad emo nerd lol
Came here after I broke my monitor :-(
A screen I'm using at work has a 'defect' that looks like backlight bleeding (the edges and corners are much brighter than areas in the center) when it is just turned on, but it fades away after it's on for a few minutes. What is the cause of that 'defect'?
This video only goes up to 1080P, and you also forgot about high refresh rate monitors....
Hey Linus, you're face is aliasing. Might want to see a doctor.
4:19 anyone else from Israel?
I recognised that place when I went to Palestine!
yes Israeli McDonalds wow!!!
For a while (back when I watched cable TV) I use to get this weird cluster of white pixels in one of the corners but only on 1 or 2 channels. the rest were fine and using my TV for other things seems to be perfectly fine too.
There was also an older flat screen PC monitor that had a single green pixel effect in one of the upper corners that would only show up when I had transparency turned on... I think that's how it worked.
Both my TV and current monitor are working fine now though.
My old toshiba has dead pixels. A website is hwlping and most are barely lighting up now whereas before they were solid black
the burn in reminds me of this old CCTV CRT monitor that was in the tv production room. it was so bad, i actually thought the monitor was on and i was watching the actual camera feed. until i found the plug which was unplugged and the teacher had laughed and informed me that it was burned in
i once saw an S7 in display with the burn-in problem, it's pretty terrifying in person
I poked my stuck pixel with a pencil and it multiplied.
what should i do if a ant crawled in my screen and died? lol
0:56 Epileptics will love this.
I watched this video with a dead pixel right next to Linus
Happy Easter Linus!!!
The outro was freaking amazing.

I'm waay too scared to go checking my brand spanking new $600 display for defects. I just want to assume it's always perfect damnit!!
Yea i would bot a 700$ips 165hz ...but i am thinking i will just end up returning it over and over until Im an old man cleanging for the hope that i will get one without any issues.
Thanks chief I was gonna replace my laptop but it’s just iPS glow
I have a big dark patch in the bottom left corner of my monitor. None of the pixels are dead, but they're much darker then the pixels around them.
I just bough a 4k screen (LG 27UD68) last week and this information was very useful indeed. :)
Everybody gangster until they see lines.😳
The only defect my TV has is a scratch on the screen. I accidentally scratched it with a scissor
Black light bleed, is really common and it doesn't really effect anything (in my opinion)
Why it forms due to load on screen or what pls reply
