I just had the opportunity to get 2 units from this same monitor, same manufacturing year from yours! Both are in bad cosmetic shape but with great image quality. I'll repaint both, just need to discover what is the color name, both the metal cover and the front plastic bezel. Later, some recap and calibration. Thanks for all your videos and information! Cheers from Brazil!
Hey retro tech, what are the reasons you'd want a pvm over a consumer CRT besides RGB inputs from the factory? Just curious like are their displays better? (I know they can do higher res. If they are high end and there are some wide-screens, really wanted to know why they are better
Most PVMs don't do higher input signal res than a consumer TV. They do 15 KHz; in other words 480i and 240p (plus most PVMs support PAL's 50Hz 576i and 288p equivalents). So apart from PAL support there is no improvement in input res capabilities. The major difference compared to a consumer TV is the overall precision of the screen (that being said some consumer TVs can be really good too). Convergence and geometry are (potentially) great and consumer TVs have more coarse masks, leading to a TV Line count of rarely more than 450 (this is a measurement of horizontal resolution by the way [even though it's called lines] and it's not to be compared with pixels as CRTs don't have pixels). Also most consumer TVs use the shadow mask which apparently does not show scanlines in 240p as pronounced as a Trinitron and people love scanlines.
The simple answer is a higher phosphor-count, which means more vertical picture detail (NOT horizontal picture detail. Horizontal picture detail is 240p/480i/480p/1080i/720p/1080p/1440p/2160p/4320p). A television set from the 1980's, rarely had a line-count over 380. The 1990's, 500. The line-count of a C.R.T. tube is calculated from a 1:1/3:3 aspect ratio. ...but C.R.T. tubes have a 4:3 aspect ratio... ...to estimate the ACTUAL vertical resolution of a C.R.T., we add 25%, to the line-count. 250lc=313 lines, 450lc=513 lines, 600lc=750 lines 800lc=1000 lines 900lc=1125 lines 1000lc=1250 lines 240p consoles have a maximum vertical resolution of 340 lines. ...the 250-600 line-count monitors are fine for that. A 480i/p console has vertical resolution of 680 lines. A 450lc monitor and above, is fine for that. A DVD has a maximum vertical resolution of 720 lines. A 600lc monitor is fine for that. A 720p console has a vertical resolution of 1280 lines, an 800lc monitor is fine for that. ...and yes, you CAN connect an HDMI cable to 3G SDi, to connect an HD C.R.T. BVM. A 250 line-count monitor looks like a crisp LCD screen. An example of this, is shown in this video. ua-cam.com/video/brdg6ToAt78/v-deo.html If you did not grow up with scanlines, then these might make out for acceptable desktop retro gaming monitors. A 450 line-count monitor, WILL have distinguishable scanlines for 240p content, and very thin scanlines for 480i content. I use a 1340 PVM from 1991. Its "high contrast" screen, slightly retains an image for each interlaced frame, which means that the odd lines have a visible image, at the same time as the even lines. This means that 480i looks VERY similar to 480p. The 480i image barely "jumps", like my childhood JVC C.R.T. People say that a 600 line-count monitor is good for 240p gaming. The scanlines are even thickness, compared to nonscanlines. 800-1000 line-count monitors, are good for 480p/maybe 1080i/720p content/gaming. Their 240p scanlines are supposedly so thick, as to darken the display to an uncomfortable level, without a gamma boost. Excessive gamma boost, shortens the usable life of a C.R.T. 480i content supposedly jutters (horribly), because the scanlines are so spaced out. Depending on how critical the on-screen detail is to you, you may or may not want to play 1080i footage on these monitors, because they have a maximum vertical resolution of 1250 lines, and a 1080i image, has 1920 lines of vertical resolution. You will lose image crispness, if you do not use 480p or 720p. It should be noted that 250-450 line-count monitors are 8". 450-800 line-count monitors are 13-17" (JVC made 17"ers) and 20-36"ers are 450-1000 line-count (the 450 line-count monitors from this size category are from the 1980's and the 1000 line-count are from 1999-2007). ...why am I saying this? A VERY high end television set from the 1980's, would have ONLY had a 450 line-count, at 25". 1990's, 600lc @ 25". ...a PVM/BVM with 450-800 lines at 14", is SUPER crisp. This video shows what a 1990's 13-19" tv set looks like, RGBs modded. ua-cam.com/video/NkpSBK3g-gA/v-deo.html The modder says that its image reminds him of a mid-1980's RGBs computer monitor. This video compares an RGBs modded consumer C.R.T. picture vs. an RGBs PVM/BVM C.R.T. picture. ua-cam.com/video/jbi9HEz-cww/v-deo.html This video also has good comparison shots, and a fairly good explanation of consumer-grade C.R.T. phosphors vs. professional-grade C.R.T. phosphors. ua-cam.com/video/RAi8AVj9GV8/v-deo.html If you are interested in playing 1080p games or movies on a C.R.T., buy an HD Fury, so that you can laglessly run tun a signal through an HDMI cable to a VGA output. This allows you to play a game from a high definition source, to a high definition computer C.R.T monitor. Depending on the C.R.T. computer monitor's specs, you can game at 120Hz/480p, ua-cam.com/video/ZHphWoLEVFU/v-deo.html Or 1440p, at 100 Hz. ua-cam.com/video/HrhsWnEMafA/v-deo.html This is good review of the same topic. ua-cam.com/video/BmtmWk3puGg/v-deo.html 1440p in a 4:3 aspect ratio, will lead to 1080p, when viewing 16:9 games/Blu-rays, on a 1440p 4:3 C.R.T. monitor. Most 1440p computer C.R.T. monitors support 12-bit color, so enjoy watching HDR movies on it. I hope this information is helpful to you.
@@badreality2 I have to disagree about the terminology. Common terminology says horizontal is from side to side and vertical is from top to bottom (or bottom to top). And due to that what I said is true. For example, 240p is not the horizontal res - it's the vertical res: it's the number of lines or rows, starting to count at the top line until the last line at the bottom; in contrast to columns or pillars from side to side. Since the lines in an analog signal are discrete, a CRT doesn't even have any other choice but to display the lines count (such as 240p or 480i) of the input signal, minus some overscan and possibly somewhat compromised by bad convergence or focus. The TV Lines measurement is a measurement of the horizontal resolution capability of the mask/phosphor combination (details per line, count from side to side, number of columns/pillars it can resolve). Heck, a Trinitron mask doesn't even have any vertical grid (unlike shadow masks), therefore the vertical res (top to bottom) is virtually infinite and only limited by the beam and input signal.
could you recommend me the Capacitor Kits you use for the Boards in this video?, a friend just gave me a Sony PVM-14M4U, and it has some issue including the RGB lines of death, but it does power on and it does show a picture but i would like to do whatever i can to try and revive it. thank you for the videos they have been very informative and luckily you have a couple videos on these M series PVM
I've yet to start that restoration. It's been too hot this year, but It's still in good shape and my daughter loves to play on it the most. She's four years old and her favorite game is Fatal Fury 3. It's so funny.
So could the caps on the power supply cause some ripples or wobbles in the screen geometry too? Like mine still has some issues with that, might have someone able to re-cap the whole power supply for me though. He already did a few caps where he thought some problems may have been but it didn't fix the issue. Also, do you have a video for the usual caps on the geometry A board you recommend changing? Maybe I'll try and get all those done too if you can detail which. Thanks!
Retro Tech Hey I didn’t get notified that you replied, sent an email recently seeing if you could maybe help trouble shoot a problem I’ve been having with geometry. Just want to drop a line in case went to spam. Email slightly outdated, had the power supply re-capped but didn’t change the issue. I can provide some pics and video if you can help me work out the issue. Be much appreciated Thanks
Do you think PVMs will just keep going up in price as eBay sellers slowly destroy the remaining supply with bad shipping processes? I've been trying to keep an eye on any with local pickup options within 100 miles but no luck.
Lol, if you think that's bad, you should see how people in Japan package stuff. A 20" PVM? Sure a layer of bubble wrap is enough! Well not my fault if the shipping company is being rough with it! The only reason stuff arrives whole in this country is because shipping companies here are extremely careful compared to other countries' shipping companies. Sadly people here do not realize just how careful they are compared to other countries.

Do you think PVMs will just keep going up in price as eBay sellers slowly destroy the remaining supply with bad shipping processes? I've been trying to keep an eye on any with local pickup options within 100 miles but no luck.
yes
Is the PVM 14M4U 480p compatible? I have a chance to buy this model.
Nope, you will need an PVM L5 for that.
Would you consider this to be a top 5 in pvms for retro gaming?
I wouldn't say that styro is any softer than equivalently thick layers of cardboard.
Lol, if you think that's bad, you should see how people in Japan package stuff.
