Awesome info man, I think you are the only one sharing this at youtube. :) thanks. Question , hoq I can mesure the gain of my proyection screen? Wich device I will need?
Brilliant explanation thanks. I have an Epson EH-TW5650 projector and a 1:1 grain screen and have a bright spot which moves depending where you sit. It looks like a reflection from the lamp. Have tried fiddling with the settings, but no luck, any advice?
they will probably say that the projector is too close to the screen. It needs to be at least 1.5 times the width of the screen, etc. You gave no details as to your setup.
Hi, very interesting your body, even with sunglasses :). I have a question, nowadays I'm protecting in a wall with a painting white ultra mate with 1.0 gain. My projector is the eh tw7400 epson 2400 lumens 4k (shifting) hdr. My room is a basement totally dark, but my distance of projection is 5,5 meters (216 inches) and the size of the area where I'm projecting is 165 inches (16:9), what makes lose a lot of light. In fact, I'm getting, measuring light with xRite, only 65 nits (around 19 ft). Do you think i would win quality and light but don't lose to much contrast with a 1.4 gain screen? I'm thinking in buying one but its a high cost and i would need recommendation before buying it. Thanks in advance.
@@hometheatertv i found a brand that offers me a 1.8 gain screen? Too much gain in terms view angle and maybe possible hot spot? Right now Im getting 65 nits (19fl) then 1,8 would give around 120 nits, what do you think? Thanks!
+Peter Wood not understanding question, 1.3 gain will make your 1000 lums more like 1300 lums if that's what you mean, it's not an exact science but that's the idea
@@cwize it does, but at the cost of a smaller viewing cone, and most screens have a cone angle number given, but that is when it is at 50% lower than center. I am fighting screen samples that look great in the middle but are dark on the sides, even 30degrees from center.
thank you so much for the info!
Love how the way your presentation...

if you can get a bit more screen gain that would be better that 1.0 in your room

@@LuisPeris Maybe to much give up on viewing angle, I would keep it 1.3 to 1.5
"oh that smells good" 🤣🤣
so is a 1.3 gain screen an overunity device?! 1000 lumens out, 1300 back...

so wrong. LOL
