Re: Screen Paint Recommendation for Epson 8350

Mandalore, I made a mistake when I suggested you use a RGB 255 image for 100 IRE. Turns out the RGB value should have been 235 to equal 100 IRE. RGB 255 would be 109 IRE. Sorry about that.

Re: Screen Paint Recommendation for Epson 8350

I have redone my tests using 235 white for the test image rather than 255.

To to recap everthing in on post for clarity.

I created a test .png image 1920X1080(1080p) with the rgb value 235 235 235 and opened it with my blueray player. Light levels were tested with a lx1010b luxmeter with the sensor rested flat on the wall. I figured while i was at it i would test 3 modes Dynamic, Living room, and Cinema on my Epson 8350 projector.

The projector is 16' 7" away from the wall it is projecting on. The diagonal on the picture is approx 125"(horzontal width is 108")

The room has the option of being totally light controlled but I like having a little ambient light for anything other than a "serious movie night"

Dynamic

Top Left = 262 Lux
Top Center = 359 Lux
Top Right = 263 Lux
Bottom Left = 220 Lux
Bottom Center = 348 Lux
Bottom Right = 248 Lux
Dead Center 370 Lux

Living Room

Top Left = 247 Lux
Top Center = 334 Lux
Top Right = 250 Lux
Bottom Left = 211 Lux
Bottom Center = 328 Lux
Bottom Right = 232 Lux
Dead Center 354 Lux

Cinema

Top Left = 78 Lux
Top Center = 107 Lux
Top Right = 78 Lux
Bottom Left = 68 Lux
Bottom Center = 106 Lux
Bottom Right = 80 Lux
Dead Center 112 Lux


thanks again for everyones help.

Re: Screen Paint Recommendation for Epson 8350

So I am guessing that the new readings which are lower than my first ones with rgb background of 255 rather than 235 are not significant enough to change the original recommendations?

So my options suggested so far now are:
  • Snowfield (using valspar paint) N9
  • Cream&Sugar (using valspar paint + Liquitex BASICS 'Silver' acrylic paint) N9.2
  • White Opulence 879 (Benjamin Moore) N9.6

I was looking at the "list of know finishes and tints" sticky in this forum and did not see Benjamin Moore paints on the list. Does that mean they need more testing?

Benjamin moore is litterally right now the street for me, however I would prefer to take the safe route if there is any doubts.

thanks

Your Cinema mode brightness is now ~10.5 fL. I personally could still happily use a N9 screen, but we are now in a VERY subjective area of image brightness. A very important question now is how many hours do you have on the PJ lamp? Another important question is would you be happy using Living Room mode to watch movies?

Benjamin Moore makes good paint, but we don't have a lot of experience with it. According to the EasyRGB database they have a color called '2133-70 TUNDRA' that is a nice N9 shade of gray. If you want to use that paint I would suggest getting it in Flat or Matte finish just to be safe.

Re: Screen Paint Recommendation for Epson 8350

The projector is new actually but it has been in the box till recently. I bought it a year ago but my weekend project went a little over schedule ;-)

There is about 15 hours on the bulb.

Do you think there is something wrong with the projector or my setup?

Re: Screen Paint Recommendation for Epson 8350

Sorry forgot to comment on the living room mode.

When i first set it up i only liked dynamic mode but after watching for a bit i now also like living room mode.

Cinema mode looks ok with 100% blackout
