How do I determine the video optimized lumens of my projector a Sharpvision XV-9000U?
The proper way to do this is to calibrate your PJ; a calibration DVD will work to a degree, but you really need a colorimeter and calibration software to do the job. If you opt to use a DVD alone you will still need a light meter to read the image brightness after you've calibrated your PJ. These are quite inexpensive (around $25 at Amazon). These inexpensive light meters, for the purpose of reading screen lumens, are WAY better than meters designed for photographic use costing hundreds of dollars!

What I'm trying to do is determine type of painted screen to use. Living room that is 15' X 18' with 15'+ vaulted ceiling. The screen wall on the 15" opens into dining room that has window another 12' feet away. Windows on the other 18' wall. I can mount the projector (wall mount) as close to screen as needed (8.5' high). Seating is 12' to 16' feet from screen. Thinking 16:9 100" diag screen.

Right now I'm leaning towards Universal Grey in eggshell finish.
Any recommendations?
The Universal Gray in eggshell finish using Valspar Ultra Premium interior latex would be a good choice, but I would recommend a smaller screen size since your PJ is a bit lacking in lumens. A 100" screen would only give you 13 fc of image brightness with the PJ mounted at 13' 1" from the screen. This is a bit dim for many people and will only get dimmer as the lamp ages. Dropping down to a 93" screen and mounting the PJ at 12' 2" ups the brightness to 16 fc which most people find OK. I'm using the data from the calculator at projectorcentral.

The reason why I specified the Valspar paint above is that not all paint brands use the same gloss levels in their paints. One brand's satin me be another brand's eggshell, or the opposite.

Re: Official Screen Recommendation List

Just looking through some old posts, Sherwin Williams SW7071 Grey Screen is a close N8 solution.

Another post lists SW6260 Unique Grey as another N8 solution.



I'd love to see the thread updated with other choices

Re: Official Screen Recommendation List

It's been a while since anything was added to this list. Have there been any new DIY screens that anyone would recommend?

White Screens

For this and the next several posts the layout will be known screens that match the thread title. All options mentioned will be screen methods (both commercial and DIY) that perform exceptionally well. There is no particular order or preference of one being better than another. It is a compilation of known screens. For more information on a particular screen, refer to the appropriate thread for that screen option.

White Screens
White- what exactly is white? Technically it's a color value of 255 255 255. Black is 0 0 0. Anything in-between is technically gray. The thing is at a certain level we see and perceive these very light grays as white. Our brain is a complex but funny thing. We look at our surroundings and certain things we 'know' are supposed to be a certain color, so that's how we see it. Nobody has pure white walls, even as white as the trim looks, as stated it technically isn't a true pure white.

So does all of that really matter? Not really. Just that we understand a few things and why so many whites can look so different from each other.

White screens are some of the most basic and easiest. They are also the most forgiving when it comes to calibrating a projector. For dedicated rooms with total light control, white screens will produce the most accurate color reproduction as well as the best and most stellar whites.

Sounds perfect right? Well sadly no screen is perfect, nor is there any screen that is a one screen suits all. White screens take the biggest hit when it comes to ambient light viewing, and depending on the projector, they can even be too bright. 12 fL (foot Lambert's) of brightness is considered ideal for total lights out viewings. I've observed that you can go to 14fL and still have a vibrant image without whites and bright colors that bloom, but higher than that and eye fatigue can set in, even headaches.

Another issue is if the room isn't a dedicated theater room, meaning darker colored walls and ceilings, a bright white screen can actually produce it's own ambient light problems. The light from the screen can and will bounce off the white walls and ceiling and back onto the screen. As I mentioned, white screens tend to wash out quickly and for some people this rebounding light is enough that some people prefer another option. However if they are willing to make a few adjustments to the room, they can correct any scatter light issues that may be a nuisance to them.

Without further ado... the know white screens.
