I was ready to go out and get a can of SW Grey Screen or TV Winter Mist, but now I'm wondering if this thread is outdated and better things have been found than these neutral OTS solutions, or if wbasset and others ended up continuing their research in another thread that I should pick up on in order to find the ultimate conclusions they've come to. If so, any recommended threads for me to start on? I'd like to know what conclusions have been drawn at this point...

It sounded like wbassett had tried laminates, but found these neutral grey paints to be better. Any difinitive word on laminate's vs. paints?

I know much depends on my setup. I have a Epson 8500UB, long throw of 22', low but still there ambient light, and like my image big, like 176" diagonal at 2.35:1 (willing to go smaller, if laminate turns out the best route for example, given standard sheet size).

Thanks again for all you guys' research, time, and effort.

Joe

Sort of wondering the same thing. Happy to mix some paint if the result is much better but if an OTS gray on Sintra is gong to be very good, that would be a great option to explore. Any thoughts from the pros??

They are still working on their paints. If you do a search for black widow screen, then you should find them. They have tested and measured their formulas and come up with a variety of solutions.

SW paint

About to paint a wall screen with Sherwin Williams 6259 "SPATIAL WHITE", Duration matte. N8.75, RGB 222 221 221. Seemed like a good middle of the road choice, but not popular at all. Any thoughts?

Most do not find a Matte White suitable for varied watching conditions (ambient light...reflective room surfaces)

However if you have a dedicated Theater, one with non-reflective walls / ceiling, and a PJ with exceptional contrast, a Matte White might fully satisfy you.

Screen size, room conditions, PJ specs....all should be considered when making a screen surface decision.

If the RGB stats haven't changed drastically, it sounds like a really nice screen in any decent room. Expect around 0.7-0.75gain.

Thanks guys. It's a BenQ W1070 with about 1000 hours on it, preferably running in eco mode. In a living room but only at night, with a light on in the next room, no light control. 120" screen, ceiling mount, 11ft viewing distance. Used with HTPC, so a bit of surfing the net and video games. Watch mostly TV - OTA or downloaded.

Was just projecting on the off-white wall for a while, with a black ribbon border. Tried the Pro Classic Satin, was far to reflective for my setup, major reflective hot spots and roller marks. Hoping for slightly better blacks, and sharper picture.

The matte-N8.75 should give a similar brightness and black-depth as the off-white wall except it'll have better color-accuracy and white-balance. Going with the matte should also keep rollermarks away and give a clear crisp image. It will be dimmer than the shiny white you tried, but you should be able to stay safely over 10ftL all the way through the lamp's life in even the darkest setting.

If you went with enough of the matte-N8.75 to experiment with, you could try adding some water-based silver metallic to it (FolkArt, RalphLauren, and Rustoleum are excellent brands if you have access to them). That would help keep your brightness at the same level while helping your blacks and deeper colors stay deep against some ambient light and against wall-reflections from your light walls. You can add a ton of metallic without hotspotting, but you'll still need to be careful to avoid roller-marks if you make a mix more than 20%-25% metallic.

Silver

Thanks, think I actually have a mostly full 2oz bottle of Folk Art metallic silver already, will add a little bit in, probably in the range of 5-10%. How much color push could I expect from that and do you think it would be noticeable?

I've heard at least one person comment how they really liked the boost they got by adding 10% to a light-grey. Normally I'd expect the difference to be too small/subtle to really be noticed, but they noticed and enjoyed the difference so you'll probably fall somewhere between the range of seeing little to no difference and simply enjoying a nice matte~N9 OR you'll hopefully see and enjoy some gentle improvements to contrast that would otherwise get stunted by the white walls/ceiling.

Just remember to roll slower+gentle and try to finish every painted row in the same direction..that'll help lessen the chance of roller-marks. If you're as cheap as me, don't give into the temptation to reuse a roller-pad. When you've painted a layer and are waiting for it to dry, toss that thing and use a fresh one for the next layer. Using a fresh 1/4" roller for each layer is probably the best $1-$5 you can spend toward getting a smooth rolled-on paint finish.

Push?

Do you think there will be any color push by using that silver metallic in a neutral paint? Read other comments that it could push blue.....but with less than 10%? Thanks!

The SterlingSilver FA is pretty decent looking even at 100%, not neutral I'm sure but pleasantly close, so I believe a 10% mix should look really neutral.

Hate to necro a dead thread, but I was looking into neutral grays for doing panel boards for behind my TV sets with bias lighting.

As I was going through it, though, I got to thinking with the proliferation of LED lighting for houses, such as Panasonic Hue, among others, has anyone tried accent lighting or colored lighting of this type in their homes and how the light works with walls generally painted a neutral gray?

Also, I've seen people check the RGB values with spectros here. I was wondering if people verified secondary color accuracy as well with the neutral DIY mixes?

And finally, has anyone played with N5 and darker neutral grays considering the advances in lumen output of projectors these days?

There are no Dead Threads......only forgotten, neglected, malnourished and decrepit. ( ...a Closed Thread is different, it's in Purgatory...)

Generally, a Neutral Grey will not add any distinct Color push to reflected Light...just attenuate the intensity of such dependent upon the depth of the Grey shade.

If you mean secondary Surface Reflection values, that has been done more a subjectively reasoned approach.

Both posted examples were custom Mixes that used <N5 Base with added elements to enhance reflection without sheen'ing characteristics. Again...the only real effect on the image was an attenuation factor related to Grey hue depth.

I think @bud16415 used N5 gray to paint a wall that he uses for variable size video images. He'll be notified that his name was mentioned here and should drop by to explain his experience with a 0.5 gain neutral matte gray painted screen wall.

Projector Viewsonic Pro7827HD max screen size for IMAX 110” seating distance eyes to screen 8’. Screen stealth painted finished drywall .5 simple gray fortified with water based clear poly. Mix rate 1 gallon of paint with one quart of poly. My room is painted the same color gray without the poly and the ceiling is painted flat black. There is only one opening to the room and it is light controlled 100% with black velvet BOC curtains.

The room is a dual purpose room to be used as a lights out theater and also a comfortable lit media room for sports and TV. If it wasn’t for the second condition of usage I would have a 1.0 gain white screen or a very light simple gray .8-.9 gain.

I also have a DIY zoom mechanism that moves the ceiling mounted projector along an inclined rail. This is how I get enough zoom range out of the projector to a variable immersion presentation. Doing it that way maximizes my brightness at all sizes. I also shift off eco into normal lamp mode when viewing IMAX/Scope. Depend on the task lighting and screen size and 2D / 3D I use different presets and brilliant color settings.

This method has worked very well for me with my controlled ambient task lighting. I often get comments of disbelief that a projector can work this well with this much light in the room. Of coursed they are somewhat tricked to thinking the room is brighter than it really is.
