Just got the room done and Epson 8350 mounted.
The wall for the screen is new drywall and was painted aubergine (purple).
The picture looks good (HD TV or PS3 blue-ray).
Trying to figure out what to do with the screen.... cheap would be good.

Still not sure how it project white onto purple and I see decent white...??????

ideas on both issues most welcome...
Thanks Chris

If your drywall is smooth enough (no obvious texture) then you could probably just paint a section of your screen wall with an appropriate paint (a DIY screen mix or even a simple white or gray).

From what I have been able to find online "aubergine" is a dark purple color and there is no way you are going to be able to get decent color from an image projected on it.

What size screen are you using?

How much light will be on in the room that is not coming from the PJ? None, enough to see where you are walking (dim), enough to read a magazine (fairly bright)?

What are the colors of the other walls and ceiling in the room?

How far is the PJ mounted from the screen?

Hold a piece of paper up in the white projected portions of the wall you are projecting onto. Your opinion should change rather quickly. :T

Thanks,
The drywall is pretty good, but not perfect.
The projector is about 11ft from the wall/screen.
The light can be pretty much controlled down to very dim.

Not sure about the size yet, still playing - but pretty close to max from that projector distance.
The side walls are also the dark purple, celing a medium/light green (don't laugh).

yes, will try that....
and try to convince wife we need a white/grey screen on her "nice purple wall" LOL

It seems that every TV show come in a different format - there must be a setting to change-to-fit automatically. She'll kill me if there isn't. "4 blasted remotes is enough fiddling around to watch TV".

Thanks again!!

WOW... put up a few sheets of white paper.... SO,SO much of difference.

Another question: on the painted wall, it looks like I'm watching the picture through a bit of a dirty window from the texture. On the paper - perfectly smooth.
Is that because it's an eggshell paint on there right now? Or effect of just paint.
Are the paints recommended for screens "flatter"???

Thanks,
C.

A number of things could be causing the "dirty window" look, but I suspect it is either a rough area of dry wall or perhaps you are seeing some roller marks left over from painting where the paint didn't dry flat but left ridges.

The good news is that with your PJ and screen size (even at max. size you can only get a 113" diagonal 16:9 screen) you have lots of lumens available and don't need to go with a special screen mix and can use an OTS (Off-The-Shelf) paint to paint your screen area (or screen substrate if the wall is too rough).

The glossier, or more reflective, a paint is the harder it is to roll on without leaving roller marks. Eggshell isn't that much more glossy than flat/matte paint (depending on brand), but it will make any texture differences in the wall stand out more and tend to show roller marks more compared to a flat or matte paint. For your HT I would recommend a flat or matte paint.

If your wall has enough texture to give you that "dirty window" effect you have two choices of dealing with it (other than living with the problem). You can sand the wall down so the entire screen area is smooth or you could use a substrate of some kind and hang it on the wall. a 5'x10' sheet of about any sheet-good could be used, if your screen is 98" or smaller you could use a 4'x8' sheet (much easier to find). While any flat and smooth material can be used, one of the best to use is an expanded-cell PVC board called Sintra. This material is designed to be painted to make commercial signs so it takes paint very well.
