test shot last night with 2 layers of primer and 2 layers of top coat.

Using normal dvd player via component input; no upscaling; use camera zoom to show hd65 menu.

To naked eye under room lights, there are discernible slightly dark streaks on the plywood screen but in darkroom condition it becomes unnoticeable. Will put as many paint layers to finish the 1 litre bottle. The plywood is really soaking up the paint.

Will the plywood leave a lot of tiny tiny holes on the surface after soaking up the paint? I was thinking of using plywood and paint but afraid that the surface will be very uneven to produce a good and smooth surface.

I've built my own 8' x 4' plywood screen and hang it on the wall.

I once make a fix screen with a 4' x 8' plywood,the "mate white non-refletive" type ,the result is ok but even it's non-reflextive,it still reflex some of the light in some bright scene.I then cover the whole screen with a see through grey cloth and the result is better.However,i finally took down the screen becos it doesn't looks good in my living room(no room for HT).Just a frenly advice,if u are using 4' x 8' plywood,it's better u make some black border on left/right/up/bottom to make it real 16:9 measurement which definately looks better and more "pro" ,hehe thumbup.gif

I also think of another option for DIY screen.Buy a pull down screen,"dismember" it kaw kaw and take out only the screen.Cut it into a 16:9 size and nail it on a plywood.Maybe it works wink.gif

Another thing,i saw from the pic ,ur HT room,all walls are with shinning tiles cover to about 5' tall.If it's using as HT room,i think the sound will be very "harsh"becos of the reflection.It's advice to do some treatment on the wall,especially the 2 side wall and the rear wall.For this,u can use some curtain.....juz my 2 cents smile.gif

my HT room is previous kitchen thus the 5ft high tiles. I do intend to later on treat the walls; firstly to make it non-reflective by painting, either hang dark heavy drapes and/or build some acoustic panels using polywool.

I'll also look for some black velvet cloth to frame up the screen and attach using velcro so that can adjust for different aspect ratios. All these will only come after I finish the basics of the screen, wiring, mounting the hd65, painting the walls, install lights i.e the messy work.

The pic below after 2 coats of primer and 2 top coats of matt white. I'm already into my fifth coat today covering up all of the paint streaks that you see below.

Good progress that you have got there.

mys_terious, like rx330 said, better buy cloth and let the frame maker to do it for you.

Mostly finished wiring and laying cable casing for electrical, composite video, RJ45 and HDMI (in black).

The screen now have 5 coats of paint and looks quite acceptable to naked eye. Will paint at least 2 more coats to tidy up.

I'm now thinking of painting dark grey the wall behind the screen-not keen on a black wall.

The HD65 is already ceiling mounted using an ABTUS ceiling mount which has a quick release mechanism for removing the pj easily.
