velvet left / protostar right.

I will compare the Protostar stuff to the Ebay stuff, I'm interested if it really is better, because if not, then why pay more.
I got impatient waiting on the screen, so I ran to Walmart and grabbed enough blackout cloth to make a 120" 2.35 screen.
The homemade screen came out surprisingly well (though not perfect), I very well may leave it as a second screen behind my new Electric Screen.
It would have been perfect, but I over-tensioned part of it and created 2 small waves (cannot see them with lights off). I think I can get the waves out.
I wasn't trying to actually create a 'good' screen, I was simply trying to visualize how the screen would work so decided to use TACKS and some blackout cloth as a quick solution.
I had the screen up in 30 minutes and it cost me $25 to buy the blackout cloth, and it looked pretty decent after I was done, was surprised.
I may go online and order some different DIY screen material and experiment with it. Need to try out some different DIY materials.
Blackout Cloth is a great way to setup a TEMP screen for anyone that is building an HT and isn't sure about the screen size or 2.35 vs. 16:9 or whatever. The blackout cloth only comes in 54" high, but it is enough for about 135" (or even slightly bigger) 2.35 screen.
I just don't see myself spending real money on another screen until I'm sure how to handle 2.35 switching.
I was also curious to how cheap blackout cloth would look against the HP 2.4 screen, well besides the brightness the HP screen is just slightly sharper, but not a huge difference.
I think the blackout cloth MIGHT have less texture in arctic white scenes, but didn't test much white content yet. The difference in sharpness was say 20% maybe, not huge but it was there.
I didn't do a same-room test though, as my HP screen and blackout cloth screen are in 2 separate rooms.
I have the HP in a gameroom but I think I may retire it soon, at least temporarily.
I'm going to Home Depot tomorrow to get some Foam Board, I'm just going to buy whatever is thinnest and cheapest and try that first.
