For example JVC RS 40 has 1300 lumens and if I buy 2.3 gain screen, does it good enough? I see lot of recommendations from the posts to go for highest screen size possible.
First off, be vary weary of manufacturers brightness rating, much less with JVC, however even JVC must be at the closet throw ratio [distance from projector to screen] and wide open iris. other manufacturers, dont even trust them way off.
First I think we would need to know if you plan on calibrating your projector? As this will lower the lumens a projector outputs. Also how you like your image?[bright like plasma, or like in the theaters or somewhere in the middle, or maybe you want more headroom with being able to go bright but watch at a dimmer level to save on buying bulbs]
About the high power vs matte white... A matte white screen, such as caradas Classic Cinema White Screen Material which is vary affordable as well, is a great screen as well in place of the Stewart Studiotek 130 G3. I will admit the Studiotek 130 a lot of people have mentioned is basically the best angular reflective screen with gain one can get; gain of 1.3. Its the industry standard to be exact. however one pays a hefty premium, as they make there screen in house with better quality screening etc etc. With a matte white screen you get great uniformity in the brightness of the screen (not brightness brightness, but the uniformity of the brightness), with no sparklies on the screen due to no gain. The High power is unique as well, since this is one of the few screens with gain, that do not hot spot [uniformity great no matter where you sit] and has virtually no screen texture. The only downside is viewing angles, but if you sit center of the screen it should not vary. Also projector placement needs to be around 1.5-2.5 feet above your eyes.
With the High power its basically the same, but with high brightness and with better ambient light rejection [no light spills to side walls, room doesnt have to 100% light controlled]. But since you have 100% light controlled room, its not needed basically at all. I like the high power since its gives you lamp room. You can clamp down the iris of the jvc to the suited foot lambert/brightness of the screen you want. When bulb ages, just open up the iris for more light. However, some might say its got some color shift if you move to a different seat...I think Jeff Meirer [screen name UMR] says such as cyan can color shift. But if you plan to always sit center to the screen, it really dont matter once you calibrate your projector.

Just a note: screenshots should not be a factor in purchase as there are to many variables in the way.
I more than likely confused the matter worse for you. Sorry im very tired and I have to go to sleep for work tomorrow.
One more thought though, if your on a budget and want even cheaper screens, look at Elite screens. Very cheap. Although I really dont know much about them, but stories about them are not that bad for the price you pay for them. Just a thought.
