I've committed with going with an a-lens in my theater and have a question for the a-lens users in the forum...I do enjoy playing the XBox and PC games in the theater however.


For those who leave their lens in place, how does non-video content (computers, game consoles, etc) look when horizontally compressed for the A-Lens?


Reason I ask is I am trying to make some final decisions on mounting of the lens (fixed vs slidable) and am also trying to make a final decision on curved vs flat screen...


I'd make a joke about being choosing between being on PIN(cushions) and needles or being over a Barrel here - but everybody would just groan :p


For ref - plan is currently a 2.4 screen 48" tall with a throw around 2.25x 16:9 width and a Lumagen for processing.

When you scale the image for optically expanded 16:9 (using 4 x 3 + A-Lens), you are discarding 25% of the H-Rez. For PC use, I tend to let the desk top get stretched so that all 1920 x 1080 pixels are being used. Games are really not that different to video, and where I find this scaling/optical expansion process to be quite exceptable.


If you were going to move the lens and watch more 16:9 program than Scope, I would suggest a flat screen. If you are happy to leave the lens in place all the time and scale for CIH, then you might as well use a curved screen to correct the pincushion from the A-Lens. I would not recommend moving the lens for use with a curved screen. Others will disagree no doubt.

I agree - general computer use won't be impacted much and any good video players support aspect correction...of course Youtube videos of tap-dancing hamsters and what not may not be right - how ever shall I live?

My concern here was how text and line-art come out with the scaler. It is just a 4->3 conversion so I imagine it scales pretty well but I don't have my scaler yet to play around with it...
