2 Your current issue isn't a problem with need for pixel mapping but rather the scaling to a significantly different resolution and the fact that the 360 actually supports 1366x768 over vga while the PS3 does not. This does not mean it's pixel mapped (so far as I know pixel mapping is relegated to the dgiital world and VGA is analog) just that the 360 is not relying on the crappy TV scaler to convert a very awkward resolution change.
Basically the hideous conversion you see giong from your PS3 on your current display is not likely to occur on either console on a 1080p set even without worrying about pixel mapping largely because the scaling is going t oe done o nthe source (which is usually going to do a much better job than the display scaler) and 720p is actually goes into 1080p 1.5x which is a reasonable thing to scale vs trying to scale 1366 to 1280 which doesn't have a very clean divoisor.
This is all not even accounting for the fact that many games don't run natively at either 720p or 1080p on either console (often they run at weird resolutions to meet framerate goals or memory limits).
Basically wha tI am saying is don't worry:
Both consoles will look very good over HDMI regardless on a 1080p set in the vast majority of situations.
I briefly looked through that list and only picked out a couple of 1080 games. I suppose there technically are a few, the amount is very negligable.
The 360 is set to 1280 x 720 (720P) and when viewed in PC mode at 1:1 on the TV there is a small border for those extra pixels of the 1366 x 768 difference. I have tried to use other modes that fill the screen but that slight difference of 720P vs 768P immediatly makes the image look fuzzy. So it stays on 1:1 pixel mapping at 720 and looks best. Yes many 360/PS3 games "cheat" by lowering the resolution, and i can spot those in seconds. I don't even need to look them up I can pick out the true 720 games vs the ones that aren't. The ones that aren't 720P look "soft".
As far as 1:1 pixel mapping only for digital that is false. "1:1 pixel mapping" just means for every 1 pixel output it is mapped to 1 display pixel. 1280 x 720 pixels output maps to 1280 x 720 displayed, no fractions. Take any computer that uses VGA output and set the graphics card to output to something smaller than the LCD computer monitor's native res. You will see it immediately get blurry. It only looks sharp when the resolutions match. If you use any paint program and place a pixel or one pixel width line on the screen you can see it right away. It has been that way since fixed pixel displays have been connected to computers.
I do worry because consoles do look fuzzy and pixellated at non native resolutions, I have seen it. 1.5x scaling is no more reasonable than 1.25x, 1.125x etc as it is all fractional scaling and you have only whole pixels, there are no 1/2 pixels. To do this it has to do the one pixel correctly then blend/average the next ones next to it to APPROXIMATE the .5 pixel. This blending/filtering gives edges a blurred out fuzzy effect. The only thing that is an even divisor is if you do an even 2:1, 3:1 etc. People get used to that and don't care which is fine, but I notice it and I don't like the scaling and the artifacts from it in games. Video and movies don't look as bad from scaled up images for some reason though.Edited by DaveC19 - 12/5/12 at 6:18pm
