How does 1:1 Pixel Mapping work for consoles and 1920x1200 displays?

post #1 of 2
Thread Starter 
I'm looking into the Asus PA248q and noticed it had 1:1 PM. My current understanding is that a monitor with this feature if its turned on will only allocate the same amount of pixels on the monitor to the number of pixels it receives from the source so no stretching, shrinking, overscanning etc.. But how do most consoles work(let's say Wii, 360, and PS3 for this case). Does the output on the monitor depend on what resolution the game is being drawn in, or do consoles have one set resolution that send out, but draw the game in a completely different? I image that if a console sends 1080p to a 1200p monitor that there will be a black box around the picture if there is no additional overscan or stretching being done.

From my experience with consoles on PC monitors you can get stretched image, as the games and menus on the console is usually 16:9, where your monitor would be 16:10. So you would get a black stripe over and under the picture. If you have no scaling at all, you will get same result most likely. On bigger resolution monitors you will get black around the whole picture without scaling on.
So basically 1080p signal from console to 1200p monitor would only give black on top and under, as its almost the same resolution 1920x1080 vs 1920x1200. This is from my experience with a 360 at least, I can not speak for the others.

When it comes to stretching, I think most consoles do this as many 360 games are rendered in 576p, and you can imagine how small that is. So I think they have some native scaling from the console.
