Registry key to change TV picture position limits?

Hi,

Is there a key or tweak of some kind that allows you to overcome the limits of the screen positioning controls in the ATi Display Properties>>>Advanced>>>Displays tab?

At the moment I have an HTPC with an AIW 7500 ouputting 848x480 to a 16:9 Panasonic TV and it looks gorgeous. The only problem it that I cannot move the picture any further over to the left (even through increasing the horizontal size) and you can see the edge. On a PC monitor this wouldn't be that much of a problem, but on a TV you get geometry distortion towards the edges of the screen (which varies depending on luminance) and it is rather distracting when watching DVDs etc. Overscan is no good as that works on the horizontal plane only. Neither is changing to something like 856x848 - that just enables a virtual desktop.

Many thanks,

MuFu.
 
I know this thread is 11 years old, but I really wanted to know if there is a registry setting or tweak to overcome the limits of screen positioning, I'm with the exact same problem as him, haha
 
If you are using a modern TV with HDMI couldn't you just use overscan to fit the image? Just note if the TV isn't set to the right resolution/Hz the overscan option will be faded out.

If you are using an ATI/AMD card that's old, the overscan thing is supposed to fix it, but it only worked for me on some drivers (older ones).

I recommend a quick google. If you still haven't found a fix, bump the thread and I'll take a gander at reverse engineering what I did back then.

What was happening on my old 4870 was I would get an image in the middle of my screen (using half the screen, with giant black borders all around).

It was terrible and it took weeks of research to resolve the issue.

thanks Sazar. If I use overscan, the left and upper border are perfect aligned with the corners of the screen, but the bottom gets stretched offscreen and the right has a black bar. Using the underscan settings, I can align almost everything perfectly with my screen, except the left side - I move the picture all the way to the left, but there still is a black bar, and stretching horizontally doesn't solve it either. That's why I asked if there was any way to overcome this limit. Only this 848x480 resolution give me this problem, but that's the one I need. Thanks for any help.
 
I think most TVs have the option to rescale image etc. Why need a registry key?
