Can't find scaling options in ATI CCC

[sdraw107]

Hi,

I have a Radeon 9600 and a FireMV 2200 running on Windows XP, with 22" AOC e2243Fw widescreen monitors connected via DVI-D single link cables. I'm having issues with black borders when I select any resolution other than 1920 x 1080. Instead of filling the whole screen, it simply puts the smaller resolution in a box in the centre of the screen. The resolution I am mainly interested in is 1600 x 900.

I have spent hours googling this problem and almost all the solutions I see suggest playing with the "scaling options". However I do NOT have this tab anywhere no matter what version of CCC I install, including the latest version. I *know* the monitor is capable of displaying 1600 x 900 because it works fine on the Radeon 9600 via a VGA cable.

I am not sure why, but the problem goes away on the Radeon 9600 if I reduce the refresh rate to 50hz. Unfortunately there is no 50hz option in CCC for the FireMV.

Basically, I am desperate to find the holy grail "scaling option" which so many others seem to be using to fix black border problems. But it doesn't seem to be anywhere!

If you have CCC2 then the scaling options are under My Digital Flat-Panels -> Properties -> Image Scaling, tick the Enable GPU scaling box and choose what option you want.

In the older CCC it is buried more, you have to right click -> Properties on the small picture of the monitor in the display section.

Thanks for the reply. That's not the screen I'm looking for though. I already have that option set to "scale image to full panel size", but it doesn't solve my problem. I am looking for the slider which lets you set the overscan/underscan, as described here:

The screen I have (which you described) is this one:

But the one I am looking for is this:

i believe its in teh display manager panel. the olne that shows the active screens along the bottom of the pnale, each screen having a little triangle in the top right corner (i think). click on that triangle and you should fine the scaling option.

I've seen other posts describing the screen with the panels having triangles you can click, however my CCC version is nothing like that. My display manager panel looks like this:

im sorry ive just re-read your op, it isn't the scaling slider that you want. gpu scaling IS the feature you want and you need to turn that on.


The scaling slider is only applicable when you are using the displays native resolution AND you get black borders. This isnt your problem. you are getting black borders with anything < 1920x1080 (your displays native resolution) meaning neither your gpu or the display is scaling the image. When the display cant scale, this is when you turn gpu scaling on.

If it doesnt work with gpu scaling on, then i can only assume there is a problem with the drivers and the only other advice i can offer is to make sure you have the newest available drivers for that card.

hope this helps!

Thanks for the explanation. Yes, I am getting black borders when I choose resolutions which are under the native resolution (i.e. less than 1920x1080). I have "scale image to full panel size" selected as per my first screenshot above, but it has no effect. I've tried installing the latest drivers multiple times, no effect.

I *know* the monitor is capable of doing this because it works fine on a VGA cable, but the quality is poor on that cable.

I've ordered a cheap Nvidia card from Ebay in hopes that this will take care of it, as the stuff I've read on various forums suggests that Nvidia drivers don't suffer from scaling problems as much. So I'll see what happens there.

long shot but is 'Enable GPU scaling' actually ticked, as it isnt in the shot?

Well, the trouble is its an old card that's no longer supported. Ati did have a lot of trouble with scaling, thats true (and some drivers still forget the setting when the pc is rebooted) but by large those issues are fixed. Im sure the nvidia card will sort the issue though

Yeah I noticed that too. It doesn't retain the tick in "Enable GPU scaling" (if I tick it and click apply, the tick disappears) but it DOES remember which of the radio selections are enabled, so I am able to change between "full panel size" and "centered timings".
