If you don't know what I'm talking about, then you probably don't know the answer to my question anyway. By the way, I am using a Samsung SyncMaster 730B 17" LCD Monitor with a 1280 x 1024 native resolution, so I cannot enable 1:1 pixel ratio scaling from my monitor, unlike Dell LCD monitors, so I must rely on this feature being available and functional in the video card drivers.

Thank you very much for your help.

This has to do with your monitor and nothing else. Sorry to burst your bubble but this has nothing to do with your video card. "so I must rely on this feature being available and functional in the video card drivers." Your blaming ATI for your monitor's downfall? Sounds silly to me

Then why do Nvidia's drivers have this function working perfectly fine on all monitors?

Indeeed. If the driver provides "padded" output then the monitor shan't detect anything to scale even if that is its misguided predilection.

Has this problem been fixed yet with the recent ATI Catalyst 6.1 drivers? Thanks again.

It doesn't seem that way, but I have to keep asking anyway.

Thanks for all your help so far.

I'm also eagerly awaiting a fix. I don't have enough cash to buy a new video card, and my 9700 pro can't handle native res on the recent games. BF2 looks horrible scaled from 8x6 to 12x10. Although, admittedly, other games look fine scaled.

Thank you.

It's not fixed and I don't think ATI has any plans to fix/change this. My kid has a X1800 XT and he's using the new drivers and the lower resolutions still scale to fit the screen.

I'm like you, I can't stand scaling any lower resoutions. I'd rather look at a smaller image with black bars then scale it.

I haven't had a problem with this since switching to NVIDIA.

I would have had an Nvidia card long ago, but I got a free X800GT, so I really couldn't pass that up...Even scaling from 1280x960 to 1280x1024 still looks bad. The text gets all mangled and the graphics even look worse, especially with the aspect ratio stretch.

Don't know what you guys are talking about...

I have no trouble scaling with my X800GTO2. It scales just as nicely as my NVidia 6600GT does. Just open up the Catalyst Control Center, go to digital panel properties, and set the image scalings to "Use Centered Timings". The image will scale, using black bars when needed.

You need the Catalyst Control Center in advanced view, and I'm using a DVI connector.

Which drivers? Because I'm doing the exact same things and my image scales to fill the whole monitor, except at some odd resolutions. All the main popular ones get stretched.

I'm using catalyst 5.12. However I've only used it to scale to 1280 x 960 resolution to get a nice 4:3. After playing around further, it seems like the only resolutions that scale properly are resolutions that have one side use the entire screen. 1280 x 720, 1280 x 768, and 1280 x 960 all scale properly. None of the other one's do. Gonna try out the latest drivers...

Hey, thanks. That's how it is now. I haven't upgraded my drivers since 5.10 (too lazy), but I was thinking about trying 6.1 and see if they fixed at least one resolution yet, so I think I'll go do that now. Right now, for me, 1280 x 720 and 1280 x 768 are 1:1 for me, but not 1280 x 960. Also, there are some really weird lower resolutions (that I can get to in CCC) that are 1:1, but the following scale to fill the entire panel:

640 x 480
800 x 600
1024 x 768
1152 x 864
1280 x 960 (with Catalyst 5.10)

I'll post again when I download 6.1...

I just tried out 6.1 and got the same thing. 1280 x 960 still fills the entire panel. I'm waiting for your results, kmmatney, with 6.1, and if they are the same as mine, then I'll try 5.12.

Thanks so far.

So, before you go on another round of ranting at the driver software, have you established yet whether or not your MONITOR is even capable of non-scaled output for low resolutions? Yes or no?
Have you understood that the driver has NO CHANCE WHATSOEVER of making it happen if your monitor doesn't support it?

Listen, a few resolutions DO work at 1:1. The only problem is they are crazy nonstandard resolutions that no game supports, like 800 x 480 and such.

Now, when I'm running at a resolution that actually works with 1:1, if I check my monitor's OSD, it says it is running at 1280 x 1024, even if it is a lower resolution, like 800 x 480. This obviously shows that the video card is actually outputting an image with a 1280 x 1024 resolution, but with black bars on the sides. For whatever reason, this only works with a few resolutions, and I'm beginning to think ATI has intentionally made it that way.

In any case, this easily proves this problem is one with the drivers, and not with my monitor.

I built a new pc this weekend, now I have a X1900XTX card, and I couldn't get 1:1 to work no matter what. Via the Catalyst control thingyl.

Then I messed with my OSD on my 24" LCD, what did I find? Image options, which had a scaling setting. I put to 1:1, and 1:1 works great now for every resolution I've tried under native. This may help you out.

Note: my monitor only lets me set to 1:1 when I am in a game that's using non-native resolution. So run your game, then try messing with your screens' settings for scaling. It should remember them next time you play the game, or use that resolution. Mine does. =)

I just got a X1900XT aswell, before I had several Nvidia cards.
I have a Samsung 930BF 19'' 1280x1024.
With Nvidia i could scale 1:1 or keep the right aspect and make it fill the screen width (e.g. 1280x960 or 1024x768 were displayed with small black bars)
Most important for me is to have 1280x960 running in 1:1.

Now the interesting part:
Cat6.2 set to "use centered timing"
1280x960 and 1024x768 both fill the screen compleately

Even more interesting:
1280x720 seems to scale right BUT is scaled like I had a 4:3 moitor, so in my 5:4 monitor it is NOT displayed 1:1 but streched about 1cm in height.

Is there anyway to fix this totally wrong behaviour ?

It all worked perfectly with my 7800gtx.

Please Help !!!!!!

Using analog or DVI? When you auto-adjust the analog it may just chop off all black parts.

The OPs monitor does not have these options, that's why he's asking about the drivers.
