Pre-certified Catalyst Reference Drivers

AMD/ATI Support now offers a new version 12.2 pre-certified Catalyst reference drivers for AMD/ATI GPUs. These offer a number of changes and enhancements, along with the following explanation of what pre-certification represents: "The AMD Catalyst™ 12.2 Certified driver (It is the same driver as the Catalyst 12.2 Pre-Certified, but will be officially Microsoft® certified) will be posted in late February or very early March 2012."

Another reason I don't mind being on VGA instead of HDMI is the notorious Crysis 1/2/Warhead "24Hz bug." Those three games will bloody well start up at 24Hz and there is little to nothing you can do about it. They're unplayable like that. VGA connection? Bug goes away completely.

Some TVs have two different modes for HDMI. One is PC, the other is AV. Also, sometimes the stretch(over/underscan) option is on in the Catalyst Control Panel and that muddies it up and makes it look like crap.

Well, Windows' screen resolution was telling me I was at 60Hz and the overlay the TV would put up on a change mode said the mode was 1080p - not 1080i - so I don't know what the issue was. But, like said, it works perfect now so I'm not inclined to go yanking cables and pulling out the voltmeter..

It was probably some type of filter the TV was applying to HDMI inputs, but, I *really did* look around for everything I could find and nothing fixed the image quality and immediately when trying VGA it was fixed. I'm at 1920x1080 60Hz with the VGA and it's all good.
Don't forget to check video card itself, it often defaults to interlaced, not progressive (1080i instead of 1080p), which can make it look ugly, especially text.

Also, there is ZERO difference between $45 and $10 hdmi cables in how well the signal is received. Unlike analog which can fall off quickly from crap cables, with digital, the signal is either there and working, or not there and not working (or working incredibly badly).

If you've noticed on digital broadcasts how the stations that are close come in much better than they used to with analog, but far away stations have lots of crap blocks and its almost impossible to watch something you might have barely been able to watch as an analog broadcast? And with sound, either the sound is very good, or the sound cuts in and out and is hardly watchable (unlike analog which might have static but still be watchable)? Thats due in part to the difference between analog and digital.

Anyway, bottom line, don't waste your money. Unless the cable you bought was the absolute worst one in the world, you won't notice a difference. If you are determined to try, get it at a place like best buy where you can return it when there's no diff

If a normal VGA cable is higher quality, there's probably something wrong in the settings for the HDMI input on the HDTV or the HDMI output on the video card. Normally, at BEST a VGA should be same quality.

Somethings to look for are a setting that says "pixel" scaling (you want that on usually) otherwise the screen often scales and not in a good way to try and fill the screen to the edge. Also on the video card, make sure its not outputting 1080i (interlaced) on hdmi output. That's a common default setting.

I'm sure there's other things too, but those are first 2 I can think of off hand that really screw up how the picture looks on hdtv through HDMI that might not show up on VGA.


Often new HDTV's are factory set defaulting on with filters on that screw up stuff, like sharpen/smoothing filters or de-graining filters (which I've found make movies look plasticy and fake to remove the director intended grain). Settings like this are named all sorts of things, and often sound fairly innocuous.


On the other hand, if you don't mind the length limitations of VGA, don't mind having a separate often analog audio cable, and you can't be bothered to figure out the problem, enjoy it as you already have it

I have these drivers installed and the packaging has them as Catalyst 12.3. Here's a screenshot:

I have a VGA display because I'm connected to a HDTV using that cable. It's much higher image quality than an HDMI @ 1920x1080 believe it or not.
