ATI 480 wont do 1920x1080 in VGA

[FatRakoon]

This might sound a bit silly, but I have the 3 Living room PCs running through a KVM.

The KVM is unfortuantely VGA Based, and so far, its been fine, and has not really been a problem for me. My Monitor is capable of 1920x1080 and I hve been able to do some adjusting / cheating in order to get things to play nicely at this rez.

The snag is, that I have just bought a Radeon 480 and I just cannot get it to work at 1920x1080 at all! - I have it at 1600x1200 right now, but it does not quite look right. I have managed to get it to 1920x1080 interlaced, but of course thats ridiculous as it was 30Hz and not 60?

Previously, I was able to use the Catalysts to get it to force the rez to 1920x1080 but now, the cats wont even try, it says there is no Virtual desktops or anything.

Anyone know how I can force it?

The previous card that this PC had was a pair of 7770's but also the 6950 card was ok doing that as was the 5940 dual one, and also the GTX 680 and 970 cards allowed me to go at 1920x1080, but this 480 wont go?

For what its worth, I am using a HDMI to VGA adapter, but again, this was also used previously too!


Please help!

You can't. Both companies have moved past VGA with the newest cards.

Don't know about this specific case, but something like the Custom Resolution Utility (http://www.monitortests.com/forum/thread-custom-resolution-utility-cru) can be used to manually add resolutions. This is normally used to force monitors to operate at different specs than they're designed, but may also help here.

I accept that VGA is old hat now, but the thing is, that Im using the DVI or the HDMI ports and then VGA is via an adapter...
I only need the VGA by way of the Physical connection rather than a limit of the Spec.
But yeah, DVI and HDMI are a digital on this card and it has no Analog output at all, so yeah, thats quite probably a limit that I cannot get around perhaps?

But then why am I able to do it on other cards, just not this one?

I will have a look. The monitor is happy to run at that resolution, so its not like I am wanting to force it to do something it wont like... Its just that I cannot get at that particular rez because the driver opr rather the card wont let me?

Ok thanks guys.

Just to note, that utility works brilliantly!

Many many thanks.

Admittedly, I kept getting interlaced mode and I could not stop that from happening, and tat did irritate me for a short while, but I have just restarted the PC and I saw the screen was a square one, with black side-borders, and so, I went back to change the rez and I saw the 1920x1080 that I had put in, but this one also had Recommended mode on it, and so I selected it and hey presto! - non interlaced crisp display!

Many many thanks my friend. I owe you one.

Oh god... After about 10 minutes, the PC kept blanking out the screen and making the Connect / Disconnect sound over and over. MAde it completely useless to work with.

I have tried all mind of tricks, and even fully reinstalling the drivers etc, but nothing worked and so I am back on this odd 1600x1200 again!

I have now got 3 choices.

1 - Stick with this rez
2 - Put the old card back in and have a good screen again
3 - Waste a small fortune on buying a KVM that allows HDMI.

I think I will go with option 2 actually and use this card in one of the Lan mamchines and use it for proper gaming!
