WDDM v1.1 Driver for ATI HD4600 on Windows 8.1 clips

So I had been running Windows 8 since release with the official ATI Catalyst drivers and was able to run in 1080p with no issues. I upgraded to 8.1 yesterday and it replaced my drivers with the WDDM 1.1 driver. The problem here is my display is clipped from all sides. If I switch the resolution to 1776x1000 everything displays as expected. One thing to note is that the monitor showing up is a "Generic PnP Monitor". I have a Samsung HDTV plugged in. I don't remember what this value was in 8.0.

I tried installing the latest Catalyst drivers for Windows 8x64 released in 1/2013 but it's not detecting any hardware and thus not installing the drivers. Is there anything I can do right now to view in 1080P or do I just wait for AMD to release 8.1 drivers?

That should not matter.

Download the AMD auto-detect utility to make sure they are the latest and you can also check Windows Update for optional drivers as well. Now, I don't normally recommend Win Updates as a reliable source for driver updates but I was surprised to find an Intel update that was labeled as a WDDM 1.1, 1.2, and 1.3 version so maybe they have a similar update for your AMD version. Try both and good luck.

First off, it's unlikely that AMD is going to release Win 8.1 drivers for your card because it relegated the HD 2x/3x/4x-series cards to legacy status a while ago.

I have an AMD 4290 and discovered, through trial and error, that I could install the Catalyst 13.1 drivers (but nothing newer) using the workaround of updating the MS WDDM driver by selecting the INF file in the appropriate AMD drivers directory. Trying to install the usual way (using the AMD driver installer) did NOT work -- and, the autodetect sent me back to Catalyst 12.6.

Mark is right. I too have an MSA Radeon HD 4... series card in my HTPC, and the upgrade to 8.1 changed the driver. My images are also clipped on the sides and the option to adjust which came with the Catalyst suite no longer exists. My choice seems to be either to continue with Windows 8 or change the Graphic card to Sapphire ATI 6670 1GB DDR5 or MSI ATI 6450 2GB DDR3 which are both available though the MSI 6450 is almost half the price of the 6670. The new ATI drivers I understand support all series above 5000 for Win 8.1 . Also this PC isused primarily as an HTPC for full HD and other videos etcetera. For such purpose my understanding is that the MSI 6450 would be more than sufficient or would the 6670 give some extra filip. Appreciate all responses.

Just to be clear: In the thread I linked to above I solved the problem by just deleting the video driver leaf item from within: Control Panel, Device Manager, Display Adapters, the “AMD Radeon HD 7560D” driver - and rebooted.

The original 8 generic video driver was installed. So I'm running HD with the 8.1 upgrade just fine. Clipped-letterbox problem solved.

Win8fait's solution does not work for me as I have to use the overscan utility provided in AMD drivers to fill the entire screen of my large screen TV. The generic Windows driver is unable to do so.
