Right.. well this is mostly copy/pasted from my entry on tomshardware because I keep thinking a dedicated forum would ever actually get responses.

I formatted my computer and put Windows 8.1 on. I previously had Windows 8. Windows 8.1 AND my Sony TV both think it is running at 1080p and it is NOT running at 1080p. Both Ubuntu and Windows 8 correctly reported the resolution as 1080p while it was actually running in 1080p, but 8.1 can't put it in 1080p yet thinks it is 1080p.

There was no hardware change, no cables moved around, nothing more than the re-install of the OS on my primary hard disk.

I have a secondary screen which is a 32" 1080p Sony Bravia TV. I understand that TVs are not intended as monitors however this was working flawlessly prior to the install. Not even the settings on the TV will have changed, only the OS.

I know what you're thinking, that if both the TV and the PC claims it's 1080p then surely it actually is. Well, it's not really: If I run any 1080p app it gets cut off the bottom and right sides of the screen and traverses onto the second monitor. Everything looks fuzzy from being lower res. If I make an explorer window nearly 1920x1080 so it reaches near the borders, then move it onto the TV it will not fit on the TV.

Relevant Specs:
Windows 8.1 x64
Sony Bravia TV - KDL-32CX520 Model # (Secondary)
Asus VX238 24" Monitor (Primary)
Gigabyte R9 280x 3GB Video Card

What I have tried & Notes:
- Changing resolutions
- Isolating the TV makes no difference.
- Switching which screen is primary/secondary no difference.
- Re-installing the latest Catalyst graphics drivers. Prior to reinstall I had the *same* ones which are definitely the latest as I had recently updated those days before formatting.
- Re-seating the graphics card
- I have a Playstation 4 hooked up on the other HDMI input and that definitely hits 1080p properly so there was no insane coincidence that occurred while I installed Windows 8.1

Looks a lot like this:

http://www.eightforums.com/drivers-hardware/33385-wddm-v1-1-driver-ati-hd4600-windows-8-1-clips.html

But the solution ... basically to use the default Windows 8.1 driver or upgrade your card ... aren't great.

Er, yeah..

I use Windows 8 because I find it's a bit faster. But not faster enough to warrant this and the fact I just found that you actually can't get rid of the bloody desktop from alt-tab menu. It's the first OS I've ever had to stop and check the alt-tab menu to make sure the desktop didn't sneak up behind me again to minimize all my applications and obliterate any flow I'm getting while coding. Made it revert to XP alt-tab and the search pane and weird crap started showing up in it.

Between these things.. not worth it. Back to windows 7 :/

This alt-tab crap better not become a thing from Microsoft. If it ain't broke don't fix it, not if it ain't broke screw everything up and change the standards instead of fixing it. I fear Windows 10 and the future.

If only I didn't need specific applications that don't run on Linux, but that will likely NEVER be the case. Windows forever whether I like it or not (yeah, it's definitely a not).

Windows 7 is the new XP, that's for sure.  It is not going away any time soon.

BTW I don't see Desktop in my ALT+TAB in Windows 10 so I don't fear the future

Fuzzy comes from when the HDMI connection switches to YUV instead of RGB. Better for compressed video since it will band less, but the subsampling makes things look like crap.

If you are getting stuff cut off, that is the picture size on the TV you need to change to just scan or whatever sony call that. The same button to make 4:3 stuff look correct should cycle thru to a mode that doesnt stretch things.

Both probably happened when the card decided to use the consumer electronics modes rather than the vesa video modes. I never found a solution for it on my intel based desktop PC short of running it thru a HDMI splitter that nicely messed up the negotiation to only showing the VESA graphics modes.

By the way if you have graphics driver you should be able to fix it.

Ati one is called catalyst. Click the right menu and you can adjust the "zoom" / screen size on your tv

Would certainly pay to have a look in your amd catalyst controls and adjust under/overscan.

That was the very first thing I did.

Back on W7 now and no issues.
