The WSGF had the opportunity to sit down and chat with AMD about the new Catalyst 14.6 update. This update is not to be missed, and brought several new features to the virtual table (desktop):
  • Mixed Resolution Eyefinity
  • One-Click Eyefinity Configuration
  • New Linux Drivers/Support



Click or the "full article" link to watch on the WSGF.


The key feature here is obviously the Mixed Resolution Eyefinity. It allows users to pair different res monitors into a Single Large Surface (SLS) for gaming. If you have a mismatched set of monitors - 1920x1200, 1920x1080, 1680x1050 (or others) - you can now put them in a "full screen" Eyefinity group for gaming.

Additionally, you can set up screens of different aspect ratios. Primary use cases are a 21:9 flanked by 16:9 panels, or a 1920x1200 flanked by 1600x1200 panels. While we aren't yet at PLP support, these new configurations are one step closer.

The audio "podcast" includes slides from the AMD press deck. AMD reps were:
  • Robert Hallock - AMD Technical Communications
  • Shane Parfitt - AMD Technology Manager, Displays
  • Anthony Brown - AMD Software Developer

I have been experimenting with this the last two days. Right now I am using the expand mode so I can use my middle monitors 2560x1440 res. The two outside monitors are 1680x1050. There are some games that the hud or some features are lost because you are losing that part of the screen. The nice thing is that on the games that have the hud etc on the middle monitor everything is great. I am ok if I lose the 400 res on the bottom of the outside monitors. For fps your using the outside monitors for peripheral vision anyway.

I used to have 3 1680x1050 monitors but on the games that eyefinity did not work or was poor I wanted a much bigger screen. I got a U2711 2560x1440 screen about 2.5 yrs ago. This is one of the reasons that I have not been on WSGF for awhile as I have been playing on that screen.

When I would try to play eyefinity it would then default or "fill" to the 1680x1050 screens. It worked ok but now my nice 2560x1440 middle screen was at 1680x1050 scaled. So the most important part of my vision while gaming was at 1680x1050 instead of 2560x1440. I saw more in total width wise at 5040x1050 but gave up a lot of res in the middle screen where res is the most important and 400 or so res in height.

Going back to the new expand mode> when I am gaming at 5920x1440- {1680x1050--2560x1440--1680x1050} The middle res is 2560x1440 and looks exactly the same as when I just use the single screen with the same res. The big issue on expand is game huds or for example some fps game where you pick a gun class or loadout that is on the outside monitor either on the upper or lower part of the screen. You may not be able to see anything at all and the game is unusable even though the game is ok once you are actually playing.

Now on to the new FIT mode. In the video it shows a 1600p monitor with the top not displayed matching up in a nice straight line with the 1080p monitor. The issue I am having is with my 2560x1440 monitor is that the dpi is much higher on that screen than the 1680x1050 monitors on the outside. For example and I think this is very important:: My 1680x1050 monitors have 11.75 inches of vertical viewable screen. But my 2560x1440 is 13.25 viewable height. Only 1.5 inches diff. in viewable height. BUT there is 390 res difference. So if you do a fit setup my middle monitor has a narrower viewable area then the side monitors. It is taking from the top AND the bottom of the middle screen because 1050 res is way different at 110 ppi than say 85.

I have said a lot here but these are some of the issues I see currently.

To be honest this will be all for naught when this comes out. I am getting one of these for sure.

I want one too. And with new mixed res Eyefinity, you could flank it with a pair of 27" 2560x1440 panels. Just saying...

Right now I have my 2560x1440 U2711 for sale. I will be able to sell it at work. I also have 3 1680x1050 screens that I am going to sell also. I will keep my 24 inch 1920x1200 on the side in portrait mode and my other 1680x1050 on the other side of the 34UM95 in portrait mode. Then I will be set.

That was one of the first things that came to mind.

Also <3 for bringing up Linux. I'd love to be able to pick those guy's brains a bit on any of that.

Has anyone else tried installing the Linux 14.6 beta drivers? I am having issues trying to get them to install. Had issues with running the command (su authentication would return a failure, even though it is my password). When I "sudo -s" into root, it would error back telling me to check my fglrx-install.log which told me I need to instal linux0headers-3.11.0-14-generic. Running "uname -mrs" in terminal shows that I do have the 3.11.014-generic headers. Any knowledge if there is an AMD PPA?

And yea, if we could figure out the time, I would totally be up for talking with some of them.

Interesting, this potentially paves the way for PLP support then in theory, at least at a driver level.
Guessing some additional hardware magic is needed to tie in the PLP displays into an SLS.

What about some EDID magic ? Is the rotation aka P or L marked in the EDID file? or does the GPU driver realise this via vertical refresh rate ?
