10.3: Eyefinity Bezel Correction, Grouping, & Per-Display Controls

Following CrossFire Eyefinity support across the board in Catalyst 10.2, Catalyst 10.3 finally enables per-display color controls - which is particularly handy if you don't have a set of identical displays:

Each display gets color correction, saturation, brightness, contrast and temperature control. To test this I had a triplet of identical Dell 24" displays connected via HDMI, DisplayPort and DVI. An artifact of the premature nature of the drivers was that I couldn't control color temperature on the display connected via HDMI.

Another feature for users with sub-optimal display setups is bezel correction. If you have particularly thick bezels, or displays of differing bezel thickness, Catalyst Control Center now lets you compensate through a fairly easy to use tool.

What you're seeing above are two displays, the bezel divides the yellow triangle. Using the controls on the right you adjust to compensate for bezel thickness. Below is what it looks like on all three displays:

The one key feature that AMD needs to enable support for is real-time aspect ratio correction in games. Unfortunately, despite AMD's efforts, Eyefinity remains something that is poorly supported by many important titles. Yes you'll get full resolution support in most games, but what you'll end up with is a super wide resolution with content stretched to fit it. Currently Widescreen Fixer is one of the best ways to force aspect ratios not properly supported by games.

The easiest way to get around the aspect ratio issues is to simply run in 3x1 portrait mode:

My three 16:10 panels rotated in portrait mode offer a 1.875:1 aspect ratio, not too far off of the 1.6:1 native AR. In landscape mode the aspect ratio is an out of this world 4.8:1 and causes many games to let you play in a very high resolution distorted world:

AMD has apparently done nothing to fix this as recently released titles like Bioshock 2 are simply unplayable in 3x1 Landscape Eyefinity mode. The most important Eyefinity feature we're lacking is developer support at this point. AMD has had a tremendous headstart over NVIDIA in the DirectX 11 GPU generation, to not have this working by now is unacceptable.

The final Eyefinity features supported by Catalyst 10.3 are support for multiple groups and fast switching between Eyefinity modes. Multiple Eyefinity groups could be used to support configurations like one single large surface made up of two monitors and one additional monitor as a desktop extension. This becomes more useful as you get into 4, 5 and 6 display configurations which should be enabled sometime this year.

It's pretty quick to switch between cloned and single large surface display mode (in case you're tired of your start menu being multiple feet to your left but still want to keep the immersive gaming mode). Just a right click and an unnecessarily deep couple of menus and you're there.

You're also supposed to be able to define profiles that include your Eyefinity configuration, to allow you to switch between 3x1 and 1x3 for example if you happen to be some sort of crazyperson and like to reorganize your monitors frequently. Unfortunately neither groups nor profile switching worked reliably for me. The last profile I would create seemed to overwrite the previous one. AMD has until March to finalize the drivers, so I'm guessing these bugs will be gone by then (famous last words).

    It looks like ATI Catalyst 10.3 Beta leaked out. I am pretty happy with it. You can download it here ( http://www.geekmontage.com/ati-catalyst-10-3-beta-...">http://www.geekmontage.com/ati-catalyst-10-3-beta-... ) I see it on a few other sites too, just do a google search.

    Well dana i have placed my order for it. Hope that it 'll be a very nice product. Thanks for sharing.

    Is it just me, or did ATi not talk about OpenCL support at all?
    As far as I can tell, it's still not included in the 10.2 drivers, I still need to install the Stream SDK to get the actual OpenCL runtimes.
    This is not acceptable for distribution to end-users. They will just need to include the OpenCL runtimes in the driver package.

    Mobility drivers for HD-series graphics cards sounds great... but what about laptops that have the FireGL-branded cards, such as mine?
    For example, HP's latest Win7 driver for my laptop is 8.632 -- which is really old.
    My ideal case: mobility drivers that offer the professional features (such as "10-bit pixel format", though I don't have a display capable of using that) -- even if they're not ISV-certified.

    Also, ATI has had some form of quad-buffered stereo on the workstation cards for a while; it's cool to see it now expanded to cover consumer cards (and hopefully laptops, as well).

    I had to, one more friggin time, revert back to 9.12 hotfix because the darned mouse cursor bug is back.

    Why the hell can't they get this straight? Geez.

    Sorry if this is off-topic, but it seems like a place I might get soem help on this:

    Having recently returned to AMD with the purchase of a HD5770 I'm having problems with the latest drivers, specifically they just don't seem to (properly) recognise my Panasonic V series LCD. The result is there is no DVI or HDMI (have tried both) Item added to the root tree menu in CCC. This means that amoungst other things, I can't alter the scaling -which by default results in a desktop screen that is significantly shrunk in the middle of my display.

    Luckily for me I also own a Samsung LCD. CCC recognises the Samsung and I get the DVI tree menu, which then allows me to adjust the scaling to zero. This setting is "remembered" when I plug back into my Panasonic -but what a headache, and I assume I'll need to do this everytime I update to a new ccc/driverset.

    So is this a fault with the Panny and the EDID data it sends, or is this an issue with ATI's software? The ting is I tried a much older rig running a HD3850 AGP and 8.9 drivers, and they seemed to detect the TV fine.

  • Quidam67 - Friday, February 19, 2010 - link

    For what it is worth, the 10.2 drivers seem to have fixed the problem I referred to above. I know get a menu item titled +DVT(DVI)4 in ccc giving me the scaling options back again.
    Thank god for that. I can only assume that between driver releases 9 thru 10.1 they broke something

    Last year I came up with a joke about this subject. Hope you like it.

    How is ATI like a VW commercial?

    They're both "drivers wanted".
  • Roland00 - Wednesday, February 17, 2010 - link

    Does this mean you can use 3 monitors without buying a Displayport monitor and an active adapter? For if you have 4 cards you will have 4 TMDS signal generators.
  • Roland00 - Wednesday, February 17, 2010 - link

    Meant to say 2 cards with 4 TMDS signal generators
