GTX 980 incapable of 2880x1620 or higher? Or bad card?

    I use these settings with my 580.

    I get a black screen and white line at the top like MrBonk when I try it with my 980, the HDMI cable and monitor are the same.

    3840 × 2160 works with DSR btw.

    Automatic timings give the same result :(

    And DSR has 0 problems. I can use 3200x1800 DSR without issue.

    I've got a cable ordered with 2 day shipping should be here Friday. Hopefully it makes a difference. If not..

    DVI-D Dual Link Cable came in. NOPE. Same problem.

    Hi !

    From what I see I'd say that's just a values issue. You should set 910 vertical active pixels and try to find the right horizontal active pixels that'll work. Try this and add +100 increments to find the range where you get something on display. You can lower the refresh rate to make it easier to find the right spot.

    That did the trick kinda sorta. Thanks.

    Couple of problems.
    http://i.minus.com/i0luTIu7emc5W.jpg
    1. I have to set not just the total pixels column but the base as well.
    2. For horizontal I have to have a +200 offset at the bottom (And anything less than 2000 doesn't work.)
    3.This results in ugly scaling and a blurry picture rather than an over sharp one as it should be. Ex: 2720x1530 works without issue displays correct scaling. Using the settings above for 2880x1620 results in same bad scaling and is blurry.
    4.When set to "Aspect Ratio" the GPU detects the resolution/aspect ratio improperly. So the picture will be squished (Black bars as you'd mention), but if you take a screenshot it will be fine.
    5. Games will not detect these resolutions because they aren't being detected by the proper aspect ratios. If an application has a custom option and you set the resolution. It will default and switch to the next closest properly detected resolution. (Which in my case is 2720x1530)


    Man, I just don't get how this massively more powerful card has such problems doing what a 570 could do with 0 problems.

    I feel like giving up now almost. Can't quite win. I guess I mean if we could set DSR resolutions ourselves by simply specifying any given resolution. Wouldn't need this anyway haha....

    Oh, sorry I mixed things up...
    I meant total pixels not active pixels :wanker:
    Keep 1600x900 active, set 1800x910 total and try different values as horizontal.

    Yeah I knew what you meant. But nothing I was trying was working (I used values all the way up to 2800 until it started saying unsuported )so I did what I mentioned before

    This is the point where I stop getting the line on the top

    Couldn't run 120hz on cheap dual link dvi.
    Purchased a solid awg one from monoprice. 15ft to boot! (pc a distance from monitor)

    Possibly ****e cable? Possible to return the card?

    Honestly I think you are blowing this way out of proportion :)
    More than 4xDSR is too much in most games for a single 980 anyway.

    Combine that with TXAA or other settings, and you should be good to go ;)
    And who knows, maybe we will see higher DSR levels in future drivers.

    This is the cable. I have several others by BlueRigger, love'em.

    I was able to get 2880x1620 to work with a derivative of this after using the pixel clock patcher :) So that's progress.

    The most I can get out of 32x18 is a few lines at top and the rest is turquoise and flashing haha.

    Thanks for the help!

    Too much for some modern games performance wise? Sure.

    But not all games I play are current releases. I've got quite a big backlog, several hundred hah.


    But what I was referring to rather than going above 4xDSR was being able to just set the resolution I want to scale with DSR and be done with driver downsampling for good.

    (Ex 32x18 on this monitor usually is my limit +other AA. But I often use lower integer multiple resolutions too, like 1.2x1.2,1.5x1.5,1.6x1.6,1.8x1.8,etc. And DSR is stupid in that it calculates resolutions you can use based on the final % number of the multiples. This is why we have silly options like 110% 300% and so on. Almost all of these require either rounding or a lot more decimal places instead of keeping it simple with 1.X)

    In some cases for some games a certain aspect ratio has to be used, so I use one of those. (Eg: Castlevania Mirror of Fate, King's Bounty Games, some 4:3 games,etc)

    I see, didn't really think of that :)
    Normally I just use 4xDSR at 1920x1200 (3840x2400) and be done with it (in DX11 titles at least).

    But in special cases, where you need to run at a certain "unusual" aspect ratio or resolution this can be a problem.

    My cards have doubled display clocks so it probably explains why it works for me not for you. You may have to go higher with the values.

    Doubled display clocks? The front porch/sync stuff? Or the GPU clock itself?

    Would it really make a difference I wonder?

    As far as the card goes, I suppose I could RMA it, I mean. My 570 isn't good for long term use due to the damage, but like I mentioned earlier downsampling is no problem even with a generic single link cable :|

    I'm contemplating the RMA at the moment because, aside from 3200x1800. All of my other resolutions are working.

    And i've got a somewhat decent stable overclock so far (1506 on core, ~7900 on the memory on stock volts. This has been flashed to bake in the clocks and make sure the voltage doesn't drop either. However i can easily reflash the stock BIOS if I RMA)

    nope it's cable limitation and/or monitor limitation.

    Yet i've posted that it was just dandy with an older GPU.

    I checked again today when I was testing something else on the 570.
