Just to add a bit of context and why this is an important fix: this is a $340 39" 3840x2160 @ 30hz (100 DPI) monitor. All the X developers should be running this. At $340 it is cheaper than a lot of crappy monitors of much smaller size both physically and pixel-wise. Given the incorrect dot-clock checking in X, the refresh is limited to around 13 hz. That sucks. Oh, yea, and a buddy that runs that OS from Redmond says it works at 3840x2160 @ 30hz for him with no futzing around needed. Have you considered testing a later Xserver? In particular, 4k support requires commit d6c8d7509727060b8e2358b9ed1c0e17b2ec3401 Author: Damien Lespiau <damien.lespiau@intel.com> Date: Wed Jul 31 19:16:45 2013 +0100 xfree86: Use the TMDS maximum frequency to prune modes Instead of only relying on the Range section, we can do better on HDMI to find out what is the max dot clock the monitor supports. The HDMI CEA vendor block adds a TMDS max freq we can use.

(In reply to comment #6) > You GPU does not support 4k over HDMI. I assume this was meant for someone else. My GPU is the Radeon 6450 (card: Sapphire Radeon HD 6450 1 GB DDR3 HDMI/DVI-D/VGA PCI-Express Graphics Card 100322L) The specs at AMD claim this GPU does HDMI 1.4a 2 lanes of 340 Mhz dot clock each for a total of 640 Mhz. Even if only one lane is populated on this card, that should still be 340 Mhz. The modeline only asks for 297 Mhz. As for the framebuffer size, xrandr claims this card does a 16k x 16k virtual buffer. That too is enough for the 3840 x 2160 screen. In fact the card works just fine at 15hz (as evidenced below). In fact I'm typing this bug report at 3840x2160@15.00.

I think you've been successfully fooled by the HDMI forum, which allows anyone to implement some boring subfeatures noone is interested in and leave out the only thing important, namely higher frequencies, and still claiming newer standards (1.4 in this case) compliance regardless (for receiver devices which don't have such a high resolution this actually even makes sense). But don't worry AMD isn't the only one with "hdmi 1.4" and not supporting higher frequencies. In fact AMD clearly states max resolution over hdmi is 1920x1200. http://www.amd.com/en-gb/products/graphics/desktop/6000/6450# unless you've found some other doc... And yes low refresh rates are always a way around that, I think it's typically not mentioned because it may not work (some monitors really might not like it).

The spec sheet at the URL you quote below mentions HDMI 1.4a. Although I can see how they might be skirting the truth about HDMI 1.4 compliance. Are there any GPU's and/or cards that are known to display 4k at 30hz or above under X? (In reply to comment #9) > Are there any GPU's and/or cards that are known to display 4k at 30hz or > above under X? Your card is DCE5 which supports 4k over displayport only. DCE6 and newer (SI family and newer; Radeon HD 7xxx and newer in marking parlance) support 4k over HDMI.

Although I > can see how they might be skirting the truth about HDMI 1.4 compliance. 1.4a only added some 3d formats (frame packing), but only with resolutions which you can do with "old" frequencies (1080p24 x2 and similar). hdmi 1.3 (!) was actually the new version which introduced the higher frequencies, though I think devices claiming to only be hdmi 1.3 compliant actually supporting the higher frequencies were very, very rare (if they even exist). It is possible supporting these was mandatory with 1.4b (cause it introduced 1080p60 x2) but I wouldn't bet on it neither. Similarly, there's now "HDMI 2.0" devices out there which only support 4k with 30Hz and not 60Hz (or more specifically, 340Mhz frequency instead of 600Mhz). All the same old story.

I got a Radeon HD 7770 card and it comes up at 3840x2160 @ 30.00 hz, which is all the Seiki 4k display will do. As mentioned in comment 12, the error "(WW) EDID timing clock 297.00 exceeds claimed max 115MHz, fixing" is still logged, but the card does get configured with the 297 Mhz dot-clock, because it does display 4k at 30hz (according to the on-screen data displayed by the Seiki monitor.)

I too have this monitor. I too get "(WW) EDID timing clock 297.00 exceeds claimed max 115MHz, fixing" I'm running "X.Org X Server 1.14.4" that is the latest version with Fedora 20. I have no idea if the Intel video can handle 3840x2160@30Hz. The processor is Intel(R) Celeron(R) CPU 857. But nothing in the Xorg.0.log seems like a complaint from the intel driver (i.e prefixed with "intel(0)"). PS: Hi, Wolfgang. Our paths cross in another bz entry. Even if this isn't a bug, I suggest the message I got be changed to indicate the source of the claimed maximum 115MHz -- I have no idea where that limit comes from. Also, if a driver trims modelines because of limitations, surely it should log that fact. -- GitLab Migration Automatic Message -- This bug has been migrated to freedesktop.org's GitLab instance and has been closed from further activity.
