Works in windows doesn’t in linux. Windows screenshot:

Linux always said 165 Mhz limit but even forcing it with:

Option “ConnectedMonitor” “HDMI-0”
Option “UseEDID” “False”
Option “ExactModeTimingsDVI” “True”
Option “NoBandWidthTest” “true”
Option “ModeValidation” “AllowNon60hzmodesDFPModes, NoEDIDDFPMaxSizeCheck, NoVertRefreshCheck, NoHorizSyncCheck, NoDFPNativeResolutionCheck, NoMaxSizeCheck, NoMaxPClkCheck, NoEDIDModes”

This modeline works:

Modeline “3840x2160” 165.00 3840 4080 4488 5136 2160 2163 2168 2199 -hsync +vsync

This one does not:
Modeline “3840x2160” 165.01 3840 4080 4488 5136 2160 2163 2168 2199 -hsync +vsync

The modeline I want to run:

Modeline “3840x2160” 296.70 3840 4016 4104 4400 2160 2168 2178 2250 +hsync +vsync

Please fix. Don’t make a custom who has used your products for 12+ years switch to ATI because of this.

Just on the off-chance this was due to weird issues running off a laptop (I have had a laptop in the past that thought it was dual link DVI when it wasnt) or the gtx 470 i had was too old for HDMI 1.4 I picked up a gtx 670 and I am having the same issue (No surprise there).

Here is my Xorg log file:

[url]http://box.houkouonchi.jp/Xorg.4.log[/url]

I also tried the newest beta drivers (319.12) and no change.

Can you describe the problem in more detail? According to your log file, the 296.70 MHz mode was validated and is being used:

Well keep in mind that is forcing it.

Why does the HDMI say 165 Mhz single link TMDS? That is wrong. HDMI 1.4 should be 340Mhz not 165:

Funny coincidence that as soon as it goes > 165 Mhz (165.00 → 165.01) it breaks. It says the mode is valid but it does not output to the display at all. Its not even just a case of bad output because if that was the case the display says ‘not supported’ but its just ‘no signal.’

I agree the driver is using the modeline. The problem is the hardware is not outputing the signal. No modelines over 165Mhz work over HDMI at any resolution). Obviously the driver has something hard-coded in it to not output over a set limit which was correct back with the HDMI 1.0/1.1/1.2 standards.

With HDMI 1.3/1.4 it should be a 330Mhz sealing. Again this works on windows but not linux even when giving it the exact same timings.

FYI DVI does the same exact thing if you try to go over 400Mhz pixel clock (which works on windows) but as soon as you go to 400.01 Mhz the video card doesn’t output anything at all.

5

That 165 MHz limit is reported by the hardware, but NoMaxPClkCheck should be overriding it. However, I found what looks like a bug that could be causing this problem. I’ll try to track down a similar display so I can check.

6

Well I guess the question is why does the hardware report 165Mhz maximum when you are trying to push ~300Mhz over it?

Is the code for HDMI basically the same as DVI? Because I know with DVI as soon as you go > 165 Mhz it does dual-link mode and completely changes the type of output its sending out. HDMI is not like that it is supposed to do 330Mhz with a single TMDS link. That might be part of the problem?

Honestly you could probably re-produce the issue even on a display without HDMI 1.4 spec (as I know those are incredibly hard to come by). Just try getting 1920x1080 (or 1920x1200) going over HDMI with a modeline at 165.00 Mhz (exactly) at 60-ish Hz. Then increase it to 165.01 and watch it break.

Like I said DVI does the same thing @ 400Mhz. Fixing that would be nice too but thats technically over regular DVI spec so I am not gonna bitch about that here. That HDMI port should be capable of doing what I am trying to do. Its within spec.

Oh and nevermind the 400Mhz DVI thing is different I guess it is actually rejecting the mode:

Again though, different issue. Just mentioning it.

Woot! Good news!

So today I stopped by newegg to pickup this adapter:

My testing with active single-link adapters brought me to the conclusion it could get around the nvidia driver limitations as it uses DFP-4 (display port with its 960Mhz bandwidth limit) instead of DFP-1/HDMI-1 which says 165 Mhz max as the active adapters actively convert the DFP LVDS to TMDS.

Up to 27Hz on linux. I bought an active DP → HDMI adapter and it will do up to 238.50 MHz (doesnt work @ 238.90 Mhz) which upped my limits.

At 238.90 Mhz I get:

(II) Apr 26 14:29:53 NVIDIA(GPU-0):   Validating Mode "3840x2160":
(II) Apr 26 14:29:53 NVIDIA(GPU-0):     3840 x 2160 @ 27 Hz

(WW) Apr 26 14:29:53 NVIDIA(GPU-0):     mode timings.

I now was able to do:

3840x2160 @ 26.8 hz (ths is so much better than the 18.6 Hz I had before)
1920x1080 @ 103.2 Hz
1280x720 @ 192.3Hz

This also means now I can game @ 1080p with high responsiveness not just 720p which is also a big improvement.

Also this could be just my imagination but it seems like I am getting less banding in colors (almost like its 10 bit now). Again could just be my imagination.

Now if only I could find an active DP → HDMI 1.4 adapter. They don’t seem to be sold anywhere as far as I can see.

Nvidia definitely still needs to fix their drivers though. I am still only about to use 240 Mhz when the display takes around 300 Mhz for its full glory.

Interesting workaround with that adapter, thanks for the update. I guess I’m confused though – I thought that the monitor you were testing with only had an HDMI input, yet it seems you’re able to drive it via DVI as well?

Edit: I see that monitor has multiple (3) HDMI inputs, but I don’t see a DVI input anywhere – I’m assuming this is just bad wording on their OSD. I’ve also noticed that this particular display (SE50IY04) is very cheap! I’m amazed… < $1400

What system did you use to do the modetests? Are those from GTX 470 / GTX 670 or does the macbook pro retina work at those modes as well?

If I am reading [url]DisplayPort - Wikipedia right, it seems that whenever the new “DisplayPort Dual-Mode Standard version 1.1” actually gets integrated into the new generation of video cards, a passive adapter alone should be enough to drive that monitor natively over HDMI. For that matter, have you tried a passive adapter now? Curious if an active adapter actually makes a difference given what Wikipedia mentions.

10

I believe at lower <165 Mhz modes and lower resolutions it says DVI because its a VGA resolution (not a standard HDTV modeline) so it says DVI1/2/3 instead of HDMI1/2/3. It really depends on what signal its getting. This is not the first TV I have seen do this. It makes sense as sending < 165 Mhz is a single link TMDS which is the exact same signal as DVI if it doesn’t have sound.

When testing on windows I have only used my macbook pro retina to get the full refresh rate so I know it has the hardware to drive the display. I was able to do ~18Hz on linux on the retina as well through its native HDMI port. I did not try the active DP → HDMI adapter on the macbook yet but I would think it would work the same.

Most of my testing on my desktop has been on the GTX 670. The GTX 470 I had also limited me to ~18Hz due to not being able to go above 165 Mhz pixel clock. Of course no DP port on the gtx470 so haven’t been able to get any more out of it.

Passive adapters are no good. The problem is passive adapters are just pass-through (they don’t actually do any conversion) so they run into the same limitation/bug as the onboard HDMI port on the vid-card and die as soon as I do > 165 Mhz. That is why I had to use an active HDMI adapter but I have yet to find one that can do full HDMI 1.4 bandwidth yet (the one i have now is between full HDMI 1.3/1.4 and hdmi 1/1.1/1.2.

Hi,

Any progress on this bug. I am seeing precisely the same behavior.

Fedora 18, driver version 304.88 from rpmfusion repo.

In the following example xorg.conf, modeline “3840x2160_X” works (165mhz clk).
The other 3840x2160 modes do not work.

I also submitted a ticket directly with nvidia support (as I wasn’t sure this forum was the best place). They told me they found the issue and it will be fixed in the next driver release.

I just tried the new driver (NVIDIA-Linux-x86_64-319.23.run). I can confirm that it now works with the Seiki SE50UY04. I’m running 3840x2160@30hz on fedora linux.

Thanks NVIDIA!

Sigh they like seriously nerfed the drivers or something… Its like it only does these special modes completely dependent on EDID this extended timing crap?

Of course just to work at all it still needs:

Option “ModeValidation” “AllowNon60hzmodesDFPModes, NoEDIDDFPMaxSizeCheck, NoVertRefreshCheck, NoHorizSyncCheck, NoDFPNativeResolutionCheck, NoMaxSizeCheck, NoMaxPClkCheck”

(well maybe just the pclkcheck one) otherwise it gets:

Because of course it still has the wrong max pixelclock for HDMI:

Now If I just add:

Option “UseEDID” “False”

And:

Modeline “3840x2160” 296.70 3840 4016 4104 4400 2160 2168 2178 2250 +hsync +vsync

And AllowNonEdidModes to mode validation.

(which is the exact mode that EDID advertises) it doesnt work. Monitor doesn’t display anything.

Using the exact same modeline changing to 165 Mhz works. Changing to 165.01 Mhz and it doesn’t work… wtf? Why does it need to read EDID to do these modes?

The mode is validated.

And sadly my desktop machien (which I actually use this display on) doesn’t work because its not reading the EDID correctly off the display. And the new drivers don’t work at 24 Hz with my display port adapter either:

So what happens when people want to run custom modes or there is a problem with EDID. Why oh why would you make doing > 165 Mhz completely dependent on EDID? WHY NVIDIA?

So disappointed after waiting weeks for this fix and its still broken =(.

16

Fixed using a different HDMI port on the display and I think HDMI info is being read now. When I even provided HDMI info via a dump from my laptop it still didn’t work. Requiring modes > 165 Mhz to be in EDID is horrible. Its going to make doing custom modes (like 1080p @120Hz) a huge pain in the ass.

Very disappointed…

17

Ok not as bad as I originally thought. It still appears dependent on being able to read monitor EDID to use > 165Mhz (even with EDID given as a file) though. If EDID is read ok it looks like the monitor works as expected.

18

Ok. I used info from this forum to get it working.
EVGA GeForce GTX 680 FTW 4096MB GDDR5
Fedora core 18.
NVIDIA-Linux-x86_64-319.23.run
Check your cord! Try different ports!

I could get it to run the 30hz at full resolution but screen content was black. After better cord and different port it works fine.

We tried yesterday to get a Samsung UE55F9000 to work in 3840x2160 (24, 25, 30 Hz) over HDMI, using a Titan. Under windows, with driver 331.65, this worked straight away. Under linux (on the same hardware), driver 331.20, we could not get it to work, even with explicitly setting the modelines and applying all the options not to check pixel clock, not to use EDID settings, etc. In the log output we could see the UHD modes were definitely validated, but it seemed the X startup froze (copious amounts of NVRM Xid lines in dmesg). Unfortunately, this was in a store an hour’s drive away, and I forgot to get an nvidia-bug-report dump.

What are the chances that when a newer driver for Linux is released (>= 331.65) this will have been fixed? How come there’s such a difference in behaviour between Linux and Windows?
