Intel HD Graphics 520 refuses to output 4K... sometimes.

CMild — Sun, 17 Sep 2017 19:46:38 GMT

Short Description:

I'm connecting my laptop to a 4K display via HDMI. Some of the time, it works fine, but other times, the graphics card/driver defaults to sending 1080p to the monitor, and doesn't display the options for higher resolutions. Does anyone know why this would happen or how to fix it? (Relevant system and monitor specs are included at the end of this message.)

Detailed Description:

As I said, sometimes it works fine, but sometimes I'll plug the monitor in and the graphics card will only send 1080p. When the issue is occurring and I look at the Intel HD Graphics Control Panel, I can see that the driver still knows the maximum resolution of the monitor:

but this resolution doesn't appear as an option in the settings drop-down, either within the Intel Control Panel:

...or in the Windows Control Panel:

When I view the monitor's properties under "Devices" in Windows and "List All Modes", Windows does not seem to know that the monitor is capable of 4K:

I tried setting a custom resolution of 4K for that monitor using the Intel Control Panel, which reluctantly seemed to work (it took a restart, I think), but I suffered a major RAM failure a few days later, which seemed to originate with the graphics card (the first sign of failure was the on-board screen flickering and becoming checkered before the computer became unresponsive). Because of that, I'm concerned that I could be damaging my hardware by setting a custom resolution through the Intel Control Panel, even if I'm setting a resolution that I know should work.

All my drivers are up-to-date, my HDMI 2.0 cable is able to support 4K, and I'm only using my on-board monitor or the external monitor, never both (so no cloning issues).

If this problem were always happening, then I'd try reinstalling Windows or flashing my BIOS, but the fact that it only happens some of the time makes me think that it's not the type of consistent problem that would come from issues at that level.

Does anyone have any clue how to fix this mess? I currently have a 4K monitor that I can't use, so I'd really appreciate your help. Thanks!

Computer:

Lenovo ThinkPad T460s (type 20F9-CT01WW)

OS: Windows 7 Pro (x64)

CPU: Intel core i7-6600U @ 2.60 Ghz

Graphics: Intel HD Graphics 520 (capable of outputting 4K via HDMI, specifically 3840 x 2160 30p Hz)

External Monitor:

(capable of displaying 3840 x 2160)

Hello IntegratedGraphicsFail,

I understand that sometimes the graphics card refuses to output 4K resolution.

Let me apologize for any inconvenience this issue may be causing to you.

I would like you to try completely removing the graphics driver and then reinstalling it. Please download the graphics driver that is on this link https://downloadmirror.intel.com/26836/eng/win64_154519.4678.zip https://downloadmirror.intel.com/26836/eng/win64_154519.4678.zip

As soon as the graphics driver has been downloaded on the keyboard press WinLogo key + r, then type in devmgmt.msc, double click on Display Adapters -> Intel HD Graphics -> Driver tab -> Uninstall -> Select the check box Delete the driver software for this device -> OK, restart the computer, and then reinstall the driver with the steps that are on this YouTube video https://www.youtube.com/watch?v=S1KzoQDjMMY https://www.youtube.com/watch?v=S1KzoQDjMMY

I would like you to also try installing the monitor driver. You can download it from this link http://www.lg.com/us/support/software-firmware-drivers http://www.lg.com/us/support/software-firmware-drivers

If issue persists please reply to this email attaching the .txt file the Intel® System Support Utility will generate https://downloadcenter.intel.com/download/25293/Intel-System-Support-Utility https://downloadcenter.intel.com/download/25293/Intel-System-Support-Utility

Hi Fred,

Thanks for following-up. It has been a very busy week and I haven't had a chance to try your solution. I'm hoping to do so soon, and I'll let you know what the results are. Thanks again for your help!

Hi Fred,

I tried uninstalling and reinstalling the graphics driver, but the problem has persisted. I've pasted in the output file from the Intel System Support Utility. What would you suggest? Thank you!

Hi Fred,

So, the issue didn't happen again for a little while (it's always been a somewhat intermittent problem), so I wasn't able to test if your fixes worked. The problem is now occurring again, and continues to occur even with all your fixes implemented. Additionally, I'm now also having an issue where online videos (e.g., Youtube) run at 5 or 8 FPS with no sound, and sound won't play on the machine at all (even local MP3 files) until I restart. I don't know if this new problem is associated with any of these fixes, but I suspect that it's somehow graphics related.

If you have any other solutions to my persisting resolution problem and my new video problem (which is also intermittent) I would really like to hear them! Thank you!

To help you figure out why this is still going on, here's a new dump from the SSU:

Hello IntegratedGraphicsFail,

I am sorry to hear you are still having issues with your computer.

I would like you to try installing newer version of the graphics driver. You can download it from this link https://downloadmirror.intel.com/27266/a08/win64_15600.4849.zip https://downloadmirror.intel.com/27266/a08/win64_15600.4849.zip

Let me know if issue persists or not with that graphics driver.

Regards,

Fred D.

Re: Intel HD Graphics 520 refuses to output 4K... sometimes.

CMild — Sun, 03 Dec 2017 23:42:21 GMT

I tried to install the driver that you linked to after uninstalling the existing driver. Windows couldn't install it, probably because it's the completely wrong driver (it's apparently a Windows 10 driver)!

I then spent 20 minutes trying to download a serviceable driver while viewing the internet in 640x480, because you had told me to delete the existing driver.

I'm now back to driver version 21.20.16.4550 (dated 11/11/2016), and the problem is still persisting.

Do you have any idea what's causing this? I'm getting pretty frustrated.

Thanks Fred for the response.

I've previously done just that in a different thread, titled

The information you seek is available there. If you have any difficulty accessing that information, please let me know.

Thank you so much for your help.

In addition,

I'm now getting occasional stuttering when playing 1080p videos as well (especially, though not limited to, VLC player.)

Hello IntegratedGraphicsFail,

We recently released newer version of the graphics driver and I would like you to give it a try. You can download the driver from this link https://downloadmirror.intel.com/27360/a08/win64_15.45.23.4860.zip https://downloadmirror.intel.com/27360/a08/win64_15.45.23.4860.zip

Please install the driver using the steps that are on this YouTube video https://www.youtube.com/watch?v=S1KzoQDjMMY https://www.youtube.com/watch?v=S1KzoQDjMMY

Let me know if issue persists or not.

Re: Intel HD Graphics 520 refuses to output 4K... sometimes.

CMild — Wed, 13 Dec 2017 21:06:12 GMT

Thanks for letting me know, I'll try the new driver soon.

In the meantime, could you post some written instructions on how exactly you want me to uninstall the old driver and install the new one? (That Youtube video is terrible. It's almost too small to read on my screen, has no narration, and is just generally a mess. If you want the install done a specific way, written instructions would be much clearer and easier to use.)

Thanks!
