Re:X1C 6th Gen - Lenovo revoking support for 5120x1440 ultra-wide

2020-04-24, 4:20 AM

So although I posted few days ago that everything was working, today my PC forced a update on Windows (took me over an hour to install) to Version 1909 (OS Build 18363.778).

 

This created a major problem for me, since it updated the UHD620 driver, and it lost the option to "rollback driver", and of course the 5120 x 1440 was gone.

 

 

If you are in the same boat, don't panic.  I had it fixed.

Here is what I did

 

  1. First get the UHD driver that works.  Mine is 26.20.100.6709, but I forgot where I got it from.  The installer file name is dch_igcc_win64_26.20.100.6709.zip so Google it.
  2. Also get the Intel Graphics Command Center and install it  https://www.microsoft.com/en-us/p/intel-graphics-command-center/9plfnlnt3g5g#activetab=pivot:overviewtab
  3. Go to your Device Manager, and select the UHD 620, then select "Uninstall device".
  4. Uninstalling the device will make the display look ugly, but don't worry
  5. Restart your computer here
  6. Once restart, open the device manager, and look for Unknown Device, which should be the UHD620
  7. Then select "install driver" and make sure you choose the driver you downloaded on step 1
  8. Once this is done, you might want to restart again,  
  9. After restart, your display should be looking just fine.
  10. Launch the Intel Graphics Command Center, and then hopefully you will see the option for 5120 x 1440

 

Hope this works for all of you. I am using the LG 49 display.  

 

 

I hope the May 20 major Win10 update will not affect this... let's see.

BTW, my BIOS is LENOVO N23ET71W (1.46)

Re:X1C 6th Gen - Lenovo revoking support for 5120x1440 ultra-wide

Hi there!

 

I have an X1 Carbon 7th Gen (Fall 2019) with an Intel Core i7-10710U CPU -> https://www.intel.com/content/www/us/en/products/processors/core/i7-processors/i7-10710u.html

I recently bought the Samsung CRG90 (C49RG90), a 49" 5120x1440 ultra-widescreen monitor. 

 

When I plugged it in via HDMI using the included HDMI 2.1 cable, my max resolution was 3840x1080. I found this post and did the following:

  1. Download and install Intel® Driver & Support Assistant-> https://www.intel.com/content/www/us/en/support/detect.html and Intel Graphics Command Center -> https://www.microsoft.com/en-us/p/intel-graphics-command-center/9plfnlnt3g5g. Run both, but do not install any drivers yet.
  2. Uninstall current display device driver (Device Manager > Display Adapter > Intel UHD Graphics > right click, select properties > (new window) > Driver tab, select uninstall device > check "Remove all from system" (this last part is important, per intel's site -> https://downloadcenter.intel.com/download/29530/Intel-Graphics-Windows-10-DCH-Drivers?product=80939)
  3. Restart
  4. Now go back to step 1, run the Intel Driver & Support scan, and install the drivers.
  5. Restart again
  6. Now go back to step 1, in the Command Center you should be able to unlock the 5120x1440 resolution.

 

One update to this from the next day: When I came back to my pc the resolution was all messed up. The display driver was the same one I installed the night before. I fixed this by following steps 2->6. I hope I don't have to do this every morning...

 

EDIT: This happens each time the computer falls asleep now, which is a pain. But, all I must do now is Step #2 above and then my resolution goes back to 5120x1440. So, something with Lenovo keeps happening and this undoes it.

Any updates on this? None of the fixes in this thread (or the other) work for me.

 

I have a T490 and I've tried both BIOS 1.61 and 1.65 (latest). I've also tried Intel UHD 620 drivers 25.20.100.6581, 26.20.100.6860 (From Lenovo System Update) and 26.20.100.8141 (from Intel Driver & Support Assistant).

 

No matter what, I get a max resolution of 3840x1080.

 

Has Lenovo commented on this matter? I read that some of you guys have had open support tickets regarding this issue.

Hi all,

 

I just got this message from Lenovo Support:

 

It's correct that the Intel HD 620 does not support any 5120-displays, so even though the Pixel-amount is less than the max resolution, this is not supported. This is a limitation from Intel, and Lenovo has updated to the Intel specs. We are aware that an earlier driver had this working by mistake, but the supported solution is that it's not working. 

 

 

So basically, if you bought a 5120x1440 display for your Intel HD 620 laptop, sucks to be you. It used to work "by mistake" (what does this even mean), but has since been "fixed" to no longer work.

 

Great job, Intel/Lenovo!

Re:X1C 6th Gen - Lenovo revoking support for 5120x1440 ultra-wide

I've been battling this issue since the beginning of the year. I am livid that Lenovo would promote and sell 5120x1440 support on the X1C 6th Gen "by mistake".

 

I've been rolling back every graphics update since this first happened, until this morning. The rollback option was grayed out, and when I tried to install the version that I knew supported 5120x1440 I kept getting the "you already have the most recent version of this driver" notification. I don't know why this happened as I uninstalled all the Intel drivers, leaving me with just the basic Microsoft driver.

 

At this point, I eventually went on Intel's website and downloaded their 'Driver & Support Assistant' tool so that it could identify the most recent, non-Lenovo driver that would work for the X1C 6th Gen. It installed 27.20.100.8190 (driver date: May 5, 2020) and I'm back to 5120x1440 on my Dell U4919DW (via USB-C)!

 

EDIT: Forgot to add that, at least in my case, 5120x1440 continues to work despite the computer going to sleep, being restarted, or shut down.

I'd like to buy a u4919dw to use with a T590/UHD620. Any issues since switching to intel's driver earlier today? (what a coincidence!)

Fortunately, no issues yet; however, I doubt that it'll stay issue-free. For all I/we know, the next driver update could lead to more 5120x1440 issues.

Yeah, I hear that. I don't want any callbacks on this issue, and the u3818dw is working fine. Bummer, thanks!
