T490S Faulty UHD620 drivers: 26.20.100.7063

Greetings!

I just installed latest Intel UHD Graphics (Windows 10 version 1709 or Later) - version 26.20.100.7063

 

I found out I have major graphical issues now due to this update.

Several programs don't render graphics properly at all:  Chrome was all black ( something I managed to get working), Powerpoint won't render images and other graphics etc.

 

I dried re-installing the driver, also checked on device management if there was rollback option but it's greyed out.

What would be the solution for getting things working again? Official T490S driver page doesn't list older drivers to try out either.

 

I did systems check on vantage and on the support page along with checking all drivers are up to date: all says okay and up to date.

 

Couple images for demonstrating issues:

I can verify that Intel UHD Graphics (Windows 10 version 1709 or Later) - version 26.20.100.7063 breaks everything on all Lenovo T490s in our company!

 

I downloaded an older version of the drivers from this link, so the machines are usable again: https://downloadcenter.intel.com/download/28991/Intel-Graphics-Windows-10-DCH-Drivers

 

go for the version called 26.20.100.7000

Re: T490S Faulty UHD620 drivers: 26.20.100.7063

Can confirm, after recent driver update have many t490s that are unable to use chrome/slack/ect. Was able to fix chrome by turning off hardware graphics acceleration (had to blindly get to the setting and turn off as the settings window is not viewable in chrome). Not able to fix Slack. Also, not able to install the rollback graphics driver linked above (igfx_win10_100.7000) as the system does not recognize it as allowable.

Help.

i searched for "uhd620 driver 2019" and got to intel download page. Then i tried the last 2, the one ending in 7000 was working.

 

It's an .exe download, you have to run it (it tkaes a while to open...)

 

you just have to make sure you uninstalled the old one (by uninstalling your video adapter, the uhd 620, windows will revert back to default video adapter (not named uhd620)

 

then you reboot, then you install the downloaded one.

 

good luck!

Hi folks

I had this very same problem and think I've resolved it. I downloaded the latest 7063 version driver from here:

   https://download.lenovo.com/pccbbs/mobiles/n2siv03w.exe

 

Then, I went to the video graphics card properties, drivers tab, and uninstalled it (I didn't tick the 'remove drivers' checkbox -- more by mistake than by design, anyway ...). Once this was complete (only took a minute), the screen resolution went to quite a low res but I was still able browse Windows Explorer to where I had downloaded the latest driver. I re-installed it and then changed the display properties back to 100% scale (it was set to 150%). Now everything seems hunky-dory again! Chrome and PowerPoint and graphics in general are rendered properly once more!

 

Hope this helps,

Tim
