New drivers for the X1EG2, for both Intel and NVIDIA graphics.

 

None of them fixes the issue.

 

I gave up, don't have any expectations that this will be fixed one day, and I assumed that Lenovo removed intentionally 20% of brightness from our displays. At least my paltry battery life will be a bit "better" due to this issue.

 

Never again Lenovo.

Re:Latest Intel Graphics Driver Makes Display Dim

I got back my old Dell XPS to work on, trusty keyboard and display working as expected. Feeling more comfortable.

I'm deeply and badly impressed by Lenovo behaviour, quite schocked. It has no sense at all. 

To release a new driver (the second time, after 7811) following one hundreds pages of compliants, without testing it. Well done.

 

WHERE IS THE PROBLEM HERE?

 

Dear Lenovo, pick up an X1EG2 from your own warehouse, replicate the issue, then fix it and TEST the solution. Your customers are not in charge to test it for you.

Your customers bought a pc based on their own needs and requirements vs the tech specification you provided, and paid cash for that, against your competitors. 

 

Now getting quite. Is out there any specific procedure to install the driver, since the first *7811 Intel Graphic driver was pushed by windows update as a DCH driver?

Do you suggest to clean uninstall by the Intel DDU?

Or just run Vantage to update?

The new driver released a few days back raises the max brightness a little bit on my 500 nits FHD. It was like 300 nits but now it's probably 350-400. Still, it's no way close to the claimed 500 nits. The fact that Lenovo doesn't even bother to reply a thread with over 100 replies really sickens me.

from the release notes:

CHANGES IN THIS RELEASE  Version  27.20.100.8190  [Problem fixes] - Fixed an issue wherein intermittent blinking might be observed on AUO UHD Panels   when HDR was on.

...so AUO uhd panel specific.

My expectations for a full patch are null.

Lenovo is just closing a trouble ticket dedicated to a well defined panel. Can't understand how a priority level is assigned to an issue. 

May be X1EG3 being on the launch ramp.

Hello,

 

Have you tried installing the KB4568831 (July 31, 2020) Windows 10 update?  According to https://support.microsoft.com/en-us/help/4568831/windows-10-update-kb4568831, it fixes an issue with HDR content appearing darker than it should on the screen.  Also, Intel released graphics driver version 27.20.100.8476, which can be downloaded from https://downloadcenter.intel.com/download/29784/Intel-Graphics-Windows-10-DCH-Drivers?product=80939.  It also contains issues with screen brightness changing when playing HDR content on the screen as well, according to its release notes.

 

Regards,

Tested Intel driver 27.20.100.8476 doesn't work neither. 

 

I believe this is not a software issue, this is a hardware issue related with BOE panel PWM brightness adjustness circuit.  These circuit arrangements will not work under new Intel graphic framework. So Lenovo newest driver update fixed some of the 4k laptops but most laptops with BOE 4k panels are not yet fixed.

 

I believe Lenovo already knew this, so they just closed the case and quit further updating video driver.

Please consider that, on the X1EG2, disabling integrated graphics on BIOS 'fixes' the issue.

 

Also, it improves graphics performance on desktop, but reduces battery life and possibly has an impact on the device longevity because of use of dGPU.

 

I don't expect this problem to be resolved, sadly.

@joloriquelme Just wondering- is there a brightness difference between discrete-only graphics and the .7529 driver on hybrid graphics?
