Re: ThinkPad P51 - Screen brightness always at maximum in Discrete Graphics mode

Thank you! The Adobe result is just what I need .... brightness - not such a big deal. Now I'm really looking forward to getting the machine (any day now!)

Any tips on calibration? I assume you have the built in Calibration tool - although I'm sure that the Spider Pro is much more accurate.

Checked your other posts and saw the pics!

The inbuilt sensor is really useless. It doesn´t calibrate the display, it miscalibrates it. The Spyder is much better for sure.

Regarding the brightness problem, I heard that nVIDIA has a new driver version (.8229) which is currently in testing, it fixes the brightness issue.  I don't have a timeline for when it will be released, but I just wanted to let you know that the fix is coming.

This worked for me as well. Hopefully they will get the new driver working soon.

 

EDIT: Windows keeps updating the driver to 8205, breaking screen brightness again...any ideas on how to lock it down to the one that works for now?

If you use the "Roll Back Driver" button in Device Manager, Windows is supposed to leave the driver alone until such time a newer version (newer than the one you rolled back) is posted to Windows Update.

Thanks, I did do that and it seems to be okay for now. Any ETA on the updated driver?

Maximum screen brightness  in Discrete Graphics mode 75% (brightness on 100% is the same how 75%, It is not changing from 75% to 100%. From 0% to 75% is changing). Brightness is worse than the 5.5 year old T520.  I installed clean windows, all the possible drivers, trying to change the settings ... nothing

Normal behavior apparently with this screen. So everything is working as expected, as long as you can change brightness at all. My problem was the brightness was always stuckat 100 %.
