the display of my T510 (typ 4337) chnages the brightness and contrast itself while in dockingstation. The contrast gets very low so that neither backround nor icons are clearly visible.The only thing that helps in this situation is a reboot of the system.
Sometimes it happens twice a day in other times only once a week. Since I have to work with my T510 its annoying to shot down the system in the middle of day.
I updated the video driver as in other post recommended:
After that please restart the system and check whether the issue has been resolved.
Thanks & Regards,
