GFX 4678 driver cause black screen flicker offen in 4k 60hz mode

Dear all

I have a 4k monitor runs at 4k 60hz, and occasionally I got HDMI output lost in standby mode. I have updated the GFX driver to latest .4678, and HDMI firmware to 1.66. but no HDMI lost are solved and I have got many black screen flickers when playback 4k videos and photos. Sometime even in web browsers.

Do some other one have similar problems? I am doubt it may be a driver bug.

Thanks and regards

I am sorry for the inconvenience. I would recommend to keep working on the original thread /message/479752# 479752 where you reported the issue after updating the graphics driver.

Best Regards,
