Laptop: Lenovo Y510P, Dual Nvidia 755M 2GB, 16G RAM, Core i7 based.
Monitor: ASUS 24 inch Model VS248H-P ([url:192hnug4]http://www.asus.com/us/Monitors_Projectors/VS248HP/[/url:192hnug4]).
Using NVIDIA drivers: 334.21
Running KDE. When I connect the monitor to the HDMI port, I immediately get a popup about a mew monitor detected and if I would like to try to automatially configure it. Before even answering the question the monitor is on and I get the mirrored screen - image looks good. nice and crisp. But within a few seconds, starts to cycle ON and OFF.
It auto detects the following:
Size: 1920x1080 (Auto)
Orientation: No Rotation
Position: Absolute 0 0
I set DP-0 (connected) [Laptop Screen] to be position Left of HDMI-0.
Primary output: DP-0
Then HDMI-0 screen keeps turning ON and OFF. Appears to be random, but also appear to be ON less and OFF more each time but not always. It appears to be video signal / sync issue. The LED light on the front of the monitor is not turning ON and OFF. When it comes back on it show the “HDMI Video” overlay logo the monitor adds to show which connector is used. This is a 76hz monitor, but the drop down doesn’t let me pick anything higher than 60. I tried several different refresh options from the drop down, they all seem to do the same.
If I pick a selection lower than 1920x1080 such as 1600x1200 - the screen stays ON. But obviosuly I want it to work at full 1080P mode. I also see what can best be described as green static in a few locations around images such as around letters in images where you get pixelation. When I drag the window around, even slowly the green static goes away. Comes back when I release the mouse button. When I switch back to 1920x1080 there is no green static, but it goes back to cycling.
I’ve never had a problem connecting HDMI monitor before, so not sure what information would be useful here. I don’t see anything obvious with DMESG.
I can use the monitor at 1080p with two other laptops. One running Antergos / cinnamon and the other running Windows 7.
