Hey guys, I know I need to do more tests here but just wondering if anyone has had similar issues.

My desktop has the following: Displayport and VGA

Samsung UHD (Model Number: LU28E590DS/ZA) monitor: HDMI and Displayport

Issue: When I connect the monitor to the desktop using the Displayport cable, the monitor is detected but nothing displays. I have plugged in a second monitor using VGA and can see that the monitor is picked up. I have tried adjusting (loweing) the resolution but still no go.

When I connect the monitor to my laptop using HDMI, it works fine.

So yea, I don't know if it's the Displayport port on the desktop/monitor or whether it's something else. Does the fact that the monitor is detected mean that it isn't the port? I have tried a couple of Displayport cables. I have also checked for drivers on my machine but the drivers just show Intel HD graphics so not exactly sure what video drivers I need. The Intel update app doesn't show any updates available though. Any ideas? Thanks.

The display manual suggests the following:-

- Do not connect the power cable before connecting all other cables.

- Change the input source to DisplayPort controlling the JOG button UP/DOWN, when input source
is not set.

- To display 3840 x 2160 at 60 Hz, use a DP cable that supports 3840 x 2160 at 60 Hz.
Make sure that the graphics card of the DP source supports 3840 x 2160 at 60 Hz.

Have you tried a really low resolution like 800x600?

Thanks. Yea tried all that. Finally got it going with a third DisplayPort cable. Strange because the other two worked fine with another machine. Bizzare. But happy that it's working! Thanks.

And it went blank again after a restart. Sigh.

Might be something to do with the graphics card/resolution? I have set the resolution to 1920x1080 but it's still not working. However, just testing with another laptop now and it's working perfectly fine at any resolution up to 3840x2160. With my desktop, I don't see that option (max is 2560x1440 I think). Anyway, it worked once or twice but hasn't worked since (with my desktop).

Sorry if my info is all over the place. Finding it strange that it worked randomly a couple of times and then stopped working.

The other bummer is that my desktop is a ultra small form factor machine with no pci express slot so I can't upgrade the video card even if I have to. Hmm..

Not that tech savvy so any advice would be awesome. Thanks.
