Hey MSI,

I just installed my new 32" 4K 144Hz gaming monitor and I couldn't get any display port video output (regardless of settings, old 4K monitor drivers being removed, and x3 different 8K 1.4 Display Port cables, including the new one that came in the box... all have the same result.

Details:

Windows 10
MPG321UR-QD FW: .016
Display Port 1.4 version cables (all x3 different cables used)
Previous Samsung 4K monitor works on all cables / Display Port input from GPU's
Tested both GPU (SLI on individually) Display Port connections.. all work on old monitor, while none work on the new MPG321UR-QD

The only way to get any video output is to use HDMI cable that came with monitor... but I'm only able to get 60Hz refresh rate, despite changing it to "PC 144Hz" settings in OSD config

Manually select DP source on OSD, and it flashes a small window that claims that there is no connection, yet I can restore the same connection to my old 4K monitor and it works perfectly fine

Please help! -I was planning on re-gifting my old 4K Samsung monitor to my niece, but I can't do that, until I'm up and running on this new monitor

Thanks,

Eben

UPDATE: I am able to get the display to recognize an HDMI input (only at 60Hz, regardless of cable or settings), but the monitor will frequently have the video drop out to a black screen, at random intervals (only to come back *sometimes* after a few seconds... this is not the PC going to sleep, or screensaver modes as I have disabled these features for troubleshooting). -I'm now looking to return this brand new unit as defective, back to Newegg... too bad, as I was really looking forward to 4k @ 144Hz

For 144Hz, please install extra NVIDIA or AMD graphic card first on desktop system.
For NVIDIA, please install GTX 10xx or latest.
For AMD, please install RX500 or latest.

Please provide brand and model for extra graphic card on desktop system.

Please press navi key at back side to right and then choose input source as attachment.

Fauc,

Thanks for the reply.. Unfortunately, I am only able to run x2 GPU's (in SLI or individually) on my MSI MEG Z490 Unify MoBo. I currently have x2 EVGA 1070's installed.

This problem persists on either GPU, despite having the latest drivers

It can be is support 3840 x 2160 @144Hz when connecting MPG321UR-QD on NVIDIA 1070 graphic card.

Please refer manual on page 24 to check support list of resolution and refresh rate.
For HDMI cable / 3840 x 2160 @144Hz: * Users have to set HDMI 2.1 to 4K 144Hz - PC.
So please refer manual on page 21 to modify " HDMI 2.1 " to ON first.

It is specification for NVIDIA 1070.
Maximum Digital Resolution: 7680x4320@60Hz
Standard Display Connectors: DP 1.43, HDMI 2.0b, DL-DVI

Thanks again for the reply... I'm well aware of the hardware capabilities of both of my GPU's. I'm even more aware of the MSI manual & its instructions on how to set HDMI to 144hz. It just simply doesn't work. I have no output on the Display Port what so ever... At 60Hz, at 120Hz, or at 144Hz. I have already have an RMA submitted, to return the monitor, as defective... I figure this is the case, as my new Asus PG32UQ works perfectly, upon initial power up (at 60Hz, 120Hz, 144Hz, and 155Hz). I usually swear by MSI products, but this one had issues right from the initial power up (I blame the courier, personally).

Being that this is only a 4K display, I honestly don't care about the 1070's 60Hz 8K resolution limitation.
Aside from the 8K DP Cable that came with the new Asus monitor, I used a Startech DP 8K v1.4 cable (that is factory DP Certified), to test it and it also worked perfectly.

Thanks
