Can't get ProArt Display to work

[ANDY_ASUS]

Bought two Pro Art 27" Monitors for my photography a month ago, but can't get either to work on Alienware PC. Troubleshooting guide does not help. If I plug my old 27" dell monitor in with the Displayport cable, works fine. I can change the cable to connect to the Asus and once or twice it worked. However, as soon as I attach Asus and Reboot and PC just keeps beeping and won't boot (6 beeps meaning Video card/chip failure).

So PC (dell6core i7) works fine with Dell 27" monitor, but not with Asus 27", both using Displayport.

I have checked the cables and selected displayport on the OSD menu, no help. I am guessing I will need to change the video card, which is a GeForce GTX760ti. It has a maximum resolution of 2560x1440. Could that be the issue?

Thought it might need a driver installed, but if it halts at Bias, this is before the driver.

Any Help appreciated

Here is the video (apologies for poor camera work). I start with the dell 27" working and then shutdown and attempt to boot the Alienware PC. As the video exceeded the max size, I have separated it into two videos.

Video too big, will reshoot tomorrow

Hopefully that has worked because it tells me I do not have permission to upload video.

Could using a DP switch help isolate the two sides of the DP cable, in case there was something incompatible?

Hi @ANDY_ASUS ,

Thank you for your response. 

Before we proceed with submitting the issue for further review of your monitor, we recommend contacting Alienware's official support team to verify the issue related to the six beeping sounds. 

This might be caused by an older graphics card that may not fully support the features of the ProArt monitor. 

Please confirm with Alienware support and let us know if additional assistance is needed. Thank you!
