7900xtx DisplayPort black screen

OS: Win 11 version 2252

Cpu: Ryzen 5 3600 (I am upgrading this in due time)

Ram: Corsair 32GB DDR4 3200MHz

Mobo: B550 AORUS ELITE (rev. 1.0)

PSU: Evga gold rated 850W

GPU: Sapphire pulse 7900xtx (connected with 3 separate power cables)

Monitor: 32' Odyssey G52A QHD Gaming Monitor connected via DisplayPort

                2nd monitor is HP 27xq connected via HDMI ( No Problem)

Radeon Driver 23.5.2

Just installed the 7900xtx and I am getting black screens frequently occurring when I am connected via the Display port, the monitor is set to 165hz, and it is less prominent if I change to 144hz, this happens at any time sometimes in quick succession and sometimes it won't happen for a couple of minutes.

Things I have tried with no success:

Changing monitor between dp vers 1.1 and 1.2

Changing to new Cable which is dp 1.4 (the previous version was 1.2 which is what the monitor is)

Re-installing Radeon Driver

Reseating Ram

Clearing Cmos

There is NO issue when I am connected via HDMI only DisplayPort and I had NO issues on the previous GPU which was a 5700xt, can anyone please help me understand what is going on here?

Thank you

Hello, Update GPU Firmware and Drivers: Ensure that you have the latest firmware and drivers installed for your Sapphire Pulse 7900XTX GPU. Visit the manufacturer's website to download and install any available updates specifically designed for your GPU model. Check DisplayPort Cable: Although you mentioned trying a new DisplayPort cable, it's still worth double-checking the cable's quality and compatibility. Ensure that the cable is certified for DisplayPort 1.4, supports the required bandwidth for your desired refresh rate (165Hz), and is securely connected to both the GPU and the monitor. Adjust Display Settings: Try adjusting the display settings on both the GPU driver software and the monitor itself. Experiment with different refresh rate options and other relevant settings to see if there's any improvement or stability. Power Supply: Check if your power supply unit (PSU) is providing enough power to the system. Verify that the PSU's wattage rating is sufficient for your components, especially considering any future upgrades you mentioned. GPU Temperatures: Monitor the temperatures of your GPU during operation to ensure it is not overheating. Excessive heat can cause instability and black screen issues. Ensure proper airflow within your computer case and consider additional cooling if necessary. Contact Manufacturer Support: If the issue persists, consider reaching out to the manufacturer's support team for further assistance. They may have specific troubleshooting steps or suggestions based on your GPU model. UPSer
