Asus TUF RTX 4090 Triple Monitor one or two screens blank out randomly (NOT UFEI ISSUE)

[Ashton_Scott]

I just got my ASUS TUF RTX 4090.  I have a triple monitor setup with a resolution of 7680x1440.  All three monitors are connected to the 4090 with the Display Port cables that came with the monitors.  Randomly (usually when in a game)  the center monitor will go blank, and then a second or two later, come back on. This has MOSTLY happened to just the Center Monitor, however, once it blanked out TWO screens.  

All three monitors are the same LG-27GN800-B's

This is NOT the boot UFEI Issue that can be fixed by a firmware update.  This is completely different.

System Specs:
Windows 11 Pro, ASUS X299 Deluxe, 32 GB Ram, 3x M.2 SSD, 1000 watt powersupply.

Hello, @Ashton_Scott .

If only one LG-27GN800-B is connected, does the game display properly?
Does the issue only occur when two LG-27GN800-B monitors are connected?

To better understand the issue, could you please confirm the following questions:
- the name of the game and are there any related display settings, such as screen extension or display on a single screen?
- the current display settings mode?
- the complete model, BIOS version, and BIOS-related settings of the motherboard currently in use?
- the brand and model names of the CPU, DRAM, and PSU currently installed?
- the OS version and OS build?
- Have you tried connecting the two LG-27GN800-B monitors via HDMI?

Please share the related screenshot of the setting and the video of the problem.
Thank you.

I DO NOT run game in SINGLE monitor mode, even if I did, it doesn’t address this issue.

The name of the game DOES NOT MATTER.  It happens in all my games.

- the current display settings mode?

Display mode is Spanned 7680x1440

- the complete model, BIOS version, and BIOS-related settings of the motherboard currently in use?

ITS NOT THE MOTHERBOARD!!! I had a 2080ti in before I upgraded, this DID NOT happen.

- the brand and model names of the CPU, DRAM, and PSU currently installed?

Same thing

- the OS version and OS build?

It’s also NOT WINDOWS, but Windows 11 Pro.

- Have you tried connecting the two LG-27GN800-B monitors via HDMI?

NO, I HAVE THREE MONITORS, THERE ARE ONLY TWO HDMI PORTS I SHOULD BE ABLE TO USE ALL THREE AS Display Port.

Hello, @Ashton_Scott .

Based on your description, it is difficult for us to confirm the cause of the problem based on your situation and information.
Please refer to ASUS support- service center for further problem detection or assistance.

Thank you.

Agree to the response by mod. If you want help, provide information requested. It is very valid and extremely rude for us consumers to spark an issue with a support team then get immature responses in CAPS. Now with it being months later, what was the cause? My guess, you refreshed the hardware and clean installs and it works.
