ASUS ROG XG27VQ - Dims out on sides randomly

Hi,

I bought an ASUS ROG XG27VQ monitor in last July 2019. Just around 10-15 days ago this issue started occurring where the screen randomly dims out on the sides of the monitor. Switching it off every-time & turning it back on fixes the issue but it happens at-least once everyday now. Around 2-3 days back i tried some things on the software side but didn't help except one when i turned off adaptive sync it seemed to run properly for 3 days buy today the issue happened again. Somehow i think that this is a hardware issue & i am worried that i might have to go for a replacement but still want to see if anyone else has faced a similar issue with any ASUS monitors.

Attaching screenshots of what it looks like
