Sold an MSI 341CQP and moved to the XG34WCDMS mainly for the higher refresh rate and day-to-day quality-of-life features; in games, apart from slightly higher perceived brightness, the newer panel isn't a big step up.

“I have since sold the 341CQP and upgraded to the XG34WCDMS that also have the newer gen display.”

A month into heavy work and gaming on the XG34WCDMS, it ran only 4 pixel cleanings in 329 hours, far fewer than a friend's identical unit.

“For me it seems that the monitor is not doing the Pixel Cleaning properly when it goes to sleep.”
