G3223Q, yellow tint, bright spot
Received the monitor a couple of days ago. Same issues as described in other posts - yellowish tint (I had two 27 in chUltraSharp, I replaced one with the G3223Q, so it is being compared to the U2720QE next to it), blacking out during gaming (seems like G-Sync is the culprit). Also, there appears to be a screen defect (not quite a dead pixel but a larger piece of excessively bright spot visible in white background). Also, not nearly as bright as the U2720QE. Called customer service, factory reset helped a bit with the yellow tint, not the rest. The monitor has the latest firmware, M3T103, runs off RTX4090 Strix with the latest Nvidia driver, through a DisplayPort connection (cable from the G3223Q box). Dell is sending me a replacement screen (remarkably responsive customer service!), hopefully a better one. Other than that, I really want to like this screen :). I have had Dell monitors at both work and at home for as long as I can remember.
