I'm currently using this monitor. For the price, it's not bad since you're getting 165hz refresh rate. Got it for less as a pre-order on Lazada.

Looks good when playing Warzone and other games like Control. Speakers are ok, not the best. But I use headphones most of the time anyways.

I hook it up with my PC and PS4 at the same time. But, I kinda agree on the pixelations issues tho, especially when watching Youtube. But, it's a minor thing for me as long as you don't look that closely on the screen. Can't say much on the black smearing thing. Haven't noticed it I guess.

Hope this helps
