MSI MPG 341CQPX adaptive sync issue

[BuzzingBee]

UPDATE: As per store policy I've given my monitor to their store and they'll send over to MSI for warranty. I'm really hoping they will pick up this issue as I admit it's a bit difficult to notice unless someone has a good eye. If this issue can be fixed via firmware in the future, then I'm heavily disappointed that we're now in an era that PC hardware can be shipped broken and later rely on feedback to fix later via firmware, just like games. Or more simply it may be a bad luck that I received a faulty monitor.

A couple months back I was considering upgrading my monitor, then fast forward to few days ago, yep I pulled the trigger on MSI MPG 341CQPX, 3440x1440 240Hz QD-OLED.

 

I was going to make a post of my thoughts on it one day, but instead I came across a deal-breaking issue in which adaptive sync isn't properly working and getting juddering. There goes my first impressions.

 

It does eliminate screen-tearing when comparing adaptive sync off/on, but I believe the monitor's refresh rate is not matching in game's FPS and instead fixed at 240Hz, so it creates juddering. I've tested with my other monitors and TV aswell with my main PC with AMD GPU and my laptop with Nvidia GPU, so surly it comes down to that monitor.

 

It's hard to spot at first, but I knew something is off when the motion isn't perfectly smooth. Which brings to today which I decided to investigate and found out by going to RivaTuner and enable frame color indicator to 2 bars to examine sync behaviour (solid-ish white colour = no tear/stutter, tear lines = screen tearing, rapid flashing = stuttering, left & right bar flashing differently = juddering). Another way to test juddering is I capped FPS around 90% of refresh rate (e.g. 216 FPS for 240Hz), revealing juddering at its worst. 

 

I'm honestly bummed about it because otherwise I liked everything else about it. But perhaps I'm missing something? Is there something else I haven't yet tried? 

 

EDIT: Replaced micro-stuttering with juddering

I'd say this is a defective unit, since this should be seen even with basic testing during product development for a gaming monitor.

 

I assume you made sure FreeSync is set up properly?

 

I only ever used Nvidia GPUs so Idk if there is a bunch of options you need to tweak. With G-Sync there are several GPU driver settings you need to tweak to make sure G-Sync runs properly.

For AMD it's more simple, for their settings I need to select connected display first then it has adaptive sync on/off toggle individually.

 

I made absolutely sure I set up FreeSync properly, as mentioned above I went back and tested a lot of my other displays: my old ultrawide, my side monitors and my TV were all working fine, and I also double checked with Rivatuner method showing two bars solid-ish white.

 

Anyway, it already got sent off so I probably need to wait at least three weeks until results come in.
