How to read this comparison

Manufacturer facts for the exact models shown. Not a quality rating or a test result.
“Different” means the known values differ, not that one is better.
Missing or conflicting evidence is marked and never counts as a difference. Source chips hold each fact’s sources and conditions.

Match the monitor to the connection. Refresh limits depend on the input, cable and source device. Confirm the exact regional ports, stand adjustment and mount. Manufacturer response-time methods such as MPRT and GtG are different; neither the image nor these figures establish an independent motion or colour-quality test.

WHAT EACH CHOICE ASKS OF YOU

What it brings and what to check

MSI MPG 341CQPX QD-OLED

What it brings

240 Hz at 3440 × 1440 over DisplayPort, HDMI 2.1 or USB-C, a 0.03 ms GtG response rating and 99.3% DCI-P3 (CIE 1976), with USB-C video, 98 W charging and a USB hub.
Manufacturer source
PIP/PBP is supported, and the 3-year warranty covers panel burn-in.
Manufacturer source

What to check

The 1000 cd/m² HDR figure applies only in Peak 1000 mode at 3% APL (450 cd/m² in True Black 400 mode at 10% APL), and the USB hub ports are USB 2.0.
Manufacturer source

MSI MPG 491CQPX QD-OLED

What it brings

The 5120 × 1440 panel reaches 240 Hz on every input with a 0.03 ms GtG response rating and 99% DCI-P3 (CIE 1976), and PIP/PBP plus KVM let two computers share the screen and peripherals.
Manufacturer source Manufacturer source

What to check

With the stand it is 1195 mm wide and 328 mm deep, so it needs a large desk.
Manufacturer source Manufacturer source
The stand has no portrait pivot and the hub is USB 2.0. The 1000 cd/m² HDR figure applies only in Peak 1000 mode at 3% APL; typical SDR brightness is 250 cd/m².
