ASUS ROG Swift PG32UCDMZ vs MSI MPG 491CQP
Both sit in the same price bracket, so the question is not which is better but which suits you. Below are the real differences, then who each one is for.
The differences that matter
- Smoothness: the ASUS ROG Swift PG32UCDMZ runs at 240 Hz and the MSI MPG 491CQP at 144 Hz. That is 96 Hz apart, enough to notice when swinging the camera in fast shooters, provided your machine produces those frames.
- Sharpness: the ASUS ROG Swift PG32UCDMZ is 4K and the MSI MPG 491CQP is DQHD. On screen that is 140 against 108 pixels per inch, and it shows most in text.
- Panel type: QD-OLED on the ASUS ROG Swift PG32UCDMZ and Curved QD-OLED on the MSI MPG 491CQP. This is the difference that changes most of what you see: it decides contrast and how much motion smears.
- Size: 49 inches against 31.5. At normal desk distance the larger one covers more field of view; the smaller one can be read whole without moving your eyes.
Which one suits you
Choose the ASUS ROG Swift PG32UCDMZ if
- you want the cleanest motion possible
- you want the most sharpness
- you mostly play competitive shooters

Highlighted rows are where the two monitors differ. The ▲ mark points to the better value where one can be named objectively; on fields like panel type or size there is no «better», it depends on what you want.
Size, resolution, panel, refresh rate and response time are each checked against the manufacturer's listing on Amazon.es. Anything we could not confirm shows as “—”: we would rather leave a gap than invent a figure.
