ASUS ROG Swift PG27UCDM

■ The catch — co-equal billing, always
It's $1,100 for a 27-inch. MSI's MPG 321URX puts the same 4K 240Hz QD-OLED on a bigger 32-inch canvas for about $240 less — the PG27UCDM's premium buys higher pixel density, DisplayPort 2.1a and Dolby Vision, not a fundamentally better panel.
Dealbreaker? Runner-up №1 is the same panel at 32-inch for less ↓

Traps — this verdict avoids
Burn-in is a warranty question
OLED burn-in from static taskbars, HUDs and desktop icons is real — pixel-shift, ABL and proximity sensors reduce but never eliminate it. Buy the panel with the longest coverage; the MSI QD-OLEDs here carry a 3-year burn-in warranty.
OLED HDR has a brightness ceiling
Full-screen HDR on OLED tops out at 250-400 nits versus 1,000+ nits on Mini LED. In a bright, sunlit room OLED HDR can look dim — if your desk gets direct sun, a Mini LED panel may serve HDR content better.
Your GPU may not feed it
High-refresh OLED (360Hz+, or uncompressed 4K 240Hz) needs DisplayPort 2.1 UHBR20 or DSC compression. An older graphics card without it can't drive the panel at full spec — verify your GPU before you buy.
