Ranked #2 in Gaming Monitors
Backed by 4 cited sources

RTINGS' best gaming monitor of 2026: a 4K 240Hz 4th-gen QD-OLED with the highest OLED pixel density (~166 PPI), DisplayPort 2.1a UHBR20 and 90W USB-C. Only its ~$1,100 price - versus the identical-panel Alienware - keeps it from being the obvious buy.
