Real-world verdict

The AW3225QF is a 31.5-inch 4K 240 Hz QD-OLED curved gaming monitor — desk-native, with DisplayPort 2.1 and the highest refresh of the two. The LG C3 is a 42-inch 4K 120 Hz OLED TV: flat, much larger, and brilliant as a couch / living-room or sim-rig panel, but it is a TV (no DP2.1, 120 Hz cap, heavier UI). Desk gaming → AW3225QF; big-screen living-room or immersive single-player → C3. Both are OLED, so apply the same burn-in care.
