Pros & Cons Side by Side

ASUS ROG Swift OLED PG32UCDM 4K 240Hz

4K OLED at 240Hz — the highest resolution and refresh rate combination in an OLED gaming monitor
0.03ms response time combines 4K detail with OLED speed simultaneousy
Thunderbolt 4 connects MacBook Pro or creative workstation with single cable
HDMI 2.1 supports PS5 4K/120fps and Xbox Series X at maximum specification
99% DCI-P3 professional colour accuracy — the only 4K OLED gaming monitor reviewed with Thunderbolt 4

£1,500+ is the highest price reviewed — the premium display for those who've stopped compromising
4K at 240Hz requires RTX 4090 or equivalent to exploit fully — GPU investment required
32-inch 4K OLED burn-in risk with static elements — screen saver discipline needed

LG C3 OLED 42-inch Gaming TV/Monitor

OLED evo panel delivers perfect blacks and infinite contrast that gaming monitors can't match at any price
42-inch at 4K OLED delivers an immersive gaming experience fundamentally different from 27/32-inch monitors
0.1ms response time matches OLED gaming monitors at a larger screen size
VRR (Variable Refresh Rate) compatible with PS5, Xbox and PC simultaneously — one screen for all platforms
Dolby Vision Gaming mode enhances HDR in compatible titles including Microsoft Flight Simulator and Forza

42-inch requires viewing distance of 1.5m+ — desk use only works with proper ergonomic setup
TV OS alongside monitor use — WebOS ads and UI present when not gaming
£800+ for a 42-inch screen requires room-specific setup rather than desk setup
