Pros & Cons Side by Side

LG C3 OLED 42-inch Gaming TV/Monitor

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

165Hz at 1440p is the sweet spot for GPU performance and visual quality

G-Sync Compatible and FreeSync Premium for both major GPU brands
Most affordable 1440p 165Hz Quantum Dot monitor available

IPS contrast ratio (1000:1) trails VA panels for dark scene gaming
Not OLED — LG and Samsung OLED panels deliver superior black levels
Stands are notoriously plastic-feeling on MSI budget tier
