Buying advice

The 45GX950A-B is for buyers who want a highly immersive 800R OLED ultrawide without giving up 5K2K text and desktop detail. Its dual-mode refresh adds flexibility, but the enormous footprint, aggressive curve and GPU demand make it a deliberate high-end choice rather than a general-purpose monitor.
