The switch between 4K at 160Hz and 1080p at 320Hz is the first thing we tried on the XG27UCG, and it's the reason this is our default pick. Most 4K monitors ask you to choose between detail and speed; this one lets you keep both on one desk. The 27-inch Fast IPS panel is sharp at desktop distance, and the 95% DCI-P3 coverage gives games more saturation than a plain sRGB panel. USB-C is a welcome extra for a laptop, and G-Sync Compatible plus FreeSync Premium covers both graphics-card camps.
What keeps it at the top is the balance. 160Hz is high enough for fast shooters without demanding the GPU headroom of a 240Hz 4K panel, and the FHD 320Hz mode is a genuinely useful fallback for competitive games. DisplayHDR 400 is a modest HDR experience, not a reason to buy, but the SDR picture is what most games will use anyway.
The stand adjusts height, tilt, swivel, and pivot, and the 27-inch size keeps pixel density high while leaving room for a second screen. The matte finish handles a window behind the desk better than the glossy OLED here. It isn't the deepest-black monitor in this group, but the 27-inch size and matte finish make it the easiest to live with day to day.
Pros
- Dual-mode 4K 160Hz / FHD 320Hz
- USB-C plus G-Sync and FreeSync support
- 95% DCI-P3 color coverage
Cons
- Some units can cut out intermittently
We recommend the XG27UCG as the default 4K gaming monitor because its dual-mode panel, USB-C, and G-Sync support cover PC and console play without the OLED premium.
