Dell
49-inch QD-OLED; 5120 × 1440 (DQHD), 32:9; 1800R curve

The 32:9 ratio gives a workspace equivalent to two 27-inch 1440p monitors side by side. The 1800R curve keeps the edges closer to the eyes.

MSI
Refresh rate and response time120 Hz (48–120 Hz vertical frequency); 4 ms GtG (Extreme), 5 ms GtG (Fast), 8 ms GtG (Normal); AMD FreeSync Premium

120 Hz at 4K is available over both HDMI 2.1 and DisplayPort 1.4; the source must also output 4K at 120 Hz. FreeSync Premium matches the refresh to the game’s frame rate within 48–120 Hz to prevent tearing; AMD’s tier also includes low framerate compensation (LFC). GtG figures are given for the fastest overdrive mode.

HDR10 support means the monitor accepts HDR signals; with 300 nits and edge lighting it carries no DisplayHDR tier. 1.07 billion colours corresponds to 10-bit colour depth.

Refresh and response—144 Hz (adaptive range 48–144 Hz); 0.03 ms (GtG)

Adaptive sync prevents tearing while the frame rate stays between 48 and 144. Reaching 144 fps at full resolution needs a very powerful graphics card.

MSI
