What just happened? With the start of CES 2025 now just days away, companies are rushing to reveal their new products ahead of the world’s biggest consumer electronics event. Three tech giants have just unveiled 27-inch 4K OLED 240Hz monitors, and at least two support DisplayPort 2.1a.

Asus, Samsung, and MSI have announced their claims for producing the world’s first 27-inch 4K OLED 240Hz monitors, all using Samsung’s 4th-generation QD-OLED panels.

The Asus ROG Swift OLED PG27UCDM, which has a screen size of 26.5 inches, boasts a peak brightness of 1,000 nits, HDR10 and Dolby Vision support, a 0.03ms response time, VESA DisplayHDR 400 True Black compliance, and more.

MSI’s monitor is the MSI MPG 272URX QD-OLED. Its spec list shares many similarities to Asus’ monitor, while also including support for VRR and ALLM (Auto Low Latency Mode). It’s DisplayHDR 400 True Black compliant and ClearMR 13000 certified – the latter is the highest tier for the metric that compares the ratio of clear pixels to blurry pixels during motion. It offers a 166PPI display, but there’s no Dolby Vision HDR support.

The final monitor is Samsung’s Odyssey OLED G8. Like the others, it boasts VESA DisplayHDR True Black 400 and G-Sync/FreeSync Premium Pro compatibility, along with 165 PPI on its screen.

Both new monitors from Asus and MSI include DisplayPort 2.1a (UHBR20). The standard offers 80Gbps bandwidth, allowing users to enjoy 4K at 240Hz without the need for Display Stream Compression (DSC). Samsung doesn’t say anything about DisplayPort 2.1a in its release, but it’s fair to assume that it’ll be there.

The monitors also support HDMI 2.1; it was recently confirmed that HDMI 2.2 will be unveiled at CES, but it’ll be a long time before that standard appears in monitors and consumer televisions.

The monitors come with advanced OLED protections, such as MSI OLED care 2.0 and Asus OLED care Pro. Those two companies also offer a three-year warranty that includes burn-in protection. Samsung has yet to confirm its warranty specifics.

Last week we heard that LG plans to unveil new UltraGear OLED monitors at CES, including a 45-inch 5K2K bendable model with dual-mode functionality. Asrock also has an upcoming dual-mode monitor with built-in Wi-Fi 7 antennas.
