With Asus celebrating the 20th anniversary of its Republic of Gamers brand, it's no surprise that the company unveiled multiple ROG gaming monitors at Computex, including the 540Hz ROG Strix OLED XG259QWPG Ace, touted as the first OLED esports monitor.

Asus also launched a wide assortment of other displays, including TUF gaming monitors, three ProArt creator panels, two video-conferencing monitors, and several ZenScreen portable monitors, including the MP13UC, a 13.3-inch ePaper display designed to reduce eyestrain.

A Killer Refresh Rate and OLED in a 24-Inch Esports Panel

Asus calls its ROG Strix OLED XG259QWPG Ace the world's first 24.5-inch OLED monitor designed specifically for pro esports gamers. It features an FHD (1,920-by-1,080-pixel) TrueBlack Glossy Tandem WOLED panel with a 540Hz refresh rate and a claimed 0.2ms response time. According to the company, with Tandem white organic light-emitting diode (WOLED) technology, the monitor provides up to 15% higher peak brightness, 25% larger color volume, and 60% longer OLED lifespan versus previous-generation WOLED panels. Meanwhile, the TrueBlack glossy coating sharpens both images and text.

Through its partnerships with esports tournament organizers Blast and PGL, ROG collected feedback from professional gamers, enabling them to tailor the XG259QWPG Ace for esports pros. Precise measurement markings on both the monitor's stand and base let gamers adjust their preferred setup. In addition, a Quick OSD menu lets players tweak core settings before every game. The XG259QWPG Ace includes three Esports Color modes. It also features VESA DisplayHDR 600 True Black compliance, 99.5% DCI-P3 color gamut coverage, 10-bit color, and Delta E color accuracy of less than 2. As with the other new products mentioned here, price and availability information have yet to be announced.

A Portable ePaper Panel to Reduce Eye Fatigue

The Asus ZenScreen Color ePaper MP13UC is a 13.3-inch display with 3,200-by-2,400-pixel resolution and a 300ppi pixel density—exceeding that of Apple's Retina displays found on the company's monitors, MacBooks, and iPads—and support for 4,069 colors. EPaper is a display technology—best known from the E Ink brand commercialized by E Ink Corporation and widely used in ereaders—that supports ultra-high pixel densities, reflects ambient light, remains readable in bright sunlight, and greatly conserves battery life. Unlike traditional ePaper, the monitor has a 35Hz refresh rate to facilitate scrolling and viewing dynamic content, and includes Asus Ghosting-Free technology for crisp text and vivid visuals.

This TÜV Rheinland-certified monitor minimizes blue light and flicker. Integrated touch functionality allows for intuitive navigation and interaction, making it ideal for document review, extended browsing, or focused study sessions.

The MP13UC includes the foldable ZenScreen ATS01D stand for full ergonomic flexibility with height adjustment (7.5-14.4 inches), tilt, and 90-degree pivot. Whether on a desk or a tripod, the 1.9-pound, foldable design ensures a space-saving and comfortable mobile workstation. The ZenScreen ATS01D supports up to 16-inch displays and is VESA mount-compatible. This stand will also be available for purchase as a standalone product.  

A 5K Gaming Monitor With Creative Chops

In addition to the two monitors highlighted above, the Asus Computex launch introduces a wide variety of other displays. Among them, in the gaming arena, the ROG Strix OLED XG32UQWMS is a 4K dual-mode 32-inch WOLED panel with technology similar to the XG259QWPG Ace, and the ROG Strix 5K XG27JCEG is a 5K gaming monitor with creative chops. The company also refreshed its TUF gaming monitor line. Plus, three new ProArt 4K QD-OLED graphic arts panels are coming, with the ProArt Display OLED PA32USD at the pinnacle, featuring a Delta E of less than 1 and 1,000 nits peak brightness.

In addition to the MP13UC ePaper display described above, newly announced portable monitors include the ZenScreen OLED MQ14FCKV, a featherweight 14-inch OLED panel, and the ZenScreen Duo MB14FCD, which features a hinged pair of 14-inch 16:10 FHD IPS panels. Lastly, the BE34WCGNK and BE27ACGNK video-conferencing monitors​ feature 5MP webcams, Microsoft Teams integration, and other teleconferencing-friendly features.

About Our Expert

Tony Hoffman

Senior Writer, Hardware

Since 2004, I have worked on PCMag’s hardware team, covering at various times printers, scanners, projectors, storage, and monitors. I currently focus my efforts on 3D printers, pro and productivity displays, and drives and SSDs of all sorts.

Over the years, I have reviewed smart telescopes, iPad and iPhone science apps, plus the occasional camera, laptop, keyboard, and mouse. I've also written a host of articles about astronomy, space science, travel photography, and astrophotography for PCMag and its past and present sibling publications (among them, Mashable and ExtremeTech), as well as for the former PCMag Digital Edition.

The Technology I Use

I have a Lenovo ThinkPad T14 laptop that's my work daily driver, an HP Pavilion Aero 13 as my primary personal laptop, and an Asus ProArt P16 for detailed photo work. (I also have an older Dell XPS 13, which now stays at home full-time.) For storage testing, I rely on our three custom-built Windows testbeds in PC Labs, as well as a 2024 MacBook Pro.

My primary home monitor is a BenQ EX2780Q, a gaming monitor with a great sound system and excellent image quality. I use that panel for writing, watching videos, and working with photos. I also have an HP 27 Curved Display—one of the first general-purpose curved monitors—which I have paired with an Acer Aspire desktop computer. My multifunction printer is an Epson Expression Premium XP-7100 Small-in-One. I also own an Epson Perfection V39 flatbed scanner, which I use for photos and short documents, and a Canon Selphy CP1300 small-format photo printer for turning out snapshots.

My first cell phone, in 2006, was a Motorola Razr; since then, it’s been all iPhones—I currently have an iPhone 15 Pro. I use my iPhone a lot for casual photography, though I also use a Sony DSC-RX100 VII and a Canon G5 X Mark II for everyday shooting. For much of my travel photography and astrophotography, I use either a Sony A7r II or A7 III, paired with a variety of lenses ranging from a Sony 14mm f/1.8 prime to a Sony FE 70-300mm f/4.5-5.6 G OSS zoom lens. I also pair the A7r with a RedCat 51 for deep-sky star shooting. For astrophotography, I also use the Seestar S30 and S50 and the Unistellar Odyssey smart telescopes, which are essentially astronomical cameras controlled through one’s mobile device.
