TL;DR
Dell unveiled the UltraSharp 52 (U5226KW) at CES: a 52-inch, 6K IPS monitor that can be split into up to four virtual desktops and accept inputs from multiple devices. It ships in January for $2,899 and includes a broad set of ports including Thunderbolt 4 with up to 140W power delivery.
What happened
At CES Dell introduced the UltraSharp 52 (U5226KW), a single 52-inch 6K monitor designed to replace multi-panel desktop setups by dividing its panel into up to four virtual screens. The panel is 6144 x 2560 resolution with a 21:9 aspect ratio, yielding about 129 pixels per inch. Dell says the display supports inputs from up to four different devices or can present multiple desktops from one computer. The company positioned the product as a cleaner alternative to three or four individual monitors, noting the new panel is roughly 48.16 inches wide and would take up about the desk space of two 27-inch monitors while delivering three or four times the desktop area. The UltraSharp 52 will be available in January for $2,899 and includes a wide mix of ports, including HDMI 2.1, DisplayPort 1.4, Thunderbolt 4, and multiple USB-C and USB-A connections.
Why it matters
- Eliminates bezels and gaps associated with multi-monitor arrays while offering comparable or greater desktop area.
- Supports multiple simultaneous inputs, enabling several devices to feed discrete virtual screens without extra displays.
- Thunderbolt 4 port supplies substantial laptop power (up to 140 W), reducing the need for separate chargers.
- High native resolution and broad color coverage suit mixed workflows that need lots of on-screen real estate.
