- Dell UltraSharp 52 supports splitting the screen across up to four desktops
- Each virtual desktop measures 1536 x 2560 when divided into four sections
- The panel uses IPS Black technology and supports 120Hz variable refresh rates
At CES 2026, Dell introduced the 52-inch UltraSharp Thunderbolt Hub monitor (U5226KW), which measures 48.16 inches wide with a panel marketed with a resolution of 6144 x 2560.
According to the company, the screen can be divided into up to four different virtual desktops, allowing separate content spaces on the same screen.
The large size of the monitor means that users may need to move their head and neck frequently to view the full screen comfortably.
Pixel density below the 6K standard
Despite the advertised 6K resolution, the horizontal and vertical pixel count does not fully comply with the 6K format standard, meaning it does not offer the exact pixel density of a real 6K display.
Its listed pixel density is 129 pixels per inch, roughly comparable to that of a 32-inch 4K monitor.
When divided into four virtual desktops, each section measures 1536 x 2560, and when divided into three, each measures 2048 x 2560.
The monitor uses a Black IPS panel with support for variable refresh rates and a 120Hz refresh specification.
It supports wide viewing angles of 178 degrees both horizontally and vertically and has a curvature of 4200R.
Native contrast is rated at 2000:1 and maximum brightness is specified at 400 cd/m².
For color coverage, it supports 99% of the DCI-P3 color gamut and 100% of the sRGB and BT.709 gamuts, with a calibration accuracy of E < 1.5.
Anti-glare and low-reflection treatments are applied to the screen surface, and low blue light and flicker-free technologies are included.
The business monitor also has certifications, including TCO Certified 10.0, EPEAT Gold, and Energy Star compliance.
Connectivity options include two HDMI 2.1 ports capable of 6144 x 2560 resolution at 120 Hz, two DisplayPort 1.4 ports, and a Thunderbolt 4 upstream connection with 40 Gbps throughput.
Additionally, there are three USB-C upstream ports and four USB-A downstream ports, along with two USB-C downstream ports offering up to 27W of power.
Also included are a 2.5GbE RJ45 Ethernet port and an integrated USB hub and KVM switch.
Its stand allows for height, tilt, tilt and swivel adjustments, and the panel is VESA mount compatible.
The operating power consumption of this large monitor is 63.6W, with a maximum consumption of 430W.
It is compatible with Windows, Linux, Mac and ThinOS and includes a three-year limited service with advanced exchange and premium panel replacement.
