Ultra-Light OLED 4K Portable Monitor

The Uperfect BE133BU is a 13.3-inch OLED panel delivering 3840 x 2160 resolution at 60 Hz. Weighing 463 g, it targets digital nomads, remote workers and colour-critical creatives who need reference-grade accuracy while travelling. The 100000:1 contrast ratio and 109% DCI-P3 coverage provide deep blacks and wide gamut for photo editing and video grading on the move.

Dual USB-C and Mini HDMI Connectivity

Two full-function USB-C ports and a Mini HDMI input accept video and power from laptops, MacBooks and phones supporting DP Alt Mode over USB 3.1 or Thunderbolt 3.0 and 4.0. A single cable can carry both signal and power, though external power is recommended for sustained brightness. The VESA 75 x 75 mm mount lets users attach the monitor to arms or stands, freeing desk space in compact home offices or mobile setups.

Sustained Colour Accuracy Under Load

The OLED panel maintains 400 cd/m² brightness and 1 ms response time during extended sessions, keeping colour volume stable for long grading or editing tasks. Built-in speakers handle basic audio without extra peripherals. The aluminium alloy chassis resists flex and dissipates heat passively, so performance does not throttle during continuous professional use. Buyers needing higher refresh rates or HDR certification beyond the stated specifications should look elsewhere.

Questions about this item

Does the 60Hz panel limit how long I can work before motion blur appears?

The 60Hz refresh rate and 1ms response time keep motion clear for typical office and creative tasks during all-day sessions.

How hot or loud does the aluminium chassis get after hours of continuous 4K output?

The fanless aluminium frame runs silently; surface warmth stays low because the OLED panel draws modest power at 400 cd/m² brightness.

Which cable and port must my laptop already provide to drive 3840×2160 at 60Hz with one wire?

A USB-C port that supports DisplayPort Alt Mode — Thunderbolt 3.0 or 4.0 also works — delivers video and power over a single cable.
