About this product
The 17.3-inch 4K 120Hz QLED Gaming Monitor by Uperfect (UColor J5) offers a 3840x2160 resolution, 120Hz refresh rate, and a 3ms response time. It features 500 cd/m2 brightness, a 1500:1 contrast ratio, and an IPS LCD display (listed as IPS LCD). Inputs include USB-C and HDMI Mini. It has built-in speakers, a headphone jack, and is VESA mountable. Designed for serious gaming and graphic design, it is part of Uperfect's 17.3" 4K Portable Monitor line.
Our take
Uperfect's 17.3-inch portable gaming monitor hits a nice balance. The 4K IPS display is sharp and bright enough for most conditions. The 120Hz refresh rate makes motion smoother than 60Hz, though not as fluid as 144Hz. Response time is listed at 3ms, but the title claims 0.1ms—typical marketing. Inputs are limited to USB-C and HDMI Mini, so adapters needed for DVI or full-size HDMI. Speakers are present but weak. VESA mount is a plus. Build is lightweight plastic. At this price, it's a decent option for portable 4K gaming, but you can find better value elsewhere.
