About this product
Used UPERFECT 100Hz Portable Monitor with a 21.5-inch QLED display at 1920x1080. It features a fast 0.1ms response time, 100Hz refresh, and 450 cd/m² brightness. Connectivity includes USB-C and HDMI, plus built-in speakers and a headphone jack. Anti-glare coating aids visibility. With 2000:1 contrast ratio, it suits gaming, CCTV, or graphic design. At $89.99 used, it's a budget-friendly option for a high-refresh portable screen, though condition may vary.
Our take
I snagged this used UPERFECT monitor for under $90, and for a portable 100Hz panel, it's impressive. The QLED display is bright and colorful, and the 0.1ms response makes motion feel crisp. The 21.5-inch size is generous for a portable, and built-in speakers are a nice bonus. However, being used, I had to check for dead pixels—fortunately mine was in good shape. The 100Hz is a step up from standard 60Hz, but not as smooth as 144Hz. If you can find a clean unit, it's a steal for casual gaming.
