A great portable monitor for extending the screen with a single USB-C cable—in my case, from the laptop or the Legion Go S (PC handheld). The image is "simply" beautiful, but not as color-accurate as a standard IPS monitor. To be honest, you don't really notice that, and that isn't what you buy this monitor for anyway. Gaming on the PC handheld works fine too. I set the refresh rate to the second-to-last speed via the on-screen menu. It can go one notch faster, but then you regularly see artifacts, even with steady images like typing on the laptop.
Additionally, the 1/4-inch screw on the back is very nice, allowing you to attach the monitor to a "selfie tripod" and position it at various heights. I can confirm that this works great with the ULANZI MT-73 tripod. The screen then sits nicely above/vertically above the laptop screen. The monitor can be powered directly or indirectly via USB-C (power pass-through works). The official power output (nominal or max.) that this monitor can transmit via USB-C has not been published anywhere. I tested with a 100-watt USB-C charger that the monitor can be connected via both [charger > monitor > laptop] and [charger > laptop > monitor]. In both cases, the monitor is powered (max. 15W consumption) and the laptop is sufficiently recharged. However, when testing the PC handheld and a demanding game (continuous consumption of at least 45W - 55W), it seems more advantageous not to connect the charger to the monitor first (i.e., via [charger > handheld > monitor]), as the charging time of the PC handheld appears to be slightly faster. Conclusion: for typing and browsing the internet, the monitor transmits sufficient power to the laptop, but with continuous high power consumption, the monitor does slightly reduce the current during transmission. Finally, every portable monitor should really have an HDMI port in addition to USB-C ports, and this one does! This offers a lot of freedom, for example, if you need to connect a Nintendo Switch in a spontaneous situation while on vacation [ nintendo > usb-c hub with HDMI > monitor ] or encounter a computer system that only has HDMI.
The only two downsides: the included USB-C to USB-C cable broke after just 3 weeks, without any visible external damage or wear (it was properly replaced by customer service with an alternative), and the sound from the two rear speakers is worthless. You shouldn't buy it for the "speakers."
