Review on 💻 Cocopar J173UH10F Portable Monitor: 4K 3840X2160 IPS, Lightweight 17.3 by Marco Liu

I am very happy with my purchase. The monitor body is durable. This makes it safe and convenient for travel. My laptop screen is 4K resolution. However, I can compare the display quality of portable monitors. I was not disappointed as the screens are identical in quality. Only one cable can be used to connect and power the monitors. As you can see from the picture, the monitor on the left side of my laptop was only connected with one cable while the right one was connected to the DC adapter and the display cable. However, it should be noted that the left monitor, which is powered by a single cable, can only achieve a brightness of 6/10. The difference is visible if you look closely, but personally it doesn't matter much and doesn't cause any inconvenience. I've read a lot of reviews of monitors from other manufacturers, but I've noticed that this problem is very common on portable screens larger than 15 inches in 4K resolution. Using only one cable for each portable screen, no DC power, one of the two screens can only reach 1/10 brightness. I believe this is due to a limitation of my computer. On the other hand, it doesn't cause any problems when you're on the go with just a portable screen, since the main computer supplies enough power. Normally, when traveling, one rarely has the luxury of having space for a computer and two screens. For me, this is ideal when I'm working in a client's office where I have access to a power source. I have experience with other portable monitors (AOC E1649FWU and AOC E1659FWU) but I prefer the new ones I have. The quality is completely different. The old ones were in a plastic case and the resolution is really lower than what I have now.
