This was tested on an old laptop, a computer with a 3070 GPU, and a phone. It could be easily connected to computers via a USB-HDMI cable. The phone tested was an old Galaxy S8 phone. No connection is established despite using different apps. Can't tell if it was the phone or the apps used to connect, but nothing I've tried has worked. When connected to my computers it worked as intended. Monitor response time isn't great, nor is color reproduction, but that's to be expected at this price point and I wouldn't turn it down. For those who want an easy-to-carry laptop monitor, this is a good solution when you factor in the extra stand. While the video quality on the monitor is good, the stand that comes with it (not the optional stand) needs an upgrade. I could hardly keep the monitor steady for more than a few minutes. It's totally inadequate and I had to use tape to keep it from falling off. If the grooves holding it in place were deeper, it would likely hold the monitor in place. Two positions are available, and each allows the monitor to slide out of the shallow channel in just a few minutes. Any movement of the table he was sitting on would immediately destabilize him and cause him to fall. The more standard stand that comes with it instead of the included version is really the only viable option. It worked really well and was very stable. Also, you can rotate it from landscape to portrait. This is a great feature and I used it to read documents while working on a project on my computer. Another small addition to this product that I liked but was a bit disappointing is the hex head/screwdriver combination tool that attaches to the underside of the stand base. It is used to tighten or loosen bolts in connections that allow rotation or rotation. However, it is very firmly built into the bottom of the stand. You need something small or sharp to get this sucker out of there, but at least they delivered it. Maybe adding an underlying ribbon of fabric that you can pull to remove the tool would help.
