Review on ASUS XG17AHPE Portable Adaptive Sync Micro HDMI 17.3", Full HD 1920x1080, 240Hz, HDMI, IPS Display by Paul Llena

Works as advertised and supports itself without power when connected to the appropriate TB3, USB, VirtualLink port. This is the easiest to achieve and ideal for small form factor PCs and RTX cards. I suspect some laptops have a different USB-C power delivery behavior, so it's good that you can also support a monitor with a dedicated USB-C DC-IN port that is separate from the DP-IN USB-C is. Because of all these variations, this is the best in the portable monitor class.
