2K Laptop Screen Extender, 15.6" Triple Laptop Screen Extender(Wins Only), Foldable Dual Monitors HDMI USB-C Stacked Triple Portable Monitor 180°Rotation, Plug & Play for Laptops PC Phone

Very good first impressions. The construction feels high quality. Worked without problems in extended mode with single USB-C cable under Windows 11 without installation of driver. The buttons on the side are per screen and are useful for quick brightness control. The brightness is high enough. The manual says that brightness over 71% may require connecting the supplied power adapter to the screens - haven't tested this, because I found that 50% is enough for my room lightning conditions. A bonus feature is that the screens can provide power delivery to my low powered laptop via the same single cable (to the laptop) if I connect the laptop's power adaptor to the 2nd USB-C power port of the screens. Another user said that the power delivery is probably limited to 60W - indeed my laptop shows warning that low powered adapter is connected but still charges without problems. The only downsides I can think of compared to some alternatives could be the lack of VESA mounting and HDMI input, but those aren't important for portable usage, which is my case.

Here's some of the answers to questions I'd wish I'd known when purchasing it: - first, the brand name is not present anywhere on the product, so you don't need to worry about misinterpretations if using it processionally - on my M2 macbook air it works out of the box in two modes: both screens joined together as one big screen (useful, but refresh rate of 30hz), or both screens duplicating each other (not as useful, but refresh rate 60hz). Both these modes work via connection with only one USB-C cable. - on my PC (ROG Ally) it works out of the box in two modes: both screens joined together as one big screen (refresh rate 30hz), or each screen functioning as an independent screen (this is the best use case, and refresh rate was 60hz). Both these modes work via connection with only one USB-C cable. - pass through charging works! - plugged in a 100w charger to the middle USB-C port and it charged my Mac or PC via the bottom USB-C port at 60w (which was also the video data port) - It works connected via a single cable to my Macbook air M2 even without either device connected to a charger (power draw is somewhere between 5-10w). - No flickering in either scenario noted, but I did not max out the brightness when not attached to a power source (which usually causes my other portable screens to flicker). That's it for now, will update as I use it further.

It seems like a high-quality monitor but there's one big problem. PROBLEM: I bought this monitor because the pictures show two screens working separately. I need two independent displays for my work. When I connect it to my Mac, both screens only show the same picture. The product only works as one big monitor, not as two separate monitors like the listing shows. REQUEST FOR HELP: I am asking for help to fix this problem. If there is a special setting, cable, or driver I should use, please tell me. I am not trying to be rude. I just want this to work the way it was shown. If you can help me solve this, I will be happy to delete this review. Thank you so much.

Had this for a while and tried multiple laptops, desktops, and OS's and it doesn't work on anything. Biggest waste of money yet, don't buy it

Great product for the money, unfortunately both screens died in under a year with light use.
