Review on UPERFECT Automatic Touchscreen: 15.6" Ultrawide Frameless Portable Screen with 3840X2160 Resolution by Trevor Wilcox

PROS:+Good screen/touch screen and build quality is very good+All cables you need to connect+Packaging is very good+User manual is actually nice and informative with visual elements+Touch OSD menu with many settings+You can only use with a USB-C cable for some devices that support it + a good number of ports (and both USB-C ports can be used as video inputs) CONS: - Random black lines sometimes flicker when looking for it (this can only be my device ) ->Warning: The replacement didn't show any black flickering - Comes without a case - Price is a bit high - Speakers I bought this monitor because I needed a portable monitor that can also do 4k. I have previously bought another 4k portable monitor from a different brand but it didn't work at all with my Macbook Pro 16 2019. This monitor was completely on and off and my Macbook Pro 16 would flicker on the desktop and not sync to the monitor. This only worked when the MacBook was in Safe Mode. Hell, it didn't even work with my phone or iPad Pro. REVIEW: This portable monitor (UPERFECT Gravity Sensor 4K Portable Monitor Touchscreen 15.6") works (almost) perfectly. My Macbook Pro 16 recognized it immediately. My iPad Pro works with it even without connecting the monitor to a power outlet. My smartphone is OnePlus 7pro works with it, but needs a power socket. In the box there is a monitor, 2x USB-C cables, 1x USB-A to USB-C cable, 1x mini-HDMI-HDMI cable, 45W wall adapter and a screen Regarding the screen the colors look great the device doesn't get warm just a nice slightly warm comfortable temp i love the touch screen menu and the touch menu in general there are a lot of settings compared to other portable monitors i've had on the screen seems bright at best High settings Enough for my eyes I never crank my monitors to full power anyway Hinge design feels good Hinge tension stays on after many uses tight. Overall, the build quality seems to be very good. PROBLEM: My only problem, and it's probably because my device or panel works "almost perfectly" as mentioned above, is that I sometimes get a few black horizontal lines on my portable monitor. Not sure what it is. It's like a flickering horizontal line that's 1 pixel high but doesn't take up the full width of the screen. It randomly appears as a frame. I get this on all my devices. You would probably miss it if you weren't looking for it. Even after I plugged it in, I still get it. Could it be the eco mode? If UPERFECT can help me with this problem that would be great. Otherwise I had no further problems. I would RECOMMEND this monitor if your budget allows. UPDATE: Received a replacement and there was no black flickering on the new monitor. So my first one just broke.
