Review on Neewer F100 7 Inch Camera Field Monitor HD Video Assist with 4K HDMI Input and 1080p Resolution – Includes 2600mAh Li-ion Battery and 11” Magic Arm for DSLR Cameras, Stabilizer, Film Video Making Rig by Chad Boho

I bought this monitor because it has a USB upgrade only to find out it's an old dinosaur connector (USB 2.0) and not a regular USB acts. I wanted a screen that I could run off my power bank because I hate creating content and my battery is dead. My DSLR is powered by the AC adapter and I wanted the screen to do the same, but 🤦🏾‍♂️! I even have USB 2.0 and the screen still won't turn on, it just turns blue. Wasting my time and money. I go back. Everything else is fine, turning the camera on and off the colors get weird, it doesn't really look like 4k anymore than it used to, it's very plasticky and feels brittle. The only great thing about it is that the packaging is nice.
