I purchased a portable monitor (viewshocker) on Oct 6, 2020, since i was always going on business trips. I used it to mirror my GPS app and looked over my document, but videos are crystal clear. So this might mostly be good for watching videos. the reason i bought this one is its moderate price, and i wanna take a shot. Now, i am glad i made a good choice. "feilitu" are their website(viewshocker) you can check this website, i bought it when it is at a discount.
