ByDiffer 4K Ultra HD Digital Media Player, TV MP4 Video Player for USB Drive/Micro SD Card, H.265/HEVC, Digital Signage, Auto Playback, HDMI/AV/Optical Output (Grey)

I've got 2 of these running now. If your wanting a cheap subscription free way to do digital signage this is it. I make my digital signs as videos in Canva and put the video file on a flash drive. Just plug it into this box and it will run it on a loop automatically. Simple, Effective, Affordable.

Was worried about an off brand, but I really like it. Works perfectly!

Think of this device as an old-school iPod that uses your TV for output. It's offline, with no internet connection, so everything needs to be walked to it. While there are many of these devices around, this one has interesting features like two USB ports plus a Micro SD slot, and the ability to install Android APKs like Musicolet, AIMP, and VLC. Download the 32-bit APKs to a flash drive or micro SD, navigate on the home screen to "Files" and open them to install.Sherry from ByDiffer confirmed for me that the operating system is Android 7.1 and that the maximum capacity of the micro SD card is 128GB and can be formatted FAT32, NTFS, or exFAT.Now the bad news.Documentation is poor. The instruction manual is in broken English, and - as always - batteries aren't included for the remote and you'll need 2 AAA batteries to get started. The software isn't well documented either, starting with what version of Android it is running. FWIW, mine is running firmware version 1.1.8, but there's no information on how to update it or modify it.I've also found that aftermarket music apps can start playing while you're using the built-in video player even if the music app was shut down. There's also no screensaver, which is a disappointing step back from the earlier off-line media players.Verdict: at the price, you're not far off from Android boxes that can access the internet. But those are usually loaded with malware so this being offline-only provides some safety. This box best serves low-tech people who want a simple interface, yet like to experiment with apps. It can be very useful for music or digital signage as well.

On paper, I like the features, but as soon as I unboxed, the unit was plagued with either not being seen by my HDMI port (using the included cable) on my new TV or freezing (happens with and without any media plugged in). The UI was written in semi-poor Chinglish and a couple of the menus didn't make sense, most specifically, the mouse icon. The UI graphics looked 90's era in looks of resolution/font, which is surprising since it claims it can output 4k...I expected a more beautiful user experience. The remote, while responsive, felt cheaply made and feel that one hard press of the button could break it. Good attempt, but falls short to being useful or reliable.

I will update this review with more info later, as I fully explore this device.So far, it is working fineI am using it, attached to a TV mounted at the front of my store, to display still images and show video clips or my products and how they are made.It appears to support all common audio files, as well as all common image files and most video files.This TV had previously only been able to do a fixed slideshow of still images from a usb stick. Now it can show or play anything, and has a very functional remote control.

So far it is working great for the digital media I have to play.I have 720,1080 in 264 and 265 mkv.

I needed a media player with optical audio out. The brands I've used Micca and Agptek didn't have what I needed or they were too expensive. Got this one. The manual is in English but impossible to understand. The unit has standby mode so a light is on constantly. Why does it need standby? It looks like there's a way to turn it off totally but I don't understand how. Then there's mouse mode. Why? Worst of all when you plug a USB stick into it, it writes back a few folders on the stick. Why? As I mentioned before I've used a few different models and have never seen this happen. The remote. It has forward and reverse arrows that we've all seen but don't know how to fast forward or reverse a movie when it's playing. Again the manual is poorly written. I wouldn't recommend this to anyone.I dropped my review down to one star. They've contacted me twice but have not/will not answer my questions. Either it doesn't do everything that's in the manual and/or they don't have anyone there that speaks English. And now I see that the price is reduced for Prime Days. My biggest problem about it is that it writes back to your USB memory stick.

Easy to use to upgrade my old TV to fit all media items, including my Nintendo switch, ps4, blu ray player. Pretty straight forward and it is a plug and play type device. Works great, smaller than I thought, so it doesn’t take up much space. Slick design. No speed issues.
