More and more new Vizio TVs now offer built-in USB drive for you to play local video or music store on it, however, a lot of user complain that they fall into the trouble to play downloaded and backuped files on Vizio Smart TVs, 4K HDR TVs & QLED TVs from USB?just as the condition listed below:
"Vizio Smart TV USB Flash Drive Not Working. The TV is Vizio V-Series 4K TV (V655-J04). Seems like a fine television but issues trying to play anything through a USB port. I have tried putting a movie file onto a USB flash drive and placing it into one of the 3 USB slots but I can't even find a way to see the files in them. I go to devices but they dont show up there, and I look at the inputs but it doesnt list the USB ports. So no idea how I can actually it to play a movie from one. I have tried 4 different usb keys but it makes no difference. What am I doing wrong? Why my Vizio TV does not recognize USB drive? I'm sure this is supposed to be possible."
That's a common question asked on many forums, it appears to happen to a lot of Vizio users, yet the debates on Vizio USB video format have never seemed to come to a conclusion. I figure it could be boiled down to the fact that each model may vary in its ability to decode different video files. You have to go through User Manuals carefully.
Note: Not all external hard drives will work properly when connected to a TV's USB port.
Vizio TV not playing videos from USB? If you have lots of MKV, MOV, MP4, AVI, WMV movies and a Vizio TV, chances are you want to play these vidoes on Vizio TV from a USB. When you try to do this, you'll find you may be able to do this, but may be unable to. These file formats seems one of Vizio TV supported native format according to Vizio's official site. So what's the matter? Don't worry! This article will figure out why your Vizio TV not playing video files and how to watch any formats on Vizio TV easily. First, we need to know what format will Vizio TV play on USB?
If a USB device connected to the Vizio TV is not recognized, the list of files on the device is corrupted or a file in the list is not played, please connect the USB device to a PC, format the device and check the connection. QLED and SUHD TVs support FAT, exFAT, and NTFS file systems".
If there is no problem with your USB drive, you urgently need to solve the format compatibility problem. The video formats supported by each model of Vizio TV differ from other models. It is hard to generalize. A video format is just a video container, which can be encoded with a wide range of codecs. While Vizio TV has poor compatibility with some of the codecs, which will make the video format not playing on TV. For example, your Vizio TV supports MP4 format playback, but it cannot read MP4 encoded by H.265 codec; You can play some 1080P MKV videos on Vizio TV, but your Vizio TV can't recognize 4K DTS MKV files. So for playing all video formats on Vizio TV, you need to convert your video to Vizio TV supported codecs and formats. After a lot of online searching and testing, we find that Vizio HD TV only supports to play file formats encoded with H.264 video codec and AAC audio codec. As for Vizio 4K TV, only MKV container format with H.265/HEVC video encoding are supported.
Acrok Video Converter Ultimate is an excellent Vizio tv converter, which can easily convert and compress problematic MP4, MKV, MOV, AVI, VOB, TiVo, WMV, MTS/M2TS etc. to Vizio TV compatible video files with fast encoding speed and excellent output quality. Codec correction (or conversion) is just the tip of the iceberg that it can handle. In terms of the compute-intensive 4K files, it's also a decent performer, letting you downscale 4K to 1080p, lower 60FPS to 30FPS, adjust bit rate, etc. to better suit your computer hardware configurations and to ensure a flawless video playback or streaming.
