The $20 Walmart Onn 4K Google TV box is the best-value digital signage player you can buy. Install the free GuzelBoard app from Google Play, pair it once, and run your screen from your phone. One screen free forever.
Pure Android TV, 2 GB RAM, twenty bucks.
At about $20 from Walmart, the Onn 4K Google TV box is the cheapest capable signage device on the market. Pair it with GuzelBoard's free plan and your first screen costs nothing to run.
The Onn 4K runs near-stock Android TV with 2 GB of RAM. GuzelBoard installs straight from the Google Play Store and runs smoothly — image loops, web dashboards, and Google Slides all work out of the box.
GuzelBoard caches your content on the Onn 4K, so a dropped connection won't blank the screen. It keeps showing the last synced content until the network is back.
Straight from the Google Play Store — no side-loading needed.
Connect the Onn 4K box to your TV's HDMI port and power it on.
Open the Google Play Store, search "GuzelBoard", and install the free app.
Get a pairing code, register on the web panel, and upload your content.
