4K Screen
Show LED Scroller on a 4k screen — sharp scrolling text on UHD TVs for lobbies, stages, and storefront windows.
A 4k screen gives LED-style text extra clarity when guests stand farther away. Open LED Scroller on a laptop or stick PC connected to the TV, then fullscreen the preview.
Keep messages short and speeds moderate so a 4k screen does not make fast scrolls harder to read. High contrast still matters more than resolution alone.
We do not sell 4K panels — this page helps you use a 4k screen you already have as a bright digital banner.

Frequently Asked Questions
Do I need a special 4k screen mode in the app?
No. The browser scales to your display. Fullscreen on the 4k screen is enough for a clean sign.
Will text look blurry on a 4k screen?
Use larger font sizes and avoid ultra-thin colors. UHD TVs usually look sharp when the source device outputs 4K or a clean 1080p upscale.
Can I use a 4k screen outdoors?
Only if the TV is rated for that environment. For content, prefer high brightness and slower scrolls.
