FAQ List

Which TV brands is LinkBeam compatible with?

LinkBeam is compatible with mainstream flat-screen smart TVs, including brands such as Hisense, Skyworth, TCL, Sony, Samsung, and Xiaomi. For older TVs from 3–5 years ago, as long as the screen is flat and there is enough space on top to place the device, it is generally usable. We recommend you provide the TV model, and we can help confirm compatibility.
