How to use your TV as a PC monitor in 3 simple steps (and without buying anything)
↗
A ZDNET how-to covers connecting a TV to a PC or laptop as a primary, secondary, or backup monitor using HDMI cables, cheap adapters, or wireless casting, with setup instructions for Windows, Mac, ChromeOS, and Linux.
For engineers needing an extra display without buying a dedicated monitor, this guide lays out the tradeoffs of each connection method. Wireless options introduce input lag and resolution compression, while adapter-based HDMI connections lose the high-speed data transfer of native DisplayPort or Thunderbolt. The piece is a single-source how-to with no independent corroboration.

The simplest method is a direct HDMI cable connection between PC and TV, which mirrors the desktop with minimal setup.
USB-C-to-HDMI or DisplayPort-to-HDMI adapters cost around $10-15 but do not match the data transfer speeds of native DisplayPort or Thunderbolt connections.
Wireless casting via AirPlay or Googlecast may cause significant input lag and resolution issues due to compression and transmission overhead.
