How to share a picture from a laptop to a TV via Wi-Fi: all methods + comparison

Do you want to stream a movie, presentation, or game from your laptop screen to a large TV, but don't want to mess with wires? Wireless image transmission via Wi-Fi — a convenient solution, but not always obvious. Depending on the laptop model, operating system, and TV capabilities, different protocols are available: from the built-in Miracast to proprietary solutions like Apple AirPlay or Google Cast.

The main problem is that not all methods are equally stable. For example, DLNA It's suitable for photos and videos, but won't handle games due to high latency, and Miracast may lag when the router signal is weak. In this article, we'll look into All current methods for transferring images from a laptop to a TV via Wi-Fi, including hidden Windows/macOS settings, workarounds for older TV models, and tips for eliminating lag.
