HDMI 2.1 standard identified as critical factor for television purchases

When purchasing a new television, consumers should prioritize the HDMI standard to ensure future compatibility and performance. While manufacturers often highlight screen size, brightness, or price, the HDMI version is a critical detail. The HDMI 2.1 standard is highly recommended as it supports features such as 8K resolution, up to 120 Hz refresh rates, variable refresh rates (VRR), and enhanced audio transmission via eARC. Many budget models may only feature one or two high-performance ports, while others rely on older standards.

As an example of modern specifications, the TCL 65Q6C model features QD-Mini LED technology with 242 local dimming zones and a 144 Hz refresh rate. This model includes four HDMI 2.1 connectors and supports various gaming and cinematic standards, including VRR, ALLM, FreeSync Premium Pro, and Dolby Vision. It also utilizes an ONKYO 2.1-channel sound system with Dolby Atmos support and operates on the Google TV platform.
