Should I use my TV as a computer monitor?

In the early days of computing, monitors were just televisions. Then the high-definition revolution happened, and the monitors really stood out. Now we’re back to square one, and we’re spoilt for choice when it comes to large 4K or even 8K TVs with multiple HDMI 2.1 connections that cost less than high-end monitors. Can you replace the monitor with one of the best gaming TVs? More importantly, do you really want it?

The first part of the question is easy to answer: yes, you can use any TV with an HDMI input in place of a computer monitor. If you’re viewing a 4K TV, you’ll need a graphics card with at least an HDMI 2.0 port (HDMI 2.0a or higher for HDR10 displays). This allows 4K and 24-bit color at 60Hz. Newer TVs support HDMI 2.1, which can handle 4K at 120Hz and 8K at 60Hz, provided your computer also supports HDMI 2.1.
