Start with the ports, not the picture
It sounds backwards, but the HDMI row decides more about your daily life than the picture rows do. Look for three things:
- How many ports. Count everything you own: streaming box, game console, cable box, disc player, soundbar. If the TV has fewer ports than your devices plus one, you will be swapping cables.
- The version. HDMI 2.0 handles 4K at 60 Hz. HDMI 2.1 adds higher frame rates and features gamers care about. If you do not game, 2.0 is fine.
- Which port has eARC. The port labeled ARC or eARC is the one that sends sound to a soundbar. Knowing how many remain after the soundbar claims its port avoids surprises. The HDMI explainer covers what those labels mean.
The picture rows
Resolution is the easy one: nearly every TV above the smallest sizes is 4K now. It says little on its own.
HDR formats tell you which flavors of high dynamic range the set can show — HDR10 is the baseline; Dolby Vision and HDR10+ are the scene-by-scene upgrades. More formats means more content plays at its best. But read this row together with the next one.
Brightness is the row marketing departments least like to print plainly, and the one that decides whether HDR is visible at all. HDR needs real brightness to produce its highlights. When a spec sheet lists HDR formats but no brightness figure, or buries it, assume the HDR support is "can accept the signal" rather than "will wow you."
Refresh rate — 60 Hz or 120 Hz — is how many times per second the screen redraws. For films and ordinary TV, 60 Hz is entirely fine. The 120 Hz panels matter for gaming and for some sports fans; they are not a picture-quality upgrade by themselves. Beware trade names like "Motion Rate 240": that is processing, not the panel's true refresh rate. The honest number is the one in hertz.
The platform row
The "smart platform" line names the software the TV runs — its apps, menus and updates. This row ages faster than any other. A panel stays good for many years; the software may slow or stop receiving apps sooner. The reassuring fact: a streaming stick or box can replace the platform later for the price of a modest dinner, so this row matters less than the picture and port rows. The stick vs. box vs. built-in explainer goes deeper.
The sound rows
TV speakers are thin because TVs are thin. What you want from the spec sheet is not the speaker wattage — it is the audio outputs: an HDMI eARC port and, as a fallback, an optical output. Those two rows mean any soundbar you buy later will connect. The soundbar outputs explainer compares them.
The quiet rows that still matter
Two rows rarely get attention but cause real annoyance. The dimensions and weight decide whether the set fits your stand or wall mount — check the stand's feet spacing, not just the screen size. And the viewing angle notes, where given, matter in wide rooms where some seats sit far off to the side.
A five-minute reading order
- HDMI ports: count, version, eARC.
- HDR formats and any brightness figure.
- Refresh rate in plain hertz.
- Smart platform name.
- Audio outputs.
If those five rows fit your room and your devices, the remaining thirty rows are mostly fine print. This article is general guidance compiled from TV manufacturers' published specifications; a given model's own spec sheet is the final word on that model.
