Why Buying a TV Is More Complicated Than It Looks
Walk into any electronics store and you're faced with a wall of TVs all showing the same vivid demo footage. Back home, in normal lighting, with standard content, many of those sets look very different. Understanding what the specifications actually mean — and which ones matter for your use case — helps you make a decision you won't regret.
Screen Size: Start Here
The right screen size depends on your viewing distance. A general rule: your viewing distance in inches divided by 1.6 gives a comfortable screen size in inches. For example, a 2.5-metre (98-inch) viewing distance suits a screen of roughly 55 inches.
Bigger isn't always better — in a small room, a screen that's too large creates eye strain and picture degradation at close range.
Panel Technology: LED, QLED, and OLED Explained
| Technology | Best For | Weakness |
|---|---|---|
| Standard LED/LCD | Budget buyers, bright rooms | Limited contrast, backlight bleed |
| QLED (Quantum Dot) | Bright rooms, vivid colours, HDR | Still LCD-based, black levels not as deep as OLED |
| OLED | Dark rooms, cinephiles, perfect blacks | Higher price, burn-in risk with static content |
| Mini-LED | Balance of brightness and contrast | Premium pricing, minor halo effect |
Resolution
- Full HD (1080p): Suitable for screens up to 43 inches at normal viewing distances.
- 4K Ultra HD: The current standard for 43 inches and above. Most new content is available in 4K.
- 8K: Barely any native 8K content exists. Not recommended for typical home use yet.
Refresh Rate: 60Hz vs. 120Hz
A 120Hz refresh rate delivers noticeably smoother motion, which matters for sports and gaming. For general TV watching and movies, 60Hz is adequate. Be cautious of marketing terms like "Motion Rate 240" — these often refer to processed frames, not true panel refresh rates. Look for native refresh rate specifications.
Smart TV Platform
Most modern TVs run a smart platform. The most common are:
- Google TV / Android TV: Wide app selection, familiar interface
- Tizen (Samsung): Fast, well-designed, strong app ecosystem
- webOS (LG): Intuitive, good for streaming apps
- Fire TV (Amazon): Prime Video–focused but supports most major apps
If you use a streaming stick or box (Chromecast, Firestick, Apple TV), the built-in smart platform matters less.
HDR Support
HDR (High Dynamic Range) improves contrast and colour when watching compatible content. Look for HDR10 as a baseline. Dolby Vision is the premium format with dynamic metadata for scene-by-scene optimisation. A TV advertised as "HDR compatible" isn't the same as one that actually delivers a good HDR experience — check peak brightness specifications.
Connectivity: Ports to Look For
- At least 3 HDMI ports (ideally HDMI 2.1 for gaming)
- 2 USB ports for media playback
- Optical audio out for soundbar connection
- Ethernet port for stable streaming
Reliability and Repairability
A TV is a long-term purchase. Research the brand's reputation for build quality and the availability of spare parts. Brands with better parts availability (common in established markets) are easier and cheaper to repair if something goes wrong. This is a factor that's rarely mentioned in reviews but significantly affects long-term value.
