Buying a smart TV does not have to be overwhelming. This guide helps you choose the right size, resolution, and features for your room and viewing habits.
📏 1. Choose the right screen size

❓ 10. Frequently Asked Questions
Common Smart TV Questions
Get answers to the most frequently asked questions about screen sizes, resolution, panel types, and smart features.
Q: What size TV should I buy for my 12x15 living room?
A:
50-55" is ideal for a 12x15 room. Measure your viewing distance (couch to TV wall) - if it's 8-10 feet, choose 50-55". If you sit closer (6-8 feet), 43" might be better. The rule is viewing distance should be 1.5-2 times the screen size.
Q: Is 4K worth it or should I stick with Full HD?
A:
Choose 4K for 43"+ TVs, Full HD is fine for 32-40" TVs. Netflix, Prime Video, and YouTube have lots of 4K content now. 4K also future-proofs your purchase. The price difference is minimal for larger TVs.
Q: OLED or QLED - which is better for bright rooms?
A:
QLED is better for bright rooms. QLED TVs get much brighter than OLED, so you will not see reflections or washout during day viewing. OLED is superior for dark rooms with perfect blacks, but struggles with brightness and reflections.
Q: Do I need 120Hz refresh rate if I do not game?
A:
60Hz is sufficient for regular viewing. 120Hz helps with sports and action movies by reducing motion blur, but it's not essential. Save money and choose 60Hz unless you're a serious gamer or sports enthusiast.
Q: Android TV or Fire TV OS - which should I choose?
A:
Android TV for most users. It has more apps, regular updates from Google, and familiar interface. Choose Fire TV OS only if you're heavily invested in Amazon ecosystem and primarily use Prime Video.
Q: How many HDMI ports do I really need?
A:
Minimum 3, ideally 4 HDMI ports. You'll typically need: Set-top box/DTH, gaming console, streaming device (Fire Stick/Chromecast), and maybe a soundbar. Having extra ports avoids frequent cable swapping.
Q: Should I buy a soundbar with my TV?
A:
Not immediately, but plan for it later. Start with TV speakers and see if they meet your needs. Most people find TV speakers insufficient for movies and music. A good soundbar (₹5,000-15,000) dramatically improves the experience.
