How to Choose a TV: Types, Key Specs, and Buying Tips

Updated

To choose a TV, decide on three things first: the panel type (LED/LCD, OLED, or QLED), the screen size that fits your viewing distance, and the resolution you actually need (4K is the practical default; 8K only pays off at very large sizes). Then match refresh rate, HDR support, smart platform, and ports to how you'll use it — movies, sports, or gaming. This guide walks through each decision so you can compare models at a retailer like B&H Photo Video with confidence.

Start With Panel Type

The panel determines contrast, black levels, and viewing angle more than almost any other spec.

Panel type How it works Strengths Trade-offs
LED / LCD LED backlight behind an LCD layer Bright, affordable, widely available in large sizes Weaker black levels unless it uses local dimming
QLED LED/LCD with a quantum-dot layer High brightness, strong color volume, good for bright rooms Still relies on backlighting, so contrast trails OLED
OLED Self-emissive pixels, no backlight Perfect blacks, near-infinite contrast, wide viewing angles Typically lower peak brightness than the brightest LED/QLED sets

If you watch in a bright room or want the largest screen for the money, LED or QLED usually makes sense. If you watch in a dim room and care most about contrast and black levels, OLED is the stronger pick.

Match Screen Size to Your Room

Size is the most common regret in TV buying — people usually wish they'd gone bigger. A rough guide based on typical viewing distance:

  • Under 6 ft: 40–50 inches
  • 6–8 ft: 50–65 inches
  • 8–10 ft: 65–75 inches
  • Over 10 ft: 75 inches and up

Measure the wall or stand space first, and confirm the set's dimensions including the stand, not just the screen diagonal. Check that the TV fits your furniture and that you can still reach ports after mounting.

Resolution: 4K Is the Default

  • 1080p (Full HD): Fine for smaller screens and secondary rooms, but increasingly limited in new models.
  • 4K (UHD): The mainstream choice. Native 4K content is widely available, and upscaling of older content is generally good.
  • 8K: Only worth considering at very large sizes where you sit close enough to see the extra detail. Content is still limited, so it's rarely the best use of budget.

Specs That Change Your Experience

HDR format

HDR (high dynamic range) matters more than resolution for perceived picture quality. Look for support for the formats your content uses — commonly HDR10, Dolby Vision, and HLG. A set that supports the format your streaming services and discs use will look better than one that doesn't.

Refresh rate

  • 60Hz: Adequate for most movies and general viewing.
  • 120Hz: Noticeably smoother for sports and a real advantage for gaming, especially with current consoles and PCs.

Smart platform and ports

Check that the built-in smart system carries the apps you use, and count the HDMI inputs you need for a console, soundbar, and streaming device. Confirm the HDMI version supports the features you want (for example, higher refresh rates or variable refresh rate for gaming).

Gaming-specific features

If gaming matters, look for low input lag, variable refresh rate (VRR), and auto low-latency mode (ALLM). These affect feel more than raw picture specs.

Weigh Budget Against Use

  • Movies and general viewing: Prioritize contrast and HDR support; OLED or a well-implemented QLED.
  • Sports: Prioritize brightness and a 120Hz panel to reduce motion blur.
  • Gaming: Prioritize low input lag, VRR, and 120Hz.
  • Bright rooms: Prioritize peak brightness over perfect blacks.

Set a budget and decide which one or two specs matter most to you, then let the rest flex.

Buying at a Retailer Like B&H Photo Video

B&H lists TVs alongside home theater and camera gear, so you can compare models in one place. Before checkout, confirm:

  • Warranty terms — length and what's covered.
  • Delivery and installation — whether the set ships to your door and who handles setup.
  • Return and exchange policy — the window and any conditions.

These policies vary by product and seller, so verify them on the specific listing rather than assuming.

Quick Decision Checklist

  1. Pick panel type based on room brightness and contrast priorities.
  2. Choose size from your actual viewing distance and available space.
  3. Default to 4K unless you have a specific reason for 8K.
  4. Confirm HDR format, refresh rate, smart apps, and port count.
  5. Match gaming features to your console or PC if relevant.
  6. Check warranty, delivery, and returns before buying.
