How to Choose the Best Small Smart TV?

Understanding the 40-Inch Size Challenge

True 40-inch TVs have become increasingly rare in 2025.

Manufacturers shifted production to 42-43 inch panels due to manufacturing efficiency. This means your “40-inch” search should include these slightly larger sizes.

The difference between 40 and 43 inches is just 3.7 inches diagonally. In practical terms, a 43-inch TV is only 2.5 inches wider than a 40-inch model.

Resolution: Is 4K Worth It for Small TVs?

4K resolution on TVs under 43 inches only matters if you sit closer than 6 feet.

At typical bedroom viewing distances of 8-10 feet, 1080p looks perfectly sharp. Save $100+ by choosing 1080p if you’re primarily watching from bed or across a room.

However, if using as a desktop monitor or gaming display where you sit 3-4 feet away, 4K provides noticeably better text clarity and detail.

Smart Platform Comparison

The smart platform affects your daily TV experience more than picture quality.

Fire TV excels with Alexa integration and Amazon Prime Video. Roku TV offers the most free channels and simplest interface. VIZIO includes built-in Chromecast, while Samsung’s Tizen provides the most apps.

Consider which ecosystems you already use. iPhone users benefit from Apple AirPlay support, while Android users want Google Cast compatibility.

Gaming Features That Actually Matter

Not all “gaming” features provide real benefits for casual players.

Input lag below 20ms makes the biggest difference for responsive gameplay. Variable Refresh Rate (VRR) only matters for PC gaming or newer consoles. HDMI 2.1 is unnecessary unless you own a PS5 or Xbox Series X.

Auto Low Latency Mode (ALLM) automatically switches to game mode when detecting consoles. This convenience feature prevents forgetting to manually enable game mode.

Connectivity and Port Requirements

Count your devices before choosing a TV to avoid constant cable swapping.

Most 40-43 inch TVs include 2-3 HDMI ports. You’ll need one for cable/satellite, one for gaming console, and possibly one for soundbar with ARC. Streaming devices aren’t necessary with smart TVs unless you prefer a specific platform.

Optical audio output matters if you own an older soundbar. Bluetooth connectivity enables wireless headphones for private listening. Ethernet ports provide more stable streaming than WiFi.
