Buying Guide: What to Look for in a 40-Inch Smart TV

Picture Quality and Resolution

For a 40-inch screen, 1080p Full HD remains the standard, but some models like the TOSHIBA 40″ Class V45 Series QLED FHD 1080p use advanced processing to elevate clarity and color. The TOSHIBA employs the REGZA Engine High Grade to optimize contrast and detail, while the Samsung 43-Inch Class Crystal UHD U8000H Series includes a Crystal Processor for 4K upscaling. Even if you are not watching native 4K content, upscaling can make a noticeable difference. For a deeper look at larger screens with 4K, see our top 75 inch TVs for 2026.

Smart Platform and Streaming Experience

Each TV comes with a different smart ecosystem. The Roku 40-Inch Select Series Smart TV 2026-1080p runs the intuitive Roku TV platform, known for its simple interface and vast free content library. The TOSHIBA integrates Amazon Fire TV with Alexa voice control, giving you access to millions of movies and episodes. The Samsung uses its own Tizen-based system with Samsung TV Plus, which offers thousands of free channels. Consider which platform aligns with your streaming habits.

Audio Performance

Built-in speakers on slim TVs often lack depth, but these models include features to improve sound. The TOSHIBA uses REGZA Power Audio with dual Clear Direct Speakers and DTS Virtual:X for virtual surround. The Roku delivers clear audio suitable for everyday viewing, while the Samsung offers standard stereo sound. If immersive audio matters to you, the TOSHIBA’s DTS Virtual:X is a standout.

Casual gamers will appreciate the TOSHIBA’s Game Mode, which adjusts picture settings for smoother gameplay. The Samsung includes Motion Xcelerator for up to 4K 60Hz performance, reducing blur in fast-paced scenes. The Roku does not emphasize gaming features, but its 1080p resolution is sufficient for most console games. If gaming is a priority, the Samsung offers the best motion handling.
