There does seem to be some support for the ALLM switching feature that can switch TVs into their fast-response Game mode whenever a game source is detected, but this doesn’t work as consistently during our tests as it should. It also has built-in Wi-Fi connectivity, which makes it easy to access streaming services and other online content.

The only issue is that treble effects can sound over prominent, drawing too much attention to themselves and becoming a touch abrasive at high volumes – something that happens in part because the 55QA5D63DB isn’t as generous with its bass as it is with its high frequencies. Helping its HDR performance out is the way the TV retains better black levels despite its brightness than we customarily find on budget TVs. This feature allows for a cleaner and more organized setup, as all cables can be hidden away in the box. All new sets across all four ranges are set to feature the TikTok TV app built-in, allowing you to watch content from your 'For You' and 'Following' feeds on the big screen. Plus, with Chromecast built-in™, you can easily cast your favourite movies, music, and more to your TV.

It’s a real shame, though, that Toshiba has not yet been able to persuade Disney+ or Apple TV to join the 50UK4D63DB’s cause. For example, if the television is mounted on a white wall, it can display an image of the wall, making it less noticeable. It’s worth saying, though, that with many TVs, particularly budget models, the picture performance we find at one screen size often doesn’t apply to all screen sizes in the same range.

Overall, the Toshiba UF3D 50-inch Smart Fire TV is an excellent television that offers advanced features and excellent picture quality.The Toshiba UF3D is a well-designed television with advanced features and excellent picture quality.

This enables it to deliver much more of the brightness, both in small ‘peaks’ and full-screen situations, that high dynamic range content thrives on. There are numerous mid-range and even lower-mid LCD models out there that can go brighter still, too. Its native 4K pictures are crisp and sharp (a touch too much in its Vivid and Standard picture presets, perhaps), and the sharpness doesn’t break down badly when there’s motion in the frame. When it comes to OLED vs QLED, there are a lot of discussions over which is better, with both having their advantages and disadvantages. In fact, content levels are high, especially as Toshiba has also brought on board Freeview Play to cover Android TV’s blind spots when it comes to the catch-up apps for some of the UK’s main terrestrial broadcasters.The 55QA5D63DB’s Android implementation is slightly sluggish at times, and during our time with the set, we’ve experienced a few bugs, such as sudden momentary brightness drops seemingly unrelated to any specific picture setting, and complete losses of sound (and loss of control over the sound) that could only be fixed by fully powering the TV down. The Smart Fire TV functionality provides easy access to streaming services and apps, while the HDR technology provides a more lifelike viewing experience. This is especially true, unexpectedly, with Toshiba’s Cinema preset, which for various other reasons, as we’ll see, is definitely your best all-round option ahead of the default Natural preset.

Users can also adjust the sound mode to suit the type of content being viewed, with methods such as Standard, Music, and Movie. Black levels are the weakest we’ve seen for many a moon, leaving dark scenes looking consistently washed out, greyed over, flat, short of subtle detailing and just totally unconvincing. You can improve things marginally – and we do mean marginally – by tinkering with the Adaptive Luma and Local Contrast controls.If you're looking to save money on a TV, you may want to check out our guide to the best deals on 40-inch TVs.
