QLED technology delivers image vibrancy like never before. Offering a range of 1 billion colour shades, standard compressed broadcasting content is restored to its original brilliance for a natural and realistic picture, even in brightly lit rooms. The main source of both its strengths and flaws is its brightness. Right out of the gate, you can tell that it’s much brighter than its cheaper 50UK4D63B sibling. 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. In addition, the television is powered by a quad-core processor that ensures fast and smooth performance. It also has built-in Wi-Fi connectivity, which makes it easy to access streaming services and other online content. Features

We’re not talking about brightness levels to rival those of any current premium TVs, of course, be they OLED or LCD. There are numerous mid-range and even lower-mid LCD models out there that can go brighter still, too. But by budget standards, the 50UK4D63DB produces comfortably more light with both full-screen bright HDR images and small HDR highlights than expected. The highlighting holds up even within already bright shots too, adding up to a more consistent and convincing HDR experience than you’d normally ever see at this price point.

The Toshiba UF3D is available in a range of sizes, from 43 to 65 inches, making it suitable for viewing environments. The 50-inch model is popular, providing a large viewing area without being too bulky or expensive. Users can choose the size that best fits their viewing environment and budget. 4K Resolution Of course, there are some downsides to OLED technology - they're somewhat susceptible to screen burn, with images lingering on the screen if they're left on standby for too long. Is a QLED TV worth it? The higher native brightness of the 55QA5D63DB also means it suffers less with clipping (loss of subtle shading and details) in the brightest areas than the 50UK4D63DB. The 55QA5D63DB’s combination of a Quantum Dot colour system (which can deliver cleaner, purer, brighter colours than the usual LCD colour filter approach) and direct LED lighting (where the LEDs sit directly behind the screen rather than around its edges) raise hopes of a better performance level than you’d usually get for so little money.The Toshiba UF3D comes with a remote control that is easy to use and has a streamlined design. It features dedicated buttons for popular streaming services, making it easy to access your favorite content with the touch of a button. The remote control also has a built-in microphone, allowing users to use Alexa’s voice commands without pressing a button. Connectivity Options We recommend using the Low setting of the TV’s motion processing system, as this slightly eases judder without causing unwanted processing side effects or turning films into soap operas. But if you just can’t cope with the idea of using motion processing, the 55QA5D63DB is still pretty easy to watch without it. 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. Gaming controller: If you plan on using your television for gaming, a gaming controller can provide a more comfortable and enjoyable gaming experience.

The One Connect Box is a feature available on some Samsung televisions. This box connects to the tv and houses all of the connections, including HDMI and USB ports. This feature allows for a cleaner and more organized setup, as all cables can be hidden away in the box. This feature is ideal for those who want a neat and tidy home entertainment setup. Accessories The 50UK4D63DB punches above its price with its colour, too, achieving saturation levels we’ve seen TVs costing many times as much fail to achieve. That gives you at least a flavour of the wide colour gamuts that accompany the vast majority of HDR sources. The Toshiba UF3D comes with a standard remote control, but several accessories can enhance your viewing experience. These accessories include:

Bright HDR scenes additionally reveal the benefits of the 55QA5D63DB’s Quantum Dots, as they appear richly saturated, vibrant and intense, yet also surprisingly rich in nuance and shading subtlety for a TV with such a modest price tag. The IPS panel can’t stop contrast suffering quite badly during viewing from an angle, though, giving us one apt final reminder that for all the things the 55QA5D63DB gets right, its problems with contrast are so fundamental during all but the most glaringly bright content that they’re really pretty hard to live with. In fact, we much prefer the pictures of Toshiba’s substantially cheaper 50UK4D63B, proving – not for the first time – that just throwing Quantum Dots at a screen isn’t the guarantee of better picture quality you might expect. At least at the budget end of the TV world.
