The distant is my least favorite facet of the TV largely characteristic as a result of its measurement and smudge-prone keys. There are many buttons, together with a quantity pad, playback and handy shortcuts for Amazon Prime Video, Netflix and Freeview Play, however it may undoubtedly be slimmed down. I discovered myself utilizing the keys within the centre and the shortcuts, so it’d be nice to have a smaller, sleeker possibility with out the quantity pad, for instance.

The buttons have a great grip to them, however the arrow keys had been susceptible to selecting up smudges and fingerprints.

Image high quality 

  • Two of the three TRU Image Engine options are current 
  • The TV helps Dolby Imaginative and prescient, HDR10 and HLG 
  • 4K upscaling leaves one thing to be desired 

The UL21 takes benefit of plenty of TRU Image Engine options, together with TRU Micro Dimming for deeper blacks and higher distinction and TRU Decision for extra refined 4K upscaling. The set lacks the TRU Circulate smoothing tech discovered on different Toshiba TVs, just like the UK31. 

There’s additionally assist for Dolby Imaginative and prescient and Dolby Atmos. The primary boosts the TV’s HDR, alongside HDR10 and HLG, whereas the second claims to supply extra immersive audio, which I’ll increase on within the sound part.

There are 5 image modes to select from when streaming non-Dolby supported content material – Pure, Cinema, Sport, Sports activities and Dynamic. 

My most well-liked setting was Cinema mode, which has a heat high quality to it with deeper reds and extra orange-toned yellows. I additionally discovered Cinema mode toned down the pinks and blues extra outstanding within the default Pure mode, providing a extra coherent set of colors when streaming films and TV reveals. 

Dynamic mode is way nearer to Pure in color, however with much more pumped-up blues, cooler-toned pinks and sharper particulars, which I feel would work greatest for if you wish to give daytime TV a slight increase. Although, I personally want the best way through which the slight heat of Pure brings extra life to characters. 

Transferring on to Dolby Imaginative and prescient-supported content material and Cinema mode is changed with Dolby Imaginative and prescient Darkish and Dolby Imaginative and prescient Vivid. Dolby Imaginative and prescient Vivid is designed for use in rooms with numerous ambient mild, whereas Darkish is greatest suited to rooms which can be extra, nicely, darkish. 

Stranger Issues appears nice in Dolby Imaginative and prescient, with the setting providing even hotter oranges than Cinema mode. I used to be ready to pick ample quantities of element, from the skinny traces adorning Joyce’s corduroy jacket and the wisps of smoke coming from her lips to the person hairs atop Hopper’s head and the creases worrying his brow. 

Eleven’s pores and skin is heat and saturated within the episode, as are the pores and skin tones in an episode of Method 1: Drive to Survive. The result’s a energetic – if a bit orange – look each in direct daylight and within the moodier lighting of Hawkins. 

Persevering with with Drive to Survive, the daring reds of the racers’ jackets stand out, as does the colourful yellow of the Ferrari emblem. The inexperienced grass is on the hotter aspect, however the orange tones bathing the picture distinction nicely with the blue sky, permitting it to pop.

Biking again to Stranger Issues, night-time scenes look significantly menacing with the lights off in Dolby Imaginative and prescient Darkish, although I did want the blacks would go deeper within the shadows. 

One other space I felt may use a lift was distinction. An inspection of the clouds in an episode of Promoting Sundown confirmed they lacked some definition across the edges. All-in-all, whereas I loved the addition of Dolby Imaginative and prescient HDR, I felt the TV may nonetheless profit from deeper blacks and brighter whites. 

Lastly, I revisited an episode of Gilmore Women from 2003 to see how the TV dealt with upscaling with TRU Decision in tow. The colors appeared sensible – the blue sky was very pure and Lorelai and Rory had sufficient pink of their cheeks to appear lifelike. Nonetheless, they weren’t as saturated as these produced by different TVs, such because the Panasonic JX850. 

The picture was additionally over-sharpened, which, in flip, precipitated the picture to lose some element of their faces. Quick-forward to the membership scene within the Women in Bikinis, Boys Doin’ the Twist episode and the Toshiba’s upscaling was dimmer and noisier than the Panasonic, too. Even in Lorelai’s house, the small print within the wall and on her clothes had been tougher to pick.

Sound high quality 

  • Dolby Atmos assist provides the audio a lift 
  • The sound is sharp and detailed 
  • Influence sounds aren’t essentially the most hard-hitting 

Together with Dolby Imaginative and prescient, the UL21 is a TV that advantages from the assistance of Dolby Atmos, an audio characteristic designed to supply a extra immersive and three-dimensional listening expertise. 

To check the sound, I placed on The Hobbit: An Sudden Journey. First off, I discovered that Dolby Atmos provides a barely fuller sound with deeper bass than the TV’s audio system produce with Atmos off. The soundtrack additionally sounds as if it has been given a lift by way of the setting, permitting it to raised compete with the domineering narration. 

Usually talking, the steadiness between the soundtrack, narration and sound results is respectable sufficient. Each small element from the clank of metallic on metallic to the creak of a fence opening to the slightest scratch of pen on paper is sharp and audible, although Bilbo’s narration stays the loudest sound we hear.

Influence sounds might be simpler. Buildings collapse and villages are destroyed with little fanfare from the audio system and the dragon’s roar is overshadowed by the soundtrack and narration, suggesting an absence of steadiness.

That mentioned, the voices within the mid-range are full of element and the bass current within the soundtrack has an honest quantity of weight to it. Like most inexpensive TVs, the highs and lows are one thing that profit from a lift from a soundbar, however I don’t assume this can be a needed buy should you don’t plan on watching many intense motion scenes.
