Picture Quality of Hitachi 50HK6T74U

Hitachi 50HK6T74U

The Hitachi 50HK6T74U is one of the newest offerings from Hitachi from their HK6T74U series of Ultra HD 4K Smart TV. It has a native resolution of 3840 by 2160 pixels a.k.a an Ultra HD 4K.  The TV also uses a direct-lit let screen type as well as a VA display panel. It has a peak panel luminance of 350Cd/M2 and a contrast ratio of 1200/1.

In terms of picture quality, the Hitachi 50HK6T74U exhibits a wonderful color reproduction. It’s probably thanks to its VA panel. Despite having a contrast ratio of 1200/1, VA panels are capable of performing deeper blacks and giving higher contrast ratios of around 2000:1 – 5000:1. That is if you disable the built-in dynamic contrast setting of this TV.

After watching Despicable Me 3, which is a movie that is animated and exhibits a wide range of colour, the Hitachi 50HK6T74U amazed us with its details to colour. Shadows were amazingly detailed without losing much data and the colours are highly accurate. You will not be displeased watching a movie with this TV.

Although, watching in a dark room won’t be much of a problem but watching in a bright room will surely be one. The Hitachi 50HK6T74U has a very low panel luminance rating of 350Cd/M2 only. That is below the average luminance that you can find on most 4K Smart TVs on the market.

Overall, the picture quality is great but don’t expect any miracles. Given its screen size and price point, we were pretty much expecting a compromise in performance. So you better check or test this TV first if you really want to save some money for a decent 4K TV with a 50-inch screen size.


In terms of gaming, this TV has a 50Hz native refresh rate which is already a bummer for gamers. It also has a poor input lag rating that averages 47ms on game mode. So you might want to look for different models if you want a gaming friendly or oriented 4K TV.

Despite the downs for gamers, this TV is rated 6ms response time which is a plus. This is the average or common response time that you will find on most gaming monitors for computers. Meaning, you will not see any ghosting during any fast scene. So that’s something that you might want to also take into consideration if you’re planning to buy this TV.


The audio quality of the Hitachi 50HK6T74U is decent and performs like any other TV. It has 2CH built-in speakers that use 20W of power. The speakers are okay for casual television watching or watching movies in a small room but you might find the need to add a much stronger sound system. Something like a[amsl asin=”B06WVQCG6J” title=”” class=””] TaoTronics Sound System[/amsl]. This soundbar alone already has twice the power of the built-in speakers and a wider range for that satisfying audio quality.

Our Verdict

Overall, the Hitachi 50HK6T74U is a great TV and by far the cheapest one you can find with a 50-Inch screen size. What we like about this TV are its affordability and its price. For less than £500 on Amazon, you can enjoy the goodness of a 4K Smart TV on a 50-inch screen. We also liked its friendly user smart UI that you can explore without any hiccups.

What we did not like about this TV is its low panel luminance for a 4K TV. Well, we should be expecting a compromise in performance to get a 4K TV with the Smart System goodness for an affordable price. We just did not expect it that the brightness or luminance of the display will take a hit because of the price.


  • 6ms Response Time
  • Cheapest 4K TV for 50-Inch
  • Premium Design


  • Poor Input Lag and Low Refresh Rate
