Launched in the year 2021, the 50HAK5350 is a 50" 4K TV from Hitachi. It features a 10-bit VA panel.
The max. resolution it can achieve is 3840 x 2160 @ 60 Hz with a pixel density of 89 ppi.
Picture Quality
After screen size and resolution, the very next feature of a display that impacts picture quality is its Color Gamut.
Hitachi did not provide a color gamut specification for this TV. But don't worry, we have other means to guess that.
Considering the TV features a big 50 inch screen, it won't come with a cheap panel, so here we can assume its equivalent sRGB coverage to be 90-100% or above. The color accuracy on this TV will be Lifelike! Meaning it is capable of producing color accurate images.
Understanding the Color Gamut Specification
Color gamut spec of a display indicates the range of colors that the display can display.
A TV with poor color accuracy will produce washed out colors that will spoil the immersion.
It is specified in different units - sRGB,sRGB (standard RGB), NTSC 1953, DCI P3 to name a few. It is upto the manufacturer which one they choose.
But don't worry, below is a chart that will help you choosing a TV with good color accuracy.
After color gamut, the static contrast of a TV similarly impacts its picture quality.
Understanding Static Contrast
There are 2 types of contrast specifications for a TV. Static and Dynamic. We are interested in static contrast ratio as dynamic doesn't matter much.
This tells the intensity of black levels. That is, a TV with static contrast ratio less than 1000:1 may produce black images something like this:

Note that, such TVs are also prone backlight bleeds that will rob your experience — as shown below.

Note that, static contrast ratio and resolution go hand in hand when it comes to details. To put it into perspective, a TV with low contrast ratio will show both dark gray and black as black, thus lesser detail overall.
This TV comes with a static contrast ratio of 8000:1., good enough to produce deep blacks. For the record, it also comes with local dimming feature which is a plus.
HLG (Hybrid Log Gamma), HDR, HDR10 and Dolby Vision are also supported on this TV, so that's a plus.
As for brightness, it can go as bright as 350 nits. The backlight of this TV is powered by Direct LED technology.
Gaming Performance
Now if you are going to use the TV other than watching videos — say as a PC monitor or for gaming purposes, make sure to take a TV with lowest input lag. For gaming, both input lag and response time impacts the performance.
Sadly, we cannot find the input lag specification for this unit. Now, since this is not a cheap TV from Hitachi, we can expect an input lag of less than 20ms.
What is Input Lag and Why it matters ?
This lag is the amount of time at which your key-presses or mouse movements changes the content of your TV. For casual Non-FPS games, input lag doesn't matter much.
Although for better experience, look for a TV that has an input lag and response time of < 20ms.
Dimensions and Ergonomics
The vertical and horizontal measurements of this TV are 44.49 inches and 27.2 inches respectively. It is 3.23 inches thick. It weighs around 8.2 kgs, another 1.8 kgs including stand.
Now, speaking of ergonomics — VESA mount is supported on this TV with an interface size of 200 x 200 mm. Swivel, Tilt or Pivot features are not supported on this unit.
