Launched in the year 2021, the 55HK5300 is a 55" 4K TV from Hitachi. It comes with a 10-bit IPS panel.
The maximum resolution it can display is 3840 x 2160 with a refresh rate of 60 Hz and a pixel density of 80 ppi.
Now, the next important feature of a display that defines picture quality is its Color Gamut.
Hitachi did not provide a color gamut rating for this TV. So we have to take a guess. As this TV features amassive 55 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. Undoubtedly The color accuracy on this TV should be Lifelike! It is capable of producing color accurate images.
What is Color gamut ?
Color gamut spec of a display is the measurement of the range of colors that the TV can show.
What this means is, this specification tells the ability of a TV to produce accurate colors. A panel with low gamut coverage will miss out on some colors (such as deep red), so the image produced will look "washed out" in colors.
Different manufacturers use different measurement standards to specify color gamut. Viz — sRGB (most popular), NTSC 1953, DCI P3 to name a few.
But you don't need to worry about that, here is a chart that you can use to choose a TV with good color accuracy.
Now, next in the list that will impact your experience is Static Contrast.
What is Static Contrast ?
The static contrast ratio of a TV corresponds to its Black levels. A TV with low static contrast ratio (<1000:1) will not produce deep blacks. Moreover, such displays are likely to suffer from backlight bleeds such as below:The image is an example of another display, it is not this one
Clearly this will rob your experience considerably, especially in a dark room.
Think of static contrast as another dimension to details — just like resolution. To put it into perspective, a TV with low contrast ratio will produce less shades of colors, thus lesser detail overall.
If given a choice, always prefer a FHD TV with high contrast ratio over a 4K TV with low contrast ratio.
This TV comes with a static contrast ratio of 8000:1., enough to display deep blacks. For the record, it also comes with local dimming technology which is a plus.
HLG (Hybrid Log Gamma), HDR, HDR10 and Dolby Vision are also supported on this TV, so that's a plus.
Coming to brightness, it is can achieve a maximum luminance of 350 nits. The backlight of this TV is powered by Direct LED technology.
Now if you are planning to use your TV other than using it as a TV — say as a PC monitor or for gaming purposes, you should take a TV with lowest input lag. For gaming however, both the input lag and response time impacts the performance.
Unfortunately, Hitachi did not specify the input lag on this unit. Now, since this is not a cheap TV, input lag on this TV could be 20ms or below.
What is Input Lag and Why it matters ?
This lag is the amount of time at which your device inputs changes the content of your display. Though, this won't matter much if you aren't into competitive/FPS games like call of duty.
Although for better experience, look for a TV that comes with an input lag and response time of < 20ms.
Ergonomics and Dimensions
Now, coming to 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.
