ABOUT THIS TV

Hitachi 55HK6300 400x400 Image Hitachi 55HK6300

The 55HK6300 is a 55 inch 4K TV from Hitachi. It was launched in 2021. It features a 10-bit IPS panel.

The max. resolution it can display is 3840 x 2160 with a refresh rate of 60 Hz and a pixel density of 80 ppi.

Picture Quality

After screen size and resolution, the next important spec of a display that defines picture quality is its Color Gamut.

Hitachi did not provide a color gamut specification for this TV. So we have to take a guess.

Now, since the TV features a big 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 will produce accurate colors out of the box.

Understanding Color Gamut

Color gamut specification of a TV is the measurement of the range of colors that the display can produce.

Meaning, it tells the ability of a display to produce accurate colors. A panel with low color gamut coverage will miss out on some colors (such as deep red), so the image produced will look "washed out" in colors.

It is specified in different units - sRGB(most popular), NTSC 1953, DCI P3 Adobe RGB, rec.2020.

But don't worry, below is a chart that you can use to choose a TV with good color accuracy.

Color Gamut Chart

After color gamut, you should look at the static contrast specification as it impacts the picture quality substantially.

The importance of static contrast ratio

A TV with high enough static contrast ratio will produce deep blacks while a TV with low contrast ratio (<1000:1) will produce images that will look muddy as shown in below image.

Example of a display with low contrast ratio

As you see, this will impact your experience considerably.

Also note, 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 produce less shades of colors, thus lesser detail overall.

If given a choice, I will 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 achieve deep blacks and eye-catching visuals. For the record, it also comes with local dimming backlight which is a plus.

HDR10, HLG (Hybrid Log Gamma) and Dolby Vision are also supported on this TV, so that's a plus.

Coming to brightness, it can go as bright as 350 nits with the help of Direct LED backlight.

Gaming Performance

If you are planning to use your TV just for content consumption, you can safely ignore these specifications. But if you are also going to use the TV for gaming or use it as a PC monitor, you would want to take a TV that features the lowest input lag and response time.

Sadly, we cannot find the input lag specification for this unit. But 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 key-presses/mouse movements changes the content of the TV. For casual Non-FPS games, input lag doesn't matter much.

Although for better experience, get a TV that features an input lag and response time of < 20ms.

Dimensions and Ergonomics

Vertically, the TV measures 55 inches and horizontally 48.58 inches. It is just 3.23 inches thick.

It weighs 11.24 kgs and 2.5 kgs extra including stand. So plan your space accordingly.

Now, coming to ergonomics — VESA mount is supported on this TV with an interface size of 200 x 200 mm. The unit doesn't come with Swivel, Tilt or Pivot support.

Hardware and Audio

The chipset of this TV is powered by a Quad Core CPU. There is no mention on the RAM on the TV's specsheet.

For display connectivity, there are three HDMI 2.0 (ARC; CEC) ports on this TV.

For connecting USB devices, you will have two USB 2.0 ports. Other connectivity ports include — 1x Satellite In (F-type female), 1x CI+, 1x Antenna (RF) and 1x Ethernet RJ45.

Wireless connectivity options on the Hitachi 55HK6300 include Wi-Fi (5Ghz + 2.5Ghz), Wifi-Direct, Bluetooth and DLNA.

The Audio unit of this TV is powered by 2 x 10W speakers.

Speaking of power consumption, the TV consumes 131.2 Watts on average and 0.5 Watts on standby.

For powering this unit, you'll need an 220 V - 240 V/50 Hz outlet.
