ABOUT THIS TV

Hitachi 55HK5601 400x400 Image Hitachi 55HK5601

The 55HK5601 is a 55 inch 4K TV from Hitachi, launched in the year 2021. It features a 10-bit IPS panel. The max. resolution it can achieve 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 most important specification to look for in a display is its Color Reproduction (defined by its color gamut specification).

Hitachi has not provided a color gamut rating for this TV. So we have to take a guess.

As this TV features a 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 quality on this TV should be Lifelike! It is capable of producing accurate colors AS IT IS intended.

What Color Gamut means ?

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

A TV with poor color reproduction will produce undersaturated colors that will spoil your immersive experience.

Different manufacturers use different units to specify color gamut. Viz — sRGB (standard RGB), NTSC, DCI P3 etc.

But don't worry, here is a chart that will help you choosing a TV with good color accuracy.

Color Gamut Chart

Now, after color gamut, you should look at the static contrast specification as it influences the picture quality the same way.

Understanding the static contrast ratio

A TV with low static contrast ratio will not produce deep blacks and possibly bleed backlight as shown below:

Backlight bleed exampleThe image is an example of another display, it is not this one

The above TV's static contrast is rated 800:1. So make sure you get a TV with a static contrast of >= 1000:1. More is better.

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 display deep blacks. For the record, it also comes with local dimming backlight which is a plus.

HDR is also supported on this TV in form of HLG (Hybrid Log Gamma), HDR and HDR10.

As for brightness, it can go as bright as 250 nits, which is powered by Direct LED backlight.

Gaming Performance

If you are planning to use your TV only for content consumption, you can ignore these specs. But if you are also going to use the TV for playing games or use it as a PC monitor, you would want to take a TV with the lowest input lag and response time.

Unfortunately, Hitachi did not specify the input lag on this unit. Now, as this is not a cheap TV, 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 key-presses/mouse movements changes the content of the TV. 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 features an input lag and response time of less than 20ms.

Dimensions and Ergonomics

The width of this TV is 49 inches while its height is 29.46 inches.

In total this TV weighs approximately 13.9 KGs including its stand. Without stand, it weighs 11.4 Kilograms. So plan your space accordingly.

Now, speaking of ergonomics — If you plan to wall mount the TV, you can make use of the VESA mount provided with this TV, which by the way has an interface size of 200 x 200 mm. The unit doesn't come with either Swivel, Tilt or Pivot support.

Hardware and Audio

The Hitachi 55HK5601 comes with a 4-Core CPU. There is no mention on the total RAM on this TV.

Speaking of OS, the Hitachi 55HK5601 runs Android 10 Operating System.

For display connectivity, there are two HDMI 2.0 (ARC; CEC) ports and one AV Composite In (Video + L/R) port on this TV.

For connecting USB devices, you will have one USB 2.0 port. Other connectivity ports include — 1x Satellite In (Main — F-type female), 1x AV Component In (YPbPr + L/R) (via PC input), 1x Antenna (RF) (female), 1x CI+ 1.4 and 1x Ethernet RJ45.

For connecting to this TV wirelessly, the manufacturer has provided a 5Ghz Wi-Fi, 2.5 Ghz Wi-Fi, Wifi-Direct, Bluetooth and DLNA.

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

Speaking of power usage, it uses 131.2 Watts on average and 0.5 Watts on standby.
