The 58HK5600 is a 58 inch 4K TV from Hitachi. It was launched in 2021. It features a 10-bit IPS panel. It can display a maximum resolution of 3840 x 2160 with a refresh rate of 60 Hz and pixel density of 76 ppi.
After screen size and resolution, the next important feature to look for in a display is its Color Reproduction, which is defined by its color gamut specification.
This TV doesn't provide a color gamut specification, so we have to make an assumption based on its panel type. Now, since the TV features a big 58 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 should be Lifelike! Meaning it is capable of producing accurate colors out of the box.
Understanding the Color Gamut Specification
Color gamut specification of a TV is the measurement of the range of colors that it can produce.
Put Simply, it indicates the ability of a TV to produce accurate colors. A TV with low 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,sRGB (standard RGB), NTSC, DCI P3 etc. 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.
Other than color accuracy, the static contrast ratio of a TV has equally important role in picture quality.
Understanding Static Contrast
There are two types of contrast specifications for a TV. Static and Dynamic. We are interested in static contrast ratio as dynamic doesn't matter much.
Static contrast defines the intensity of black levels. That is, a TV with SC ratio less than 1000:1 will produce black images something like this:
Apart from this, such TVs are likely be prone to backlight bleeds that will affect your experience — as shown below.The image is an example of another display, it is not this one
Other than black levels, a TV with high constrast ratio lets you to see more details. So, resolution and static contrast ratio go hand in hand.
If given a choice, I will prefer a FHD TV with high contrast ratio over a 4K TV with low contrast ratio.
This TV is rated with a static contrast ratio of 8000:1., enough to display deep blacks. The panel comes with local dimming which is a plus.
HDR is also supported on this TV in form of HLG (Hybrid Log Gamma), HDR and HDR10.
As for brightness, the peak luminance the TV can achieve is 250 nits, which is powered by Direct LED backlight.
If you are not planning to game on this TV, you can ignore these specs. But if you are also planning to use the TV for gaming or use it as a PC monitor, you should get a TV with the lowest input lag and response time.
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.
Understanding Input lag and response time
This lag is the amount of time at which key-presses/mouse movements changes the content of your display. Though, this won't matter much if you aren't into competitive/FPS games like call of duty.
For best of both worlds, look for a TV that features an input lag and response time of < 20ms.
Dimensions and Ergonomics
The TV measures 58 inches vertically and 51.65 inches horizontally.
It weighs approximately 12.13 kgs and 2.5 kgs extra including stand. So plan your space accordingly.
Speaking of ergonomics — a VESA mount with interface size of 200 x 200 mm is provided for wall-mounting. There is no Swivel, Tilt or Pivot feature support in this TV.
Hardware and Audio
The core of Hitachi 58HK5600 is powered by a 4-Core CPU. However, Hitachi didn't provide any info about the total RAM on the TV's official specsheet.
The UI on this TV is powered by Android 10 Operating System.
For display connectivity, Hitachi has provided two HDMI 2.0 (ARC; CEC) ports and one AV Composite In (Video + L/R) port on this TV.
To connect USB devices, it includes 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 wireless connectivity on this TV, the manufacturer has provided a 5Ghz Wi-Fi, 2.5 Ghz Wi-Fi, Wifi-Direct, Bluetooth and DLNA.
Now, speaking of speakers, it is packaged with 2 x 10W built-in speakers.
In terms of power consumption, on average, this TV consumes 112 Watts. On standby, it takes 0.5 Watts.
For powering this unit, you will need an 220 V - 240 V/50 Hz - 60 Hz outlet.
