The 70HL7300 is a 70 inch 4K TV from Hitachi, launched in the year 2021. It comes with a 10-bit VA panel. It can display a max resolution of 3840 x 2160 @ 60 Hz with a pixel density of 63 ppi.
After screen size and resolution, the next most important specification to look for in a display is its Color Reproduction Accuracy, which is defined by its color gamut specification.
Hitachi did not provide a color gamut specification for this TV. But don't worry, we have other means to guess that.
As this TV features amassive 70 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 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 it can produce.
A TV with poor color accuracy will produce undersaturated colors that will spoil your immersive experience.
Different manufacturers use different units to specify color gamut. Viz — sRGB (standard RGB), NTSC 1953, DCI P3 etc.
But you don't need to worry about that, below is a chart that you can use to choose a TV with good color accuracy.
After color gamut, the static contrast of a TV similarly impacts its picture quality.
Understanding the static contrast ratio of a TV
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 might look dusty as shown in the below image.
As you imagine, this will impact your experience considerably.
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.
If given a choice, I will prefer a FHD TV with high contrast ratio over a 4K TV with low contrast ratio.
This TV features a static contrast ratio of 8000:1., enough to produce deep blacks and eye-catching visuals. For the record, it also comes with local dimming backlight technology which is a plus.
HDR is also supported on this TV in form of HLG (Hybrid Log Gamma), HDR, HDR10 and Dolby Vision.
As for brightness, the peak brightness the Hitachi 70HL7300 can produce is 250 nits, powered by Direct LED backlight technology.
If you are not planning to game on this TV, you can safely ignore these specifications. But if you are also planning to use the TV for gaming or use it as a PC monitor, make sure to get a TV that features the lowest input lag and response time.
Sadly, Hitachi did not specify the input lag on this unit. But 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 the screen. 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 has an input lag and response time of less than 20ms.
Dimensions and Ergonomics
The TV measures 70 inches vertically and 62 inches horizontally. It is 2.83 inches thick. In total, it weighs approximately 22.5 Kgs.
Coming to ergonomics — VESA mount is supported on this TV with an interface size of 400 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 4-Core CPU. There is no mention on the available RAM on the TV's official specsheet.
For display connectivity, Hitachi has provided three HDMI 2.0 (ARC; CEC) ports on this TV.
For connecting USB devices, it includes two USB 2.0 ports. Other connectivity ports include — 1x Satellite In (Main — F-type female), 1x CI+ 1.4, 1x Antenna (RF) (female) and 1x Ethernet RJ45.
Wireless connectivity options on the Hitachi 70HL7300 include a 5Ghz Wi-Fi, 2.5 Ghz Wi-Fi, Wifi-Direct, Bluetooth and DLNA.
For audio, Hitachi has provided 2 x 12W built-in speakers on the TV.
In terms of power consumption, the TV consumes 150.4W on average and 0.5W on standby.
For powering this unit, you will require an 220 V - 240 V/50 Hz - 60 Hz outlet.
