The 70HAL7350 is a 70 inch 4K TV from Hitachi, launched in the year 2021. It comes with a 10-bit VA panel. The max. resolution it can display is 3840 x 2160 @ 60 Hz with a pixel density of 63 ppi.
Now, the next important spec of a display that impacts picture quality is its Color Gamut.
This TV doesn't provide a color gamut specification, so we have to make an assumption based on its panel type.
As this TV features a 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. The color accuracy on this TV will be Lifelike! It will produce color accurate images by default.
What is Color gamut ?
Color gamut specification of a display is a measure of the range of colors that the TV can show.
A display with poor color accuracy will produce washed out colors that will spoil the immersion.
Different manufacturers use different measurement standards to define color gamut. Viz — sRGB (standard RGB), NTSC 1953, DCI P3 etc.
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.
After color gamut, next in the list of important specifications is Static Contrast.
Understanding Static Contrast
Static contrast ratio of a TV corresponds to its Black levels. A Display with low static contrast ratio (<1000:1) will not produce deep blacks. Also, such displays are likely to suffer from backlight bleeds such as this:The image is an example of another display, it is not this one
This will affect your viewing experience considerably, especially in a dark room.
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 features a static contrast ratio of 8000:1., well enough to produce deep blacks and eye-catching visuals. The panel 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.
Coming to brightness, the peak luminance it can achieve is 250 nits. The panel of this TV is powered by Direct LED backlight.
If you are planning to use your TV solely for content consumption, you can safely ignore these specifications. But if you are also planning to use the TV for playing games or use it as a PC monitor, you would want to take a TV that features 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, 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 inputs changes the content of the screen. 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 < 20ms.
Dimensions and Ergonomics
The TV measures 70 inches vertically and 62 inches horizontally. It is just 2.83 inches thick. It weighs around 22.5 Kgs.
Speaking of ergonomics — a VESA mount with interface size of 400 x 200 mm is provided for wall-mounting. The unit doesn't come with either Swivel, Tilt or Pivot support.
Hardware and Audio
The internals of this TV is powered by a 4-Core CPU. There is no mention about the total available RAM on this TV.
The UI on this TV is powered by Android TV Operating System.

To connect 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.
For wireless connections on this TV, you will have — a 5Ghz Wi-Fi, 2.5 Ghz Wi-Fi, Wifi-Direct, Bluetooth and DLNA.
Now, speaking of speakers, Hitachi has provided 2 x 12W speakers on the 70HAL7350.
Now, coming to power usage, this TV uses 182.4 watts on average and 0.5 watts on standby.
It supports a power outlet of 220 V - 240 V/50 Hz - 60 Hz.
