ABOUT THIS TV

Hitachi 70HAQ7350 400x400 Image Hitachi 70HAQ7350

The 70HAQ7350 is a 70 inch 4K TV from Hitachi. It was launched in 2021. It features a 10-bit VA panel. The maximum resolution it can achieve is 3840 x 2160 with a refresh rate of 60 Hz and a pixel density of 63 ppi.

Picture Quality

Now, the next important specification of a display that defines picture quality is Color Gamut.

This TV doesn't come with a color gamut specification, so we have to take a guess. Considering the 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. The color accuracy on this TV will be Lifelike! It is capable of producing color accurate images by default.

What Color Gamut means ?

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

In layman terms, it tells the ability of a TV to produce accurate colors. A panel with low color gamut coverage will miss out on some colors (such as deep red), thus producing a "washed out" picture.

It is specified in different units - sRGB(most popular), NTSC 1953, DCI P3 to name a few. It is upto the manufacturer which one they choose.

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.

Color Gamut Chart

Other than color accuracy, you should look at the static contrast specification as it influences the picture quality substantially.

What is Static Contrast ?

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

Example of a display with low contrast ratio

As you see, this will rob 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 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 is rated with a static contrast ratio of 8000:1., good enough to achieve deep blacks and eye-catching visuals. For the record, it also comes with local dimming 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, it is can produce a maximum luminance of 250 nits. The backlight used on the panel is Direct LED.

Gaming Performance

If you are going to use your TV other than using it as a TV — like as a PC monitor or Gaming, make sure to get a TV that features the lowest input lag. For gaming however, both the input lag and response time impacts the performance.

Sadly, we cannot find the input lag specification for this unit. Now, as 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 latency at which your inputs changes the content of your TV. For casual Non-FPS games, input lag doesn't matter much.

But ideally, look for a TV that comes with an input lag and response time of < 20ms.

Ergonomics and Dimensions

Coming to ergonomics — VESA mount is supported on this TV with an interface size of 400 x 200 mm. However, there is no Swivel, Tilt or Pivot feature support on this TV.

Vertically, the TV measures 70 inches and horizontally 62 inches.

Coming to thickness, it is 2.83 inches thick. It weighs around 22.5 Kgs. So plan your space accordingly.

Hardware and Audio

The TV is powered by Quad Core CPU. However, we could'nt find any info on the total RAM on the TV's specsheet.

The UI on this TV is powered by Android 10 Operating System.

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

To connect USB devices, you will have 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 70HAQ7350 include a 5Ghz Wi-Fi, 2.5 Ghz Wi-Fi, Wifi-Direct, Bluetooth and DLNA.

Coming to audio, Hitachi has provided 2 x 12W built-in speakers on the TV.
