ABOUT THIS TV

Hitachi 55HAQ7350 400x400 Image Hitachi 55HAQ7350

The 55HAQ7350 is a 55 inch 4K TV from Hitachi, launched in the year 2021. It features a 10-bit IPS panel.

The maximum 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 important specification of a display that will impact your viewing experience is its Color Gamut.

This TV doesn't come with a color gamut specification, but don't worry, we have other means to guess that. Now, since the TV features amassive 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 accuracy on this TV should be Lifelike! It is capable of producing accurate colors.

What is Color gamut ?

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

A display with poor color accuracy will produce undersaturated/washed out colors that will spoil your immersive experience.

Different manufacturers use different measurement standards to define color gamut. Viz — sRGB (standard RGB), NTSC 1953, DCI P3 to name a few.

But don't worry, here is a chart that you can use to choose a TV with good color accuracy.

Color Gamut Chart

Other than color accuracy, the static contrast ratio of a TV has equally important role in picture quality.

Understanding 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 will look muddy as shown in the below image.

Example of a display with low contrast ratio

As you can imagine, this will impact your experience considerably.

Note that, 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, always 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., good enough to display deep blacks. For the record, it also comes with local dimming 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, it can go as bright as 250 nits. The backlight used on the panel is Direct LED.

Gaming Performance

If you aren't into gaming, you can ignore these specs. 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, we cannot find the input lag specification for this unit. But since this is not a cheap TV, 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 your device inputs changes the content of your TV. Though, this won't matter much if you aren't into competitive/FPS games like call of duty.

For best of both worlds, get a TV that has an input lag and response time of < 20ms.

Ergonomics and Dimensions

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