The 50HAL7351 is a 50 inch 4K TV from Hitachi, launched in the year 2021. It comes with a 10-bit VA panel. It can display a maximum resolution of 3840 x 2160 with a refresh rate of 60 Hz and pixel density of 89 ppi.
Picture Quality
After screen size and resolution, the next most important feature to look for in a display is its Color Reproduction (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 50 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 quality on this TV will be Lifelike! It is capable of producing color accurate images.
What Color Gamut means ?
Color gamut spec of a display indicates the range of colors that it can display.
Put Simply, this specification indicates the ability of a TV to produce accurate colors. A TV with low color gamut coverage will miss out on some colors (such as deep red), the result would be a "washed out" picture quality.
Different manufacturers use different measurement standards to define color gamut. Viz — sRGB (most popular), 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.
Now, after color gamut, the static contrast specification of a TV holds almost equal role in picture quality.
The importance of static contrast ratio
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 TVs are likely to suffer from backlight bleeds such as this:
The image is an example of another display, it is not this oneObviously this will rob your viewing experience considerably, especially in a dark room.
Like resolution, the static contrast ratio is also equally responsible for details. To put it into perspective, a TV with low contrast ratio will produce less shades of colors, thus lesser detail overall.
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 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, it can go as bright as 350 nits. The backlight used on the panel is Direct LED.
Gaming Performance
Now if you are planning to use your TV other than using it as a TV — say as a PC monitor or Gaming, you should get a TV that features the lowest input lag. For gaming however, both the input lag and response time impacts the performance.
Unfortunately, we cannot find the input lag specification for this unit. Now, as this is not a cheap TV from Hitachi, 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 your key-presses/mouse movements changes the content of the TV. Though, this won't matter much if you aren't into competitive/FPS games like call of duty.
But ideally, look for a TV that comes with an input lag and response time of less than 20ms.
Dimensions and Ergonomics
The width of this TV is 44 inches while its height is 27.24 inches.
It is 2.68 inches thick. In total, it weighs 11.2 kgs. 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 chipset of this TV is powered by a 4-Core CPU. However, we could'nt find any specification about the total available RAM on the TV's specsheet.
The Operating System on this TV is Android TV.
