The 32HAK2355 is a 32 inch HD TV from Hitachi. It was launched in 2021. It comes with a True 8-bit IPS panel. The maximum resolution it can display is 1366 x 768 with a refresh rate of 60 Hz and a pixel density of 49 ppi.
After screen size and resolution, the next important feature to look for in a display is its Color Reproduction Accuracy (defined by its color gamut specification).
This TV doesn't come with a color gamut specification, so we have to make an assumption based on its panel type. This unit comes with an IPS panel. These panels are known to produce great colors out of the box. So we can assume that the sRGB coverage (equivalent) on this TV to be 70% or above. For content viewing and gaming, you will not need any better than this anyway. So its good enough.
What is Color gamut ?
Color gamut specification of a TV is a measure of the range of colors that it can display.
In layman terms, it tells the ability of a display to produce accurate colors. A display with low gamut coverage will miss out on some colors (such as deep red), the result would be a "washed out" picture quality.
It is specified in different units - sRGB,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.
Now, after color gamut, the static contrast ratio of a TV has equally important role in picture quality.
What is Static Contrast ratio ?
A TV with low static contrast ratio will not produce deep blacks and possibly can bleed backlight as shown in the below image:The image is an example of another display, it is not this one
The static contrast ratio of above TV is rated 800:1. So make sure you get a TV with a static contrast of >= 1000:1. More is better.
Also, a TV with high constrast ratio allows you to see more details. So, resolution and static contrast ratio go hand in hand in a sense.
This TV is rated with a static contrast ratio of 8000:1., well enough to display 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 HDR10.
Coming to brightness, it is capable of producing a peak brightness of 250 nits. The backlight of this TV is powered by Direct LED technology.
If you are planning to use your TV solely for content consumption, you can safely ignore these specs. But if you are also going to use the TV for playing games or use it as a PC monitor, you should take a TV with the lowest input lag and response time.
Unfortunately, there is no specification for input lag on this TV. Now, IPS panels in general are infamous for high input lags and response times. So, expect the input lag to be above 20ms. Though, there's no concern for playability of casual or Non-FPS games on it.
What is Input Lag and Why it matters ?
This lag is the amount of time 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 has an input lag and response time of less than 20ms.
Dimensions and Ergonomics
The vertical and horizontal measurements of this TV are 28.58 inches and 17.91 inches respectively.
Coming to thickness, it is just 2.99 inches thick.
Overall this TV weighs 4.38 kgs including stand. Without stand, it weighs 3.18 Kgs. So plan your space accordingly.
Now, speaking of ergonomics — VESA mount is supported on this TV with an interface size of 75 x 75 mm. The unit doesn't come with either Swivel, Tilt or Pivot support.
