The 43HE4100 is a 43 inch Full HD TV from Hitachi, launched in the year 2021. It features a 10-bit IPS panel.
The max. resolution it can display is 1920 x 1080 with a refresh rate of 60 Hz and a pixel density of 51 ppi.
Picture Quality
After screen size and resolution, the next important feature of a display is its Color Reproduction (defined by its color gamut specification).
Hitachi did not provide a color gamut specification for this TV. So we have to take a guess.
Considering the TV comes with a 10bit IPS panel, we can safely assume its equivalent sRGB coverage to be 100% or above. Undoubtedly The color quality on this TV should be Lifelike!
Understanding the Color Gamut Specification
Color gamut specification of a TV is a measure of the range of colors that the display can display.
A display with poor color reproduction will produce undersaturated colors that will spoil the immersion.
It is specified in different units - sRGB,sRGB (standard RGB), NTSC, DCI P3 etc.
But don't worry, below is a chart that you can use to choose a TV with good color accuracy.
After color gamut, next in the list that will impact your experience is Static Contrast.
The importance of static contrast ratio
The static contrast ratio of a TV corresponds to its Black levels. A TV with low static contrast ratio (<1000:1) will not produce deep blacks. Moreover, such displays often suffer from backlight bleeds such as this:
The image is an example of another display, it is not this oneClearly this will rob your viewing experience, especially in a dark room.
Also, a TV with high constrast ratio lets you to see more details. So, resolution and static contrast ratio go hand in hand.
If given a choice, always prefer a FHD TV with high contrast ratio over a 4K TV with low contrast ratio.
Hitachi did not define static contrast ratio specification for this TV. Again we have to make an assumption based on the TV's other specifications. Most IPS panels come with a static contrast ratio between 700:1 - 1500:1. As for a mid-range Full HD TV, we can guess the ratio of Hitachi 43HE4100 to be >= 1200:1.
HDR and HDR10 are also supported on this TV.
Coming to brightness, it can go as bright as 300 nits. The backlight used on the panel is Direct LED.
Gaming Performance
If you are planning to use your TV other than watching videos — like as a PC monitor or Gaming, you should get a TV that features the lowest input lag. For gaming, both input lag and response time affects the performance.
Sadly, Hitachi did not specify the input lag on this unit. Now, IPS panels in general are infamous for high input lags and response times. So, the input lag on this TV could be 20ms or above. 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 latency at which key-presses/mouse movements changes the content of the screen. For casual Non-FPS games, input lag doesn't matter much.
But ideally, get a TV that has an input lag and response time of less than 20ms.
Ergonomics and Dimensions
Coming to ergonomics — VESA mount is supported on this TV with an interface size of 100 x 100 mm. The unit doesn't come with either Swivel, Tilt or Pivot support.
The vertical and horizontal measurements of this TV are 38.58 inches and 23.58 inches respectively.
It weighs 6.5 kgs, another 1.8 kgs if you include stand.
Hardware and Audio
The Hitachi 43HE4100 comes with a Dual Core CPU. There is no data about the total RAM on the TV's specsheet.
For display connectivity, Hitachi has provided three HDMI 1.4 (ARC; CEC) ports, one D-sub (15-pin) port, one AV Composite In (Video + L/R) port and one AV Component In (YPbPr + L/R) (via D-Sub) port on this TV.
To connect USB devices, you will have one USB 2.0 port. Other connectivity ports include — 1x CI+ 1.4, 1x Satellite In (Main — F-type female), 1x Antenna (RF) (female) and 1x Ethernet RJ45.
For connecting to this TV wirelessly, 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 8W built-in speakers on the TV.
As for power usage, the TV uses 42 watts on average and 0.5 watts on standby.
It supports a power outlet of 220 V - 240 V/50 Hz - 60 Hz.
