ABOUT THIS TV

Hitachi 39HE4100 400x400 Image Hitachi 39HE4100

The 39HE4100 is a 39 inch Full HD TV from Hitachi, launched in the year 2021. It comes with a 10-bit IPS panel.

The max. resolution it can achieve is 1920 x 1080 with a refresh rate of 60 Hz and a pixel density of 57 ppi.

Picture Quality

After screen size and resolution, the next important specification of a display is its Color Reproduction (defined by its color gamut specification).

Hitachi has not provided a color gamut specification for this TV. But don't worry, we have other means to guess that. Considering the TV comes with a 10bit IPS panel, we can safely assume its equivalent sRGB coverage to be 100% or above. The color accuracy on this TV should be Lifelike!

Understanding Color Gamut

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

In layman terms, this specification determines the ability of a display to produce accurate colors. A TV 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, DCI P3 to name a few. It is upto the manufacturer which one they choose.

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

Color Gamut Chart

After color gamut, next in the list that will impact your experience is Static Contrast.

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 might look dusty as shown in the below image.

Example of a display with low contrast ratio

As you imagine, this will affect your experience considerably.

Other than black levels, a TV with high constrast ratio lets you to see more details. So, resolution and static contrast ratio go hand in hand in a sense.

If given a choice, I will prefer a FHD TV with high contrast ratio over a 4K TV with low contrast ratio.

There is no mention of this spec in this TV's official specsheet. So we have to make an assumption again based on the TV's other specifications. Most IPS panels come with a static contrast ratio between 700:1 - 1500:1. Now, for a mid-range Full HD TV, we can assume the ratio of Hitachi 39HE4100 would be atleast 1200:1 or above.

HDR is also supported on this TV in form of HDR and HDR10.

As for brightness, it is can produce a peak luminance of 300 nits. The backlight of this TV is powered by Direct LED technology.

Gaming Performance

If you are not into gaming, you can safely ignore these specifications. But if you are also going to use the TV for gaming or use it as a PC monitor, make sure to take a TV that features the lowest input lag and response time.

Sadly, 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 20ms or above. Though, Non-FPS and casual games should be playable.

What is Input Lag and Why it matters ?

This lag is the latency at which device inputs changes the content of your display. For casual Non-FPS games, input lag doesn't matter much.

Although for better experience, look for a TV that comes with an input lag and response time of < 20ms.

Dimensions and Ergonomics

The width of this TV is 35 inches while its height is 21.62 inches.

In total it weighs approximately 8.58 kgs including stand. Without stand, it weighs 6.78 Kilograms.

Coming to ergonomics — a VESA mount with interface size of 200 x 200 mm is provided for wall-mounting. Swivel, Tilt or Pivot features are not supported on this unit.

Hardware and Audio

The TV comes with a 2-Core CPU. However, we could'nt find any specification about the total RAM on the TV's official specsheet.

For display connectivity, there are 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.

For connecting 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.

Wireless connectivity options on this TV include Wi-Fi (5Ghz + 2.5Ghz), Wifi-Direct, Bluetooth and DLNA.

Now, for audio, it is packaged with 2 x 8W built-in speakers.

Speaking of power consumption, on average, it uses about 49.34 watts. On standby, it takes 0.5 watts.

For powering this unit, you'll require an 220 V - 240 V/50 Hz - 60 Hz outlet.
