Launched in the year 2021, the 65HL7300 is a 65" 4K TV from Hitachi. It comes with a 10-bit IPS panel.
It can achieve a maximum resolution of 3840 x 2160 with a refresh rate of 60 Hz and pixel density of 68 ppi.
Now, the next important spec of a display that impacts picture quality is Color Gamut.
Hitachi did not provide a color gamut specification for this TV. So we have to take a guess. Now, since the TV features a 65 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! Meaning it is capable of producing accurate colors out of the box.
What is Color gamut ?
Color gamut spec of a display is a measure of the range of colors that the TV can show.
Meaning, this specification tells 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), so the image produced will look "washed out" in colors.
Different manufacturers use different measurement standards to define color gamut. Viz — sRGB (most popular), NTSC, DCI P3 etc.
But don't worry, below 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 has equally important role in picture quality.
Understanding the static contrast ratio of a TV
A TV with high enough static contrast ratio will produce deep blacks while a TV with low contrast ratio (<1000:1) will produce images that might look dusty as shown in the below image.
As you can see, this will rob your experience considerably.
Also, 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.
This TV features a static contrast ratio of 8000:1., well enough to achieve deep blacks and eye-catching visuals. The panel comes with local dimming 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 is capable of producing a maximum brightness of 350 nits. The backlight of this TV is powered by Direct LED technology.
If you aren't planning to game on this TV, you can safely ignore these specifications. But if you are also going to use the TV for playing games or use it as a PC monitor, you would want to get a TV with the lowest input lag and response time.
Sadly, there is no specification for input lag on this TV. 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 latency at which key-presses or mouse movements changes the content of your TV. For casual Non-FPS games, input lag doesn't matter much.
For best of both worlds, get a TV that features an input lag and response time of < 20ms.
Ergonomics and Dimensions
Now, coming to ergonomics — VESA mount is supported on this TV with an interface size of 400 x 200 mm. The unit doesn't come with either Swivel, Tilt or Pivot support.
The vertical and horizontal measurements of this TV are 57.2 inches and 34.84 inches respectively. It is 2.83 inches thick. In total it weighs approximately 22.0 Kgs including its stand. Without stand, it weighs 19.5 Kilograms. So plan your space accordingly.
Hardware and Audio

For connecting USB devices, you will have two USB 2.0 ports. Other connectivity ports include — 1x Satellite In (Main — F-type female), 1x CI+ 1.4, 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.
