The 49HK5600 is a 49 inch 4K TV from Hitachi. It was launched in 2021. It comes with a 10-bit IPS panel. The max. resolution it can achieve is 3840 x 2160 with a refresh rate of 60 Hz and a pixel density of 90 ppi.
After screen size and resolution, the next most important spec of a display is its Color Reproduction Accuracy, which is defined by its color gamut specification.
Hitachi has not provided a color gamut rating for this TV. But don't worry, we have other means to guess that.
Now, since the TV features a 49 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 should be Lifelike! Meaning it will produce color accurate images by default.
Understanding Color Gamut
Color gamut spec of a TV indicates the range of colors that it can display.
A TV with poor color accuracy will produce undersaturated colors that will not be pretty to look at.
Different manufacturers use different units to define color gamut. Such as — sRGB, NTSC 1953, DCI P3 Adobe RGB and rec.2020.
But you don't need to worry about that, below is a chart that will help you choosing a TV with good color accuracy.
Now, after color gamut, the static contrast of a TV also impacts its picture quality.
The importance of static contrast ratio
There are 2 types of contrast specifications for a TV. Static and Dynamic. We are interested in static contrast ratio as dynamic doesn't matter much.
Static contrast specification tells the intensity of black levels. That is, a TV with SC ratio < 1000:1 will produce black images something like this:
Apart from this, such TVs are likely to suffer from backlight bleeds that will affect your experience — as shown below.The image is an example of another display, it is not this one
Think of static contrast as another dimension to details — just like resolution. To put it into perspective, a TV with low contrast ratio will produce less shades of colors, thus lesser detail overall.
If given a choice, always prefer a FHD TV with high contrast ratio over a 4K TV with low contrast ratio.
This TV comes with a static contrast ratio of 8000:1., good enough to achieve deep blacks. 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 and HDR10.
Coming to brightness, it is capable of producing a maximum luminance of 250 nits with the help of Direct LED backlight.
Now if you are going to use the TV other than watching videos — say as a PC monitor or Gaming, you would want to take a TV that features the lowest input lag. For gaming however, both the input lag and response time affects the performance.
Unfortunately, there is no specification for input lag on this TV. But since this is not a cheap TV from Hitachi, input lag on this TV could be 20ms or below.
What is Input lag ?
This lag is the amount of time at which inputs changes the content of the screen. For casual Non-FPS games, input lag doesn't matter much.
Although for better experience, look for 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 200 x 200 mm. Swivel, Tilt or Pivot features are not supported on this unit.
Vertically, the TV measures 49 inches and horizontally 43.81 inches. It weighs approximately 7.54 kgs, another 1.8 kgs if you include stand.
