The max. resolution it can display is 3840 x 2160 with a refresh rate of 60 Hz and a pixel density of 76 ppi.
Picture Quality
Now, the very next feature of a display that will impact your viewing experience is Color Gamut.
This TV doesn't provide a color gamut specification, so we have to take a guess. As this TV features amassive 58 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 will be Lifelike! Meaning it is capable of producing color accurate images AS IT IS intended.
Understanding the Color Gamut Specification
Color gamut specification of a TV is the measurement of the range of colors that it can display.
A panel with poor color accuracy will produce undersaturated/washed out colors that will not be pretty to look at.
Different manufacturers use different measurement standards to specify color gamut. Viz — sRGB, NTSC, DCI P3 etc.
But don't worry, below is a chart that will help you choosing a TV with good color accuracy.
Other than color accuracy, the static contrast of a TV also impacts its picture quality.
What is Static Contrast ?
There are two types of contrast specifications for a TV. Static and Dynamic. We are interested in static contrast ratio as dynamic doesn't matter much.
This specification tells the intensity of black levels. That is, a TV with SC ratio < 1000:1 may produce black images something like this:

Moreover, such TVs may suffer from backlight bleeds that will impact your experience — as shown below.

Also, a TV with high constrast ratio enables you to see more details. So, resolution and static contrast ratio go hand in hand in a sense.
This TV comes with a static contrast ratio of 8000:1., well enough to achieve deep blacks and eye-catching visuals. For the record, it also 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.
As for brightness, it is capable of producing a maximum luminance of 350 nits. The backlight of this TV is powered by Direct LED technology.
Gaming Performance
If you are planning to use your TV just for content consumption, you can safely ignore these specifications. But if you are also planning to use the TV for gaming or use it as a PC monitor, you should take a TV that features the lowest input lag and response time.
Unfortunately, Hitachi did not specify the input lag on this unit. Now, since this is not a cheap TV, we can expect an input lag of less than 20ms.
What is Input lag ?
This lag is the latency at which key-presses/mouse movements changes the content of the screen. Though, this won't matter much if you aren't into competitive/FPS games like call of duty.
For best of both worlds, get a TV that features an input lag and response time of less than 20ms.
Ergonomics and Dimensions
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.
The vertical and horizontal measurements of this TV are 51.38 inches and 32 inches respectively. It is just 3.23 inches thick. In total this TV weighs 15.09 Kgs including its stand. Without stand, it weighs 12.5 Kilograms.
