Picture Quality
After screen size and resolution, the next most important feature to look for in a display is its Color Reproduction, which is defined by its color gamut specification.
This TV doesn't provide a color gamut specification, but don't worry, we have other means to guess that.
Considering the TV features amassive 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 quality on this TV will be Lifelike! It will produce accurate colors by default.
What is Color gamut ?
Color gamut spec of a display indicates the range of colors that the display can display.
A panel with poor color reproduction will produce undersaturated colors that will spoil the immersion.
It is specified in different units - sRGB(most popular), NTSC 1953, DCI P3 to name a few. It is upto the manufacturer which one they choose.
But you don't need to worry about that, below is a chart that will help you choosing a TV with good color accuracy.
After color gamut, you should look at the static contrast specification as it impacts the picture quality substantially.
What is Static Contrast ?
The static contrast ratio of a TV corresponds to its Black levels. A Display with low static contrast ratio (<1000:1) will not produce deep blacks. Also, such TVs may suffer from backlight bleeds such as below:
The image is an example of another display, it is not this oneNeedless to say, this will impact your viewing experience considerably, especially in a dark room.
Also note, static contrast ratio and resolution go hand in hand when it comes to details. To put it into perspective, a TV with low contrast ratio will show both dark gray and black as black, 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 features a static contrast ratio of 8000:1., good enough to achieve deep blacks. The panel comes with local dimming technology which is a plus.
Dolby Vision, HDR10 and HLG (Hybrid Log Gamma) are also supported on this TV.
As for brightness, it is can achieve a maximum brightness of 250 nits. The panel of this TV is powered by Direct LED backlight technology.
Gaming Performance
If you aren't interested in gaming, you can ignore these specs. 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.
Unfortunately, Sony 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 and Why it matters ?
This lag is the amount of time at which your key-presses/mouse movements changes the content of your display. Though, this won't matter much if you aren't into competitive/FPS games like call of duty.
For best of both worlds, look for a TV that has an input lag and response time of less than 20ms.
