Launched in the year 2022, the 65GGU7950B is a 65" 4K TV from Grundig. It comes with a 10-bit IPS panel.
The max. resolution it can display is 3840 x 2160 @ 60 Hz with a pixel density of 68 ppi.
Picture Quality
After screen size and resolution, the next important feature of a display that will impact your viewing experience is Color Gamut.
This TV doesn't come with a color gamut specification, so we have to take a guess.
Considering the TV features a big 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 color accurate images by default.
Understanding Color Gamut
Color gamut spec of a display is a measure of the range of colors that it can produce.
A panel with poor color accuracy will produce undersaturated colors that will spoil the immersion.
Different manufacturers use different units to specify color gamut. Such as — sRGB (most popular), 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 specification of a TV has equally important role in picture quality.
Understanding Static Contrast
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. Moreover, 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 affect your experience, especially in a dark room.
Also, a TV with high constrast ratio allows you to see more details. So, resolution and static contrast ratio go hand in hand in a sense.
Grundig did not specify static contrast specification for this TV. So we have to make an assumption again based on the TV's other specs. Most IPS panels come with a static contrast ratio between 700:1 - 1500:1. Now, for a 4K TV, we can imagine the ratio of Grundig 65GGU7950B would be >= 1200:1.
HDR is also supported on this TV in form of HDR and HLG (Hybrid Log Gamma).
Coming to brightness, it can go as bright as 250 nits. The backlight used on the panel is Direct LED.
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 gaming or use it as a PC monitor, make sure to get a TV that features the lowest input lag and response time.
Sadly, there is no specification for input lag on this TV. Now, since this is not a cheap TV, input lag on this TV could be 20ms or below.
What is Input lag ?
This lag is the amount of time at which your key-presses or mouse movements changes the content of the TV. 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 has an input lag and response time of < 20ms.
