The 50GGU7900B is a 50 inch 4K TV from Grundig. It was launched in 2022. It features a 10-bit VA panel.
The max. resolution it can achieve is 3840 x 2160 with a refresh rate of 60 Hz and a pixel density of 89 ppi.
Picture Quality
After screen size and resolution, the next important specification to look for in a display is its Color Reproduction Accuracy, which is defined by its color gamut specification.
Grundig has not provided a color gamut rating for this TV. So we have to take a guess.
Considering the TV features a big 50 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! It is capable of producing color accurate images.
What Color Gamut means ?
Color gamut spec of a display is the measurement of the range of colors that the TV can produce.
In layman terms, it tells the ability of a display to produce accurate colors. A panel with low gamut coverage will miss out on some colors (such as deep red), thus producing a "washed out" picture.
It is specified in different units - sRGB,sRGB (standard RGB), NTSC, 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, the static contrast specification of a TV holds almost equal role in picture quality.
What is Static Contrast ratio ?
A TV with low static contrast ratio will not produce deep enough blacks and can bleed backlight as shown below:
The image is an example of another display, it is not this oneThe static contrast ratio of above TV is rated 800:1. So make sure you get a TV with a static contrast of >= 1000:1. More the better.
Like resolution, the static contrast ratio is also equally responsible for details. To put it into perspective, a TV with low contrast ratio will produce less shades of colors, so lesser detail overall.
Grundig did not state a static contrast ratio specification for this TV. Once again we have to make an assumption based on the TV's other specifications. The static contrast ratio of this TV would be surely atleast 3000:1. the static contrast ratios of VA panels range between 3000:1 - 8000:1.
HDR and HLG (Hybrid Log Gamma) are also supported on this TV, so that's a plus.
Coming to brightness, the peak luminance the TV can achieve is 250 nits. The backlight of this TV is powered by Direct LED technology.
Gaming Performance
If you are planning to use your TV other than using it as a TV — say as a PC monitor or Gaming, you should take a TV with lowest input lag. For gaming, both the input lag and response time affects the performance.
Sadly, there is no specification for input lag on this TV. But as 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 your device inputs changes the content of your TV. Though, this won't matter much if you aren't into competitive/FPS games like call of duty.
Although for better experience, look for a TV that features an input lag and response time of less than 20ms.
Dimensions and Ergonomics
The TV measures 50 inches vertically and 44.68 inches horizontally. Overall, it weighs approximately 11.2 Kgs.
Coming to ergonomics — VESA mount is supported on this TV with an interface size of 200 x 200 mm. There is no Swivel, Tilt or Pivot feature support in this TV.
Hardware and Audio
