The 43GGU7900B is a 43 inch 4K TV from Grundig. It was launched in 2022. It comes with a 10-bit IPS panel.
It can achieve a max resolution of 3840 x 2160 with a refresh rate of 60 Hz and pixel density of 103 ppi.
After screen size and resolution, the next important feature to look for in a display is its Color Reproduction (defined by its color gamut specification).
Grundig did not provide a color gamut specification for this TV. But don't worry, we have other means to guess that. Considering the TV comes with a 10bit IPS panel, we can safely assume its equivalent sRGB coverage to be 100% or above. Undoubtedly The color accuracy on this TV should be Lifelike!
Understanding the Color Gamut Specification
Color gamut spec of a display is the measurement of the range of colors that the display can show.
Meaning, this specification tells the ability of a display to produce accurate colors. A display with low gamut coverage will miss out on some colors (such as deep red), so the image produced will look "washed out" in colors.
It is specified in different units - sRGB,sRGB (standard RGB), NTSC 1953, DCI P3 Adobe RGB, rec.2020. It is upto the manufacturer which one they choose.
But you don't need to worry about that, below is a chart that you can use to choose a TV with good color accuracy.
After color gamut, the static contrast specification of a TV has equally important role in picture quality.
Why its important?
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. Apart from this, such TVs may suffer from backlight bleeds such as below:The image is an example of another display, it is not this one
Obviously this will impact your viewing 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.
There is no mention of this specification in the TV's official specsheet. So we have to make an assumption again based on the TV's other specifications. Most IPS panels come with a static contrast ratio between 700:1 - 1500:1. As for a 4K TV, we can imagine the ratio of Grundig 43GGU7900B to be on the upper side, that is atleast 1200:1.
HDR is also supported on this TV in form of HDR and HLG (Hybrid Log Gamma).
As for brightness, the peak brightness the TV can achieve is 250 nits, powered by Direct LED backlight.
If you are not into gaming, you can ignore these specifications. But if you are also planning to use the TV for playing games or use it as a PC monitor, make sure to get a TV that features the lowest input lag and response time.
Sadly, we cannot find the input lag specification for this unit. Now, since this is not a cheap TV from Grundig, input lag on this TV could be 20ms or below.
What is Input lag ?
This lag is the latency at which device inputs changes the content of the TV. For casual Non-FPS games, input lag doesn't matter much.
But ideally, get a TV that features an input lag and response time of less than 20ms.
Ergonomics and Dimensions
Speaking of ergonomics — a VESA mount with interface size of 200 x 200 mm is provided for wall-mounting. However, there is no Swivel, Tilt or Pivot feature support in this TV.
The vertical and horizontal measurements of this TV are 38.58 inches and 23.58 inches respectively. Overall, it weighs around 11.2 Kgs. So plan your space accordingly.
