The 43GGU7900A is a 43 inch 4K TV from Grundig. It was launched in 2022. It features a 10-bit IPS panel. It can display a maximum resolution of 3840 x 2160 @ 60 Hz with a pixel density of 103 ppi.
After screen size and resolution, the next important feature to look for in a display is its Color Reproduction, which is defined by its color gamut specification.
Grundig has not provided a color gamut specification for this TV. So we have to take a guess.
As this TV comes with a 10bit IPS panel, we can safely assume its equivalent sRGB coverage to be 100% or above. The color accuracy on this TV should be Lifelike!
Understanding the Color Gamut Specification
Color gamut spec of a display is a measure of the range of colors that the TV can display.
A display 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 define color gamut. Such as — sRGB (most popular), NTSC 1953, DCI P3 to name a few.
But don't worry, below is a chart that will help you choosing a TV with good color accuracy.
Now, after color gamut, the static contrast of a TV also impacts its picture quality.
Understanding Static Contrast
A TV with low static contrast ratio will not produce deep enough blacks and possibly bleed backlight as below:The image is an example of another display, it is not this one
The above TV's static contrast is 800:1. So make sure you get a TV with a static contrast of >= 1000:1. Ofcourse, More the better.
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, I will prefer a FHD TV with high contrast ratio over a 4K TV with low contrast ratio.
However, we were not able to find a static contrast ratio specification for this TV. So once again we have to make an assumption based on the TV's other specs. FYI — IPS panels come with a static contrast ratio between 700:1 - 1500:1. For a 4K TV, we can assume the ratio to be >= 1200:1.
HDR is also supported on this TV in form of HDR and HLG (Hybrid Log Gamma).
Coming to brightness, it is can achieve a peak brightness of 250 nits, powered by Direct LED backlight technology.
If you are planning to use your TV just for content consumption, you can ignore these specs. But if you are also planning to use the TV for playing games or use it as a PC monitor, you would want to take a TV that features the lowest input lag and response time.
Unfortunately, there is no specification for input lag on this TV. Now, as this is not a cheap TV from Grundig, we can expect an input lag of less than 20ms.
Understanding Input lag and response time
This lag is the latency at which key-presses/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.
Although for better experience, get a TV that comes with an input lag and response time of < 20ms.
Dimensions and Ergonomics
Vertically, the TV measures 43 inches and horizontally 38.58 inches. Overall, it weighs 11.2 Kgs.
Coming to ergonomics — VESA mount is supported on this TV with an interface size of 200 x 200 mm. Swivel, Tilt or Pivot features are not supported on this unit.
Hardware and Audio
The Grundig 43GGU7900A comes with a Quad Core CPU. However, we could'nt find any information on the RAM on the TV's specsheet.
To power its UI, the TV runs Android TV Operating System.
For display connectivity, Grundig has provided two HDMI 2.0 ports on this TV.
For connecting USB devices, it includes two USB 2.0 ports. Other connectivity ports include — 1x Satellite In (F-type), 1x Antenna (RF), 1x CI+ 1.3 and 1x Ethernet RJ45.
Wireless connectivity options on the Grundig 43GGU7900A include Wi-Fi (2.5Ghz only) and Bluetooth.
Now, for audio, it is packaged with 2 x 10W speakers.
Now, coming to power usage, the TV uses 49.73W on average and 0.45W on standby.
For powering this unit, you will need either a 110V or 220V outlet @ 50Hz-60Hz.
