ABOUT THIS TV

Grundig 50GGU7900A 400x400 Image Grundig 50GGU7900A

The 50GGU7900A is a 50 inch 4K TV from Grundig, launched in the year 2022. It features a 10-bit VA panel.

The maximum resolution it can display 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 most important feature of a display is its Color Reproduction Accuracy, which is defined by its color gamut specification.

This TV doesn't come with a color gamut specification, so we have to make an assumption based on its panel type. Now, since the TV features a 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 quality on this TV should be Lifelike! Meaning it is capable of producing accurate colors.

Understanding Color Gamut

Color gamut spec of a display is the measurement of the range of colors that it can produce.

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), the result would be a "washed out" picture quality.

Different manufacturers use different units to define color gamut. Viz — sRGB, NTSC 1953, DCI P3 Adobe RGB and rec.2020.

But you don't need to worry about that, here is a chart that will help you choosing a TV with good color accuracy.

Color Gamut Chart

After color gamut, the static contrast of a TV similarly impacts its picture quality.

Understanding Static Contrast

There are two types of contrast specifications for a TV. Static and Dynamic. We are interested in static contrast ratio. Dynamic doesn't matter much.

Static contrast tells the intensity of black levels. That is, a TV with SC ratio < 1000:1 will produce black images something like this:

Example of a disply with low contrast ratio

Moreover, such TVs are likely be prone to backlight bleeds that will affect your experience — as shown below.

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, 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.

There's no mention of this spec in this TV's official datasheet. Once again we have to make an assumption based on the TV's other specs. The static contrast ratio of this TV would be surely atleast 3000:1. As you know that this TV comes with a VA panel - VA panels always by nature offer high contrast ratios.

HDR and HLG (Hybrid Log Gamma) are also supported on this TV, so that's a plus.

As for brightness, the peak luminance the TV can achieve is 250 nits, powered by Direct LED backlight.

Gaming Performance

If you are not into 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, make sure to take a TV that features the lowest input lag and response time.

Sadly, we cannot find the input lag specification for this unit. But since this is not a cheap TV, input lag on this TV could be 20ms or below.

What is Input Lag and Why it matters ?

This lag is the latency at which your key-presses/mouse movements changes the content of your TV. For casual Non-FPS games, input lag doesn't matter much.

Although for better experience, look for a TV that has an input lag and response time of less than 20ms.

Ergonomics and Dimensions

Speaking of 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.

The TV measures 50 inches vertically and 44.68 inches horizontally. In total, it weighs approximately 11.2 KGs. So plan your space accordingly.

Hardware and Audio

The Grundig 50GGU7900A comes with a 4-Core CPU. There is no mention on the total RAM on this TV.

The Operating System on this TV is Android TV.

For display connectivity, Grundig has provided two HDMI 2.0 ports on this TV.

To connect 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.

For connecting to this TV wirelessly, you will have — Wi-Fi (2.5Ghz only) and Bluetooth.

The Audio unit of this TV is powered by 2 x 10W speakers.

As for power consumption, the TV uses 50.4W on average and 0.45W on standby.

Both 110V and 220V outlets are supported on this unit.
