ABOUT THIS TV

Grundig 65GGU7900A 400x400 Image Grundig 65GGU7900A

The 65GGU7900A is a 65 inch 4K TV from Grundig, launched in the year 2022. It comes with a 10-bit IPS panel.

The maximum 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 very next feature of a display that impacts picture quality is Color Gamut.

This TV doesn't come with a color gamut specification, so we have to make an assumption based on its panel type.

As this TV features amassive 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. 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 TV is the measurement of the range of colors that the display 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 units to specify color gamut. Such as — sRGB, NTSC 1953, DCI P3 etc.

But don't worry, below is a chart that you can use to choose a TV with good color accuracy.

Color Gamut Chart

After color gamut, the static contrast specification of a TV has equally important role in picture quality.

Understanding the static contrast ratio

A TV with high enough static contrast ratio will produce natural deep blacks while a TV with low contrast ratio (<1000:1) will produce images that may look dusty as shown in below image.

Example of a display with low contrast ratio

As you see, this will rob your experience considerably.

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, so lesser detail overall.

If given a choice, always prefer a FHD TV with high contrast ratio over a 4K TV with low contrast ratio.

Grundig did not specify static contrast ratio specification for this TV. So we have to make an assumption again based on the TV's other specifications. FYI — 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 65GGU7900A to 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 planning to game on this TV, you can ignore these specifications. But if you are also going to use the TV for playing games or use it as a PC monitor, you should take 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, we can expect an input lag of less than 20ms.

What is Input lag ?

This lag is the amount of time at which your key-presses/mouse movements changes the content of your TV. Though, this won't matter much if you aren't into competitive/FPS games like call of duty.

For best of both worlds, look for a TV that comes with an input lag and response time of less than 20ms.

Ergonomics and Dimensions
