ABOUT THIS TV

Grundig 65GFU7900 400x400 Image Grundig 65GFU7900

The 65GFU7900 is a 65 inch 4K TV from Grundig. It was launched in 2021. 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 68 ppi.

Picture Quality

Now, the very next feature of a display that defines picture quality is Color Gamut.

This TV doesn't provide a color gamut specification, so we have to take a guess.

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 quality on this TV should be Lifelike! Meaning it will produce color accurate images out of the box.

Understanding Color Gamut

Color gamut spec of a TV is the measurement of the range of colors that the display can show.

What this means is, it determines the ability of a TV to produce accurate colors. A display with low color gamut coverage will miss out on some colors (such as deep red), thus producing a "washed out" picture.

Different manufacturers use different units to define color gamut. Such as — sRGB (most popular), NTSC 1953, DCI P3 to name a few.

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.

Color Gamut Chart

After color gamut, the static contrast specification of a TV holds almost equal role in picture quality.

Understanding Static Contrast

A TV with low static contrast ratio will not produce deep blacks and possibly can bleed backlight as in the below image:

Backlight bleed exampleThe 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 produce less shades of colors, thus lesser detail overall.

There's no mention of this spec in the TV's official specsheet. So we have to make an assumption again. Most IPS panels come with a static contrast ratio between 700:1 - 1500:1. Now, for a 4K TV, we can imagine the ratio would be 1200:1 or above.

HDR is also supported on this TV in form of HDR and HLG (Hybrid Log Gamma).

Coming to brightness, the peak luminance it can produce is 250 nits. The backlight of this TV is powered by Direct LED technology.

Gaming Performance

If you aren't into gaming, you can safely ignore these specifications. But if you are also going to use the TV for gaming or use it as a PC monitor, you would want to get a TV that features the lowest input lag and response time.

Sadly, there is no specification for input lag on this TV. But as this is not a cheap TV, input lag on this TV could be 20ms or below.

What is Input lag ?

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

But ideally, look for a TV that comes with 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 400 x 400 mm. The unit doesn't come with either Swivel, Tilt or Pivot support.

The TV measures 65 inches vertically and 57.44 inches horizontally. It is 3.35 inches thick.

In total it weighs 19.35 kgs including stand. Without stand, it weighs 16.85 Kilograms. So plan your space accordingly.
