The OLED77G29LD is a 77 inch 4K TV from LG, launched in the year 2022. It features a True 10-bit OLED evo panel.
The maximum resolution it can display is 3840 x 2160 @ 120 Hz with a pixel density of 57 ppi.
After screen size and resolution, the very next feature of a display that will impact your viewing experience 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.
Now, since the TV comes with an OLED panel, there is no need to worry about color accuracy. Rest assured, OLED panels are excellent at producing accurate colors.
What is Color gamut ?
Color gamut spec of a TV is the measurement of the range of colors that the display can display.
Meaning, it indicates the ability of a TV to produce accurate colors. A TV with low color gamut coverage will miss out on some colors (such as deep red), so the image produced will look "washed out" in colors.
Different manufacturers use different units to specify color gamut. Such as — sRGB, NTSC 1953, DCI P3 to name a few.
But you don't need to worry about that, below is a chart that will help you choosing a TV with good color accuracy.
Now, after color gamut, the static contrast ratio of a TV holds almost equal role in picture quality.
What is Static Contrast ?
Static contrast ratio of a TV corresponds to its Black levels. A TV with low static contrast ratio (less than 1000:1) will not produce deep blacks. Moreover, such displays often suffer from backlight bleeds such as this:The image is an example of another display, it is not this one
Needless to say, this will affect your viewing experience, especially in a dark room.
Also, a TV with high constrast ratio lets you to see more details. So, resolution and static contrast ratio go hand in hand.
If given a choice, always prefer a FHD TV with high contrast ratio over a 4K TV with low contrast ratio.
This TV comes with a static contrast ratio of Infinity:1. That's a plus point of owning an OLED TV. So no need to worry about this.
HDR is also supported on this TV in form of HLG (Hybrid Log Gamma), Dolby Vision, Dolby Vision IQ and HDR10 Pro.
Coming to brightness, the peak brightness the TV can produce is 250 nits.
If you aren't into gaming, you can safely 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 with the lowest input lag and response time.
The input lag on this TV is 5 ms and its minimum response time is 1 ms. Gamers will love this TV.
What is Input lag ?
This lag is the amount of time at which key-presses/mouse movements changes the content of your display. Though, this won't matter much if you aren't into competitive/FPS games like call of duty.
But ideally, look for a TV that has an input lag and response time of < 20ms.
