Launched in the year 2022, the 65UQ7570PUJ is a 65" 4K TV from LG. It comes with a True 8-bit IPS panel. It can achieve a maximum resolution of 3840 x 2160 @ 60 Hz with a pixel density of 68 ppi.
After screen size and resolution, the next important specification of a display that defines 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.
Now, since the TV features a big 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 will be Lifelike! It will produce accurate colors by default.
Understanding the Color Gamut Specification
Color gamut specification of a display is the measurement of the range of colors that the display can show.
A display with poor color reproduction will produce undersaturated/washed out colors that will spoil the immersion.
It is specified in different units - sRGB,sRGB (standard RGB), NTSC 1953, DCI P3 to name a few. It is upto the manufacturer which one they choose.
But you don't need to worry about that, here is a chart that will help you choosing a TV with good color accuracy.
After color gamut, you should look at the static contrast specification as it influences the picture quality substantially.
What is Static Contrast ratio ?
There are two types of contrast specifications for a TV. Static and Dynamic. We are interested in static contrast ratio as dynamic doesn't matter much.
Static contrast tells the intensity of black levels. That is, a TV with static contrast ratio less than 1000:1 may produce black images something like this:
Moreover, such TVs are also prone backlight bleeds that will affect your experience — as shown below.The image is an example of another display, it is not this one
Also, 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.
If given a choice, I will prefer a FHD TV with high contrast ratio over a 4K TV with low contrast ratio.
There is no mention of this specification in the TV's official specsheet. Once again we have to make an assumption based on the TV's other specs. In general, IPS panels come with a static contrast ratio between 700:1 - 1500:1. Considering its a 4K TV, we can assume the ratio of LG 65UQ7570PUJ to be atleast 1200:1 or above.
HDR is also supported on this TV in form of HLG (Hybrid Log Gamma) and HDR10.
As for brightness, the peak brightness the TV can achieve is 250 nits, powered by Direct LED backlight technology.
If you are planning to use the TV other than watching videos — say as a PC monitor or Gaming, you should take a TV that features the lowest input lag. For gaming, both input lag and response time affects the performance.
Unfortunately, there is no specification for input lag on this TV. But as this is not a cheap TV from LG, we can expect an input lag of less than 20ms.
What is Input Lag and Why it matters ?
This lag is the amount of time at which device inputs changes the content of the screen. Though, this won't matter much if you aren't into competitive/FPS games like call of duty.
But ideally, get a TV that has an input lag and response time of < 20ms.
Dimensions and Ergonomics
The width of this TV is 57.13 inches while its height is 35.35 inches.
It is just 2.86 inches thick. It weighs approximately 16.7 kilograms and an additional 0.1 kgs if you include stand.
Coming to ergonomics — If you plan to wall mount the TV, you can make use of the VESA mount provided with this TV, which by the way has an interface size of 400 x 300 mm. Swivel, Tilt or Pivot features are not supported on this unit.
Hardware and Audio
The TV is powered by 4-Core CPU. However, LG didn't provide any information on the RAM on the TV's specsheet.
The Operating System on this TV is webOS 22.
For display connectivity, LG has provided two HDMI 2.0 ports on this TV.
To connect USB devices, it includes one USB 2.0 port. Other connectivity ports include — 1x Cable/Antenna In (F-type female), 1x RS232 (C) and 1x Ethernet RJ45.
Regarding wireless connections, you will have — Wi-Fi (5Ghz + 2.5Ghz), Wifi-Direct, Bluetooth 5.0 and DLNA.
Speaking of speakers, it is packaged with 2 x 10W built-in speakers.
Speaking of power consumption, this TV uses 228.8 Watts on average and 0.5 Watts on standby.
For powering this unit, you'll need either a 110V or 220V outlet @ 50Hz-60Hz.
