The 50UQ7570PUJ is a 50 inch 4K TV from LG, launched in the year 2022. It comes with a True 8-bit VA panel. It can achieve a max resolution of 3840 x 2160 @ 60 Hz with a pixel density of 89 ppi.
After screen size and resolution, the next important spec of a display that defines picture quality is Color Gamut.
This TV doesn't provide 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 will be Lifelike! Meaning it is capable of producing color accurate images AS IT IS intended.
What is Color gamut ?
Color gamut specification of a TV is the measurement of the range of colors that it can produce.
A TV with poor color accuracy will produce undersaturated/washed out colors that will not be pretty to look at.
Different manufacturers use different measurement standards to define color gamut. Viz — sRGB (most popular), NTSC, DCI P3 to name a few.
But don't worry, below is a chart that you can use to choose a TV with good color accuracy.
After color gamut, the static contrast of a TV also impacts its picture quality.
Understanding the static contrast ratio of a TV
There are 2 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 will produce black images something like this:
Moreover, such TVs may suffer from backlight bleeds that will impact your experience — as shown below.The image is an example of another display, it is not this one
Also note, 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, so lesser detail overall.
There is no mention of this spec in the TV's official specsheet. Again we have to take a guess based on the TV's other specifications. The static contrast ratio of this TV would be surely atleast 3000:1. the static contrast ratios of VA panels range between 3000:1 - 8000:1.
HDR is also supported on this TV in form of HLG (Hybrid Log Gamma) and HDR10.
Coming to brightness, the peak brightness the LG 50UQ7570PUJ can produce is 250 nits. The backlight used on the panel is Direct LED.
Now if you are planning to use your TV other than watching videos — like as a PC monitor or for gaming purposes, make sure to take a TV with lowest input lag. For gaming, both input lag and response time impacts the performance.
Sadly, LG did not specify the input lag on this unit. Now, as this is not a cheap TV from LG, we can expect an input lag of less than 20ms.
What is Input lag ?
This lag is the latency at which your device inputs changes the content of the screen. 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.
Dimensions and Ergonomics
The vertical and horizontal measurements of this TV are 44 inches and 27.83 inches respectively. In terms of thickness, it is just 2.86 inches thick. Overall the TV weighs approximately 9.5 KGs including stand. Without stand, it weighs 9.4 Kilograms.
Coming to ergonomics — VESA mount is supported on this TV with an interface size of 200 x 200 mm. Swivel, Tilt or Pivot features are not supported on this unit.
Hardware and Audio
The internals of this TV is powered by Quad Core CPU. However, we could'nt find any specification on the total available RAM on the TV's official specsheet.
The Operating System on this TV is webOS 22.
For display connectivity, there are two HDMI 2.0 ports on this TV.
To connect USB devices, you will have one USB 2.0 port. Other connectivity ports include — 1x Cable/Antenna In (F-type female), 1x RS232 (C) and 1x Ethernet RJ45.
For connecting to this TV wirelessly, the manufacturer has provided a 5Ghz Wi-Fi, 2.5 Ghz Wi-Fi, Wifi-Direct, Bluetooth 5.0 and DLNA.
Now, speaking of speakers, LG has provided 2 x 10W speakers on the TV.
Speaking of power usage, the TV consumes 193.6 Watts on average and 0.5 Watts on standby.
Both 110V and 220V lines are supported on this unit.
