The 50UQ70006LB is a 50 inch 4K TV from LG. It was launched in 2022. It comes with a True 8-bit VA panel.
The maximum resolution it can display is 3840 x 2160 with a refresh rate of 60 Hz and a pixel density of 89 ppi.
After screen size and resolution, the next important spec of a display is its Color Reproduction Accuracy (defined by its color gamut specification).
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. The color accuracy on this TV will be Lifelike! Meaning it is capable of producing accurate colors out of the box.
What Color Gamut means ?
Color gamut specification of a TV is the measurement of the range of colors that the display can show.
A TV with poor color accuracy will produce undersaturated colors that will spoil the immersion.
Different manufacturers use different measurement standards to specify color gamut. Viz — sRGB (standard RGB), NTSC, DCI P3 etc.
But don't worry, below is a chart that will help you choosing a TV with good color accuracy.
Other than color accuracy, the static contrast ratio of a TV holds almost equal role in picture quality.
Understanding the static contrast ratio
Static contrast ratio of a TV corresponds to its Black levels. A Display with low static contrast ratio (less than 1000:1) will not produce deep blacks. Apart from this, such TVs are likely to suffer from backlight bleeds such as below:The image is an example of another display, it is not this one
Obviously this will affect your viewing experience considerably, especially in a dark room.
Also, a TV with high constrast ratio enables you to see more details. So, resolution and static contrast ratio go hand in hand in a sense.
We were not able to find a static contrast ratio specification for this TV. So once again we have to take a guess. VA panels always come with impressive contrast ratios. This TV comes with the same, so the static contrast ratio would be easily atleast 3000:1 or above.
HDR is also supported on this TV in form of HDR10 Pro and HLG (Hybrid Log Gamma).
Coming to brightness, the peak brightness the LG 50UQ70006LB can produce is 250 nits. The panel of this TV is powered by Direct LED backlight.
Now if you are going to use the TV other than using it as a TV — say as a PC monitor or for gaming purposes, you should get a TV with lowest input lag. For gaming, both the input lag and response time affects the performance.
Sadly, LG did not specify the input lag on this unit. But as this is not a cheap TV from LG, input lag on this TV could be 20ms or below.
Understanding Input lag and response time
This lag is the amount of time at which inputs 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, get a TV that has an input lag and response time of < 20ms.
Ergonomics and Dimensions
Speaking of ergonomics — a VESA mount with interface size of 300 x 300 mm is provided for wall-mounting. The unit doesn't come with either Swivel, Tilt or Pivot support.
Vertically, the TV measures 50 inches and horizontally 44.17 inches.
In terms of thickness, it is 3.54 inches thick. It weighs around 9.5 kgs and an additional 0.2 kgs if you include stand.
