Launched in the year 2022, the 75UQ7590PUB is a 75" 4K TV from LG. It comes with a True 8-bit IPS panel.
It can display a max resolution of 3840 x 2160 with a refresh rate of 60 Hz and pixel density of 59 ppi.
Picture Quality
After screen size and resolution, the next most important spec to look for in a display is its Color Reproduction Accuracy (defined by its color gamut specification).
LG has not provided a color gamut specification for this TV. But don't worry, we have other means to guess that.
As this TV features a big 75 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 is capable of producing accurate colors out of the box.
What Color Gamut means ?
Color gamut spec of a display is the measurement of the range of colors that the display can produce.
Put Simply, this specification tells the ability of a display to produce accurate colors. A panel with low gamut coverage will miss out on some colors (such as deep red), thus producing a "washed out" picture.
It is specified in different units - sRGB,sRGB (standard RGB), NTSC, DCI P3 Adobe RGB, rec.2020. It is upto the manufacturer which one they choose.
But don't worry, here is a chart that you can use to choose a TV with good color accuracy.
Other than color accuracy, the static contrast of a TV also impacts its picture quality.
Understanding Static Contrast
A TV with high enough static contrast ratio will produce natural deep blacks while a TV with low contrast ratio (<1000:1) will produce images that may look dusty as shown in the below image.
As you can imagine, this will rob your experience considerably.
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.
LG did not list a static contrast ratio specification for this TV. Again we have to take a guess. FYI — IPS panels come with a static contrast ratio between 700:1 - 1500:1. Now, for a 4K TV, we can guess the ratio to be >= 1200:1.
HDR is also supported on this TV in form of HDR10 Pro and HLG (Hybrid Log Gamma).
As for brightness, it can go as bright as 250 nits. The backlight used on the panel is Direct LED.
Gaming Performance
If you are not planning to game on this TV, you can ignore these specs. 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 with the lowest input lag and response time.
Unfortunately, we cannot find the input lag specification for this unit. But since this is not a cheap TV from LG, input lag on this TV could be 20ms or below.
What is Input Lag and Why it matters ?
This lag is the amount of time at which inputs changes the content of your TV. For casual Non-FPS games, input lag doesn't matter much.
Although for better experience, look for a TV that has an input lag and response time of less than 20ms.
Ergonomics and Dimensions
Speaking of 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 400 mm. There is no Swivel, Tilt or Pivot feature support in this TV.
Vertically, the TV measures 75 inches and horizontally 66.1 inches.
It is 2.4 inches thick.
In total it weighs 31.8 kgs (including stand). Without stand, it weighs 31.4 KGs.

For connecting 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.
For wireless connections on this TV, you will have — Wi-Fi (5Ghz + 2.5Ghz), Wifi-Direct, Bluetooth 5.0 and DLNA.
Coming to audio, LG has provided 2 x 10W speakers on the 75UQ7590PUB.
