ABOUT THIS TV

LG OLED48A2PUA 400x400 Image LG OLED48A2PUA

The OLED48A2PUA is a 48 inch 4K TV from LG, launched in the year 2022. It features a True 10-bit OLED panel.

The max. resolution it can achieve is 3840 x 2160 with a refresh rate of 60 Hz and a pixel density of 92 ppi.

Picture Quality

After screen size and resolution, the next most important specification of 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 the TV comes with an OLED panel, so we can conclude that the equivalent sRGB coverage of this panel would be far above 100%.

What Color Gamut means ?

Color gamut specification of a display is the measurement of the range of colors that the display can produce.

In other words, it determines the ability of a TV to produce accurate colors. A panel 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 measurement standards to define color gamut. Viz — sRGB (most popular), 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.

Next in the list that will impact your experience is Static Contrast.

What is Static Contrast ratio ?

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:

Example of a disply with low contrast ratio

Note that, such TVs may suffer from backlight bleeds that will impact your experience — as shown below.

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 show both dark gray and black as black, so 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.

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 at all.

HLG (Hybrid Log Gamma), Dolby Vision, Dolby Vision IQ and HDR10 Pro are also supported on this TV.

As for brightness, the peak brightness it can produce is 250 nits.

Gaming Performance

If you are planning to use your TV only for content consumption, you can ignore these specs. But if you are also planning to use the TV for playing games or use it as a PC monitor, you would want to get a TV with the lowest input lag and response time.

The input lag on the LG OLED48A2PUA is 5 ms and its minimum response time is 1 ms. Gamers gonna love this TV.

Understanding Input lag and response time

This lag is the latency at which your 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 comes with an input lag and response time of less than 20ms.

Dimensions and Ergonomics

The width of this TV is 42.13 inches while its height is 26.93 inches. In terms of thickness, it is just 1.81 inches thick. In total it weighs around 11.7 KGs (including stand). Without stand, it weighs 11.5 KGs. So plan your space accordingly.

Now, coming to ergonomics — a VESA mount with interface size of 300 x 200 mm is provided for wall-mounting. Swivel, Tilt or Pivot features are not supported on this unit.

Hardware and Audio

The LG OLED48A2PUA comes with a 4-Core CPU. However, LG didn't provide any specification on the RAM on the TV's specsheet.

Speaking of OS, the LG OLED48A2PUA runs webOS 22 Operating System.

For display connectivity, there are three HDMI 2.0 ports and one S/PDIF port on this TV.

For connecting USB devices, you will have two USB 2.0 ports. Other connectivity ports include — 1x Cable/Antenna In (F-type female), 1x RS232 (C) and 1x Ethernet RJ45.

Wireless connectivity options on this TV include Wi-Fi (5Ghz + 2.5Ghz), Wifi-Direct, Bluetooth 5.0 and DLNA.

Now, for audio, it is packaged with 2 x 10W built-in speakers.

As for power usage, on average, it consumes around 50.21 Watts. On standby, it uses 0.5 Watts.

Both 110V and 220V outlets are supported on this unit.
