How to fix remote issues with LG A1, B1, C1 and G1

by

When using your LG A1, B1, C1 or G1, you may notice that the included Magic Remote is not connecting, registering or working correctly.

You can check out this troubleshooting guide at Seeking Tech to see how to fix the remote controller issues with these OLEDs.

1. The first step you can take is to replace the batteries in the remote control. For the uninformed, the Magic Remote support 1.5 V AA type.

If you don’t have that type available, then you can purchase the Amazon Basics AA 1.5 Volt Performance Alkaline Batteries with this link (#CommissionsEarned) on Amazon.

Make sure you replace both batteries as mixing old and new together may end up causing them to leak or overheat.

2. You should also make sure that your remote controller has a direct line of sight to your A1, B1, C1 or G1 television set.

3. Furthermore, you should ensure that you don’t have a sticker, tape and any other objects blocking the receiver on your TV.

4. If you have a Wi-Fi access point device located near the television set, then the Magic Remote may not work properly due to the wireless frequency interference.

Therefore, you should move the access point to at least 0.65 feet (or 0.2 meter) away from your A1, B1, C1 or G1.

5. If you haven’t done so already, make sure you register your remote to your TV.

In order to do so, you need to do the following:

  • First off, make sure that the batteries for the remote controller are properly installed.
  • Next, you need to press the power button on your LG TV to power it on.
  • With your TV turned on, point the remote directly to the screen.
  • Finally, press down on the wheel (which is the OK button) on the remote to register it to your A1, B1, C1 or G1.
  • If your remote is still not registering, then you can power cycle your television by pressing the power button on the TV to turn it off and then press the same button again to turn it back on. Afterwards, you can try pressing down of the wheel on the remote again.

6. If the LG Magic Remote is still not working properly, then you can try unregistering and then re-registering it to your television.

In order to do so, you need to take the following steps:

  • Make sure that the batteries are properly installed inside the remote controller.
  • Press the power button on your A1, B1, C1 or G1 to turn the television it on.
  • Point the Magic Remote directly at your TV.
  • With the remote pointed directly at the television, press and hold both the back button and the home button at the same time for five seconds. This will deregister the remote from the TV.

How to prevent screen burn ins with LG A1, B1, C1 and G1

In order to prevent permanent screen burn ins or temporary image retentions, you can do the following:

1. One of the ways to prevent screen burn in on the A1, B1, C1 and G1 is to avoid displaying video outside of the 16:9 aspect ratio.

The 4:3 and 21:9 aspect ratios may display black bars that stay on the screen.

2. You should also make sure that there is no fixed image that appear on the screen.

These potential problematic images include a channel number, logo and menu.

3. If you decided to use your LG A1, B1, C1 or G1 even with a persistent image that appears on screen, then you can either turn off your TV once or make the screen display something else once in a while.

4. Most modern PC, game consoles and other input devices should have features where you can use dim the screen, use a screen saver and/or go into sleep mode. So, make sure you activate these features on any devices you have connected to the video inputs of your LG television set.

Keep in mind that, if the device connected to your LG TV goes to sleep, then the TV will be turned off after 15 minutes if it doesn’t detect a video signal.

To do so, you need to do the following:

  • On the Magic Remote that came with your LG television, press the gear-looking button to open the Quick Settings menu.
  • Next, you need to select All Settings.
  • Afterwards, select OLED Screen Saver (if you have a newer firmware, then this was renamed to OLED Panel Care).
  • In the OLED Screen Saver or OLED Panel Care menu, make sure to enable Screen Move and set Adjust Logo Brightness to Low.

What is Pixel Cleaning on A1, B1, C1 and G1?

Pixel cleaning is a feature that will even out the individual pixels of your A1, B1, C1 and G1 television set. This process is done by aging the less worn-out pixels to match the more worn-out ones.

Although you should get a more consistent picture across the screen, the lifespan of your TV set will also be reduced. Therefore, we don’t recommend using this feature manually.

Keep in mind that lite version of pixel cleaning will run automatically on the LG A1, B1, C1 and G1 after four hours of cumulative usage per day. A full pixel cleaning will also automatically occur after 2,000 hours of cumulative usage per year.

If you want to still want to manually use the pixel cleaning feature, then you can take the following steps:

  • Press the quick settings button on your TV remote.
  • Select All Settings.
  • Select Support.
  • Select OLED Screen Saver or OLED Panel Care.
  • Select Pixel Cleaning,
  • Select Start Now.

How to fix burn-in and image retention on A1, B1, C1 and G1

If you see an image artifact on the screen of your A1, B1, C1 or G1, then it could either be a permanent burn-in or temporary image retention.

The only way to find out for sure is to make your TV display something else that don’t have a fixed image. If the aforementioned image artifact is a temporary image retention, then it should eventually go away.

If the image doesn’t go away, then you are stuck with a permanent burn-in, which unfortunately can’t be fixed.

What’s the difference between the LG A1, B1, C1 and G1 for gaming?

by

In 2021, LG released four 4K OLEDs. So, which of the A1, B1, C1 or G1 TVs are the best when it comes to playing games on the PC, PlayStation 5, Xbox Series X, Xbox Series S and other gaming systems?

You can find out in this comparison guide between these four TVs.

Quick Summary

The LG C1 and LG G1 are two of the best OLED gaming television released by LG in 2021. Both of these TVs come with four HDMI 2.1 ports in addition to support for 120 frames per second, Dolby Vision, HDR10, FreeSync, GYSNC and Variable Refresh Rate.

The C1 and G1 are pretty even when it comes to both HDR brightness output and input lag reduction. Since the C1 is more affordable than the G1, then we recommend getting the C1 out of these 2021 LG OLEDs if you want the best gaming TV.

The LG B1 is a level below the C1 and G1 in terms of HDR brightness output and input lag reduction. It also only comes with two HDMI 2.1 ports. With that said, the B1 does come with support for 120 fps, Dolby Vision, HDR10, FreeSync, GYSNC and Variable Refresh Rate.

The LG A1 is not suitable for the PlayStation 5, Xbox Series X or Xbox Series S as it lacks support for HDMI 2.1, 120 fps, FreeSync, GYSNC and Variable Refresh Rate. The A1 also has underwhelming HDR output.

The A1, B1, C1 and G1 all come with an antenna/cable input, which can be used to connect the NES, Super NES, Sega Master System, Sega Genesis and other retro consoles from the 8-bit and 16-bit era.

None of these OLEDs include any composite or component inputs. Therefore, a HDMI adapter is needed if you want to connect consoles such as the PS1, PS2, N64, GameCube, Sega Saturn, Dreamcast, Xbox and other similar systems.

HDR Features

The LG A1, B1, C1 and G1 support the following HDR features:

  • Dolby Vision
  • HDR10
  • HLG
  • Wide Color Gamut

For the uninformed, the new Xbox Series S and Xbox Series X support the Dolby Vision and HDR10 formats.

The other HDR consoles (PS4, PS4 Pro, PS5, Xbox One S and Xbox One X) support the HDR10 format.

HDR Brightness in Game Mode

When it comes to HDR brightness, the LG C1 edges the LG G1 at real scene highlight, according to testing done by RTINGS.com. With that said the G1 does outperform the C1 in most other scenarios that were tested.

Overall, we consider that both the CL are and G1 are about even when it comes to HDR brightness output as both are decent HDR TVs. The B1 has passable HDR brightness while the A1’s HDR brightness output is underwhelming.

If you are looking for a simple wall mount for your A1 without any extra frills, then we recommend checking out the MD2163-K Fixed TV Mount from Mounting Dream.

When paired with the 2021 LG OLED, the mount will give you a low profile look as the screen will be sitting at just 1.2” away from the wall.

The MD2163-K has a VESA mounting range of 200 mm x 100 mm to 600 mm x 400 mm, which includes the 300 mm x 200 mm pattern. Its heavy-duty steel frame can also hold up to 132 pounds. Therefore, it should be compatible with the 55-inch and 65-inch versions of the LG A1 4K Smart OLED TV.

You can install the MD2163-K, which comes with a bubble level tool, on concrete in addition to studs with distances that are 16”, 18” or 24” apart.

Compatible tilting wall mount

You may also want to consider getting a mount with a tilting feature as it provides better viewing and prevents screen glares if you decide to put your LG A1 on the higher side of a wall.

If you are interested in getting one, then we recommend taking a look at the PILTK4 Tilt TV Wall Mount Bracket from Pipishell. With this product, your OLED television will be sitting at 1.5” away from the wall.

By using its dual hooks with anti-drop design, you will be able to tilt the television set a maximum of 7 degrees downwards.

The PILTK4 supports the 300 mm x 200 mm VESA pattern as it has a range of 100 mm x 100 mm to 600 mm x 400 mm. As it can also hold up to 132 pounds, this mount should support both screen sizes of the A1 4K Smart OLED.

When it comes to installation, you can put the Pipishell on brick, concrete, studs that are 16” apart or studs that are 24” apart. The product includes a bubble level and three cable ties.

Compatible full motion wall mount

If you would like to watch your A1 from multiple angles, then you should consider getting a mount that is capable of swiveling. If you are interested in one, then we recommend checking out the EGLF3 Swivel Articulating TV Wall Mount Bracket from ECHOGEAR.

With this product, your LG TV will sit at 2.9” away from the wall. You can then extend it for up to 19 inches.

The extension gives you the ability to swivel the A1 at up to 140 degrees, which is 70 degrees to the left or 70 degrees to the right. You can also tilt your screen at a maximum of 15 degrees.

The EGLF3 has a VESA range of 200 mm x 100 mm to 600 mm x 400 mm, which includes the 300 mm x 200 mm pattern. With a weight capacity limit of 110 pounds, the mount should support both the 55” and 65” screen sizes of the LG A1.

When it comes to installation, you can put the ECHOGEAR EGLF3 on a concrete wall, studs that are 16” apart or studs that are 17” apart. After installation, you can re-level at up to 3 degrees and re-center at up to 5.4 inches.
