RGB vs BGR Subpixel Layout – What Is The Difference?

Displays using BGR, triangular RGB, and RWBG stripe subpixel layouts have blurry text in comparison to the standard RGB layout. Here's why.

If you’re buying a new monitor for productivity work or anything else that involves a lot of reading and typing, it’s important that you pick a display with an RGB (Red, Green, Blue) subpixel layout for the sharpest and clearest text!

As manufacturers don’t specify the type of subpixel layout used by the display, you will have to rely on monitor reviews for this information.

Luckily, it’s mostly the 43″ 4K monitors and very old models that use the BGR (Blue, Green, Red) subpixel layout that’s responsible for making text appear blurry, mainly in Windows.

Here’s what you need to know about different display subpixel layouts, and what you can do to improve text clarity if you have a BGR-layout monitor.

BGR vs. RGB Subpixel Layout

BGR-layout monitors have an inverse subpixel arrangement in comparison to the standard RGB pixel structure.

This causes text to appear blurry on BGR monitors (particularly those with low pixel density) as Windows handles subpixel anti-aliasing according to the more common RGB layout by default.

As a result, you get something like this:

This is mostly noticeable with small text, and it’s not an issue for video games, movies and other multimedia use.

How To Improve Text Clarity On BGR-Layout Monitors

In Windows, there are several ways to improve text clarity if you have a monitor with a BGR subpixel layout.

Method 1: Scaling

If you have a monitor with relatively low pixel density, such as the popular 43″ 4K monitors with ~103 PPI (pixels per inch), you can simply apply scaling, which will make text larger and sharper.

You will have to sacrifice screen real estate in the process though, as text and other items will take up more screen space.

Method 2: Adjust ClearType

In Windows, you can type in ‘Adjust ClearType text’ in your search bar, which will open an application that can make text appear sharper and clearer via anti-aliasing.

You will be given several text samples, and you just have to choose which one looks the best to you. After five examples, Windows will automatically apply ClearType and make text look a bit better.

In the first example, you should select the sample on the right if you have a BGR monitor for the best results.

This will make text appear sharper in some Windows applications, but sadly not all of your applications will respect your ClearType settings; this includes web browsers, video games, etc.

Method 3: Flip The Screen

The last method you can try is a bit less convenient as it includes mounting the monitor upside-down and flipping the picture by 180° in your display settings.

This way, you essentially get the RGB subpixel layout, but besides the aesthetic issue here, you’ll also have to consider cable management, OSD hotkeys/joystick access, and buying a mounting arm that can reliably hold the screen.

Additionally, with the flipped image, you won’t be able to use variable refresh rate and input lag would be a bit higher. This may not be an issue for everyday use, but it definitely is for gaming.

Other Subpixel Layouts

RWBG

RWBG vs RGB OLED

LG Display’s OLED displays have an RWBG subpixel layout. They’re aligned in a regular BGR line, but with the added white subpixel for increased brightness and efficiency.

This affects the clarity of tiny text as it adds minor fringing. Here’s an example from our ASUS PG27AQDM review.

In 2024, LG will release new OLED panels with an RGWB subpixel layout, which should improve text and fine detail clarity. For 2025, they’re considering developing true RGB panels.

Note that some LG’s OLED monitors, such as the LG 32EP950, use an OLED panel by JOLED, which actually has a true RGB subpixel layout.

QD-OLED

QD OLED Subpixel Layout

Samsung QD-OLED panels have regular RGB subpixels but in a triangular layout, which can also cause noticeable fringing on things such as small text.

However, it’s not noticeable in games and videos, and most people won’t notice it in regular use unless looking at the screen from up close. Some users sensitive to this type of visual artifact might find it bothersome though.

We find that text fringing is less noticeable on QD-OLED panels than it is on LG’s W-OLED panels. The second-gen QD-OLED panels will also have a slightly different subpixel shape for even better text clarity.

Whichever subpixel layout your display uses, we recommend trying out BetterClearTypeTuner with more configuration for text clarity. Hopefully, we’ll get proper OS-level support for subpixel text rendering at some point.
