Just ahead of CES 2026, LG Display has announced the world’s first 27-inch 240Hz 4K OLED monitor featuring an RGB stripe structure. So what the heck is RGB stripe , and why is this announcement important? Simply put, this monitor aims to enhance text readability on OLED gaming monitors.
In some OLED panels, you might notice something equivalent to chromatic aberration around text on web pages, as our friends at PC Gamer note. This phenomenon is known as “text fringing,” and it’s most noticeable on 1440p monitors or panels with lower pixel densities. This happens because the subpixels are arranged in a triangular pattern, which doesn’t always align with how text is rendered. LG Display is getting around that by utilizing the RGB stripe structure.
“The RGB stripe structure arranges the three primary color subpixels — red, green, and blue — in a straight line, significantly reducing visual distortions such as color bleeding and fringing, even at close viewing distances,” says LG Display's press release.
The RGB stripe method isn’t new, but OLED panels that utilize this technique have been limited to 60Hz. LG Displey says its new panel is the first in the world to hit 240Hz.
The RGB stripe method isn’t new, but OLED panels that utilize this technique currently top out at 60Hz, which isn’t ideal for modern gamers who desire higher refresh rates. LG Display says its new panel is the first in the world to hit 240Hz while maintaining an RGB stripe structure.
In addition, the display is capable of switching from high-resolution (4K at 240Hz) and high-refresh-rate (1080p at 480Hz) modes, as we’ve seen in monitors like the LG UltraGear 32GS95UE-B.
LG Display applied new technologies, like increasing the aperture ratio to simultaneously achieve an RGB stripe structure and a high refresh rate. The panel also has a high pixel density of 160 pixels per inch (ppi) to provide sharper detail.
LG Display plans to show off this technology at CES, so you can bet I’ll be there to check it out for myself. Not only am I curious to see how much sharper text appears on this panel, but how this technology affects an OLED monitor’s performance in any meaningful way. Stay tuned for more!
