The benefits of an OLED display

If you’ve never seen an OLED monitor before, prepare to be amazed. Even non-display enthusiasts can immediately see the difference, thanks to OLED’s perfect black levels, stunning color, and details that pop right off the screen.

Why are OLED displays so different? Ultimately, it’s because they’re built completely differently than the LED/LCD panels of the past. LED/LCD panels shine a large backlight through a layer of liquid crystal pixels that change color to create the image on screen. But on an OLED panel, there is no large backlight behind the pixels — each pixel is a tiny organic LED that creates its own light. Since each pixel is an independent light source, each pixel can turn itself completely off, giving you those perfect black levels with no blooming or haloing around bright spots.

This perfect, "infinite" contrast creates an image that truly pops off the screen, even in standard dynamic range (SDR) content. But turn on an HDR game or move, and bright highlights will shine like nothing you've ever experienced. Seriously, if you've never gamed on an OLED display, you have to see it to believe it.

However, there are multiple ways to construct an OLED panel, and different panel manufacturers — like LG Display or Samsung Display — may use different techniques. For example, the red, blue, green, and (sometimes) white subpixels within each pixel can be arranged differently, which can affect how the edges of objects look on screen. Different layers in the panel stack can be arranged in varying ways, which can affect brightness and efficiency. And those two variables — subpixel layout and panel stack — can be combined in different ways, creating the matrix of combinations you'll see in the table above.

And of course, on top of all that, there’s everything that ASUS and ROG add to the mix. Even if two monitors from two manufacturers have the same panel, they may not offer the same experience. We take those panels and add our own hardware and software enhancements to the build of the monitor itself when building the final product, which can make the experience even better than competing models.

So strap in: here's everything you need to know about the OLED panels on the market today.

WOLED: The original OLED gaming monitor panel

Early generations of OLED panels from LG Display used a white organic layer that passed light through a subpixel made of up red, green, blue, and white color filters. While LED/LCD panels use subpixels consisting only of red, green, and blue, the addition of the white subpixel on OLED panels helped boost brightness higher, without excess power consumption.

That power consumption is important, because high heat can cause the organic LEDs to degrade over time, causing the panel to get dimmer or even "burn-in," where the ghost of an image will appear on your display over time. (Think static elements like the Windows taskbar or TV channel logos in the corner of your display.) That's why ROG has always used custom heatsinks and a suite of software technologies called OLED Care to mitigate the risk of burn-in.

WOLED panels have been around for some time, and in large part have been supplanted by newer, superior technology — though you'll still find them on more value-oriented OLED displays like the ROG Swift OLED PG32UCDP and ROG Strix OLED XG32UCWMG. Their bright highlights and perfect black levels will still produce a beautiful image, so if you're on a stricter budget, a WOLED panel will be a mind-blowing upgrade over your old LCD. Later WOLED models from ROG may feature other enhancements, like a TrueBlack Glossy coating that keeps black levels deep in well-lit rooms by suppressing glare.

QD-OLED: How quantum dots change the picture

Samsung Display has invested heavily in a slightly different type of OLED panel known as QD-OLED, where the "QD" stands for Quantum Dot. Quantum Dots are tiny semiconductor crystals that emit colored light. QD-OLEDs use a blue light emitting layer, with a Quantum Dot layer made up of red, green, and blue subpixels to create a wide range of colors.

The main advantage of Quantum Dot OLED is color volume, allowing you to see brighter, more vivid colors that aren't in danger of being washed out by the additional white subpixel. While that white subpixel allowed early WOLED panels to get brighter overall, QD-OLED had the edge in color reproduction, especially when it comes to HDR content.

This panel structure does have some other differences, however. Instead of a red, green, and blue subpixel striped next to each other, early QD-OLEDs use a triangular subpixel layout, which caused some "fringing" artifacts around text or other objects.

In addition, earlier QD OLED panels tend to have a slight purplish tint to the display in brighter environments. That's due to high levels of ambient light interacting with the quantum dot layer. This made QD-OLED ideal when gaming in a dark room, while WOLED was preferred by those reading lots of text or gaming in a brighter room.

Many of these drawbacks would later be improved upon, but QD-OLEDs like the ROG Swift OLED PG27AQDPR and ROG Strix OLED XG27AQDMES are still popular choice for many gamers due to that stunning color.

Tandem OLED : Brighter panels with longer lifespans

In 2025, the first Tandem gaming OLED monitors hit the scene. Tandem OLED panels use multiple light-emitting layers that work together in tandem to produce higher brightness with less power consumption. That means punchier highlights in HDR, while protecting against burn-in and prolonging the panel's lifespan. In other words, it was a true upgrade all around.

More importantly, this technology could be used with both LG Display's WOLED panels and Samsung Display's QD-OLED panels.

Tandem WOLED

LG Display's first Tandem OLED panels use the same subpixel structure as the WOLED panels that preceded them, which means each pixel has one white subpixel alongside a red, blue, and a green subpixel. And just like the previous generation, the extra white subpixel helps make images bright and punchy. They also featured boosted color volume thanks to the tandem structure, narrowing the gap with the previous gen QD-OLED panels.

Tandem OLED monitors from ROG — like the ROG Swift OLED PG27AQWP-W and ROG Strix OLED XG27AQWMG — are also more likely to feature the TrueBlack Glossy coating, which provides that extra-deep black level with less glare.

Tandem QD-OLED

Samsung Display's QD-OLED lineup also featured Tandem OLED improvements that it called Penta Tandem, drastically increasing the brightness from previous QD-OLEDs while keeping the stellar color performance of Quantum Dots — not to mention the increased lifespan and burn-in mitigations that come with a tandem panel structure. You'll find this panel in ROG monitors like the ROG Swift OLED PG32UCDM Gen3 and ROG Strix OLED XG27UQDMS, with the PG32 also featuring a new BlackShield film that improved the panel's scratch resistance while also mitigating that purplish tint, providing better black levels in well-lit rooms.

RGB Stripe OLED: Improving OLED text clarity

The latest in panel technology, RGB Stripe Pixel OLEDs change the game in a few ways. RGB Stripe refers to the subpixel layout of these displays, which feature a red, blue, and green subpixel in a side-by-side "striped" arrangement, which drastically reduces text fringing and improves color reproduction. Both Tandem OLED and QD-OLED displays can be manufactured with RGB Stripe layouts.

Tandem RGB WOLED

LG Display features RGB stripe subpixels on many of their latest Tandem WOLED panels. Certain panels may eschew the white subpixel in this iteration, and those are the panels ROG uses in its latest monitors like the ROG Swift OLED PG32UCWM and ROG Swift OLED PG27UCWM. Removing the white subpixel helps improve fringing artifacts around text and other UI elements, while also featuring more vibrant colors that aren't washed out by the white subpixel. (Note that the “W” refers the white backlight, not a white subpixel, so these are still referred to as Tandem RGB WOLED — though sometimes you’ll also see them called Tandem RGB OLED, or by LG as Primary RGB Tandem 2.0.)

Tandem RGB QD-OLED

Samsung Display also uses RGB stripe pixel tech on its latest QD-OLED panels, which is a big improvement from its previous triangular subpixel pattern. The new vertical layout — which Samsung calls V-Stripe — reduces the text fringing and other artifacts caused by the old triangular layout, while keeping the excellent color performance of Quantum Dots. The ultrawide ROG Swift OLED PG34WCDN and ROG Strix OLED XG34WCDMS feature this new panel tech, both with the addition of the aforementioned BlackShield film for deeper black levels and improved scratch resistance.

Which OLED panel is right for you?

If that feels overwhelming, don't worry too much — it actually gets simpler once you break down the field by price bracket. Since older WOLED and QD-OLED panels are cheaper to manufacture, you'll find them in more value-oriented models, like those in our ROG Strix line. Pick WOLED if you want higher brightness and/or play in a well-lit room, and QD-OLED if you value punchier colors and game in a dark room. Color-critical creative work will also benefit from QD-OLED's color performance.

If you have the extra budget and want the best of the best — with better black levels, less text fringing, improved color performance, and lower burn-in risk, go for one of the newer Tandem RGB options. The gap between Tandem RGB WOLED and Tandem RGB QD-OLED has closed significantly with all the latest panel improvements, but the same guidelines apply — Tandem RGB WOLED has the purest blacks in well-lit rooms, while Tandem RGB QD-OLED has slightly better color performance and excels most in a dark room.

FAQ

What's the difference between QD-OLED and Tandem OLED?

QD-OLED refers to the quantum dot color filters that Samsung uses on its OLED panels. Tandem OLED refers to the way the layers of the OLED panels are structured. You can actually get both technologies in the same display, too — not all Tandem OLEDs use quantum dots, but Tandem QD-OLED and Tandem RGB QD-OLED monitors do, so just look for both terms when shopping for a display if you want the best of both worlds.

Is Tandem OLED better than QD-OLED for gaming?

The latest Tandem OLED monitors are better for gaming, since they allow for higher brightness with lower power consumption. However, Tandem OLED is not mutually exclusive with QD-OLED — newer QD-OLED panels can also use a Tandem structure to get the same benefits. If you want the stunning color performance of QD-OLED, look for a newer Tandem RGB QD-OLED model for the best picture.

Why does text look fuzzy on some OLEDs? Does RGB Stripe fix this?

Color "fringing" on text and other objects is a result of the subpixel layout on some OLED monitors — the way the red, blue, and green subpixels were arranged. Older models of QD-OLED used a triangular subpixel layout that caused this artifact to appear, and WOLED displays with a white subpixel also displayed some of this as well. RGB Stripe drastically reduces the appearance of this fringing, so you get a sharper, clearer image.

Does Tandem OLED solve burn-in?

Tandem OLED doesn't prevent burn-in completely, but it does reduce the risk of burn-in at higher brightness levels, which was a challenge with early generation OLEDs. Combine Tandem OLED with large custom heatsinks like those on ROG monitors — plus a three-year warranty for peace of mind — and you can rest assured your OLED will look great for years to come.

Which ASUS ROG monitors use QD-OLED vs. Tandem OLED?

ROG provides monitors with all types of panels, so users can choose the one that works best for them. Our latest Tandem RGB QD-OLED monitors include the ROG Swift OLED PG34WCDN and ROG Strix OLED XG34WCDMS, while the latest Tandem RGB WOLED monitors include the ROG Swift OLED PG32UCWM and ROG Swift OLED PG27UCWM. For more information, check out our full monitor lineup and look for your preferred panel type in the description.

Is V-Stripe the same as RGB Stripe Pixel OLED?

Yes, V-Stripe is Samsung's name for the RGB Stripe technology in their QD-OLED Panels. This name is not used by LG for their RGB Stripe panels, but for all intents and purposes, you can consider these two names for the same type of subpixel layout.

QD-OLED vs WOLED vs Tandem OLED — which should I buy?

In short, grab a Tandem RGB WOLED if you're playing in a well-list room and want perfect blacks with a bit of extra brightness. If you're playing in a dark room, Tandem RGB QD-OLED will give you a boost of color — the blacks aren't as perfect if you have a lot of ambient light, but in a dark or dim room, they'll look excellent. Gamers on a budget can look at slightly older or more value-oriented models featuring non-RGB WOLED or QD-OLED panels, which will still provide great image quality at a more affordable price.
