What an OLED gaming monitor is

Those inky blacks you’ve seen in OLED demos are real. An OLED gaming monitor is a panel where each pixel makes its own light. A black pixel is off. Samsung’s OLED monitors page says the same thing: self-lit pixels, and each pixel turns off completely for true blacks. There is no backlight behind a sheet of crystals, which is why a listing that says OLED sits outside IPS and VA. For full picks, see the best gaming monitors. The panel type is the picture after those three numbers match.

I play on a 1080p 240 Hz and a 1440p 155 Hz monitor, driven by an RTX 5080 and an AMD Ryzen 9 9950X3D2. Below is what a listing should name, and what the warranty card actually covers. More monitor guides.

The screen is for games in a dim room.

Mini-LED promises OLED-like contrast for less. The catch is halos. Pick resolution, size, and refresh first.

The short version: OLED turns the pixel off. Buy the resolution and Hertz the PC already holds. Read the burn-in sentence on that SKU’s warranty.

What the pixel is doing

On an LCD, a backlight stays on and liquid crystals block more or less of it. A dark scene is as dark as that blocking gets. IPS versus VA is how those crystals behave. Mini-LED is still that design, with the backlight split into zones. Zones are larger than pixels, so a small bright object on black can light every pixel that shares the zone. OLED does not dim a zone. It turns the pixel off. In a dark room that is the whole of the difference you can see.

The highlight is a separate number. HDR on the box means the panel accepts a signal. It does not say how bright a small patch gets, or how bright the whole window stays when most of the screen is white. ASUS names an optional uniform brightness setting on the PG27AQDP so luminance stays consistent when you resize a window. That is the maker admitting the full window and the small patch are not the same job. Shop the typical-brightness row and the HDR badge on the listing in front of you. Monitor HDR is that brightness page.

A printed millisecond is still one lab transition. Boxes like 0.03 ms because the pixel’s own light rises and falls instead of waiting on crystals. All three named panels print that figure. Watch the edge you already know, a dark object moving on a dark background. The fraction on the box is not the refresh rate, and it is not how long a click takes to reach the screen. Input lag is that other wait.

Two families the makers actually name

The gaming OLEDs in shops are one of two panels. The listing has to say which.

Samsung’s OLED FAQ draws the split this way. OLED uses self-lit pixels. QD-OLED combines that emissive layer with quantum-dot technology, which Samsung says results in brighter highlights, higher color accuracy, and a wider color range. The G60SD page leads with QD-OLED picture quality and a matte Glare Free finish. Samsung’s CES 2024 note on this family also names OLED Glare-Free as the coating that minimizes reflections.

ASUS names WOLED on the PG27AQDP. The same ROG page describes WOLED as a white light source with traditional color filters (RGBW subpixels), and says that stack is the one they point at for peak white brightness and deep-black uniformity in a bright room. The spec sheet prints Panel Type: WOLED, Display Surface: Anti-Glare, 99% DCI-P3, VESA DisplayHDR 400 True Black.

LG’s 27GS95QE-B page says OLED. It does not print WOLED on the US product title. Regional sheets add Anti-Glare / Low Reflection and 275 cd/m² typical. A listing that only says OLED has not named the family.

A bright room changes what a black looks like next to a window. Samsung sells Glare Free on the G60SD for that reason. ASUS sells Anti-Glare on the PG27AQDP and talks about WOLED in well-lit rooms. LG prints Low Reflection. The finish is a row on the page, not a winner I picked. ASUS also prints a Clear Pixel Edge Algorithm next to crystal-clear text. That is the maker naming a text-edge feature, not a score. 4K is the density page. 27-inch 1440p is the size class on the 1440p 240 Hz page.

Burn-in is the sentence on the warranty card

Burn-in, in the maker pages, is a static shape that stays in one place until the pixels that drew it no longer match their neighbors. A taskbar, a chat column, a health bar, a logo. ASUS’s older OLED-care FAQ says image persistence can occur if a static high-contrast image is displayed for a prolonged period. Samsung’s Safeguard+ copy talks about logos and taskbars.

Samsung. The US OLED monitors page: a 3-year warranty includes burn-in coverage, on select models, with a footnote to Samsung’s standard limited-warranty legal page. The G60SD UK spec is blunter: burn-in at normal usage covered within the warranty, but not covered for commercial use, abuse, or misuse. OLED Safeguard+ is Samsung’s name for the defenses: dynamic pixel-shift, a cooling system, logo and taskbar detection, and thermal modulation. The thermal-modulation footnote says the feature is always active when Adjust Logo Brightness is High, and only in preset picture modes when that setting is Off or Low.

ASUS. The OLED warranty FAQ splits the family. Newly launched models from the PG32UCDM onward print 3 years including panel burn-in on the product spec page. A named older list — PQ22UC, MQ13AH, MQ16AH, PA27DCE, PA27DCE-K, PA32DC, PG27AQDM, PG34WCDM, PG42UQ, PG48UQ, PG49WCD — stays at 24 months. Other OLED models not on that list start to apply 36 months. The PG27AQDP is not on the 24-month list. Its spec page prints 3 years (including panel burn-in). OLED Care+ on that page: pixel locations shift periodically, taskbar detection dims the bar, logo brightness drops, a custom heatsink is there to reduce the risk of burn-in. Those features lower a risk. They are not a promise the picture never keeps a hint.

LG. The US OLED monitor limited-warranty card is 2 years parts and labor from the original retail purchase, internal and functional parts only, including the OLED display panel, under normal and proper use. It also excludes misuse, abuse, commercial-style use that is not the intended purpose, and damage from improper setup. So don’t assume burn-in is covered. Read the card in the box.

LG’s UltraGear OLED page does name OLED Screen Move: Settings, General, OLED Screen Move. After a two-minute delay at startup, the image shifts at least 8 pixels once a minute. Mode 2 is the longest move. That is the maintenance feature. It is not the warranty.

A warranty line is not a lifespan. It is the window in which the maker will repair or replace the panel if the failure they named shows up under the use they named. Leave the maker’s pixel-shift, logo dimming, and panel refresh on unless the manual says otherwise. ASUS’s care article says disabling those functions may affect warranty coverage.

The Hertz on the box is still a ceiling you have to set

OLED didn’t create a new refresh rule. The panel can start a new picture as often as the listing pairs with the resolution and the port. LG’s 27GS95QE-B is 240 Hz at 1440p on DisplayPort 1.4 or HDMI 2.1. Samsung’s G60SD is 360 Hz at 1440p on DisplayPort 1.4 and HDMI 2.1. ASUS’s PG27AQDP is 480 Hz at 1440p on DisplayPort 1.4 with DSC and HDMI 2.1. Those are three different ceilings.

How to set 144 Hz is the same Windows page for 240, 360, or 480. Select Start, then Settings, System, Display, Advanced display. Pick the rate you paid for on the screen you are looking at. Microsoft’s asterisk next to a Hertz means that rate does not support the current resolution. Selecting it changes the resolution.

A rate that exists only at 1080p, or only on one socket, is not the rate of the desktop you play on. Use the cable that came with the monitor, or one rated for that port version. Then set variable refresh if both the card and the listing speak it. All three named panels list a VRR badge: G-SYNC Compatible and FreeSync Premium Pro on the LG, FreeSync Premium and G-SYNC Compatible on the ASUS, FreeSync Premium Pro on the Samsung. VRR follows the frames you have. It does not create 360.

Most games are drawn for 16:9. All three of these SKUs are 16:9. Width is a desk decision. Ultrawide is the other shape.

What to read on the listing

Read the resolution, the inches, and the refresh at that resolution. Then read OLED, and which family, QD-OLED or WOLED, if the page names one. Read a typical-brightness number and an HDR badge. Read whether burn-in is in the warranty for that SKU, and whether the menu has a pixel shift and a panel refresh. The 0.03 ms line is the lab transition.

Do not shop an old ceiling. ASUS already sells 480 Hz at 1440p OLED. Samsung already sells 360 Hz. LG already sells 240 Hz.

I would not buy OLED first if the PC does not already hold the Hertz on the box at that resolution. from Overwatch to WoW, on a 1080p 240 Hz and a 1440p 155 Hz monitor. The Zarya guide is the aim page. A static UI all day is the load the warranty pages keep naming. A moving match is a different load.

How to choose

1. Keep resolution, size, and Hertz first. 27-inch 1440p is the usual competitive OLED size. 360 and 480 only help if the game is already producing those frames.
2. Name the family. QD-OLED or WOLED if the listing says so. OLED alone is incomplete.
3. Read typical nits and the HDR badge. Uniform brightness, if the menu has it, keeps a white window from jumping.
4. Read the warranty sentence for that SKU. Three years including burn-in on the PG27AQDP. Burn-in at normal usage on the G60SD. Two years including the OLED panel on LG’s US card, without the word burn-in on the card I cited.
5. Leave pixel shift, logo dimming, and pixel cleaning on. Then set the rate and the port the listing named.

OLED turns the pixel off. That is the picture. It does not add frames, and it does not cancel a static HUD. Buy it when the three numbers already match and the warranty line is one you can live with. More monitor guides.

Common questions

What is an OLED gaming monitor?

It's a monitor where every pixel makes its own light and can turn off completely, giving you perfect blacks and extremely fast response. You still choose resolution, size and refresh rate first.

What is the difference between QD-OLED and WOLED?

QD-OLED (Samsung) adds quantum dots for brighter, more saturated colors, while WOLED (LG) uses white subpixels with color filters. Both give true blacks, so check which one the listing names.

Do OLED monitors get burn-in?

They can, if bright static images stay in one place for a long time. Many brands now cover burn-in under warranty, so check the warranty for the exact model before buying.

Which OLED monitor brands cover burn-in?

Samsung offers 3 years including burn-in on select models, ASUS covers 3 years including burn-in on most current ROG OLEDs, and LG covers 2 years including the OLED panel. Always confirm for the specific model.

Does 0.03 ms response time matter on an OLED?

Yes, in practice. OLED pixels change almost instantly, so motion looks very clear, but that number isn't your refresh rate or input lag.

Are OLED monitors bright enough for a bright room?

They can be dimmer than LCDs for full-screen white. Monitors like the LG 27GS95QE-B are around 250 to 275 nits typical, so in a sunny room, a bright IPS may be easier to see.

Should I choose resolution and refresh rate before OLED?

Yes. OLED improves contrast and motion, but it doesn't add pixels or frames. For competitive games, 1440p at 27 inches with a refresh rate your PC can hold is the sweet spot for most players. I play Overwatch on 1080p 240 Hz and everything else on 1440p 155 Hz.

Is OLED better than Mini-LED?

For contrast, yes. OLED turns off each pixel for true black, while Mini-LED uses dimming zones that can glow around bright objects. Mini-LED can get brighter, which helps in bright rooms.

Do I need a special cable for a high refresh rate OLED?

Yes, you need DisplayPort 1.4 or HDMI 2.1 for 1440p at 240 Hz or more. An older HDMI cable is a common reason your monitor gets stuck at a lower refresh rate.
