Understanding QD-OLED and W-OLED
QD-OLED (Samsung Display)
QD-OLED uses a blue OLED emitter layer combined with quantum dot color converters. Blue light from the OLED passes through red and green quantum dot films to produce those colors, while unfiltered blue light creates the blue subpixel. This approach eliminates the need for traditional color filters, resulting in higher color purity and brightness efficiency.
Key Characteristics:
- *Triangular subpixel layout (RGB)
- *No color filter layer -- higher light efficiency
- *Quantum dots for color conversion
- *Manufactured by Samsung Display
- *Used in Samsung, Alienware, and MSI monitors
W-OLED (LG Display)
W-OLED (White OLED, also called WOLED or WRGB OLED) uses white OLED emitters behind color filters. Each pixel has four subpixels: red, green, blue, and white. The white OLED emits all wavelengths of light, and color filters separate out the desired color. The additional white subpixel boosts overall brightness.
Key Characteristics:
- *WRGB subpixel layout (4 subpixels per pixel)
- *Color filter layer for color accuracy
- *White subpixel boosts SDR brightness
- *Manufactured by LG Display
- *Used in LG, ASUS, and Corsair monitors

Color Performance: The Biggest Differentiator
Color is where QD-OLED and W-OLED differ the most. Samsung's quantum dot approach produces purer, more saturated colors with a wider color volume, while LG's color-filter method is slightly more constrained but still excellent by any standard.
QD-OLED Color Advantages
- +Wider DCI-P3 coverage: 99-100% vs 96-98% for W-OLED. You get more vivid reds, greens, and blues.
- +Superior color volume: Colors stay saturated at higher brightness levels. Bright scenes look vibrant rather than washed out.
- +No color filter losses: Since quantum dots convert light directly, there is less light wasted compared to traditional color filters.
- +Better for HDR gaming: The combination of wide gamut and high brightness makes HDR highlights pop with intense, saturated color.
W-OLED Color Strengths
- +Excellent accuracy out of the box: W-OLED panels tend to have lower Delta E values (color error) in factory calibration.
- +Proven color science: LG has refined WRGB technology over a decade in TV production. The calibration is mature and reliable.
- +Consistent uniformity: The white subpixel helps maintain even color temperature across the entire panel.
- +96-98% DCI-P3 is still outstanding: The difference is only visible in direct side-by-side comparisons with QD-OLED.
Brightness and HDR Performance
Both OLED technologies deliver true HDR with infinite contrast and per-pixel dimming. The difference lies in peak brightness and how well colors are maintained at high luminance levels.
| Brightness Metric | QD-OLED | W-OLED |
|---|---|---|
| SDR Full Screen | 250-300 nits | 200-280 nits |
| HDR 10% Window | 1000-1300 nits | 800-1000 nits |
| HDR 3% Window | 1300-1500 nits | 1000-1200 nits |
| ABL Aggressiveness | Moderate | Moderate-High |
What This Means in Practice
QD-OLED's brightness advantage is most noticeable in HDR content with small bright highlights -- think sunlight reflections, explosions, or neon signs against dark backgrounds. For SDR desktop use, both technologies are similar and adequate for typical office lighting. Neither OLED type is bright enough to compete with high-end Mini-LED monitors in direct sunlight.
Coatings and Text Clarity
Anti-Reflective Coatings
Samsung QD-OLED panels feature one of the best anti-reflective coatings in the monitor industry. It significantly reduces reflections while maintaining deep blacks -- a rare combination. LG W-OLED panels use a semi-glossy coating that handles reflections adequately but not as effectively as QD-OLED in bright rooms.
Matte-like anti-reflective finish. Excellent in well-lit rooms. Minimal sparkle effect. Preserves deep blacks better than most matte coatings.
Semi-glossy finish. Good black depth but more visible reflections in bright environments. Works well in controlled lighting setups.
Text Clarity and Subpixel Layout
Text rendering is one area where W-OLED has a clear advantage due to its WRGB subpixel layout, which more closely resembles the RGB stripe layout that font renderers are optimized for.
Triangular RGB layout caused color fringing on text in early models. 2025-2026 panels are significantly improved but may still show slight fringing at small font sizes. ClearType adjustments help.
WRGB layout produces cleaner text rendering. Small fonts are sharper and easier to read for extended periods. Better suited for productivity-heavy users who also want OLED quality.

Frequently Asked Questions
For most gaming scenarios, QD-OLED has a slight edge due to its wider color gamut and higher peak brightness in HDR content. The Samsung QD-OLED panels deliver more vivid and saturated colors, which makes HDR games look especially impressive. However, W-OLED panels from LG offer excellent uniformity and very competitive response times. Both technologies deliver a vastly superior gaming experience compared to LCD panels.
Early QD-OLED panels (2022-2023) had noticeable color fringing on text due to their triangular RGB subpixel layout. Samsung has significantly improved this in 2024-2026 panels with refined subpixel structures and better anti-aliasing. Current QD-OLED monitors have acceptable text clarity for most users, though W-OLED panels with their WRGB subpixel arrangement still produce slightly cleaner text at small font sizes.
Both technologies have similar burn-in risk profiles. LG W-OLED panels benefit from the added white subpixel which can reduce strain on individual color elements. Samsung QD-OLED panels use quantum dots which are inherently stable but rely on blue OLED emitters that degrade slightly faster. In practice, both manufacturers include effective burn-in prevention features like pixel shifting, logo luminance detection, and panel refresh cycles. With normal mixed-use behavior, burn-in is unlikely to be an issue within the first 3-5 years for either technology.
It depends on your priorities. QD-OLED is worth the premium if you value the widest possible color gamut, higher HDR peak brightness, and the most vivid image quality for gaming and media consumption. W-OLED is the better value if you prioritize text clarity for mixed productivity and gaming use, or if you want a proven technology with wider availability and lower prices. For pure gaming, QD-OLED has a slight edge. For general use, W-OLED is more practical.
