❓
Frequently Asked Questions
01 What type of panel does the Asus ROG Swift OLED PG39WCDM use? ›
It uses an OLED panel, where each pixel generates its own light. This produces perfect blacks and near-infinite contrast — ideal for dark content and cinematic viewing. Response times are also extremely fast at under 1ms.
02 Is the Asus ROG Swift OLED PG39WCDM good for competitive gaming? ›
✓ Yes. The 240Hz refresh rate is built for esports — it displays every rendered frame, reducing motion blur in fast games like CS2 and Valorant. The 0.03ms response time keeps pixels sharp between kills. FreeSync Premium Pro prevents screen tearing when GPU output fluctuates.
03 How good is the HDR on the Asus ROG Swift OLED PG39WCDM? ›
OLED delivers the best possible HDR — each pixel switches off for pure blacks while bright highlights stay vivid. The contrast is effectively infinite, which is impossible to achieve with LED backlight panels. HDR films and games look exactly as intended.
04 Is the Asus ROG Swift OLED PG39WCDM suitable for photo or video editing? ›
OLED panels deliver highly accurate colours and perfect black levels, making them well-suited for photo retouching and video colour grading. Shadow detail is preserved that LCD panels often crush.
05 Who is the Asus ROG Swift OLED PG39WCDM best for? ›
It is best suited for gamers, content creators, multitaskers. Check the "Who Should Buy" section above for a full profile breakdown.
06 What is the benefit of the 21:9 ultrawide format? ›
21:9 lets you run two full-width applications side-by-side — browser and spreadsheet, or code editor and documentation — without either window being squeezed. Compatible games and 21:9 films also fill the screen with no black bars.
07 Is the Asus ROG Swift OLED PG39WCDM worth buying in 2026? ›
Asus ROG Swift OLED PG39WCDM remains a strong option in 2026. 240Hz refresh keeps motion smooth for gaming, which remains relevant as 144Hz+ is now the expected baseline. OLED panel technology continues to improve and this model's infinite contrast holds up against newer options. Wide colour gamut coverage remains relevant for photo, video, and content creation workflows. Our benchmark score of 9.0/10 puts it in the top tier of its category. Before purchasing, compare the current street price against newer models at the same price point to confirm it offers the best value for your use case.
