FAQs
What is the difference between G-SYNC Compatible and native G-SYNC?
G-SYNC Compatible uses VESA AdaptiveSync technology to reduce tearing without requiring NVIDIA's proprietary chipset. It provides excellent performance for gaming and is compatible with GeForce GTX 10 series and newer cards. The 39GX90SA-W supports G-SYNC Compatible alongside AMD FreeSync Premium for universal VRR compatibility.
Is the 39GX90SA-W suitable for competitive gaming?
Yes. With a 240Hz refresh rate and 0.03ms response time, it meets the performance requirements of competitive esports titles. However, the ultrawide 21:9 format is not supported by all competitive games; check your title's native support before purchasing.
Can I charge devices via USB-C while using the monitor?
Yes. The monitor includes 65W USB-C power delivery, allowing you to charge laptops, tablets, and mobile devices whilst simultaneously using it as a display. Note that the USB-C port also handles data transmission and power delivery simultaneously.
What are the advantages of OLED for gaming?
OLED delivers infinite contrast ratio, perfect blacks, and exceptional colour accuracy. For gaming, this translates to superior visibility in dark environments, faster perceived response times due to perfect black levels, and vibrant HDR performance. The 1500000:1 contrast ratio of this panel is significantly higher than LCD alternatives.
Does this monitor work with older gaming consoles?
The monitor has two HDMI 2.1 ports, which support current-generation consoles (PlayStation 5, Xbox Series X/S). Older consoles may require HDMI adapters depending on their output specifications.
What is DisplayHDR 400 TRUE BLACK certification?
VESA DisplayHDR 400 TRUE BLACK certification indicates the monitor meets strict HDR performance standards including peak brightness of 400 nits, true blacks, and colour accuracy. This ensures HDR content is displayed as intended by creators.
Is factory colour calibration sufficient for professional colour work?
The 39GX90SA-W arrives factory calibrated and offers excellent colour accuracy (DCI-P3 98.5%). However, for mission-critical colour work, professional calibration using dedicated hardware (e.g., X-Rite i1) may be recommended depending on your specific requirements.
What is the warranty and support period?
The 39GX90SA-W includes a 24-month manufacturer warranty. Additionally, LG has committed to providing security updates until 31 January 2029, ensuring the webOS system remains secure.
