A: Hello there, Aaron. We understand your inquiry regarding the power compatibility of your 39GS95QE-B monitor for your move to Malaysia. We understand that ensuring your equipment is safe to use in different regions is a significant priority for maintaining the longevity of your OLED display. Based on the official specifications for model 39GS95QE-B, the unit uses an external power adapter that supports an input voltage of 100-240V at 50/60Hz. Because Malaysia operates on a 240V power system, this monitor is designed to be compatible with that voltage range, and you will not require a separate voltage down step device or a different power supply. You will simply need a compatible power cord or a plug adapter to fit the Type G outlets used in that region. To ensure everything is ready for your move, we recommend a simple check of the label on your current power adapter brick to confirm it displays the 100-240V rating before your departure. Thank you for sharing your experience with us. Your feedback is important, and we'd like to assist you further to ensure your transition goes smoothly. https://www.bestbuy.com/product/lg-ultragear-39-oled-curved-wqhd-240hz-0-03ms-g-sync-freesync-premium-smart-gaming-monitor-with-displayhdr-400-true-black-white/JJ8VPZWY6X If you have any further questions about its features, please contact us on [email protected], and our team will be more than happy to assist you. —Renzo

Immersive Experience
Overall a beautiful monitor. One thing that was not really mentioned anywhere is VRR Flicker on OLED Panels (look into it if your thinking of buying OLED and no it’s not specific to this monitor). Other than that, this monitor is amazing.

Goldilocks OLED Ultrawide.
Written February 2026 for the 39” 1440p 240hz model, in White colorway for $800 US on a 50% off sale. Why 4 stars and not 5? Well, youve just gotta know what youre getting here and temper your expectations. If you think this is the end all be all perfect monitor, you might have your hopes too high. Theres a reason it was 50% off when I bought it, there are newer panels coming out this year that are pretty insane. However, if you think this might be the perfect large screen OLED ultrawide so as not to have too low of a PPI like the 45”, but larger (and more importantly taller) than a 34” ultrawide, you might be onto something. If youre looking for perfect text clarity as well as high framerate ultrawide oled gaming, you might be disappointed by the text clairty, but not necessarily the gaming performance. This monitor is a great balance between saturating my 5070 GPU at 1440p ultrawide 240hz without leaving either frames or resolution on the table if you opt for the new 5K2K, which im not even sure can be saturated by a 5090. Guess it depends on which games you play. But for me, this 39” monitor strikes a great balance, especially on sale ($800 US in Jan 2026).

Great display, but….
I wish it was desk/wall mount available and that it had better height adjustment options. Other than that, it’s great
