Our take on the LG 39 Inch UltraGear OLED WQHD 240Hz 0.03ms G-Sync Curved Gaming Monitor

The LG UltraGear 39GX90SA-W is a 39-inch curved OLED gaming monitor with a 21:9 ultrawide QHD panel, 240 Hz refresh and a 0.03 ms response time. OLED gives it per-pixel contrast and near-instant motion, with G-Sync and FreeSync support and USB-C, DisplayPort and HDMI inputs. It suits players who want an immersive ultrawide for fast shooters and racing games and also watch video on it. Against 34-inch ultrawide OLEDs it trades some sharpness for a bigger, more wraparound picture, and its 275-nit brightness is modest next to brighter mini-LED rivals.

Questions and answers

Is 240 Hz worth it on a 39-inch ultrawide?
Yes for competitive shooters, where the 240 Hz refresh and 0.03 ms response cut motion blur. For slower story games the ultrawide shape matters more than the refresh rate.
How does it compare with a 34-inch OLED ultrawide?
The 39-inch panel is bigger and more immersive, but 2560 x 1440 spread wider means lower pixel density. A 34-inch 1440p ultrawide looks sharper at the same resolution.
Is G-Sync supported?
Yes. It carries G-Sync and works with AMD FreeSync too, so both Nvidia and AMD cards can use variable refresh.
What is in the box?
The monitor, a power cable, an HDMI cable, a DisplayPort cable and a USB-C cable.
Can I mount it on an arm?
Yes. It uses a 100 x 100 mm VESA pattern, which helps because the monitor weighs about 39 lb.
Is 275 nits bright enough?
It is fine for a dim room, where OLED contrast shines. In a bright room with sunlight on the screen, brighter mini-LED monitors hold up better.
Where is the LG 39 Inch UltraGear OLED WQHD 240Hz 0.03ms G-Sync Curved Gaming Monitor cheapest?
