Overview
Gamers who want immersion over everything else will notice the LG 45GX900A, a 44.5-inch curved OLED at 3440 × 1440 and up to 240 Hz. The 800R panel responds in 0.03 ms and covers 98.5% DCI-P3, and USB-C with 65W is built in alongside two USB-A 3.0 ports. Two HDMI 2.1 ports and a DisplayPort 1.4 handle video. It is heavy at 13.5 kg and has no speakers, but DTS Headphone:X helps headset users. If your desk can take its 13.5 kg, it gives a cinema-like feel that smaller OLED monitors cannot match.
