Enlarge / LG UltraGear 48GQ900. (credit: LG) LG is already an OLED TV king, but when it comes to PC monitors, the company's OLED offerings are scant. That's changing this summer with the LG UltraGear 48GQ900 announced this week. Just like LG's other OLED monitors, you can expect this to be a lavish display for those with extreme needs and large budgets. Aimed at console and PC gamers, the 47.5-inch OLED screen will have a 4K resolution at 120 Hz (overclockable to 138 Hz) and a 0.1 ms gray-to-gray response time.
