Questions & Answers
Is there a 5k version of this same monitor with the same options... Operating system and ability to game without PC or Console? Also is there a 52 inch version with the same options?
Answered by LG Digital Customer CareCurrently, LG does not offer a standalone 52-inch productivity- or business-class Ultrawide™ monitor outside its gaming division. If you want a screen of that exact size from LG, the LG 52-inch UltraGear™ evo, The World’s Largest 5K2K 240Hz 1000R Curved Gaming Monitor, Model # 52G930B-B is your only option. If you love the exact physical footprint and deep 800R curve of the LG UltraGear™ 45" WQHD OLED 240Hz 0.03ms G-SYNC FreeSync™ Premium Pro Gaming Monitor with DisplayHDR400 TRUE - Black, Model # 45GX90SB-B, LG offers premium 5K ultrawide monitors that are completely separate from the UltraGear gaming lineup and are designed specifically for professional productivity and business environments. Instead of the gaming-centric "UltraGear" branding, these business and creative displays are sold under the LG UltraFine™ or standard LG UltraWide™ banners. They swap out flashier gaming design elements for professional features like sleek metallic finishes, cleaner cable-management stands, built-in KVM switches, and extensive enterprise connectivity like Thunderbolt 4 or Thunderbolt 5. If you want the extra widescreen workspace of a 5K2K (5120 x 2160) resolution similar to the physical footprint of the 45GX90SB-B, you can look at the LG LG 40-inch UltraFine evo™ 5K2K WUHD Nano IPS Black Monitor with Thunderbolt™ 5 PD 96W Model # 40U990A-W, or the LG 40" UltraFine™ WUHD 5K2K Nano IPS Monitor with Thunderbolt™ 5 and USB Type-C®, 40WT95UF-W (Commercial / Desktop Model), but neither of these is an OLED panel...^Ivan.
