#3 Has this monitor been updated to support pbp? if not, does the lg osc software provide a similar function (control two computers from one monitor)?
The LG 34'' UltraGear Curved WQHD Nano IPS 1ms 144HZ HDR 400 Monitor with G-SYNC Compatibility, Model # 34GP83A-B is not designed as a monitor that supports PBP and cannot be upgraded to support PBP aftermarket. PBP (Picture-by-Picture) as the name suggests is a function that splits the screen in two and allows you to view two external video sources simultaneously on the screen, it does not allow you to control two computers from one monitor. The function that you are describing is LG's Dual Controller is a software that you need to download onto both devices attached to the monitor and lets you control both devices with just one keyboard and mouse. Both computers can be connected to the monitor via HDMI, DisplayPort, or a Thunderbolt connection just as long as at least one of the computers is connected via HDMI, and both computers must be connected to the internet because the computers are connected via an IP address. Regrettably, the 34GP83A-B is not compatible with LG's Dual Controller
