External Monitor Problems Only When Lid Closed
I have a brand new XPS 15 that is experiencing an unusual issue. I have two external monitors connected: one via HDMI and one via a DisplayPort->DVI converter. Both work absolutely fine while the laptop lid is opened (it makes no difference if the laptop display is disabled or enabled). However, if I close the lid and click on the Network icon in the system tray, it will disconnect both external monitors for a brief time and then reconnect them. This is reproducable in 100% of the cases, with the only difference being if the lid is opened or closed.
This wouldn't be that bad if that was the only instance, but I also occasionally experience these drops at random times. I'm thinking that it might be correlated with a notification coming through or something in the system tray popping up, but I'm not sure. As you can imagine, it's frustrating to lose your monitors for 3-5 seconds at a time. I have downloaded and applied all up-to-date drivers for the system, and have changed various power settings with no effect. Any help would be greatly appreciated.
