I have a HP Pavilion dv5 laptop which is just over a year oldand seems to have developed a serious display problem since I bought it.
I have only started using the HDMI port on this model since around october and notice I often get a terrible bug when using it.
i can be watching somethin gon a monitor via hdmi or simply have something connected to it and at random the screens (laptop and external) flicker on and off. I get the popup speech bubble style error in the taskbar saying a "Device Driver has Stopped Working"
Sometimes it recovers but most of the time the screen crashes as does any audio or anything else playing and a scattered mixed up mess of a screen gets locked into view. The only thing i can do then is restart the device.
