G510 output bios to external monitor

Hello! My lcd broke and i'd like to use an external monitor, but i can not get it to dislapy bios on it. I have tried disconnecting the lvds connector from the motherboard, tried both hdmi and vga, tried closing the lid after pressing starting it and no luck. Is there a solution to that?

Re: G510 output bios to external monitor

That is an interesting problem that I've not thought about...

I would start by heading over to Control Panel - Display first. I'd try swapping the secondary display with the Primary display, moving it from #2 to #1 -anything?

Also, the Multiple Displays tab offers a few options, Duplicate Displays, Show only on #1 or #2 Display - anything?

I'm not sure if the Windows Key +P (project to a second screen) works while in the BIOS - anything?

I hope you post back should you find a fix.

Unfortunately the BIOS (POST) codes and hardware check output is to the primary (LCD) notebook display. Once it hands off to the OS then you can start showing it on different outputs.

If you can, try the scree swap function button (use FN plus the right button) to switch outputs.

Also - if it is just the LCD panel, you can find those pretty cheap now online, just make sure it fits (connector and resolution) before you purchase.
