I have an Acer VN7-591G with a broken screen. I'd like to use it with a monitor attached to HDMI. However booting it will only display the Acer logo on that screen. I have no relevant options in the BIOS menu (which does display normally on the monitor when pressing F2 at boot). I've also tried to use the keyboard toggle, but that doesn't work.
Oddly I have been able to use the monitor in the recent past. I would boot the laptop and after 30 seconds or so I'd connect the HDMI cable and I'd be okay. For some reason that doesn't work anymore.
Does anyone have a clue how to solve this?

Ahh, by 'broken' you mean it has no screen after logo. Are you sure it's the screen, and not something else? I mean, it displayed the logo, so the screen seems to work. I'd look to getting to safemode or recovery mode, or whatever Acer uses. It might be gfx drivers, lack of power to boot to / view Windows and so on.

Unfortunately after booting I only see the Acer logo on the HDMI screen. Nothing else. I have no way of determining that Windows has booted correctly. Hence I have no access to Windows settings... I've tried the keyboard toggle (Fn + F5) but that has no effect.

Thanks for your help! No the laptop screen was very much dead alright. I connected the external monitor via HDMI and that shows BIOS (after F2) or (if I do nothing) the Acer logo. Since the laptop has functioned normally (with the external monitor) after the incident that killed the screen, my assumption is that the hardware is okay. But that's just an assumption ofcourse...
