I have a Samsung RV511 laptop, and recently my screen broke. I connected an external screen and it works fine, but only after Windows starts.
I want to be able to use the external screen right from boot, in order to set the BIOS to boot from DVD, and to then install a different OS and also format the hard drive. Right now I can only use the screen when Windows loads.
What I've tried:
- I've tried opening up the laptop and disconnecting the display to make it only find the external and use the VGA as default -- didn't work.
- I've tried using the Fn+key combo in BIOS to connect external display - nothing
I've been looking around for ways to change boot sequence without entering BIOS, but it doesn't look like it's possible.
Possible solutions?
- A way to change boot sequence without entering BIOS?
- Someone with the same brand/similar model to help me blindly keystroke the correct arrows/F5/F6 buttons while in BIOS mode to change boot sequence?
- A way to force the external display to work from boot, through modifying the internal connections (I have no problem taking the laptop apart if needed, please no soldering though), through BIOS or program?
Also, if I change boot sequence without accessing external screen, would the Ubuntu 12.1 installation sequence attempt to use the external screen or would I only be able to use it after Linux is installed and running?
I'd really appreciate help, I can't afford to fix the screen for a few months from now, and I'd really like to make my computer come back to decent performance! Thanks in advance!
Are you using VGA or HDMI? HDMI typically is a little better on the whole auto-detection side of things(two way protocol). Its possible the remove the ribbon cable between mobo and display will cause the bios to see no internal display and failover to the external. – Linef4ult – 2015-09-20T16:47:48.870
You could try while booting to hit the correct key to enter BIOS, regardless of whether you're getting a picture or not, wait a bit, then use the Fn + F key function to toggle from laptop screen to external. – harrymc – 2012-10-26T15:52:41.827
I mentioned in the question I already tried that. Thanks though – casraf – 2012-10-27T19:12:12.620
