Help External Display Orientation

Looby

Lurker
Hello all. Im Looby.

Im new to this forum but have been a "low tech" android user for several years.

I have an LG Optimus G Pro stock rom not rooted or anything.

What i am trying to do is hook my phone up to an external display in my kitchen to display recipe webpages while cooking. Hookup is physically managed by a slimport adapter running to the display via HDMI. External display is hung in portrait orientation.

Problem is I cant for the life of me get the monitor to display correctly. When the phone is in portrait mode I get the massive black bars on the side of the image. I guess that is because i need the phone screen to stay in portrait mode but display in landscape mode on the external display. Not really sure if that makes sense or not. No amount or changing of the phone screen orientation fixes it as I think I need two different orientations one on the phone and a different one on the external display. If i leave the phone on auto rotate and go from portrait to landscape for a second it is correct and switches to a full screen portrait orientation on the external but then goes into the landscape mode and everything is wrong again.

Anyone know if there is any type of solution that might work? I have tried 4 different screen rotate apps and all just do the same thing and dont help. I know that if I were to hook up my windows netbook i could change the orientation of the displays independently and was really hoping this is possible in android.


I appreciate any help or direction anyone can provide.

Hi and welcome to the forums. Yeah you want your phone to stay on landscape mode to display correctly on the TV but I don't know why it isn't staying that way.
I doubt if this app will help but I've been using it to stop the screen from rotating without my permission. Check it out and if it doesn't work I'll get my thinking pants on :thumbsupdroid:

Sorry if I'm not understanding your problem ;)
 
Sorry I just read that the external display is hung in portrait (long sides, short top and bottom)?
Why lol?
Id say that's the source of your problem if so but have no idea how to fix it (other than to rotate it lol) Sorry
 
OK, I get it.

You're trying to get screen mirroring to come out the same as a portrait display word processor by rotating the big screen.

So you don't want landscape rotation at all.

You just want a 90° portrait rotation...
