Screen going off to the right
-
I thought it worked because the boot text looked fullscreen... but nope
-
though what worked? You haven't told me what you have tried.
Please also provide details of exactly what you have changed, including any overscan settings you tried.
-
i was messing around with the overscan, i have made that many changes i cannot name them all, been in config.txt and configure retropie in the settings
-
you will need to provide actual details or I can't help. At least an example of what overscan you have tried - or what screenmodes. Perhaps you are not even doing it right, but without an example I'm afraid I won't be able to help futher.
-
@fulton1 Can you send me some info about your screen and the controller board that drives it? Manufacture name and any and all numbers on the back. Maybe take pictures of it and post them here. I have some limited experience with this type of screen.

@glennlake Sorry man i have no idea, i bought it from ebay
I am gonna paste my config.txt:

@fulton1 OK.. This is only a guess but you could try to change the following lines:
"disable_overscan=1" should be commented out
"#hdmi_force_hotplug=1" should be uncommented out
The line: "force 800x480 resolution as this is non-standard for HDMI" should be commented out
"hdmi_mode=1" should be commented out as it is in conflict with the next line "hdmi_mode=87"(this line should be OK)
That's all I can come up with for now. Give this a try. Good luck :-)

no change whatsoever, my config.txt now looks like ;

Its weird because the boot text looks perfect
-
Your boot text is cut off also. Look at the second line of text. Can you post a link to an eBay or Amazon listing for the screen you bought?
-
@Douggernaut the tablet is was made for is a Medion Lifetab E7310 , the resolution of the screen is 1024 x 600

@fulton1
I have a similar screen with identical resolution.

Hope this helps!

@Douggernaut Didnt make a difference bro, if anything it moved it further to the right, ive lost 2 days to this damn screen :/ BUT the text at the start is no longer cut off!!!!!
EDIT:
it is cut off, i thought it hadnt because the font size shrunk
-
Pics of the controller board incase itll help anyone in anyway, shape or form
-
this is my controller board. Below is a pic of the back of the board:
-
@fulton1 OK.. I found a link to the manual for this controller card but I don't think this will help. "http://www.elecrealm.com/down/html/?40.html" It looks like the only way you can change the resolution of the screen is to use a PC with a parallel port and a cable. No luck :-(
-
@glennlake So nothing can be done ? :(
i did have another screen in this card before and it was PERFECT ( i broke the screen by forcing it into its place :(
So it might be the screen?
-
@fulton1 he night be able to force a custom res to whatever the board is set too. You can do custom modes on the rpi to a degree. Maybe an edid dump would help
-
@BuZz i have no idea what an edid dump is bro
