@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. Here is the entirety of my/boot/config.txt
file which works for me.# For more options and information see # http://www.raspberrypi.org/documentation/configuration/config-txt.md # Some settings may impact device functionality. See link above for details # uncomment if you get no picture on HDMI for a default "safe" mode #hdmi_safe=1 # uncomment this if your display has a black border of unused pixels visible # and your display can output without overscan #disable_overscan=1 # uncomment the following to adjust overscan. Use positive numbers if console # goes off screen, and negative if there is too much border #overscan_left=16 #overscan_right=16 #overscan_top=16 #overscan_bottom=16 # uncomment to force a console size. By default it will be display's size minus # overscan. #framebuffer_width=1280 #framebuffer_height=720 # uncomment if hdmi display is not detected and composite is being output #hdmi_force_hotplug=1 # uncomment to force a specific HDMI mode (this will force VGA) #hdmi_group=1 #hdmi_mode=1 hdmi_group=2 hdmi_mode=1 hdmi_mode=87 hdmi_cvt 1024 600 60 6 0 0 0 # uncomment to force a HDMI mode rather than DVI.

The important part is here:
# uncomment to force a specific HDMI mode (this will force VGA) #hdmi_group=1 #hdmi_mode=1 hdmi_group=2 hdmi_mode=1 hdmi_mode=87 hdmi_cvt 1024 600 60 6 0 0 0
Not sure why but yours is configured for 800x480.
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
-
-
@herb_fargus Thanks, still have no idea what to do.
-
@fulton1 I'm on phone, so can't link. But search for raspberry pi edid dump and you will find how to do it.
-
Looks REALLY complex, i think ill just try and send it back for my money back.
-
@fulton1 welcome to Linux my friend ;) you're either neurotic like me and will spend weeks on a seemingly simple problem and be ecstatic when you finally figure it out or you'll just buy something known to be supported in the first place and save yourself the headache ;)
I find the problem solving to be rewarding as that's what the pi is all about but sometimes it can understandably be frustrating
-
What will i do about the config.txt? since ive done all kinds of crazy shit to mine.
