Screen going off to the right
-
@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 ;
goes off screen, and negative if there is too much border
#overscan_left=16
#overscan_right=16
#overscan_top=16
#overscan_bottom=16uncomment to force a console size. By default it will be display's size minus
overscan.
#framebuffer_width=1280
#framebuffer_height=720uncomment if hdmi display is not detected and composite is being output
hdmi_force_hotplug=1
#force 800x480 resolution as this is non-standard for HDMI
hdmi_group=2
#hdmi_mode=1
hdmi_mode=87
hdmi_cvt 800 480 60 6 0 0 0uncomment to force a HDMI mode rather than DVI. This can make audio work in
DMT (computer monitor) modes
#hdmi_drive=2
uncomment to increase signal to HDMI, if you have interference, blanking, or
no display
#config_hdmi_boost=4
uncomment for composite PAL
#sdtv_mode=2
#uncomment to overclock the arm. 700 MHz is the default.
arm_freq=1000Uncomment some or all of these to enable the optional hardware interfaces
#dtparam=i2c_arm=on
#dtparam=i2s=on
#dtparam=spi=onUncomment this to enable the lirc-rpi module
#dtoverlay=lirc-rpi
Additional overlays and parameters are documented /boot/overlays/README
Enable audio (loads snd_bcm2835)
dtparam=audio=on
#gpu_mem_256=128
#gpu_mem_512=256
#gpu_mem_1024=256
#overscan_scale=1
core_freq=500
sdram_freq=500
over_voltage=2
gpu_mem=128 -
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.txtfile 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. This can make audio work in # DMT (computer monitor) modes #hdmi_drive=2 # uncomment to increase signal to HDMI, if you have interference, blanking, or # no display #config_hdmi_boost=4 # uncomment for composite PAL #sdtv_mode=2 #uncomment to overclock the arm. 700 MHz is the default. #arm_freq=800 # Uncomment some or all of these to enable the optional hardware interfaces #dtparam=i2c_arm=on #dtparam=i2s=on #dtparam=spi=on # Uncomment this to enable the lirc-rpi module #dtoverlay=lirc-rpi # Additional overlays and parameters are documented /boot/overlays/README # Enable audio (loads snd_bcm2835) dtparam=audio=on gpu_mem_256=128 gpu_mem_512=256 gpu_mem_1024=256 overscan_scale=1 disable_splash=1The 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 0Not 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.

@fulton1 Sometimes the best way to “cut the Gordian knot” is with a sword. In other words, redo your sd card with a fresh copy.
