Hi everyone  
my setup specs  
device: WeTek Play 2  
cpu model: amlogic s905h rev c  
EmuELEC version: EmuELEC-Amlogic.aarch64-4.3-Generic.img  
monitor: eyoyo 16:10 inch LCD monitor 1280x800  
i could tell the image is cut off on the top and not looking right.  
i went into the emuelec.conf file and changed the

## Set video mode ee\_videomode=1080p60hz

to

## Set video mode ee\_videomode=1280x800p60hz

hoping that would fix the problem but it is still the same overscan screen  
any help would be greatly appreciated thank you everyone.

Udate i found a post on  
[Screen overscan · Issue #145 · EmuELEC/EmuELEC · GitHub](https://github.com/EmuELEC/EmuELEC/issues/145#issuecomment-602711944)  
so i launched terminal and put in these lines  
fbset -fb /dev/fb0 -g 1280 800 1280 1600 32  
echo 0 0 1279 799 \> /sys/class/graphics/fb0/free\_scale\_axis  
echo 45 25 1235 775 \> /sys/class/graphics/fb0/window\_axis  
echo 0x10001 \> /sys/class/graphics/fb0/free\_scale  
and after i put in them lines the overscan is gone in the terminal the screen is perfect.  
but when i exit the terminal the overscan comes back.  
i do not know how to save the settings to keep the changes.  
the post has 4 steps i can only understand 2 out of 4.  
and i cannot find the setres.sh file in emuelec on winscp.

SSH in, Copy the setres.sh to /emuelec/bin:  
cp /usr/bin/setres.sh /emuelec/bin  
Then modify the file to include the custom resolution.

Thank you so much Langerz82 for helping me. i am new to the hole inner workings of emuelec.  
i have tried what you said about copying the setres.sh file from /usr/bin to /emuelec/bin and  
modifying it with the lines i used in the terminal but its not working and l don’t think i’m doing it right

Also make sure you set 1280x800p60hz in the emuelec video settings (you might have to apply a custom setting), or for the emulator select native video and 1280x800p60hz if it’s there or just auto will use the emuelec setting.

Also paste the modified setres.sh file here:  
[https://gist.github.com/](https://gist.github.com/)  
and provide the link as the nested code seems to be breaking.

I pasted the modified file [emuelec 4.3 modified file · GitHub](https://gist.github.com/octopusgreen/d64b4f7461778592541353fc4196567e)  
I made a custom file in /usr/config/ called EE\_VIDEO\_MODE and inside of it i put 1280x800p60hz  
and also in /storage/.config/emuelec/configs file emuelec.confg i replaced

## Set video mode

ee\_videomode=1080p60hz  
to

## Set video mode

ee\_videomode=1280x800p60hz  
and auto is set for all emulators.  
Again thank you so much for helping me out Langerz82.

Maybe just also have in your code:

```auto
  1280x800p60hz)              
        fbset -fb /dev/fb0 -g 1280 800 1280 1600 32 
        echo 0 0 1279 799 > /sys/class/graphics/fb0/free_scale_axis
        echo 45 25 1235 775 > /sys/class/graphics/fb0/window_axis
	echo 1200 > /sys/class/graphics/fb0/scale_width
	echo 800 > /sys/class/graphics/fb0/scale_height
        echo 0x10001 > /sys/class/graphics/fb0/free_scale
        ;;  

```

I think that should be all. Oh hang on 4.3 might have the PATH order mixed up as there was a patch done to re-order it.  
If you do: echo $PATH  
it should be:

```auto
/emuelec/scripts:/emuelec/bin:/usr/bin/batocera:/storage/roms/bios/jdk/bin/:/usr/bin:/usr/sbin

```

If emuelec/bin isnt before /usr/bin then in you will have to modify the 99-emuelec.conf in the source and re-build to have near the top:

```auto
export PATH="/emuelec/scripts:/emuelec/bin:/usr/bin/batocera:/storage/roms/bios/jdk/bin/:$PATH"

```

But no change.  
I did the echo $PATH code in the terminal and this is that it showed

Big update it did work! The code you posted Langerz82 that i put into the modified setres.sh file  
Then dropped that file in emuelec/bin thru using ssh worked but i I didn’t see the changes until i went into something like a game or the terminal and then existed back to the main screen of emuelec then the overscan was gone.The screen  
stays normal untill i shutdown emuelec and when start emuelec back up the overscan comes back so  
I just need to into a game or the terminal again exit and its fixed. I’m Super happy it’s fixed i only i have to do that little thing to fix the overscan no biggie.  
Thank you emuelec.discourse.group and thank you  
Langerz82.

You can edit `/storage/.config/custom_start.sh` and add your commands there

and saved it and restarted emuelec but the code didn’t change the resolution.

lol no:  
try first setting the custom res by doing in ssh:

```auto
echo 1280x800p60hz > /storage/.config/EE_VIDEO_MODE

```

clear the contents of custom\_start.sh and just add:

```auto
/emuelec/bin/setres.sh $(cat /storage/.config/EE_VIDEO_MODE)

```

and that should switch to that res on startup. If in future you want to change resolutions edit the EE\_VIDEO\_MODE file for your other resolution.

</div>

sorry I should have said you also need the correct headers in your custom\_start.sh file.  
So you could either have in /storage/.config/custom\_start.sh file:

```auto
#!/bin/sh

/emuelec/bin/setres.sh $(cat /storage/.config/EE_VIDEO_MODE)

```

or alternatively if you want to use the Emuelec setting ee\_videomode in emuelec.conf:

```auto
#!/bin/sh

# load the profile script.
. /etc/profile

/emuelec/bin/setres.sh $(get_ee_setting ee_videomode)

```

All the best and good luck. ^-^
