GPi Case 2, Screen slightly to high / offset

[sheeep]

Hello, thats my first RetroPie project and it works pretty well so far. But i see that in EmulationStation the screen is a little bit too high so i got a small black border below.
I tried to set overscan, even the Dot by Dot instructions in the Documentation but it doesnt change anything. I only need to adjust the screen a few pixels down. Left and right are okey. Do you have any suggestions?

RetroPie v4.8
GPi Case 2 from Retroflag

Did you choose a different resolution from runcommand menu ?

Also, did you uncomment the overscan settings? They must be like this :

#disable_overscan=1

overscan_left= add your value 
overscan_right= add your value 
overscan_top= add your value 
overscan_bottom= add your value 

Positive nalue = smaller screen
Negative value = bigger screen

You have to restart for the chnage to take effect.

thank you, i got it. Screen is fixed.

But when RetroPie boots with connected charging cable the screen looks like above again. Thats weird.
On battery all is fine..

Is strange indeed, i don't understand why charging affect this. I checked the web site here : https://retroflag.com/gpi_case_2.html, when you are saying that you are charging it, do you mean in the docking base? Maybe in the docking state it output a different resolution.

Try to comment this line in the config.txt file :

from overscan_scale = 1 to be #overscan_scale = 1 to see if it make any difference.

It looks also, that web page offer a display patch for RetroPie, do you have install it ?

It does make no difference. Display patch is installed too. But the problem is no longer so important to me. But thank you very much =)
