RP4 Screen not centered

[logic1208]

hi there
i have a rp4 4gb with elcrow 5" tft.
the manufacturer of the tft gives the config:

#ELCROW TFT
#hdmi_force_hotplug=1
#max_usb_current=1
#hdmi_drive=2
#hdmi_group=2
#hdmi_mode=1
#hdmi_mode=87
#hdmi_cvt 800 480 60 6 0 0 0
#dtoverlay=ads7846,cs=1,penirq=25,penirq_pull=2,speed=50000,keep_vref_on=0,swapxy=0,pmax=255,xohms=150,xmin=200,xmax=3900,ymin=200,ymax=3900 display_rotate=0
#ELCROW TFT END

which works very well!

the mainscreen where you see the different emulators and all menues works just fine.
some emulators like psp, lynks, amiga, neo geo, sega dreamcast works also perfectly.

but some other emulators psx,sega gamegear, snes, sega master system, sega genesis, game boy, there is the screen off center. i just see the top left corner of the game.
i have tried overlay, on, off. diffrent settings with aspect ratio... but nothing works.

andy suggestion?

thanks,

andy

Please add some info about your system, as detailed in https://retropie.org.uk/forum/topic/3/read-this-first.

Looking at your configuration, all specific TFT display options are commented out (# is a comment start, anything after is ignored). Can you post the entire config.txt on pastebin.com and then provide the link here in the topic ?

Main_Screen ( Screen is OK )

Some of the Working Emulator ( Neo Geo )

One of the off center Emulator ( Game Gear )

You screenshots haven't been uploaded - you can edit your post and upload them again if you want.
Looking at your config.txt, all the options for the TFT are commented out, so they are not applied. You should probably have something like

#  ELCROW TFT
hdmi_group=2
hdmi_mode=87
hdmi_cvt 800 480 60 6 0 0 0
dtoverlay=ads7846,cs=1,penirq=25,penirq_pull=2,speed=50000,keep_vref_on=0,swapxy=0,pmax=255,xohms=150,xmin=200,xmax=3900,ymin=200,ymax=3900 

# ELCROW TFT END
