Hello Mounir, I have the same problem as described here. I am using version 1.26.24 on a laptop with a screen resolution of 3200 x 1800. In the BIOS I can not set anything, so my hope is the configuration of the Boot Loader. Here is a portion of the PlatformInfo file: <graphdevices count="2"> <graphdevice index="0" modes="7" h="3200" v="1800"> <graphmode index="0" h="3200" v="1800"> <graphmode index="1" h="640" v="480"> <graphmode index="2" h="800" v="600"> <graphmode index="3" h="1024" v="768">...
