OK Wojpen, thanks for your answer. I have tried many ways and still cannot get IGO to see the skin. Here is what my info.ini in skin file says:

supported_resolutions="1920_1080,1080_1920,1080_1845,1920_1005,1794_1005,1080_1701,1794_1080,1080_1776,1776_1080,1280_800,800_1280,1280_755,800_1235,1280_736,800_1205,1280_720,1280_703,800_1172,1280_674,720_1234,720_1280,1280_670,720_1230,1200_670,720_1134,960_540,540_960,960_502,540_922,888_540,540_888,854_480,480_854,480_762,800_442,480_800,800_480,800_448,480_768,800_435,800_440,480_755,480_760,800_432,480_752,740_440,480_710,1024_552,600_976,768_1184,1196_768,1280_752,800_1232,1280_755,1024_768,768_1024,1024_600,600_1024,1280_750,800_1230,800_444,480_764,800_425,480_745,1184_670,720_1184,1184_720,1196_720,1196_674,720_1138,1280_768,768_1280,768_1230,1280_718,720_1134,1196_670,720_1154,1204_670,720_1204,1204_720,480_320,320_480,480_295,1440_2392, 2392_1440"

I have this entry in sys:

[rawdisplay]
force_renderer="RENDER_MOYA"
driver=engine
screen_xy="1196_720:2392x1440/1440x2392"
;screen_xy="auto"
driver="gdi" ;for HD & QHD
highres=1 ;for HD & QHD

Have tried different combinations in the screen_xy with auto and resolutions scaled,and still not showing. The Resolution Utility says:
HighRes resolution: 2392_1440 Primo Resolution: 1196_720 pixel.

What is still wrong?
