My post - it's gone...
That's what happens when you leave the computer and walk off, allowing Aktungbby to stick his foot in the door and post a greeting...
Anyway, kikinado - go to the game folder with SH4, and right-click on the SH4.exe file. On the resultant context menu, left-click on "Properties" at the bottom of the list. Click on the "Compatibility" tab. Down towards the bottom of that tab is a "Change high DPI settings" button. When you click on it, it will open a new little dialog. Click the lower tick box, "Overide high DPI scaling behavior." Leave the dropdown set on Application. OK, OK, etc., and try to run SH4 again. It might also be that if it is already ticked, you have to put it back. Kind of depends upon the card, the driver, Windows, and where Aquarius is in the night sky... tic - You could also try "Run this program as an administrator", but it will give you another UAC pop-up to deal with each time...
One thing about this 10+ year old game is that it is beyond "legacy" as far as Windows is concerned. You ~have~ to install the DirectX v9.0c that came with the game. The reason being, that DirectX10 and on do NOT have some dll file(s) that SH4 needs to run the 3D portion of its little world. Installing an older DirectX over what you have will not overwrite the newer install, but will put the needed file(s) in-place...
Not only that, but with an LCD display monitor, you ~should~ use its "Native" resolution in Windows, and hope that SH4 will display one that matches it in its Options menu. That way, all displays fine... usually... There are other little things to try in THEBERBSTER's link.
Now, as a little side note, my Win10 laptop updated today (does this ~never~ stop??). One of the newest "features" I've now found in Windoze, is that when I fire up SH4, Windows will now minimize the game (seemingly arbitrarily), and pop-up this little dialog in the lower-right corner that says "Hi! This is Cortana! While you were in the game, this happened..." What I wanna know, is who is this "Cortana" chick, and why is she shelling out to Windows with my "legacy" game running, thereby ruining its "environment"?? (Another little treat from "legacy" games is that they expect an uninterrupted "stream" of computer use - Win10 doesn't like that, I guess)...
