Summary 08603: Screen Position/Stretch options won't extend beyond system's original screen size
Description Using the Screen Position and Screen Stretch sliders to move or expand the picture will hide anything that's beyond the initial screen dimensions.
Steps To Reproduce - Load any 4:3 system while using a 16:9 monitor (hharry) or, alternatively, a vertical game in a horizontal monitor (pacman).
- Open the sliders menu with the tilde key.
- Move the screen horizontally with the "Screen Horiz Position" (or vertically, in vertical monitor games) or stretch it with "Screen Horiz Stretch" and you'll see that part of the screen will be hidden, even though there's still some free space being used by the slider itself.
Additional Information I know this makes sense when windowed, but maybe it should use the full screen space when MAME is running full screen?

I can confirm your observations. It makes sense that you could push the picture over to the left or right side and expect it to remain whole, however I'm sure there's some technical reason why it can't happen.

That’s what it’s supposed to do. It’s like adjusting the size controls on a CRT TV – you can’t see any part of the image that you push into the overscan area.
