Mame display area the same regardless of resolution?
<< < (2/3) > >>
Malenko:
are you enforcing the aspect ratio in your config? ( -ka in command line, theres a check box under the video tab for it)

if there are black bars on the side the ratio is being enforced. Its mostly the monitor 4:3 ratio (or 3:4 for vertical) thats being enforced. What happens when you rotate the output?

It looks like "Screen -> View -> Pixel Aspect" is what I need.  Seems to do the trick after a few tests, but may not be suitable for all games (Frogger seems to have a crazy aspect ratio for example).  I will eventually be running this on an LCD, not an arcade monitor.

Now, is this preferred for authenticity?  I am actually unclear on how the original games work.  If the original title was using a (4:3) monitor (which I assume most were?) did it have black bars if it wasn't running at 4:3 resolution, or did it stretch to fit the screen anyway?

Are you using directdraw, or direct3d? How about Hwstretching?
Also, what resolution is your monitor running at natively? Does it have a stretch to screen, or a 1:1 pixel mode?
VanillaGorilla:
Pixel aspect is usually the nicest option, in most cases, on a modern display. Some games can look squished because the ppi is denser than an older crt display. I just adjust those that I think look wonky by choosing an alternate aspect, or use the slider controls to adjust the image size manually, mame saves your changes from the video menu. In the end, you are the only person you have to please, just do what you think looks best.

Are you using direct3d with scanlines overlay (ScanRez2 is the best overlay in my opinion) ? its quite authentic looking...

I've tried that on mine, and at a res of 1920x1200 it absolutely destroys performance, plus the lines look super thin/sharp. I've thought about creating a new graphic with a higher res so it doesn't have to redraw the graphic nearly as many times, but haven't gotten around to it. Honestly, I couldn't say exactly what authentic arcade monitors should look like because I'm too young, and my memory of it has no account for any scanlines present in modern/semi modern games. (been going since maybe 86?)
