Hi, i have a question, sorry my english

For example, i have this resolutions

640x400@70hz
640x480@60hz
720x400@70hz

My windows dektop is 720x40070hz

If i use "fullresolution=640x400" no problem, all games use this resolution at 70hz

But for example, for Pinball Fantasies i need to use 640x480@60hz, but dosbox ALWAYS use 70hz, dont chante to 60hz

Opposite works well, for example, i use 640x480@60hz for my desktop, and use "fullresolution=640x400" dosbox change to 70hz

Any ideas? my desktop is 720x400 but some games like Pinballl Fantasies run at 60hz, and i cant see any way to force dosbox to change HZ "down" only "up"

I create some unique resolution like 642x480@60hz to try to force dosbox to use 60hz, but still dosbox force 70hz (desktop HZ) even to this resolution

Thanks
