ubeswitch is a semi-smart solution for your Atari STFM/E/MEGA ST which adds:
* VGA connector
* Button for switching video mode and configuration (see blelow).
* 3.5mm A/V connector
* Volume control.
* Automatic detection and switching of resolution (requires software implementation).

Button functions:
* Short press (0.25-1.999[..] seconds): Switch resolution.
* Long press (+2 seconds): Save current resolution as default at cold boot.

Please note:
15KHz H-Sync capable monitor is required. Such as the one reviewed here viewtopic.php?f=30&t=309
Early ST models does not have 12V output on video port and thus cannot power the adapter.

Automatic detection and switching of resolution (requires software implementation).

What does this mean exactly? ST software needed? Or what... I can find no info anywhere... Thanks

Yepp. Software is under development, don’t know the status or who, except Troed, might be working on a driver.

Small demo:

Yeah it's still on my todo ... :/ It is a bit tricky.

For demo developers, no driver is necessary. It's common to edit in high res, then disable VBL, switch to low - run the demo - switch back and enable VBL again. Works perfectly fine with the auto switching adapter :)
