Commander X16

The first pic is using 1:1 scaling

the second is 4:3 (or “aspect ratio scaling”)

This monitor is 1680x1050, so the 640x480 image looks pretty good scaled up. I also happen to run the text interface on this system at 640x480, and the picture looks perfect - the edges of the text are sharp, and there are no obvious scaling artfacts. My Ultimate 64 also looks great on this system; it also looks fantastic on my 54" 4K TV. 

This is not to brag about my great monitor - I'm just saying that modern hardware does a much better job than the ones made just a few years ago. 

@TomXP411 what version of Ultrix are you running or are you a VMS?

I haven’t actually dug into the software yet. I just finished the PiDP-11 build a few days ago, and I’ve set that aside until after I finish a few other projects.

This is so handy! What model is this?

I know that this features is just the monitor software (or should i say firmware), so it should be possible to implement all kinds of thing. For example, looking at this 1:1 picture, it would be great to add 2x zoom to this. Thus every source pixel would occupy 4 pixels of monitor (1 pixel -> 2x2 pixels).

Would your monitor surprise me doing that? )

This is rad!
