Hey. I'll be brief. I remember you making a little joke a while back about just going and setting up a browser-based WC, after adding a new function to your model viewer.
It got me thinking. If you have any interest in stand-alone projects, especially something that could potentially generate revenue, send me a PM. If not, don't bother; I just thought I'd put the initial offer out there for a discussion, of sorts.
1) How to change the resolution.
2) How to get the original resolution.
I am assuming that by original resolution you mean the native resolution of LCD monitors?
So when you search for information, you should probably search for these two questions separately.
Good luck
