I've googled this a bit, but have yet to find anything.
I have 4 monitors. when I lock my screen via win+L, it turns 3 of them to the background color selected in background options, and the 4th one is the windowsXP login screen. I want to know if it's possible to make a background picture appear instead (right now the picture is actually my default background, I just want it to carry over when I lock my machine.
