I realize it's Windows that's handling the 2 monitors, and there are several settings... which mostly I don't fully understand yet. With random Windows monitor settings changing, I managed to get one monitor doing one thing, and the other monitor showing what was being done, and a mouse pointer that would not travel from 1 to the other, and had to switch cables to get control & display back to the same monitor.
I've looked at DisplayFusion, and for me, it adds another layer of non-understanding & complication to my set-up. Maybe when I figure out how to get the Windows settings as good as they can be for my setup, and if I find it lacking, I'll see if DF will do something I need. Like Adrian, I'd rather not have 3rd party applications unless there's an overwhelming need.
The video card is an XFX brand, model FX-775A-CGFR... an AMD Radeon HD 7700 series. I bought it in November of 2013. Here's a link if you want the specifics about it. http://xfxforce.com/en-us/products/all-previous-gpus/amd-radeon-hd-7750-core-edition-fx-775a-cgfv
I'll get it figured out. I'm just slow at things right now... Been sick for 3 months with some respiratory virus thing that JUST. WON'T. GIVE. UP. so I pretty much always feel like I've been awake for 24 hours straight. I'd take a nap, but I'd wake up just as tired and be that much further behind.
Thanks for the input!
