No, the monitor won't change with the windows open. It's its own light source, so it won't be affected greatly by another light source.
It's the PRINTS that will change.
I can't answer that, because you haven't posted any for me. Not any actual files.
Please don't think I'm denying there's a colour problem. I believe you. I just suspect it's due (at least in part) to the light in which you're viewing the prints.
I need you to know that I'm ignoring all the photos you've taken of your photos. Sadly, they're meaningless to me. It would be great if I could trust them, but I can't. Screens don't photograph well.
I just need to know the answer to my question.
You're not doing anything wrong, I assure you. That's just what the clone tool does. It's one of its shortcomings.

On modern screens, Contrast should pretty much always be left at the factory default setting.
It mightn't be a bad idea, just before your next calibration (which will be when you get the DVI cable) to find the "Reset factory defaults" button in your Dell's menu, to make sure Contrast is at default.
Yeah, it's fairly normal for it to be in the teens for those screens.
I'm so sorry to be a pain, but it's polite not to upload other people's photos directly. None of us would like it if we found out that other people were downloading our photos, then posting them elsewhere.
Can you provide links to them instead? So the photographers get the credit and traffic they deserve.
Thanks for understanding.
Yeah, it sounds bright. But gee, if you're having to go as low as 61 during calibration, to get a print match, that's a worry.
You said it's a Dell, right? What brightness setting do you have the Dell at, to get the 61 reading?
In answer to your question in your email (not mentioned here) yes, a DVI cable really can make a difference. No guarantees, but it is definitely something you should try if possible.
61 brightness is far too low. You need to get some more light in your room if at all possible.
Yes, and yes.
But PLEASE take the Layers & Masks Class as well, if you think you're lacking in that area. It's only a small & cheap class, full of very important fundamentals.
