Thank you for all of the information.
You should leave your new NEC monitor with its very accurate factory calibration. Use the multiprofiler app to choose the colour space the monitor is working in and to set the correct display profile on your computer. It is very unlikely that you can improve on the factory calibration for a new NEC PA monitor.
How do I get back to the factory calibration? If I simply calibrate at 6500k is that good enough? Or, there are a couple factory setup calibrations to select from in SpectraView as follows...
Photo Editing - D65, Gamma 2.2, Intensity 140 cd/m, Contrast Ratio: Monitor Default
Print Standard - D50, Gamma 1.8, Intensity 80, Contrast Ratio: Monitor Default
Do I choose one of these or should I choose one, then click Edit and select Native from the White Point drop down menu? I'm confused because I did this this morning and when I chose Native, it didn't allow me to enter an Intensity value that I wanted, I could only select Maximum Possible.
Onto my lighting situation -
I know most of you might cringe at me saying this but I'm trying to get screen-to-print matches in a room that is very uncontrolled as far as lighting goes. During the day, it's very bright in here, no direct sunlight in the windows but it's extremely bright because of a lot of windows. The room doesn't even have shades or curtains and to be totally honest, I used all the money I DON'T have to get this NEC monitor. Now reading that I need special lights and realizing I need to buy shades or curtains too is overwhelming me because I don't have any extra money to spare now. I also don't have an extra room I can move to, this is the only space I have to set everything up. I think what I'm telling myself is I'm just trying to get as close screen-to-print matches as I can for now. My goal is to get an online shop going to try and sell some fine art prints. THEN I would have the money for lights, etc. See how BACKWARD my crazy plan is??!? I thought the monitor was the last thing I'd have to buy in order to make this happen, besides of course paying for lab prints. (WHCC) I'm new to this whole color management world and I guess I'm just hoping to get very close screen-to-print matches for now somehow.
The thing that's driving me nuts is I measured the ambient light in the room I'm in and it changes all throughout the day. This morning, it was like 4700k, then yesterday at 4pm, it was around 8000k. I even started thinking, "well, maybe if I see the ambient light is around 5000k at one time in the day, then I can trust viewing my prints at that time of day when comparing them to the monitor." I know, crazy. Since I'm broke, is this nuts to do this temporarily?? Trust what my prints look like if the ambient light in the room is at a certain temperature during the day?
