Thank you. The article doesn't seem to address my problem. All three screens show what they should, but the color settings on the two additional monitors are off.
The gamma setting appears to be the problem. The menu of adjustments that is part of the monitor itself doesn't have this option. Also, when I use Windows to calibrate the colors (Settings, System, Display, Advanced display settings, Color calibration), there is a slider for gamma which works on the laptop but doesn't change anything when used on either of the added monitors. And as I mentioned above, when I go through Graphics properties on the Intel HD Graphics Control Panel, the added monitors do not adjust.
Any help would be appreciated.
For better understanding, please provide us the following information:
Is your laptop working with a 32-bit Operating System or 64-bit?
Are you using any type or video adapter to connect the monitors with the laptop?

Thank you for getting back to me!
Is your laptop working with a 32-bit Operating System or 64-bit? 64 bit
Are you using any type or video adapter to connect the monitors with the laptop? They are connected via SIIG USB 2.0 to VGA adaptors, Serial # SIIG APV2548X, part #JU-000071-S1
Please provide us:
Processor model: 6th Generation Intel Core i7-6500U Processor (4MB Cache, up to 3.10 GHz)
Laptop model: Dell Inspiron 17 5000 Series
Probably your adapter would not recognize properly your monitors, and it would generate graphics issues like resolution, video, colors; if there is another device in between your television and the integrated graphics controller, it will interfere with the onboard graphics controller's ability to properly detect the presence of your TV or Monitor.
I recommend you to use a straight-through cable, HDMI to HDMI or VGA to VGA.
