Okay, all the requested technical details about my setup are below, but here's my problem: last week, I purchased a tablet monitor. I already had a dual-monitor setup, and I decided to just add this in as a 3rd display, rather than retire one of my existing ones, since the tablet needs to be closer to the front of the desk than the regular displays, and it can lie almost flat when not in use. I figured hooking it up wouldn't be a problem, since I had open ports on my video card. Unfortunately, it turns out that my particular video card can only handle 3 monitors if at least 2 of them are identical displays connected with the same type of cable, and, as you can see, my monitors are all different (I acquired them progressively over several years), so I can only plug 2 of them in to it. Well, I do have the on board graphics as well after all, I thought, once I'd figured out the problem, and I won't need the second regular display for the high-power stuff my graphics card does anyway, so I shifted the LG monitor to connect directly to the motherboard. All was well at first, until I realized that the LG monitor was displaying everything oddly - color is displaying in bands where shading and gradients appear, rather than showing smooth transitions. As best I can tell, it's displaying in 24- - or possibly even 16-bit color depth, despite reporting that it is using 32 everywhere I can find to look. It displayed color fine when it was on my video card, so I have to assume something's weird with the Intel Graphics? I have not tried plugging it in with HDMI instead of DVI because this monitor does not have an HDMI output, and I do not have a DVI-HDMI adapter.
I hope to replace my video card with one that can handle all 3 displays eventually, but I'd rather wait for a sale of a good one than pay list price right now, so soon after the new lines released. In the meantime, I'd like all my screens to display color properly if possible. Can anyone help me out?
