Having a difficult time matching color on my two monitors. #1 is Samsung S24E310 LCD. #2 is Samsung SyncMaster. Graphics card is AMC 7700 using the HDMI and DVI outputs. I've adjusted color until I'm blue in the face (pun intended). Too simplify, while neither monitor displays spot-on color, the poorest color reproduction follows the feed. In other words, a reddish tint on the HDMI feed on monitor #1, becomes the same reddish tint on monitor #2 if I switch the cable to that monitor. I finally bought an X-Rite ColorMunki Smile dual monitor calibration device. The results were no better and in fact, a little worse.
I've tried adjusting with both the Samsung controls and the Windows 10 calibration procedure. To keep consistent, I then made my own digital color calibration chart using Photoshop with bars of white, black, true red, true green, true blue, yellow, cyan, and magenta. Dragging this chart from screen to screen, the differences are obvious, mostly in the blues and reds. I tried changing the DVI cord. No joy. Have not changed out the HDMI cord.
So do I have a bad card or what? If so, any recommendations?
