Last week I was called upon to go help a person who was trying to do some computer graphics work and needed help with matching colors. Their computer and LED monitor was a few years old and was purchased separately, both were typical 'consumer' quality.

When I sat down in front of it and viewed some images I could tell that the display was umm…'something less than ideal'. I quickly checked the desktop graphics settings; everything looked correct. But then I spotted a problem, the computer and monitor were connected with a VGA cable. Both device support HDMI by the owner thought he would save some money and used his old VGA cable. A trip to buy a new cable and his display colors were greatly improved with the new HDMI cable.

Also note that if folks have been 'thrifty' when buying their monitors (and stamp collectors can sometimes be 'thrifty') that the less costly monitor are known to have poor color rendering. Like most things in life, you get what you pay for. This fellow had saved money when buying his monitor and I was able to demonstrate the short comings of his monitor using this link.

One of the take-aways of this thread is to be aware that even if you have a great expensive monitor that is properly calibrated, the majority of other users of this community probably do not. Posting color images and IDing basic colors/hues is feasible; but we should be cautious with any assumptions since we have absolutely no way to understand what someone else might be seeing on their screens.
