I have picked up some type of virus which has changed the way I am able to view the pixels of my monitors. I run the 64bit Ubuntu 12.1. I have tried every resolution setting combination on 4 different monitors from a 32 inch (which worked just fine prior to this problem) to this tiny 17 inch monitor. The look of the monitors is very fuzzy and makes it seem like you are wearing a pair of glasses prescribed for someone else. It is very nauseating. I believe it was from downloading free art but could be from web browsing or maybe inspecting elements of how other have set up websites. I have more than 20 sites I have built or am in the process of building of which I am handling.
After 5 days of trying to solve this problem I suspect that it has something to do with the video card input (maybe).
One of the monitors said you do not have the correct graphic or video input (or something like that) to run this monitor. I have a brand new computer t-seris Azrock motherboard with 32 gig DDR3 ram, with AMD A4-3400 APU with Radeon(tm) HD Graphics × 2 processor, 2 gig sparkle PCIe 2 video card and 2 terra byte hard drive with 650 power supply. So it has plenty of computer to do what is needed. I have tried every setting combined with every setting on every monitor. I have tried HDMI connection and VGA connection with all of the computers and all of the monitors on my network.
I worked with CenturyLink for over an hour ( finally got someone in the U.S. after being routed through the Phillippines for more than an hour) and I have worked with the guy who build the computer for over 3 hours to solve this problem to no avail.
My monitor worked great for over 3 months then one day all 3 computers in my office went to this odd and very problematic pixelated look 5 days ago. It is like being seasick using this computer.
It has affected every monitor on my network including my older XP Pro system.
By the way I really like Unbutu. I very much rely on my computer to make a living so I need to fix this problem.
One thing to note is it always says "graphics- unknown".
