Dizzy Spells

Since starting work at the ACU and using a Iiyama AS4636D TFT LCD display I have started to get dizzy spells. I have now had 4 occourances where I lost my balance for about half a second. Three of these times where in front of the screen and one was while walking down the road just after work.

I have been taking regular eys breaks and trying to read up on what might be causing the problem and if its a common complaint but so far I have not found any concrete evidence. I have also tried to fiddle with the settings but unfortunately I am using Linux so I cannot use their test.bmp program to see if I can set the screen up correctly.

Its a shame because the monitor is the dogs danglies but it just dosn't seem to agree with me.
