Thesame thing goes for wireless mice, no matter how fast thelink is, they will ALWAYS have SOME lag compared to a wired mouse. These are the hard facts. Take them or leave them.
I have a mireless logitech mouse and keyboard, using older RF technology. Bottom of the line. I notice no lag (Though the click sticks if your over 4 feat from the reciever).
You get your facts straight. Wireless technology is faster then you can think or act.
However, I do agree: the nature of LCDs will most likely plague them with high speed game problems. However, some ARE alot better, and are capable of playing games on without too much of a problem. Granted, CRTs are better, but LCDs are pieces of crap in that spect anymore... besides, size could be his issue, and he needs to save space.
Blah... and I can't help. Sorry, don't know monitors well.
