I have been suffering eye strain and nausea for some time now. I have gone through several monitors in a short space of time and am at my wits end. Now my research has suggested that I should be looking for a non-flickering LED backlight monitor with an S-PVA, P-MVA, or IPS panel. I'm after 24" or slightly larger. I understand Dell claim their LEDs don't flicker (nice!) so here I am, looking for the monitor to get me back to work!! Any ideas anyone?
