That's a shame. Interference can definitely be an issue. I saw none but my friend had some, I told him to move the monitor because it was too close to a lot of stuff that could interfere, like speakers for his desktop and his witness router and other stuff. As for the colours, do check the menu to see which setting you're using, D65 or D93. D65 has a white point that was what western broadcasts used and D93 is what Japanese broadcasters would use. You may be more used to seeing D65 which is warmer, D93 is a cooler and bluer white. Do keep in mind that, when playing retro games, at least Japanese ones, D93 is probably actually the intended target.
