Weird pixel problem with new Viewsonic VP201

Hi, I bought a brand new Viewsonic VP201s TFT monitor yesterday. I have noticed quite a lot (50+) flashing red pixels about 4inches in from the left hand side. They are not always visible, however you can see them with a hi-coloured background (the Bliss wallpaper in XP makes them very apparant) and also when playing DVDs and games. They don't seem to be dead pixels as they appear to flash (kind of like a firefly effect) however they are distracting and there is a lot of them. Also, they don't appear when the colour depth is set to 16bpp. Has anyone seen this before? Thanks
