Maybe a bit presumptuous, but we might be able to help. In my opinion, the type of panel matters much more than the manufacturer. If you Google a display, you'll often find out what sort of panel it's utilizing.
TN: Typically, the least expensive panel. TN panels tend to have poor viewing angles, so are best for small displays (especially wide screen TN panels can be awfully discolored in one corner or another from any viewpoint). Many TN panels are so-called "6-bit" panels and have poor color accuracy (though, depending on the dithering implementation, some are more noticeable than others). My recommendation for gaming.
MVA/PVA: Modern non-dithered MVA/PVA panels offer good viewing angle, good color reproduction, but slower response time and they're slightly more expensive than TN. My recommendation for movies. (I use a Samsung PVA LCD as monitor number two alongside my Mitsubishi Diamond Pro CRT. Very nice, but not the best for gaming.)
IPS: Great color reproduction but lesser black levels compared to MVA/PVA. Depending on the implementation, refresh rate may be as good as MVA/PVA panels. Generally found in fairly large displays because they're not inexpensive to manufacture. My recommendation for graphic arts. (I suppose there are dithered IPS panels around, but I haven't seen one. Avoid them.)
That's not the say that the manufacturer doesn't play into this at all. They all tend to have different "dead pixel" policies and features (like adjustable stands). My personal recommendations for an everyday budget are Samsung and Viewsonic.
