My $0.02. I think any tv you buy nowadays at, say 47" or bigger, can benefit from some sort of picture adjustment. It can be as simple as an Accurate Picture Adjustment using one of the many excellent calibration disks, AVS HD-709 (free), WoW, Spears & Munsil, DVE, etc. All tv's are going to have at the very least brightness, contrast, sharpness, aspect and color which can be set with any of the mentioned disks. And some tv's can show a marked improvement in pq by just setting those to standards. More advanced features such as CMS, 10-point grayscale, etc will require meters and special software so they can be truly calibrated. You can do that yourself but the cost in hardware and time learning is only something you can determine the worth of. But, as with all electronics, specs shift overtime so re-calibrating or re-adjusting periodically will be necessary. A professional or DIY calibration, depending on the tv, can last a couple of years but that's not guaranteed for all tv's even within the same model line. Whatever tv you choose to buy, I'd break it in for a period of time and if you want to tweak the settings, I'd first try a disk for accurate adjustments. If YOU are satisfied with the pq, you're done! Minimal cost and easy to re-adjust if necessary.
