I'm after a 28" widescreen to replace my frustratingly poor 21" Toshiba, and while almost all the sets I've seen have been more than satisfactory in terms of picture quality, the constant high-pitched buzz that plagues my Toshiba seems to be unavoidable. I've seen some people mentioning that one of the main advantages offered by 100Hz TVs (and I'm really not at all bothered by 50Hz flicker) is the comparative lack of noise emitted by the componentry, but others sem to be of the opinion that 100Hz TVs are worse than 50Hz in this respect. So which is true, or are they both as bad as each other? I don't really want to spend the extra on a 100Hz set as even the basic entry-level 50Hz ones cost more than I'd like them to, but if it largely eliminates buzzing - which is undoubtedly the largest flaw I've identified in anything but the worst CRTs (such as my current one) - then I suppose it might be worth it in the long run. Any advice appreciated.
