I've got a quite expensive LCD monitor (~$1000) and I wish to protect it from instabilities in the power line. So I intend to get a UPS for it.
I see two types of UPS devices which differ on the output waveform - it's either a stepped approximation to a sinewave or a pure sinewave (rather expensive SmartUPS series). I've heard stories that some devices are intolerable to a non-pure sinewave and their power units just burn out for some reason.
Can anybody tell me whether it's a good idea to attach an expensive designer monitor to such a UPS with non-sine output or better grab a more expensive one which generates a pure sinewave?
