I'm planing to buy monitor Asus 24" VK248H LED and UPS APC BR900GI. Waveform type of BR900GI isn't "true sinewave" its "stepped approximation to a sinewave". I don't know if this monitor requires "true sinewave" for working properly when powers go out but if does will connecting it to Apc BR900GI going to harm monitor in any way? Will i have problem during power failures because of that? Buy the way i don't have the money to buy smart(pure sinewave) APC's UPS and i don't wont to buy CyberPower and stuff like that. That's why i'm asking is it safe to buy and connect these two.Thanks in advance.
