Over the past few weeks I have bought both a desktop PC and a new monitor. When hooking the PC up to my old (LED) monitor, I got some strange flickering / colour-changing but this disappeared when I tried using a flatscreen TV (via both VGA & HDMI). I was a little concerned that this problem might re-appear on a new monitor, but was reassured over the 'phone that my warranty would cover this. I need not have worried, as the new (24") monitor works brilliantly. A few moments to fit the stand, hook up to the PC and re-set to 75hz (OK, and a few more to change the audio output to my headphones) and all is working brilliantly. Very happy to recommend L.D.
