Hi there, I have just bought an Iiyama ProLite E431S (which is very nice by the way). One thing I have noticed, every so often I am getting some 'lines' like you would get on a TV that has a poor reception. It seems to come and go and so far I haven't been able to figure out any pattern. At the moment, I am connecting through the D-SUB input on the monitor (which is an analogue connection). It does have a DVI-D input which is digital. I suspect I will get a better image there. Can anyone tell me what I need to make this connection? Is it just a new cable that connects to the graphic card, or do I need something else? If you need any specs, I have an NVIDIA GeForce2 MX400 card. Thanks!
