I'm currently using a Belkin Pro 3m DVI lead to connect my PC (Radeon 9800Pro) to a Viewsonic VP171 LCD monitor. I think it's dual-link, but I don't have the spec to hand. It connects the two together far more easily than the old 1.8m lead that was barely long enough, but after a while red "sparklies" tend to appear on screen. I can get rid of them by reselecting the monitor's input (don't know why this works) but it's a pain. Can anyone recommend me a lead upgrade that should fix the problem? I noticed that Lindy leads seem to be well thought of hereabouts, but the nearest size I could find at tvcables.co.uk was 5m. And it seems a bit strange to be changing to a longer lead when trying to solve this problem! Any suggestions? Thanks in advance.
