DVI Cable bad? (1 Viewer)

[Jeremy_Watson]

I recently purchased a 2m DVI-D cable from RAM Electronics to connect my HDTV cable box to my Sony HDTV since I ran out of component inputs. However, since I've been using it (approx a week) I've noticed some strange artifacts that I hadn't seen before. To be more specific, sometime blue horizontal lines shoot across the screen, blue pixelation can been seen in dark area and I get a lot of image flicker.

I will probably be returning/exchanging the cable, but I wouldl ike to stick with a DVI input due to limited inputs. Has anyone else experienced problems like this, because I've heard DVI can be bad over longer runs, but I'm not sure this is how those problems manifest themselves. Also, is there some easy was for me to check that it is the cable and not my TV or HD box?

Thanks for your help,
Jeremy

Any comments? Does this just sound like a bad cable?

If you use a component input do you see the same artifacts? If not then it is either the cable, cable box or TV. Start by swapping then out in the easiest order and see if it goes away. Depending on RAM electronics return policy it may be easiest to start with the cable or cable box. Are there multiple DVI settings on your TV? A Sharp I was working with recently had DVI Analog video, DVI Digital video, DVI Digital PC and DVI Analog PC. If you have DVI settings on your TV try playing with them to see what that does. I am assuming that you are using DVI-D
