Hi guys.
I currently have an 8800GTX feeding two monitors (identical three-year-old budget 19" 4:3 LCDs with DVI-D/VGA inputs) over the cables which came with the monitors, which are two-metre DVI-D single-link cables. My main PC unit is quite far away from the monitors, and the cable between the furthest monitor is stretched to its full length and is taut. So I cannot have any more distance between that monitor and the PC, which suits me fine, because everything is perfect anyway.
Things have been working well this way for years.
I have ordered two Dell 24" widescreen LCDs to replace the 19" monitors. So before they come, I need to get this cable situation sorted out, which basically means I need a longer cable to reach the added distance caused by replacing the 19" with the 24".
The cables that come with the Dell monitors are both also 2 metres long, so it is clear I need to buy a new cable.
I happen to have (for some unknown reason) a 5 metre DVI dual-link cable, and a 10 meter DVI dual-link cable, which I thought I could use. Both cables are quite thick and chunky, though I know this is no proof of quality. In tests:
1) the 5 metre cable syncs with the current monitor, but the display is very corrupted. Colours come out wrong, and all visual edges (mouse cursor, lines in the wallpaper, icon text etc) are surrounded by hundreds of red pixels.
2) the 10 metre cable doesn't work at all. Monitor doesn't get sync.
Now, this is evidently due to signal loss of some kind, but what is the most likely cause?
1) low power output from the card (8800GTX)
2) lousy cables
3) insensitive receiver in the monitor
4) dual-link cable into a singe-link monitor
My best guess is that the cable (low quality) is to blame, but I do not have another DVI-capable monitor to test on. The cable, however, is really thick and chunky - much thicker than the standard 2 metre cable that works.
The thing is I don't want to go and buy an expensive three or five metre DVI cable if I am still going to suffer image corruption.
Any ideas?
Thanks for any help. I would like to have all necessary cables in place before the new monitors arrive.
