monitor cables -DVI

What is the difference between dual link DVI and single link DVI cables? Would I see a noticeable difference if I switch to dual link cables? Would I benefit any at all from switching from single link to dual link?

Do you mean the actual cable or on the graphics card?

With the monitors listed in your specs you would see zero benefit other than a lighter wallet.

Digital Visual Interface - Wikipedia, the free encyclopedia

Dual-link DVI

To support display devices requiring higher video bandwidth, there is provision for a dual DVI link. A dual link doubles the number of TMDS pairs, effectively doubling video bandwidth at a given pixel clock frequency. The DVI specification mandates how the dual link may be used. All display modes that use a pixel clock below 165 MHz, and have at most 24 bits per pixel, are required to use single-link mode. All modes that require more than 24 bits per pixel, and/or 165 MHz pixel clock frequency must use dual-link mode. In modes where each pixel uses 24 bits of color data per pixel or less and dual-link mode is in use, the transmitter stripes pixel data across both links; each sequential video pixel is transmitted on alternate links. In modes with color depth greater than 24 bits per pixel, the second link carries the least significant bits of each pixel.

Thanks stormy13, I'll give it a good read. I also changed my monitors recently and updated my specs accordingly. Would it make a difference with the new monitors I have now?

The actual cables.

Still no. You would only need them if you have a 120 Hz monitor that requires dual link to run at 120 Hz. On 60 Hz monitors even if you use a dual link cable connected to a video card with a dual link port, you still wouldn't see any benefit as it will fall back to single link.

Thanks again...
