How to tell if DVI dual link is being used
Commander Kinsey wrote:
How can I tell if my monitor is using DVI dual link or single link? I'm interested because I will be connecting it with a longer cable and if it uses dual link, the distance is greater without needing a booster. I'm running Windows 10 and a Benq FP2091 monitor. Can't find this info in the monitor specs online, or in my graphics card utility (MSI Afterburner), or in Windows display control panel, or the utility GPU-Z. It's a 1600x1200 monitor, so single-link DVI. They could put a dual on it, but "links cost money", and a single-link is sufficient. Single link = 1920x1200@60Hz CRTrb Dual link = 2560x1600@60Hz CRTrb (Reduced Blanking, reduces the flyback period) Paul |

I'll just have to wait and see how good the image is over the 10m cable. Different websites have different opinions on how far you can transmit at full data frequency - anything from 5m to 15m. At 1600x1200 I'd be near full frequency. I can't turn the refresh rate down on the monitor, and I don't want to reduce the resolution, so I guess I'd have to get two 5m cables and put a booster in the middle. |

I'd try the cable first, before panicking. I wasn't panicking I was just interested. As various websites I've read say if you are at the 165MHz limit, the length of cable must not exceed: Some say 5m Some say 15m One guy said he'd done 20m with a very good quality cable. There's an amp you can buy which claims you can run a 60m cable, then use the amp at the far end to pick up the poor signal and recreate it. And then apparently use another 60m cable then another amp, ad infinitum. |
