Is DVI-D on its way out? Is it for losers? Was it always?
So five years ago I took it into my head to have a work station in one room and a home theater in the other, both running off the same computer. I am pleased to be at a point in life where, when I ask the landlord for permission to do something, he always says yes, because he is me.
So I drilled through the floor where the PC/TV screen is and ran a humongo 25 foot DVI-D across the basement ceiling all the way into the other room where I drilled another hole in the floor and brought it up to the monitor. Mouse and keyboard were to be hooked up through the monitor. Now this was no ordinary DVI-D cable, I special ordered it, it had some kind of booster.
Well this rig has always worked in terms of showing the display in both rooms, but there were from the beginning issues with both mouse and even keyboard lag. One of my earliest posts here was on this topic. Eventually I got a separate 25 foot USB line for the mouse and connected it directly to the PC. The keyboard lag I just lived with.
So the years go by and I have a number of issues with my recent rebuild. Along the way I have had many discussions here and with the people I know, who have some knowledge of what I'm trying to do. The local non-internet talent suggested that my problems with the RX 590 Nitro might be cable related (repeated crashing during benchmarks). Well, the RX 590 had already left the house on an RMA but I said OK, I'll try a new cable, and when the RMA comes back it will have a new cable to talk through.
The cable is here first. This time I got a 25 foot displayport 1.2 (looked for 1.4 in this length, couldn't find it). Anyhow I hooked it up and now no more mouse lag and no more keyboard lag. Who knows, perhaps also the graphics card issues are/were related to the same issue, though the old graphics card never faltered with the old set up (R9-380 Strix). That experiment remains to be run in the next week or so.
But never mind that, I very much wish that I had moved to displayport a long time ago. I'm kind of banging my head on the desk about it. If I read the specs right, the difference between gb/s between DVI-D and displayport is only about 10%, I never would have expected it to make a difference in my (unorthodox) build. Regardless of what happens with the eventual new graphics card, this displayport is noticeably better for the build.
I'd kind of like to know if anyone else has any "the problem was in the cables" stories so I can know what to be on the alert for. Should we as users be on the alert for the development/release of new cables? What makes cables go bad? When do we turn to cables as the issue in diagnosing a persistent problem? In my case cables were pretty much the last thing on the list. I didn't even think of it till I was reminded by others. When you look at the cables inside the case and out, that's a pretty significant diagnostic hurdle, in terms of sheer numbers.....
