What does "two-way display connectivity" mean in a description of a display port to DVI cable?

Jan 7, 2013 6:55 PM

I'm struggling with connecting my second monitor to my new computer at work (and having to do it on my own, as this is a personal monitor).
The monitor is a Dell E1909WDDc. It has a hard wired (non-removable) display port cable. My new computer, due to an upgraded graphics card, can only take a DVI input. (Yes, that's weird and it's correct and verified by multiple computer alpha-geeks in my area).

I have the correct connectors get the display port cable into the DVI port on the computer but it still doesn't work. The computer won't detect the monitor. The monitor just flashes different colors. Tried rebooting, etc. The current theory is that the display port to DVI adapter is one-way...with the signal coming in the DVI end and going out the display port end (I need the opposite).

I found this cable on Amazon: http://www.amazon.com/gp/product/B002CSUZSU/ref=ox_sc_act_title_4?
Does anyone know if this will work with the signal coming from the DVI end?

If not, any other ideas?

I'm sorry but I think that you may be SOL here. I haven't messed around with Display Port technology very much, but I'm 99.9% sure that in order to use a monitor with DP input you NEED a DP ouptut. I know it works the other way around, DP out to DVI/HDMI in, which is what the adapters are for. Maybe someone else has a better answer for you, or knows something that I don't.

If not a new video card offering Display Port technology may be your only option.

I did a little digging and came accross several websites that confirm my previous comment. Display Port's FAQ has your question listed first and foremost. Your only cost-effective solution is to buy a video card with Display Port technology. I guess DP outputs at a much higherGood news is decent video cards w/ DP can be bought for around $50 on most tech websites like newegg.com

Good luck, and sorry I couldn't have given you a more optimistic answer.

P.S. Dual Mode is another version of Display Port technology that allows for downconverting to DVI, HDMI, and VGA signals. So again it can only downgrade the signal to a lower quality, not the other way around.

@j5: Yes, it's the same issue. But I have a bit more information now and figured if I just updated the previous question it would be less likely to be noticed.

Not a farewell, just a forced redirect.

It's true, Local.Woot is no longer, but please don't despair.

Never-ending savings are still to be found on Deals.Woot each and every day, so come on in. Don't think of it as a time for tears. Think of it as a way to bring us all closer together under one roof.

Sorry

This is only for people who have bought woots

We restrict voting to users who have purchased something from one of the other Woot stores. It's not just because we want your money (which we do) - it's the best way to be sure all the votes are coming from real people and not spam-bots or phony accounts. The best way we can think of, anyway. For now.

You can always get voting rights by buying something from one of Woot's other sites:

Purchases through Deals.Woot don't count, because in that case you're not buying anything from us. And we don't have your account information for those purchases.

If you think you've bought something from Woot before and still can't vote, make sure you're logged in with the same account you used to buy from us.

Geez, why so negative?

You have to vote up more before you can vote down.

Don't get us wrong. Negativity has its place. And downvotes are just as essential as upvotes when it comes to making Deals.Woot a useful place to find deals.

But when your votes lean so heavily toward the dark side, we have to wonder. Go vote up a few things. Accentuate the positive for a little while. It'll do you some good, and it'll do the site some good, too. Then you can get back to dealing out the smackdowns, OK?

Too late, we all heard you!

Hmm... you're wanting to take your vote back?

Well, that's a bit tricky. See, we do a lot of stuff with your vote, using it to work out the popularity of what you voted for, compare that to all the other things voted on, tally up our leaderboard, work out your reputation. Someday we'll do a little cartoon showing just how hard your vote is working.

Anyway, taking votes back messes all that up, so we give you five minutes, in case you just mis-clicked. After that we've got to say no take-backs. Luckily, votes are free, so feel free to throw them around left and right wherever you see fit.
