No, my version of the card doesn't have a mDP ouput. It has the reference model outputs as you stated. So when I have the monitor hooked up via DisplayPort or miniDisplayport, I'm using either the mDP->DP cable supplied with the monitor, or a regular DP to DP cable I bought. I don't blame you...

HDMI cable obtained. If I see another seemingly non-caused blank-out, Imma try it. BTW you guys are awesome. Thanks for putting up with this seemingly endless tale of woe. I don't think I ever want to buy a Dell monitor again. :P

I've had a grand total of maybe two months of trouble-free use of my last (third warranty replacement!) U2715H. Not really even that long, as I was out of town for two weeks in December. Now in the last week, it's starting to go blank again. This time around, it's only black for perhaps a...

There does seem to be a general problem with Ultrasharps over the last few months. When I initially researched my problem with the first one - what turned out to be a simply broken miniDisplayPort input - I found at least two other threads on the Dell product forums where someone was having...

Wanted to bring this thread fully up to date. I am now on replacement monitor #3. It is still hardware revision A02, but this time everything works. Here's a synopsis so you don't have to go digging through the other threads: The last monitor I posted about in this thread proved to...

I wouldn't be so sure about that. The only thing that would be different if I had bought via a brick and mortar store is...nothing I can think of. I'm not at all surprised that I found at least one other person having problems with multiple defects...

Received monitor #4 on Friday (11/6). Also hardware revision A02. So far so good. No physical defects noted, all ports seem to work. The only feature I was unable to test was Multi-Stream Transport, that thing where you daisychain 2 or more monitors via DisplayPort. It seems you have to...

No, there's nothing broken off in the port, it's just that the metal socket is so poorly aligned with the hole that you can't plug anything in. It looks as if the black plastic casing has a sort of flange or tab that is meant to rest against the outside of the metal USB socket, positioning it...

I've been through a few graphics driver updates, a new video card, and even an entirely new OS (Windows 10) since I originally purchased the monitor in June, so I think if that had been the issue, I'd have fixed it by now. Good point anyway. I noticed that when I had three monitors hooked up...

Monitor #4 is supposed to ship soon. If that one is also defective, I will press the issue of a refund with Amazon. I emailed them about a refund after the second monitor (first replacement) proved also defective, but they never got back to me. Next time I'll get on the phone. I don't know...

Dell is replacing the monitor yet again. This will be monitor #4. Shipped monitor #2 back this afternoon. Maybe they'll get it right eventually.

OK, this has gone from annoying to just plain ridiculous. I've had the second replacement monitor hooked up alongside the last one for a couple of days. As I've had time I've tested various aspects. So far, good news: -no dead pixels -no uneven light/dark spots and best of all...

Second replacement monitor received. Haven't had a chance to try it yet.

Replacement cable did not help. A second replacement monitor is supposedly on its way.

Another replacement monitor is supposed to be on its way soon. Maybe I'll get the mythical hardware revision A03 and the mDP input will finally work.

Dell must have overnighted the new DP-to-mDP cable, because it was waiting for me when I got home. So either I now have a third defective cable, or the mDP port on the monitor is bad, because I still get no picture when using the new DP-to-mDP cable. Not even after turning the computer...

Commodore64, have you had a resolution to your situation? I may have missed it but I just re-read the thread and it sounds like you still don't have a working display. Buying my own DP->DP cable "fixed" my display, but if the new cable arrives and I still can't use the mDP input, I'm doing...

Just got a ship notification on the new cable. That was faster than I expected.

Thanks! The really surprising thing is that I seem to have received two defective DP-mDP cables in a row. Either that, or the mDP input in the monitor was defective on the first one. Possibly the miniDP port in the replacement monitor is also defective. I've seen other Ultrasharp owners...

Update: Never did get satisfaction using the miniDP input. Eventually I got sick of messing with Dell tech support & shelled out for my own regular DP to DP cable. Life has been good since. Further details in my own thread here: http://hardforum.com/showthread.php?p=1041922544#post1041922544

OK so after several extended discussions with Dell tech support, they've agreed to send me a new DisplayPort-to-miniDisplayPort cable. It will be interesting to see whether my problems were merely the result of a bad DP-mDP cable. Still doing fine with the regular DP-to-DP cable I bought. If...

Been using DP to DP cable for about a week. Display is A-OK. So it seem either I got two bad MiniDP cables in a row, or else two monitors with a bad miniDP input. Annoying. I'm not thrilled that I had to buy my own cable to fix Dell's issue, but meh. At least it's fixed. Pretty dang awesome...

Borrowed an HDMI cable. So, this is what it's like to have a properly working display. I guess I must have a bad mini DP port on the monitor, or the cable included with it was defective. Again. Anyway, with the HDMI cable, the monitor works exactly as it should. Also, display quality is...

Ok looks like I might be able to borrow an HDMI cable from a friend this weekend. If the monitor works that way I guess it at least could prove that the Dell-supplied cable is bad.

I don't have an HDMI cable or any other DisplayPort source, so I've done all the troubleshooting I can.

Had a chat. They were ultimately unhelpful. Said they didn't want to send out a replacement monitor or even just a replacement cable because they couldn't figure out where the problem was. Well no kidding, neither can I, except I'm fairly sure it isn't the video card since I replaced that and it...

FWIW I am having almost exactly the same problem with my U2715H. The only difference is that in my case, for a few weeks the display would work at least some of the time. It would go blank randomly and boy was that annoying. As of a few days ago I get no picture at all, and only occasionally...

Yes, the whole situation is a mess. Since I started this thread, things have gone from bad to worse. Now, the monitor won't display any picture at all, no matter how much I turn it on and off, plug and unplug things, or reboot or turn the machine off and on. The most I can get it to do now...

Doing a clean Windows 10 install over the next couple days. Well see whether it makes any difference.

That's correct. I have received replacements for both video card and monitor.

No, I had a GeForce 560Ti, but sold it after I got the new monitor. Both the older monitor (Samsung 1920x1080 on DVI) and new one (Dell 2560x1440 on DisplayPort) are connected to the new video card (GeForce 970). One GPU, two monitors.

I had it hooked up by HDMI with my old video card since it didn't have any DisplayPort outputs, but the picture quality was bad. It would run at 2560x1440 but the image was fuzzy. I was surprised at the greatly improved picture quality when I first used DisplayPort after I got the new video...

So I'm sitting here with my second Dell U2715H monitor and second video card (GeForce 970), after RMAing both, yet I still don't have a usable display. The first U2715H was worse, but it's only a question of degree. The replacement, despite being hardware revision 01 (original was rev. 0)...

True, the unfortunate part is that my laptop has a really lousy Intel wireless device that maxes out at 75 Mbit/s. Ugh. So, whenever I want to transfer a large-ish file in a timely fashion, I must plug in. Someday I'm going to buy myself a really nice laptop with a dual-band wireless card...

Thanks! I might just do that! Call this one "solved."

Finally, somebody gets it! Yes, that's pretty much the situation. The DSL modem does have its own routing & switch functions. It hosts my network printer. However, I can't use it for my desktop machine. The desktop doesn't have a wireless NIC, and is physically too far from the DSL modem...

Because I don't have a cable long enough to connect the modem to the router wired. Thus the whole point of the question. If it were that simple I'd have already done it.

Is there any way I can get a router (Netgear WNR3500v2) to connect wirelessly with a DSL modem (Zyxel C1000Z) which also has wireless connectivity, so that I can ultimately access my Internet connection through the router? So far I can't make it work. The WNR3500 does have a "wireless...

I'm sure it impedes airflow somewhat but it hasn't caused the slightest problem with cooling. I don't overclock, however, so it's not as if I need maximum airflow anyway.

It would be a crying shame to use that build with a low-res monitor. With that kind of budget, you can easily afford at least a 16:10 monitor (1920x1200) or even one of those crazy new 1440-line monitors.
