1. Once the operating system (Win 7 Ultimate 64-bit, SP-2) of my PC shifts to sleep mode the monitor does not transition into power saver mode. Instead, it turns back on and a blank screen appears (no display of any kind). When this happens, a barely noticeable glow is visible with a slightly higher radiant level at the edges of the screen. When the system is commanded back to normal operation, the monitor remains in this condition (blank screen). Furthermore, the OSD menu will not work and cannot be activated via the front panel control button(s). The only way to restore the monitor back to normal (active screen) is to physically turn the monitor off via the front panel power button and back on again for the desktop to be displayed.
2. The same problem (blank screen) recurs when a power option is selected via the OS that turns the monitor off after a preset period of time.
3. Occasionally during system boot-up, the monitor doesn’t display an active screen as well and remains blank. The problem can at times be corrected by pushing and holding the front panel power button. However, when video reemerges and the display seems to perform normally, the power button and OSD menu is no longer operable and normal operation can only be restored when the power cord is pulled and reconnected.
4. Also during system boot-up, when the monitor doesn’t display an active screen and remains blank, the power button can immediately be rendered inoperable by the anomalous monitor control until the power cord is pulled and plugged back in again.
5. Yet, all of the above mentioned problems do not seem to happen when the monitor transitions to power save mode on its own.
Did you purchase the U3014 directly from Dell or from some reseller?
What posts are on the video card? What ports have you tested from the video card to the U3014.
Are you using the Dell supplied U3014 cables?
I purchased the monitor over the Internet from PROVANTAGE.
The U3014 is connected to a DVI port of my video card (ATI Radeon HD 2900 XT) using the DELL supplied DVI cable.
Before I purchased the DELL U3014, I used a 22 in monitor and operated it via the DVI ports of my video card as well. There has never been and still aren’t any problems with this particular monitor, video card, DVI connectors, or cable interface.
Chris: My ATI Radeon HD 2900 XT has dual DVI ports. I connected my new U3014 to either port with the same unreliable results. Conversely, my other 22 inch monitor has been and still performs perfectly well with this video card.
I paid good money for the U3014 and hoped to enjoy its superior performance. I also invested over $200 in an i1 Display Pro from X-Rite, because the U3014 requires it for correct color calibration. Once this odd display control behavior is resolved, I certainly will be pleased with its functionality and color presentation.
Finally got in touch with DELL technical support over the phone. They promised to fix the chat problem on their Web site and issued service request and dispatch numbers.
trichard68: My ATI Radeon video card does not have a 'displayport' and I am not ready to plunk down another stack of money for a new video card for the sole purpose of having an additional port to resolve a nagging DELL monitor internal hardware control problem. Moreover, my video card performs extremely well and it simply doesn't make any sense to replace it.
If the replacement monitor does have the same issue with that video card, it cannot be a monitor fault. Our U3014 uses DVI-D Dual Link ports and cabling. Perhaps the older Radeon HD 2900 XT ports are actually DVI-D Single Link?
Chris: I received the replacement monitor on Fri 8/9/2013. So, may I express genuine gratitude at this point for DELL’s customer telephone support and fast shipping?
Coming straight to the point, the replacement monitor performed perfectly well over the same DVI interface with my computer and did not exhibit any of the problems I inquired about by way of this forum. So, as clear evidence reveals, I bought a new U3014 monitor that was defective to begin with.
Now, I have to get used to the idea that my replacement monitor may actually be a refurbished unit and not a new one off the production line of the manufacturer. Then again, it might be worth mentioning that the replacement monitor is marked “Rev A03.” The faulty monitor, on the other hand, carries the mark Rev 01. Hence, it looks as if DELL may have been aware of subject problem(s) and implemented some changes.

So looks like Revision A03 was ninja'ed out...
@ Chris M: can you tell us what fixes were implemented in A03? Did it finally fix the problem with horizontal lines?
@zimocat: Did you see any anomalies like described bellow on your A03 display:
