No power save in Dell 2007FP monitor
I have a Dell 2007FP monitor with firmware version A04 at work running
from a Dell Optiplex 755 computer and using a VGA cable. It enters "power save" mode (with amber lights) when I turn off the computer. I bought a refurbished Dell 2007FP monitor for home use. It has firmware version A02, running from a Radeon 9000 video board and using a VGA cable. It does not enter "power save" mode when I turn off the computer. I have to turn off the monitor when I turn off the computer. It also has no "DDC/CI" line on its Display Settings menu, although it is On in the Test menu. Are these features of the A02 firmware? Is there anything I can do to get the "power save" feature to work? My previous monitor, an AOC CRT, entered "power save" mode when I turned off the computer. It had no power switch. |

Do you have the latest drivers for the 9000 card? Power options are usually included in these. |

Well according to the documentation it states: If you have VESA's DPMS compliance display card or software installed in your PC, the monitor can automatically reduce its power consumption when not in use. This is referred to as 'Power Save Mode'*. If activity from keyboard, mouse or other input devices is detected by the computer, the monitor will automatically "wake up". http://support.dell.com/support/edoc...P/en/about.htm But your problem isn't a driver problem or even an OS one. As it should power down itself when the computer powers down. Now I thought how they do this is when the video signal is lost, then the monitor enters power saving mode. Although looking at the VGA pinout, there is 3.3/5v pin too. Which is supplied by the computer. That could be used to trip the monitor into power savings mode. So try this, disconnect the VGA cable while the computer and monitor is running. Does the monitor now go into a power savings mode? As it should as the computer now has no control over the monitor at all. If it is still on, then it sounds like the monitor's power saving features are not working correctly. You know, a stray bit can really cause a problem with digital circuits. You can try leaving the monitor unplugged from the AC and the computer overnight and try it again the next day. As that might be all it is. Another thing which comes to mind is I had some VGA cables that works fine on some monitors and not others. So if you had another cable that would be worth a shot. Now I am thinking that maybe some didn't work because some cables don't use that 3.3/5v line. Another thought is, are you sure it isn't entering power savings mode? As doesn't the power light go from green to yellow when it does? And sometimes green and yellow lights look a lot alike. I have a couple of Toshiba laptops and green and yellow looks very much the same on them. -- Bill Alienware M9700 - 1GB - Two Nvidia 7900GS running in SLI mode |

I brought home the 2007FP from work, which I know goes into Power Save mode (amber lights, no floating "No VGA Cable" window) when the computer power is turned off at work. At home it acts like my own 2007FP -- green lights and a floating "No VGA Cable" window window - no Power Save mode. Both monitors act alike at home. Even the DDC/CI item is missing on both monitors' Display Settings menus at home. The item is there at work. So the problem seems not to be in my monitor. The same thing (no Power Save mode) happens when Windows power management turns off the display at home, and when I disconnect the VGA cable with the monitor power on. It could be a cable or driver problem. I will see what happens when I use the VGA cable from work or a DVI cable. If that does not help, I will try installing a new driver, which was unnecessary when I changed from a Sony LCD monitor to the 2007FP at work. I still am using whatever driver I installed for the AOC 7K1R CRT monitor 8.5 years ago. My computer at work uses an ATI 2400 Radeon Pro video card. If all else fails, I can try installing a spare Asus AH3650 Silent video board. Russ |

If all else fails, I can try installing a spare Asus AH3650 Silent video board. Russ I tried a DVI cable. It worked okay on both monitors. The DVI cable also improved clarity of the display and size of the BIOS screen. Clarity was good with the VGA cable at work but worse on the same monitor (but different VGA cable) at home. Both monitors were slightly fuzzy with the VGA cable at home. Adjusting the pixel clock with the VGA cable helped but did not clarify everything. The BIOS screen display was also slightly (5%?) large with the VGA cable, but okay with the DVI cable. The DVI cable has fixed the problems but I wonder why. I suspect the VGA cable at home is second-rate. It came with my refurbished 2007FP monitor. But its Direct Data Channel (DDC) seems to work because I can identify the monitors' serial numbers using the VGA cable. I will take the VGA cable to work and check it out with that computer and 2007FP. I don't know how a monitor distinguishes between a disconnected cable and a powered-down computer, but it does not work with the VGA cable that came with my refurbished 2007FP monitor. Russ (again) |
