Using dvi port on dimension 9150


I have a new machine with a video card with an analog port and a digital port.  I just pluged in the digital cable from the flat monitor to the machine but no video came up. it came up normally when plugged the analog port.

So in the display control panel, under settings there were two sets of settings for two displays but they were both the same video card, so I change to the second one  and that worked but when I unplug the analog cable there is no video.

What am i doing wrong, I assume I should be able to use just the digital cable?

Thanks very much for your help.

Hi Sky,
It sounds like you may have to setup the LCD monitor to receive signals from the DVI connection. Is there a menu for the monitor to change that setting? What are the monitor specs?

Ok got you.  It is a dell ultra sharp 20 in.  I will look at the settings on the monitor.

Thank you.

I'm not sure if this is your model, but I supplied a link for changing the input. The manual for this model claims it will automatically switch if no input is detected, so the problem may be elsewhere. The second link is for a different 20" Dell monitor, perhaps one of the menus are similar to what you have. Although Dell's support site is excellent for PC's, it lacks a bit when it comes to monitors, as I couldn't find the Ultra Sharp 20".

Did you get a driver cd with the monitor? If so, did you install it? Dell usually takes care of any drivers for your system, but the monitor may need specific drivers. I checked your manual for the 9150 and can't seem to find the answer there. There doesn't seem to be a BIOS setting specific to this issue. Are you using a PCI express video card that came with the system? Do you know the specs on the card? It may possibly be a specific setting from the video card, but I'm guessing (if you get no video at post), it has to be more basic at the BIOS level or within the monitor settings itself. If you have no luck, calling Dell is probably a good idea, as it's not impossible that the port is faulty (either the card or the monitor). There may also be a compatibility issue with the monitor and the video card (I've heard of some nVidia issues and DVI outputs to some monitors)  but I would assume that Dell would not sell incompatible items together.
If you have another DVI cable, try using it.  You might have a bad cable.
