I've been running two computers off of the 1800FP for some time (one on the analog side, the other using the DVI input - I toggle between the two with the front panel switch). Suddenly, the analog side stopped working. I've tried: 1) a brand new VGA cable 2) hooking up a different computer
There is a very faint glow on a black screen when I activate the analog side. The computer hooked up to analog can detect the presence of the monitor, and system preferences can be selected, but the display remains black. The DVI side works just fine.

Any contemporary monitor is able to switch analog/digital mode automatically if connection from signal source to monitor is set up properly.
Connect digital output from your graphic card to DVI input of the monitor. Disconnect any other signal cables from monitor and switch on both devices (PC & monitor). Wait a while. Monitor checks its inputs and a activates digital DVI, because it is only one active input on it.
If none picture excluding error message of monitor is displayed, go through these steps: 1) Check whether your monitor is set for automatic input selection. If monitor buttons have no response try to use analog input to activate screen (any picture, desktop background...) and then get monitor menu access by pressing menu button.
2) Find out what connector type has your graphics card in PC. Possibilities are: DVI, HDMI, DisplayPort and some their options. See Wikipedia for connector look if you are not sure. Remember that blue D-SUB (VGA) connectors are analogue and you cannot activate digital mode through analog VGA cable.
3) Use appropriate cable to connect monitor to PC. Example: Your PC has HDMI output. Use HDMi-to-DVI cable. Your monitor input is DVI and common DVI-DVI cable is not suitable in case you have PC with the HDMI. Note that DVI-to-DVI, DisplayPort-to-DVI etc. cables are available. You must buy right one.
Be aware that "Auto" button is inactive in digital mode of monitor.
I'm guessing you are using a the VGA input of this monitor (the smaller "D" shaped connector with 15 pins) on the back. If not, and you are using the DVI input (larger white connector), then check your PC video output. I've seen this occur with HP monitors when they accidentally get set to "digital" input. Its easy to set that way (even by mistake), but not as easy to reset to analog (VGA). To do that, you'll need to find someone with a DVI output on their video card. Once you connect to a DVI source, the monitir will come on and stay on. You then need to go into the menues of the monitor, find the setting and change it back to "analog". After you do of course, you won't get an image on your monitor until you reconnect to an "analog" (VGA) source.
To clarify, you know that analog is referring to the VGA 15 pin video input, and digital is referring to the DVI video input, right? You can't have the digital video unless you use the DVI input, which requires a DVI output from your computer (and a DVI cord of course).
If you already knew this and you mean that it won't switch over to your DVI, then there could be several problems. Most of them being with your DVI signal source (computer). Try booting the PC with ONLY the DVI cord attached between the PC and the monitor. If you have a VGA cord plugged into either, UNPLUG IT FROM BOTH ENDS.
The right side top button is Menu is has a letter M on it. From the menu display select the seventh option using the up and down buttons. Select the「Input Setting」option to change between the analog (D-Sub) or Digital (DVI) source. Enter the option and select Analog or Digital.
I have the same monitor and assume you have both analog and digital inputs. In other words, both a DVI and standard analog monitor input. I noticed on mine that there was a "factory reset" on the menu. Have you tried that? What type of video card are you connecting to? DVI? Do you have any adapters or gender changers connected to it?
You have to make sure the DVI output of your computer supports analog video.
Check online for a DVI pinout. You will see the group of 4 or so pins to one side of the connector provide analog VGA. If your Video card (or cable) doesn't utilize those pins, then your monitor isn't going to be supplied the signal it needs.
I guessing that since **-one responded you've given up and returned the whole mess but what the hey.
A lot depends on the KVM you're using. There are some high end units that will match different sources to the monitor but most work best with matched input and output. Unless you's specifically states that it will convert analog to digital it won't. So if it's an analog KVM then both the computer video boards need to have an analog VGA jack and the monitor does too. If the KVM is ditital you need to have all the systems and monitor digital. Savi? The Monitor may support boath analog and digital input but NOT at the same time. You can't plug in two computers at the same time, that's what the KVM is for.
The bottom line here is that you typically need to run the least common de**minator to use a KVM. Also, if the computers have different frequency (resolution) out put and you hit the KVM switch then the monitor will freak out. Some monitors will auto-switch between frequencies but most don't (especially the cheapies).
There are adapters that will down convert digital to analog. If you're dead set on using the KVM with that old Dell then you may need to plug the down converter into the Acer Video Board but you'll loose the high resolution and sharp picture from the digital video. If it was me and I had to use the KVM, I'd get a cheap digital video card for the Dell or just run two monitors.
I run 5 systems on my desk, Three of which are older servers with analog video. They share an analog KVM with video and keyboard on the wall. The other two systems are current generation and share a KVM and 27" flat panel center desk. I also have a laptop that hangs on the other wall with a laser blue tooth keyboard on the other side of my desk. Now if my wife would only let me turn part of her craft studio into a server room.....
