If you are referring to the "monitor" output , this is a Pre-amp output which connects to a power amp or speakers that have built-in power amps. The Monitor output is a high impedance output. This output will not drive speakers directly.
when the computer enter the sleep mode, it is possible that the computer remove the check mark from this output activation.
When you have multiple ouptut like a internal LCD and output on a monitor, when going into sleep then waked up, laptop reactivate the internal LCD without reactivated the secondary monitor.
you could need to go in desktop property and reactivate the secondary monitor with the check mark listed : Activate.
If you only have one monitor but still a dual output card or two separate video card same thing can happend. try to connect the monitor on the second VGA or HDMI output and see if the video goes there.
then reactivate your secondary output and make it principal.
Does also happend when your computer is connected to a UPS power and your monitor is directly on the sector. (laptop issu also)
if a brief power outage arrive then the monitor shut down (no power) and the computer continu, as there is no monitor on the output any more Windows will automatically deactivate this monitor. when power goes back, this output is no longuer providing video. I suggest putting the monitor on a UPS as well.
Ok, so the idea of this KVM is to allow two computers which are dual monitor enabled to share one set of dual monitors. This means that PC1 can output to two monitors at once and PC2 can output to two monitors at once, however you only have two monitors. You should take two cables and plug in both to the dual display output on PC1 (if supported) and then plug them into 'A/B' Computer 1, you should then take two cables and plug them into the dual display output on PC2 (if supported) and plug them into 'A/B' Computer 2. Now take two cables and plug one into Monitor A and connect this to one of your screens and plug one into Monitor B and plug this into your other screen.
how is the monitor connected to the computer? what connection type is the monitor is it VGA or HDMI . What format is the computer video output is it VGA or HDMI. Also you may have two video outputs on the computer. Sometimes the motherboard vga output is disabled so that a much better video plug in card can be used which has its own video output port.
Starting from the monitor and going to the video connection to your computer, make sure everything is connected and undamaged. If your video card has more than one output, try switching the cable to the other output. If neither is working, and the monitor works fine from a different computer, then its the video card, otherwise its the monitor. But again, before dropping any money on a new monitor, try a different cable, and try switching the cable to the second output if there is one. A video card is definitely cheaper than a monitor.
Will the monitor work on another computer? Will the computer work with a different monitor? Are you connecting the vga port to vga output on the video card or the dvi input to the dvi output on the card. You may need a video card with hdmi output.
Some cards can send 2 outputs that is split by the cable, which is connected to 2 monitors. Generally speaking though, most just split the image up
If you're not sure if your output supports multiple monitors off one output, it's almost certain it doesn't. There is USB 2.0 to DVI, HDMI and VGA Multi-Display Adapter resolutions of up to 1600 x 1200 Allows for effortless multitasking
Connect one monitor to the second DVI-output port.
Connect one monitor to the S-video output port.
Right-mouse-click anywhere on your desktop "wallpaper".
Click Properties.
Click Desktop.
You should see 3 icons -- one for each display.
Drag-and-drop the icons so that their position
matches the physical layout of your 3 monitors.
Is that a port for an additional monitor or is it simply an alternative method of connecting the monitor to the PC. My monitor has a vga input along with a dvi input and a hdmi input. These are all inputs not outputs.. Unless the port is specifically labeled as an additional monitor output, the chances are its an input..
You may have to use proprietry software to make any additional outputs available.. if the monitor is a Samsung, go to the samsung website and search for the monitor model. or read the manual..
Depending on how much it has broke away, you may be able to resolder it back on, or find someone who can. Other than that it will be a new board, I suspect.
It seems at least a few connections are OK, so probably worth a try, before scrapping it.
