    I have an Compaq Presario sr2011wm PC Desktop.

The monitor is telling you that it does not see the computer. First, remove the monitor cable from the back of the computer, check for bent pins on the connector and replug in the connector.
If that doesn't work, try swapping to a different monitor to see if it sees the system. If this works, you have a bad monitor or monitor cable.
If that doesn't work, open up the computer remove the video card, clean any dust from around the card and socket and replug the video card.
If these ideas don't work,get back to me and we'll go from there.
Have a good day!

No signal when i used vga monitor connector to pc, no problem in dvi


Michael,
I have both ASUS and LG monitors with multiple input choices. On both, when the monitor is turned on, it remembers the last input source. Both monitors (and presumably yours, as well) have an INPUT selection in their SETUP MENU.
So, I'm suggesting you search your monitor for an INPUT selection option, then choose "VGA" rather than DVI / HDMI / AV / COMPONENT / CABLE / ANTENNA, etc.
Hope this helps.

How do I fix the error no vga input signal no dvi input signal monitor going to sleep


Check if you VGA is properly settled in the PCI slot. Try to take it out, clean the slot for dust.
If that doesn't help, it is well possible that you VGA is not working any more.

No signal detection on all the input ports from the PCDell lcd display 27


Well if you have a VGA monitor it definitely wouldn't go into any port but the VGA port.

Have you looked into the Bios or System Setup to make sure nothing in there regarding the VGA port is off?

I think your problem is either the Monitor is bad or the Video Card in the computer is bad. Make sure the vga cable is pushed in good in the computers vga port and that it is in good in the back of the monitor. Also you can look at the end that goes into the computer and see if any of the pin or prongs are bent. If so, that could be the problem. Don't get alarmed if it looks like some of the pins or prongs are missing, that's just the way it is made.

Does your monitor give you a message on the screen that says "No Input Signal"? If so that's a sure sign that maybe the Video Card in the computer is bad or is not pushed in all the way inside the computer if it resides in one of the slots. Try another monitor on the computer and if it gets the No Input Signal message then the video card is definitely bad.

To see if the Monitor is the problem just try it on another computer. If it fails on another computer, then you know the monitor is bad.

No input signal


Make sure the connects of the vga cable is in the computer good and into the monitor good. If you still have a problem look inside at the pins or prongs on the end that plugs into the computer. Make sure none of them are bent. It will look like some are missing, but that is normal.

If they are not bent and you have both ends of the cable secured tightly, then your VGA Video Card might be bad. You can try the monitor on another computer and if it comes up ok then for sure the video card is bad on the original computer. If you get a no input signal when you put the monitor on another computer then it's possible the monitor is bad, in that case try another monitor on your original computer.

I have a HP m7570n. How do I use a flat screen tv as a monitor


This depends on the TV's available inputs. The Pavilion m7570n has only a VGA output in the standard configuration.

Thus if the TV has a VGA port, turn off the computer and the TV. Then connect a standard VGA (RGB or D-sub 15-pin) m/m cable between the computer and the TV. To use the TV speakers, connect a 3.5 mm audio patch cable between the computers Line-out (green speaker port) to the VGA audio in. Turn on the TV and set the input to VGA (with the Source or Input button on the remote or the TV). Then turn on the computer. Windows XP should find the correct resolution to work with the TV. (If you turn on the TV after turning on the computer, you may get an unsupported signal. Press Ctrl-Alt-Del twice to restart the computer.) If it doesn't work, you may need to connect a different monitor and set the computer to a low resolution before connecting the TV and the computer.

If the TV only has composite or component video inputs, you will need a VGA to video converter (http://www.svideo.com/pctocomponent.html for example). A VGA to component cable will not work; those are for projectors that read an RGB input. TVs interpret YPbPr.

If you have added a video graphics card, you may have an HDMI and/or DVI port(s) on the card. In that case, check the specs of the TV. Some TVs will support HDMI or DVI-HDMI inputs from a computer. Others will not (since computer video signals are not the same as the signal from a set-top box). If you use a DVI-HDMI connector, make sure to use the HDMI port labeled for DVI and connect the audio cable as with the VGA connection. If you use an HDMI connection, you may need to set the sound properties to that of the HDMI port. (Find the control panel item for sound (under Hardware) and then select Manage Audio Devices. Set the Playback properties. If it doesn't work, use an audio patch cable.) Some TVs have RCA audio inputs for the HDMI-DVI connector. In that case, you will need a female 3.5 mm to RCA M/M adapter (if you use a 3.5 mm patch cable). There is a similar device if you want to use an RCA audio cable. You may need to enable the video ports on the graphics card before swapping monitors.

Some video cards have a TV out. In that case, connect the appropriate connector (should come with the video card). Then connect to the component, composite or S-video input on the TV.

Again turn off the TV and the computer before making any connections.

You will probably need to provide your own cables for must of these connection options.

I hope this helps.

My dell inspiron 530 shows a block with red, white, green, and read, can't get to the my programs????


That "red white green and blue" block is a color pattern tester. that means the monitor is on, but is not receiving a signal, so its running tests. If your monitor has Digital input and VGA input, you may just need to switch inputs. Look for 1 or VGA if youre using the blue hook up. look for 2 or digital or dvi if youre using the larger white hook up. Some monitors also have 'auto detect'. If you are in "auto detect' bbut the color box is still there, then your monitor is not receiving video signal from the computer. It could indicate a bad cable or no signal being sent by the machine. If you try another monitor, you can see if the machine is working. I would try a monitor setting for VGA-1 first, since thats most common.

Cpu says no input vga signal, then goes to sleep


The no input VGA signal just means that the monitor is not receiving anything from the graphic card on the tower. Is the card a digital (DVI) output card? You'll know by the connector, it's white and slightly wider than a standard VGA connector. If so, perhaps the monitor is set to the wrong input?

If that isn't the case, and the computer is using an on-board or built-in graphics controller, you could try resetting the system's CMOS settings by setting the clear-settings jumper on the system board, or simply remove the plug and CMOS battery for a few minutes. Check the computer's documentation on the exact steps to do this.

Hope this helps!
