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

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.

My hp pavilion slimline s3020n pc is on but cannot view on the screen it says on the monitor VGA: no input signal

Check the video cable connectors, remove the video connectors and reconnect them again.
Check the monitor input settings make sure the input is set to VGA and not to DVI.
Try a different monitor.

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 ( 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.

I have a dell dimension 3000, bought a new HP 2310E monitor with 3 ports. DVI, HDMI & display port. Told to buy a cable with VGA to connect to dell and DVI to connect to HP Monitor display port....

Hi sshorne9780,

I see that you are having a check input error on the Monitor/LCD that your are connecting to your Dell tower, please see steps below.

  • On your HP 2310E make sure that your HP is set to the input/source that you are using and make sure that you only use one type of video cable for the issue.
  • I see that you mentioned that you have a VGA cable and a DVI cable, you can only use one type of cable for a video connection.
  • VGA would be the Blue tipped cable connecting to the tower and going to the LCD monitor.
  • DVI this is a black cable connecting to a white port much bigger than a VGA port and is rectangular in shape unlike the VGA
  • moz-screenshot.pngmvincentc_34.jpg
  • and on your LCD monitor check the input type to see video from the tower.
  • everything seems to be OK you just need to change the input of your LCD monitor for the video to show up on the screen.
  • also if you are using HDMI for the video u will need to change the setting of your Audio and set HDMI as the Default to have Audio come out from the HDMI connection together with video, the HDMI viedo will automatically be detected as long as the LCD monitor's input is set to HDMI.
I hope that this will able to help resolve your concern.

Thank you for choosing Fixya,

I just purchased a acer h203h and when I hooked it to my computer it says no signa and light turns red.

Please check the video input selected, press Menu botton, the monitor will show you among other information the input selected, if indicates VGA, you must have connected the corresponding cable between your PC and monitor, if it indicates DVI and your computer doesn't have DVI port press the Input botton to select VGA.

How do i connect to an hdtv ?

You're going to need to connect a cable supported by BOTH the PC and HDTV. Check your HDTV's jack panel or manual. List the types of Input jacks it offers. The HDTV will likely have Component, Composite, DVI, HDMI and maybe even VGA jacks. Do the same for your PC. It likely has one or two Video Output jacks. Typical Video Outputs are DVI and VGA. The VGA type has been standard for years. It consists of a total 15 pins in 3 rows. The DVI has a number of pins, but most noticeable is a wide tab at one end of the jack.

If your HDTV has a jack that matches one of those found on the PC, you're in luck. Purchase a cable that will connect them - this would be either a VGA cable or and DVI cable. Nearly any inexpensive VGA or DVI (Digital Video Interface) cable 6 ft or less will do, but the better cables cost a bit more and when the distance is increased, the quality (or lack thereof) really becomes visible - especially on the lager HDTV screens.

If you want the sound to go to the TV speakers or elsewhere, you'll need to get a cable with a 3.5mm stereo plug (or whichever type your PC has - but that's the most common) to RCA or whatever the audio input jack type is that is associated with the video input you chose. The audio input must be the one associated with the video input - other wise you will not hear the audio on input 4 while watching input 3. The PC audio out is analog, so do try to put the signal into a digital input.

If you don't have a matching video input jack, you'll have to purchase an adapter or new video card with jacks that match your TV. Do not buy simple adapters that change VGA to DVI as they will not convert the actual analog VGA signals to Digital Video signals expected by the HDTV's DVI jack. The best bet is to buy a modern video card supported by your computer's mother board and OS that has a fair amount of memory (512 MB is a good start). If your HDTV has HDMI jacks and you wish to play the sound from the HDTV's speakers, get a card with HDMI output and buy an HDMI cable. It will send both the sound and video to the HDTV for you.

You can read a nearly endless list of articles about HTPCs aka "Home Theater Personal Computers" for ideas and deep discussions about everything from soup to nuts to implement, design and set up on google.

I hope this helps - good luck!

DVI no input signal......VGA input active.

Are you running an additional Video card? Or are you using the built in one.
You might try cleaning the connector / plugs with acetone from finger polish remover or de=natured alcohol.
Never jam anything on a computer.
If its an add on card, remove it and reboot. Shut down and reinstall card and reboot.
keep me posted please,
