Hdmi--->Dvi No Signal On Monitor

Here is my setup for the roxio hd gamecapture pro:

Xbox to roxio via hdmi (input)

Hdmi (output) to monitor via HDMI-->DVI cable (http://www.newegg.com/Product/Product.aspx?Item=N82E16812189057)

The USB cable is plugged into my laptop doing the recording. Roxio software picks up an image and everything seems fine. So the signal from the xbox through the roxio to the laptop seems fine, I can record without issue.

Problem: Monitor picks up no [digital] signal. So monitor is blank, no picture.

I've looked into multiple threads and these are the only two relevant ones I found:

Conclusion: Something is wrong with the roxio firmware/software

Conclusion: I have to buy some sort of passive splitter

So WTF, why won't it send a signal via regular HDMI to DVI? Am I missing something?

dvi no signal

DVI stands for Digital Visual Interface. This is the port and cable that was used before the HDMI to transfer the digital video data over the copper wires inside it to display output devices. The DVI cable was widely being used for all sorts of display applications such as monitors for PCs, TVs, Projectors, and whatnot. There are small copper pins on both ends of these adapters that connect with the PC or Input device at one end, and on the other end, they connect to the output display device.

DVI No Signal Issue

DVI offers a better picture than a VGA interface and that allows you to have the best display experience. No matter if you are going to use the DVI for gaming, video streaming, or anything like that. DVI gets you the best possible Display without causing you any troubles at all. However, there are not any sorts of disturbances like noise on these DVI cables, but you might get no signal message on the screen coupled with a black screen. That can ruin the experience for you and you should be able to fix it if a problem like that occurs. A few things that you can do if you are seeing this problem is.

1) Check the output Resolution

Most of the time, the problem is caused due to the output resolution. If you have recently changed the resolutions and stepped them up. That might be the problem that can cause you to have this error. You will need to make sure that you check on the resolution that is supported on the output display or the projector that you might be using. This is going to help you out in fixing the problem for good. You need to manage the output resolution according to the display that you are using and all that will allow you to make it work without causing you any trouble like that.

You also need to check on the cable as there are different qualities of DVI cables that you can get off the market. You need to ensure that the cable that you are using can take the resolutions and set the resolution accordingly. This will help you out in solving the problem for good.

2) Check the Refresh Rate

Another thing that you will need to be careful about with the settings is the refresh rate. You will have to ensure that you are setting the refresh rate right and correctly. This is going to ensure you that you are making it work in the right manner. To set it straight, you will have to check on the refresh rate that is supported by the output display that you are using.

After that, you will have to set the refresh rate accordingly and then save the settings. This is going to help you in solving the problem. After you have set all the settings straight, you will need to restart the display in order to solve the problem optimally for you.

3) Clean the Cable

At times, there can be some problems with the DVI cable being lose or there are multiple other reasons behind this. You will need to ensure that you are fixing it all in the perfect manner. To start with that, you will need to take the DVI cable off on both the input and output devices. After that, you will need to clean the adapters on both sides and then make sure that you are tying them up tightly on both ends.

This will optimally be helping you in solving the problem that you are having with your DVI cable showing the no signal error and after that, you can enjoy the perfect display without any problems at all.

4) Replace the Cable

At times, you might be facing this problem due to some sort of issues or errors on the cable and it might be damaged or gone bad. You can try changing the cable once and that will help you in sorting out the problem for good. Just make sure that you are getting the right cable that doesn’t have any rots of issues or problems on it and plug it in tightly. This is going to make it work perfectly for you and the error will be gone for good.

How to Fix a No-Input Signal to a Computer

By Joshua Phillips

Computer monitor flicker is caused by a bad configuration or failing hardware.

When your business doesn't have an Information Technology department, it may fall on you to keep your computers running in the event of an error. If your monitor is displaying "No Input Signal," there is no image displayed from your PC to your monitor. There are several possible causes for this error. To fix it, you must determine which component is defective, ranging from the cables that attach your monitor to your PC to the monitor itself or even your PC's video card.

Unplug the cable running from your monitor to your PC and plug it back in, making sure the connection is firm. The most common cause of this error is a loose cable.

Reattach the cable running from your monitor to your PC. If the monitor is still not displaying a signal after firmly reattaching the cable, the problem could lie with the cable, especially if the cable has visible damage.

Replace your monitor with another monitor if possible. If the "No Input Signal" error still appears, the problem does not rest with the cables or the monitor, but with your PC.

Open your PC case and locate your video card. Remove the card and then replace it firmly in its slot or, if possible, insert the video card into another slot on your motherboard. A video card that is not making a firm connection will not display images to the monitor. Close your PC case and test the monitor again.

Replace your video card completely. Your video card may suffer from internal damage that is not allowing it to output a signal.

Tips

  • If you are still not receiving a signal even after replacing your video card, you may also need to replace the computer's power supply and, in a worst-case scenario, your computer's motherboard.
  • If your computer is still under warranty, arrange for an official repair before you open up your computer. Often, opening your computer yourself will void your warranty.

Warnings

  • Always ground yourself by touching a metal object before touching any component in your PC case. Failure to properly ground yourself can result in damaged components.

How to fix "no input signal" error message

Updated: 06/30/2020 by Computer Hope

Black computer screen.

If your computer monitor is displaying the error message "No Input Signal," try the troubleshooting options in the sections below.

Computer not transmitting a signal

Make sure the computer has power. If the computer is turned off, it cannot transmit a signal and causes the "no input signal" message.

Monitor not connected properly

Verify the monitor cable is connected correctly and securely on the back of the monitor and the back of the computer. The monitor cable connects to the back of your computer using either a VGA, DVI, HDMI, or DisplayPort connector. The pictures below are examples of the VGA, DVI, HDMI, and DisplayPort connectors on a video card.

VGA connector

DVI connector

USB-C, DisplayPort, and HDMI video ports

Verify the monitor cable is not loose by disconnecting the cable from the back of the monitor and reconnect the cable. It's also a good idea to rock the cable back and forth to make sure it's not loose.

Tip

When disconnecting the cable, make sure none of the cable's pins are bent by examining the end of the cable. If any of the cable's pins are bent or broken, the cable may be defective and should be replaced.

Note

Some older monitors may have cables that cannot be disconnected from the back of the monitor.

Next, disconnect the monitor cable from the back of the computer and reconnect the cable. When connecting the cable to the computer, ensure the cable connection is tight. With a VGA or DVI style connector, like the ones shown above, screws can be tightened and hold the connector in place.

Tip

Some computers may have an onboard video and a video card. When working with this type of computer, you'll have two different connections for your monitor on the back of your computer. If you see more than one VGA, DVI, HDMI, or DisplayPort connector and the monitor is not working, try the other connector.

Incorrect input selected

Newer monitors are capable of connecting to a computer using a VGA, DVI, HDMI, or DisplayPort connector. For these types of monitors, the correct input selection needs to be used. Access the settings on the monitor using the buttons on the front or bottom edge of the monitor. Look for options to select the type of connector (e.g., VGA, DVI, HDMI, or DisplayPort), and select the cable your monitor uses.

Bad hardware

If the connections appear to be correct, either the monitor or the video card is likely bad. It's also possible that the motherboard in the computer is defective, preventing a signal from getting to the video card and monitor. To test what component is bad, either connect a different monitor to your computer or connect your monitor to a different computer. We recommend testing the motherboard for any issues, as well. See: How to test a computer motherboard and CPU for failures.

  • If another monitor works on your computer, the monitor is bad.
  • If your monitor works on another computer, your video card may be having issues. See: My video card isn't working.
Tip

If you believe your video card is bad and your computer has an onboard video, the motherboard needs to be replaced. You could also install a new video card instead of replacing the motherboard. See: How to install a computer video card.

Computer not posting

Verify your computer is getting past the POST process and that it is starting up. The "No input signal" message can sometimes appear if the POST process is failing, and the computer cannot boot properly.

If the POST process is failing and the computer is not starting up, the motherboard could be at fault. A short in the motherboard or a bad capacitor are common causes for a computer motherboard to not pass the POST process.

Monitor works for a while, then loses signal

If the monitor works for a while, then stops working and displays the "No input signal" message, the monitor or computer may be overheating. In the event of the monitor overheats, it stops working to prevent further damage. If the computer overheats, the computer may stop sending a signal to the monitor, and may also shut down to prevent further damage to the computer hardware.

Fixing a monitor that is overheating is generally not worthwhile. The cost to fix it is likely more than the cost of buying a new monitor. For that reason, we recommend replacing an overheating monitor.

If the computer is overheating, the fans that keep the processor, video card, or power supply cool may have failed. Check the fans to see if they are spinning. If they are not spinning at all when the computer is turned on, the fans need to be replaced. If the fans are spinning, use a software diagnostic tool, like HWMonitor, to determine if the fans are spinning at the correct RPM. It is possible that the fans are not spinning fast enough, indicating they are bad or full of dust and need to be cleaned or replaced.

If the overheating is related to the computer processor, you may need to replace the heat sink and fan assembly. It's possible that the CPU may be damaged and needs to be replaced, as well.

For a video card or power supply, the fans are usually integrated into the hardware and not easily replaced, if they can be replaced at all. You may need to replace the power supply or video card to fix the overheating problem.

No signal dvi

Plug it in, switch it on—it sounds easy enough to get your PC running, but it isn’t always that easy. It doesn’t matter if your PC fans are spinning if you’re seeing nothing on your monitor that allows you to actually use it. A no signal error on a monitor can leave you scratching your head without answers.

Thankfully, this kind of problem is usually easy to troubleshoot. If some of the more common fixes don’t work, then it points to a likely hardware fault that you’ll need to investigate for repair or replacement. To help you deal with display issues, here are some troubleshooting tips you can try when your PC monitor has no signal.

Check Your Cabling and Power

Before you rush to rip out your graphics card or head to Amazon to buy a new monitor, you should look carefully at your PC and monitor to ensure you have no cabling or power issues.

This is a simple check to complete. Start by tracing the cabling between your monitor and PC to ensure that you have no loose connections. A loose HDMI cable, for instance, could be preventing the output from your PC from being displayed (and vice versa).

You may also find that the display cable itself is at fault. If you see cable damage, or if the cabling is quite old, swap it out for an alternative. This can sometimes immediately resolve any issue with your monitor display.

There could also be a power issue that prevents your monitor from working correctly. If your monitor is displaying a no signal error, then you can assume your monitor has power, but if your PC isn’t on, you won’t see any error displayed.

Is The Monitor Input Source Correct?

A no signal error on a monitor could be a sign that your PC monitor is ignoring the graphics output from your PC. This can sometimes happen if the input source on your monitor is set to the wrong device.

Most display monitors have multiple input sources available, including VGA, HDMI, and DVI inputs. This allows you to connect multiple devices to the same display. This could be several PCs, or a PC and a games console, which you could then switch between using your monitor’s firmware menu or physical controls.

If this is the case, make sure that the input source on your monitor is correctly set. If it isn’t, switch to the correct source (for example, HDMI or DVI for modern PCs) to get your monitor working again.

Check Monitor Resolution

A PC monitor has a set range of display resolutions that it can use to display your PC output. If your PC’s graphics card is set to a display resolution above what your monitor is capable of displaying, you’ll likely see a blank screen or a no signal message appear.

Thankfully, fixing a blank monitor screen after changing your display settings is an easy process. If the monitor has suddenly lost resolution after changing the settings yourself, wait 15 seconds—Windows will revert back to your previous resolution after this point.

If you’ve haven’t recently changed your display settings, then your monitor resolution could have been changed automatically. There are ways to get around this, including restarting Windows and booting into Safe Mode to bypass the issue with a higher resolution.

By default, Windows will use a much lower display resolution in Safe Mode than during normal use. This will allow you to change your standard display resolution to a lower setting that your monitor can support.

If you’re unsure what resolutions are supported by your monitor, you should consult your user manual or the manufacturer website to find out. Alternatively, use the 15-second window to change your resolution for a bit of a trial-and-error. If the resolution stops your monitor from working, Windows will revert the setting to the previous setting that worked.

Update Your Graphics Card Drivers

When a display problem occurs, the monitor itself can often be the focus of your diagnostic efforts, but the graphics card your PC uses is often the bigger culprit. If you’re seeing a blank screen on a new monitor, then it’s likely that a new graphics card driver is in order.

As we’ve explained above, your PC can sometimes use a resolution outside of the range supported by your monitor. Equally, your monitor can sometimes support resolutions that your graphics card doesn’t yet support, especially if you’re moving to a 4K monitor or from a 60Hz to a 240Hz display. 

Thankfully, this is often resolved by updating the graphics card drivers (so long as the graphics card is relatively new). It’s recommended that you update your drivers on a regular basis to gain access to new features and bug fixes. This includes support for new monitors and display resolutions.

For instance, if you have an NVIDIA graphics card, you can easily update your NVIDIA drivers using Windows Update or, for the latest drivers, by downloading them from the NVIDIA website directly.

Test With An Alternative Monitor Or PC

If you’re confident that there isn’t a software issue (like outdated drivers) causing no signal to your display, then you may need to try an alternative monitor or PC as part of your troubleshooting efforts.

Replace the monitor attached to your PC with a spare (if you have one available). If the problem is replicated, this would likely indicate a problem with your PC that you’ll need to diagnose further.

Likewise, if your main monitor stops working, but a spare works fine, then this could indicate a problem with your monitor hardware. However, this does not necessarily rule out a further software issue. For instance, outdated drivers or incorrect display resolution could still cause this fault, so you’ll need to investigate further.

Replace Your Hardware

After thorough testing, if you’ve exhausted potential software fixes and any issues with your hardware can be replicated with other attached devices, then you’ll need to consider replacing your hardware.

For instance, a broken graphics card could stop any display output to your monitor, resulting in a no-input signal. If the drivers aren’t the problem, you would need to replace your graphics card.

Likewise, a broken monitor that doesn’t work with multiple devices isn’t going to fix itself. You should look at your repair options under warranty or, failing that, consider buying a new monitor.

This would also be a worthwhile decision if your monitor flickers or there’s a sign that the unit is starting to fail. This might be the case if your display takes a long time to switch on, for instance. 

Fixing PC Hardware Issues

When a monitor displays a no input signal error message, don’t panic. The steps above should help you troubleshoot the issue, but you may need to look at diagnosing your monitor or PC further to consider whether you’re due a replacement or repair under your device warranty.

Investing in the right PC hardware is essential—you don’t want to end up in the same situation a year or two into the future. Cheap isn’t always cost-effective, but make sure to consider your budget carefully before you rush to buy new PC components, or a new PC or monitor entirely.
