Just got an HP Victus TG02 desktop with error message Input signal not found

[cedangeles]

I just got this desktop and monitor in November 2024.  When I shut down my computer, I get this message "Input signal not found, HDMI, check the video cable and video source".  I've rechecked the connections and I couldn't find anything wrong.  It is on HDMI and not VGA.  My monitor (HP 524sa) looks fine except it went dark for a second tonight but got back up.  Attached is a photo of the back of my computer.  Back of HP Victus TG02

Hi @cedangeles,

Welcome to HP Support Community.

Thank you for posting your query, I will be glad to help you.

It sounds like you're encountering a common issue where the monitor doesn't detect the input signal properly, even though everything seems connected correctly. Here are a few steps to troubleshoot further.

Check Power Settings:

• Sometimes the monitor doesn't wake up from sleep or standby mode properly, which can cause the "Input signal not found" message. Make sure your desktop's power settings aren't turning off the video output or putting the PC in a state where the monitor struggles to detect the signal.

Test Another HDMI Cable:

• Even though the cable appears to be fine, sometimes a faulty or damaged HDMI cable can cause this issue. Try swapping out the cable to see if that resolves it.

Try a Different HDMI Port:

• If your monitor has multiple HDMI ports, or if your Victus PC has multiple HDMI outputs (or even DisplayPort), try switching to another port to see if the issue persists.

Graphics Drivers Update:

• Ensure that your GPU drivers are up to date, as outdated drivers can sometimes cause display issues like this. You can check through Device Manager or use HP's support page to download the latest drivers.

Monitor Settings:

• Double-check the input source settings on the monitor itself to ensure it is set to HDMI. Sometimes it may switch to another input if you’ve connected something else to the monitor previously.

PC Restart:

• Try restarting the PC to see if the monitor reconnects automatically. Some monitors fail to detect the signal after a shutdown but will reconnect upon reboot.

BIOS/UEFI Settings:

• There could be a setting in the BIOS/UEFI related to video output (e.g., integrated vs. discrete GPU). If you're using a dedicated GPU, make sure the BIOS is set to prioritize that GPU for display output.

Test Another Monitor:

• If possible, test with another monitor to see if the issue persists. This can help identify if it's the monitor or the desktop that’s causing the problem.

I hope this helps.

Take care and have a good day.

Hello,

Sorry for the delay in my response.  I reached out to HP customer service because both my monitor and desktop are still on warranty.  The agent took control of my computer and updated the graphic drivers, etc. and concluded that the reason I get the message after I’ve shut down my computer is the monitor is looking for the video.  In other words, the computer and monitor are not in sync.  I notice that when I turn on my computer, the monitor is not turned on at the same time.  There is a tiny bit of a gap. 
I don’t have another HDMI cable and I have only one HDMI port.  The input source setting on my monitor is set to HDMI.  So, what else can I do?

Hi @cedangeles,

Thank you for your response, 

It sounds like you’re dealing with a delay in the synchronization between your desktop and monitor. Since you've already gone through some of the basic troubleshooting steps, let's dive into some more advanced solutions that might resolve the issue.

Disable Fast Startup (Windows):

Sometimes, Windows' fast startup can cause issues with how peripherals like monitors are initialized. Disabling this feature can help with the detection issue.

• Go to Control Panel > Power Options > Choose what the power buttons do.
• Click on Change settings that are currently unavailable.
• Scroll down to Shutdown settings and uncheck Turn on fast startup (recommended).
• Save the changes and restart your PC.

Check Refresh Rate Settings:

If the refresh rate on the desktop is set too high, the monitor may have trouble syncing. You can check and adjust this.

• Right-click on the desktop and select Display Settings.
• Scroll down to Advanced Display Settings and check the Refresh Rate.
• Try setting it to a lower rate (e.g., 60Hz), and see if that helps.

Enable/Disable CSM (Compatibility Support Module) in BIOS:

This setting can affect how hardware devices (like displays) are detected during boot. Sometimes enabling or disabling it helps resolve such issues.

• Restart your PC and enter the BIOS/UEFI by pressing the appropriate key (often F2, ESC, or DEL).
• Look for a setting related to CSM or Boot Mode.
• If it's enabled, try disabling it, or vice versa.
• Save changes and restart.

Check Graphics Card Power Settings:

If you're using a dedicated graphics card (GPU), ensure that it is receiving sufficient power and is properly seated in its slot. Also, verify that your system isn't defaulting to integrated graphics (if available), which could cause the monitor to miss the signal from the discrete GPU.

• Open Device Manager, expand the Display Adapters section, and ensure that your dedicated GPU is listed.
• If you see multiple GPUs listed, make sure the right one is selected for display output in BIOS.

Force GPU to Reinitialize:

Try forcing your GPU to reinitialize to address any possible issues.

• Power off your system.
• Unplug the monitor and the power cable of your PC.
• Hold the power button of your PC for 30 seconds to discharge any residual power.
• Plug everything back in and power up your system again.

Try Safe Mode or Clean Boot:

Booting in Safe Mode can help eliminate any software-related interference. A Clean Boot can help disable unnecessary startup processes that might be causing the issue.

• Safe Mode: Restart the PC and repeatedly press F8 (or Shift + F8) to enter Safe Mode. Check if the display syncs properly.
• Clean Boot: Open System Configuration (msconfig), go to the Services tab, check Hide all Microsoft services, then click Disable All. Restart your PC and see if the problem persists.

Update/Reset GPU Firmware:

Some GPUs (especially high-end models) have firmware that may need to be updated to address bugs or improve compatibility.

• Check if your GPU has a firmware update available on the manufacturer's website or through HP's support page.
• If your GPU has its own software (like NVIDIA Control Panel or AMD Radeon Settings), check for any settings that might be causing display sync issues and reset them to default.

Check for Monitor Firmware Updates:

Some monitors have firmware updates that improve compatibility with various systems. Visit our HP website to check if a firmware update is available.

I hope this helps.

Take care and have a good day.
