Inspiron 5675, No HDMI out signal to monitor

Computer's on, and there's no HDMI signal from the computer to the monitor. I know for a fact it's not the cable. I've tried it on other computers and it works fine. At times when I turn on my computer the HDMI video signal to the monitor either goes through or it doesn't. Why I don't know. I do know that if I put the computer to sleep and then reactivate this happens. I know the computer's reactivated because I can hear the fan going back on and the monitor going from nothing on it to "scanning" and then after a few seconds it says no signal. Only after turning it off and on several times did the video start working. 

Edit: I just finished work. I restarted the computer it worked. Then I put it into sleep mode, and the same thing happened. When I pressed a button to reactivate the computer the fan went on but nothing on the monitor for several minutes. I turned off the computer and on again and same problem, no video, but when I turned off the power strip, then turned on the computer it worked okay.  

Any ideas? I use my computer at work and don't want to go through a situation like I did today where I had to keep turning it off and on for about 50 minutes waiting for it to work.

Re: Inspiron 5675 No HDMI signal to monitor

Are you using onboard video or an add-in video card? Do you have the latest AMD chipset and video drivers installed?

Open the Windows Power options screen and select the currently active Power plan. Then look for the link to Additional Options. On that screen disable Hibernation, Hybrid Sleep, and PCI Express Link State Power Management. Save the changes to the plan and reboot.

See if that helps...

Thanks Ron.

The video card is the one that came with the thing.  I didn't change it.

Did everything you mentioned above.  It did help one thing.  If I restart the computer monitor kicks back on no problem, but if I put it in sleep mode, then press a button to awaken the computer it still wont' give any video signal.  Still wondering **bleep** but at the same time at least the computer is up and running and I can work throughout the day with no problem.

That doesn't answer the question. Are you using onboard AMD video or some add-in (NVidia) card? Go to the Support page and put in your Service Tag. Follow the links to find your Original Configuration and see what "video" items are listed.

Then make sure you have the latest chipset driver and video driver(s) specific for your system and version of Windows.

What button are you pressing, keyboard, mouse...? 

Reboot and immediately press F2 to open BIOS setup. Look for "USB Wake Support" (or similarly worded option). Make sure that option is enabled. Note: the online service manual doesn't list BIOS setting options for this model so you may not have this option in BIOS setup. If you have it and enable it, be sure to save the change before exiting setup, but do not change any other BIOS settings.

Either way, after rebooting, open Device Manager and expand list under USB. Double-click a USB root hub and click its Power Management tab. Uncheck the box "Allow PC to turn off...". Repeat for all USB root hubs.

Now, expand list under Human Interface Devices (HID) in Device Manager. Double-click each HID entry and look for a Power Management tab. If it has one, uncheck that same box "Allow PC to turn off...". Reboot when done and see if that helps.

Not sure what word got bleeped, so use a different/acceptable word if you want to elaborate on that more.

Re: Inspiron 5675 No HDMI signal to monitor

I'm using the onboard AMD card.

As you recommended I updated the drivers before I gave the reply.  

Again thanks for the quick reply!  

I'll try the other things you mentioned.  Right now I got two little kids driving me nuts.

Re: Inspiron 5675, No HDMI out signal to monitor

That's definitely not normal. My 5675 has a Radeon RX570, and I have not had any problems with the system going to sleep and not finding the monitor. Sounds like a settings issue.

are there multiple HDMI ports on your card? Have you tried using a different one?

What's more important, two lil' kids driving you nuts or your PC driving you nuts? 

Let us know if those extra settings changes help...

Re: Inspiron 5675 No HDMI signal to monitor

Thanks for all the help.

Which button?  Keyboard or mouse.  Each time the fan goes on and the lights on the computer go back on so I know the computer is awake but again no video signal.

Tried the f2 Bios option.  No USB wake support option.  There was a USB option but it only allowed me to shut off or on the front or back USB ports.

Went to the device manager power management option and shut off all of the "Allow PC to turn off.." and still the same problem.

Did the same in the Human Interface Devices (HID) section.  Same problem too.

 

I agree it's something with the settings.  The monitor works fine, the cable is fine. I just don't know what the eff it is.

Also I didn't intentionally write anything worth bleeping so I don't know what was bleeped out.  When I say a four-letter word on a highly moderated forum I use the word "eff" or "frack."

 

In any case if I don't figure it out the computer is otherwise working fine and it's not something messing up my day to day work.  

 

 "are there multiple HDMI ports on your card? Have you tried using a different one?"

Yes but there's only one port where the video cable fits into nicely.  I tried other ones but it didn't fit into those others.
