I bought a H55N-USB3 and lost my on-board HDMI video completely, not even at BIOS.
I removed my 5670 video card to use on another computer and connected my HDMI cable to the bulti-in HDMI port and now I get no video
I tried reinstalling the video card and setting on-board video manually in the BIOS with no luck.
I tried clearing cmos with no luck.
not sure what else to try?
-
Have you tried the obvious thing, the cable?
-
yes, the cable is fine. I had it working with the 5670. I edited my post so it reads better. was kind of confusing. Let me know if it need more clearing up.
-
Yes it was a little confusing but the doctor said as long as I keep taking the tablets I should be alright soon.
Have you removed the drivers for the GPU card completely now and relaoded the onboard drivers?
-
What CPU do you have in this board and did you overclock it?
-
I have an i5 655k and yes I did overclock it with my 5670. But it was reset to defaults long ago.
I even removed the battery and clear cmos and still no luck.
I see people having this issue all the time. but now that I have it, I can't find anything as search gives me an overwhelming amount of info, and always nothing close to what I want. :(
Google does not like me.

OK, i just plugged in my VGA cable and all is fine. It seems something is whack with the HDMI port.
Can I set a HDMI port preference in BIOS? maybe it's disabled by default?
-
Try reflashing the BIOS using Qflash, and be sure you Disable "Keep DMI Data" before the flash.
Then reboot to BIOS and load optimized defaults and shut down the system. Then remove your graphics card and start the system up using HDMI connected, it should then start using the onboard graphics.
If HDMI fails, try VGA again just to be sure it's still working. Also, be sure you are changing your monitor to HDMI, just a reminder ;D

Can you try the DVI port? You can not test it with a DVI to VGA adapter.

I noticed my cmos wasn't reset properly. My date/time was reset, but all my other settings were normally adjusted. I loaded optimized defaults, and now all settings are properly set, but still no HDMI, although HDMI works with VGA as dual displays. HDMI is primary, but is a blank screen at all times. Then auto-switches to VGA after a timeout.
I will try reflashing the BIOS. I do recall flashing a beta BIOS now that I think about it. F6A it looks like.
will report back on results

bummer, I flashed F5 BIOS from gigabyte's site, and still nothing from HDMI. I even manually switch monitor from VGA to HDMI when in windows, and it's a blank screen and switches back to VGA on it's own after a timeout.
any other suggestions?
I know HDMI ports works as I had it working when I first set it up. but I don't know of any setting to enable HDMI.
-
Are you able to try the DVI port? No adapter.
-
OK, I found my DVI cable and still no video.
did something break? It seems weird it was working fine, and adding a video card broke it.
-
What are you trying to output the display to?
-
Do you mean what monitor am I using?
My monitor is a Hanns-G HH221
I get nothing at all, not even startup Gigabyte screen, no windows, not even after windows loads drivers.
-
This monitor supports all three types of input? ie VGA, HDMI and DVI.
Does it auto switch or do you have to select the input?
-
From what I can tell the Integrated Graphics in the CPU is fine but a link going from it to the HDMI & DVI ports is broken...so I think you have to send the board off for a replacement.
You have ruled out all other possibility’s that I can think of.
-

Not sure where this came from? So you remove your video card and the HDMI & DVI ports start working!
-
No the OPs already tried that and no joy Peter. I am wondering about whether the output is ok just not being selected on the monitor but sometimes it is hard to keep people focussed ;)

No, originally the HDMI was working fine. I added a 5670 for gaming. I removed my 5670 so my buddy could borrow it. Now built-in HDMI/DVI has stopped working.
@Dark Mantis
My monitor support only VGA/HDMI, but has a DVI/HDMI converter cable I think. It auto choses the cable type and lets me m anually switch as well. It seems to try HDMI first, then it switches to VGA because there is no signal from the HDMI.
I took the DVI/DVI cable to my gaming monitor (Samsung T260HD) and no display there either.
any other ideas?

ps. Thank you very much guys for your help. I want you to know your help is greatly appreciated.

Have you tried resetting the CMOS?
-
I tried and it didn't seem to take. I even removed the battery and shorted it out on the motherboard to help drain any remaining power. On reboot I noticed my memory was running full speed and checked the BIOS and it was still manually overclocked. But the date/time was reset to 01/01/10 00:00:00
Maybe I'll try a longer clear cmos. My old DFI motherboard wouldn't clear unless it sat for 10 minutes minimum.
I'll get back to you in a bit. I'll wait at least a half hour. I better change some setting so I know it cleared properly.
-
Well, it still didn't clear the cmos settings completely. It reset the clock, and amazingly reset the driver to extended mode instead of cloned mode. Don't know how that's even possible, but I got a blank windows logo on boot this time. strange.
well, is there another clear cmos jumper? I think this one clears only the clock. All my OC settings were untouched still.
I don't see any other listed in the manual. maybe one is hidden somewhere?
-
What I would suggest is to first unplug the PSU to motherboard connection both of them. Also make sure that the PSU is unplugged from the mains. Next remove the battery and then short the jumper to CLRTC or CLCMOS and leave it for 30 mins. Make sure you have removed any USB conectors also.
-
I already did all that. lol
I only find one jumper. CLR_CMOS, but it only clears the clock?
I tried also loading fail safe defaults and same results.
I left jumper on and psu unplugged for a little over a half an hour with no luck.
I will try one more time before bed and leave jumper on and psu unplugged overnight. If that doesn't do it, I don't know what will.
-
When you have done it and return to the BIOS to load the optimised settings do not keep the DMI settings when asked.
-
I've never noticed keeping DMI settings in BIOS. I get the option when flashing a new BIOS.
Where exactly would this option appear, so I can know to look for it.
-
No it will only appear when you are flashing the BIOS. I was just thinking that we were flashing it at the same time.
-
OK, I got a new menu as I forgot to unplug the VGA to see if HDMI would work. I got a cmos checksum error menu and it listed 4 options. defaults, last known good, profile 1, profile 2. number 2 was the default option, the last known good which is why it was not seemeing to clear the BIOS as it was loading it back in. or maybe the clear DMI during flash was doing this before?
Anyway, I think I'm just going to RMA this board. It should have worked by now. I'll call newegg and see if they'll let me cross ship a new one.
Thanks again for all you guys' help.

OK, I got my new board yesterday and now I still have no HDMI or DVI, but VGA works fine. Could it be the CPU? I thought the motherboard controlled the vga/dvi/hdmi stuff? maybe not.

No the graphics are controlled by the CPU. You have to have a CPU with integrated graphics to enable the onboard graphics to work.
-
Yes, I understand the CPU has to have a graphics chip on it, and it does. I have the i5 655K.
The problem is, the video only works on the VGA, but not on the DVI or HDMI. Is this part on the video or on the motherboard as the ports are on the motherboard. Logic would seem to be if VGA works, then the CPU is good as the graphics work, and the MB has issues with the DVI and HDMI ports. But maybe not?
-
Yes, I would tend to agree with you on that point. Even though there are differences if the CPU is outputting video then I think it is more likely that the motherboard or at least the drivers are the problem.
-
I'll be! It is my stupid 1080p monitor. It is going to sleep and the Intel HD video isn't waking it up. I forgot to turn on the monitor before starting the computer and when I did, the video was working. On reboot it worked. but on cold boot it would not work.
I guess the restart is fast enough to not let the monitor sleep. But power on is too slow and monitor goes to sleep but the Intel video isn't sending a wake signal properly or something.
whew, and I was getting ready to call Intel for an rma. lol boy do I feel foolish.
Thanks for all your help.

ps. there isn't by chance a bios setting for this hdmi wake up?
