Intel Pentium IGP, PC freezes after powering HDMI display off then back on.

Here are the specs:

MB: Gigabyte H81.Amp-Up
CPU: Pentium G3220 @ 3.0 gHz
4GB ddr3
HDD :Old WD
PSU: Corsair 430W

The computer works fine with the integrated video except for one thing...the problem occurs when I shut off the display, which is a 720p HDTV connected by HDMI to the PC's HDMI port. When I turn the TV back on, I don't get a video signal from the PC. To get video back, I've tried keying in a restart, but I was forced to hold the power button in for a few seconds and then power it on. I've updated the driver for the Intel IGP (didn't fix it) and I've installed a HD 6950.

Installing this discrete GPU fixed the issue, but the setup is not ideal. I took the GPU out of a gaming machine and am using the IGP on the gamer now. Also, the Corsair PSU does not have 2 pci-e power connectors (the 6950 has 2 ports.), so I took the PSU out of the gamer, too. That one has the required power for the 6950.

So, I'm wondering if you guys can give me some pointers to get the IGP working properly. Some links to GPU's equal or a bit better than the Intel IGP could be helpful as well.

Thank you so much and may the Father bless you.

I have the same problem with my Pentium G620's iGPU (used as an HTPC.) I went to a HD6450 so I've detoured around that... but just so you know, you aren't alone with that problem.
 
I'll check the price on that one. I really don't want to spend much more on this thing. Wifey gave me the go-ahead for $30-40 more and it looks like that one would fit the bill. You get good performance out of it? Thanks for the kind reply.

I wonder if the I3's iGPU would be any better or even if I had gone with AMD for this build. AMD probably has no problems at all with their APU's since they have a video card division.

It's at best an equal of the HD4000 Intel graphics... but the price was right: $20 AR, and it is passively cooled. I should disable it and compare it to the G620's iGPU and see if I can tell a difference...

No... the Intel chip is solid. See what mfenn suggests, I'm sure someone can come up with something...
 
1) Another symptom is that something disconnects and sometimes reconnects when I turn the TV back on. I know this because the sound is heard that Windows makes when something is unplugged and plugged back in.

2) Sometimes it gives me the warning about how the display driver has stopped responding and has recovered.

3) Sometimes it blue screens/restarts.

4) Disconnecting and reconnecting Hdmi cable does nothing.

It's definitely a driver issue because I can turn the TV off and on and everything works fine IF the Intel driver is not installed. If Microsoft made a driver for Windows that allowed me to select the correct resolution, I would use that.

I've discovered that if the hd6950 is installed, the IGP works and I can power off and power on the TV without problem.

My workaround is this: to purchase and install a cheap, CHEAP pci-e video card and continue using the onboard graphics.
 
Funny you said that because that's the one I ordered! I saved so much and I want to get this thing done, so I went ahead and upgraded shipping, too.
 
Stories like this make me cringe. Is it any wonder people are running from PCs in droves and using smartphones instead. Smartphones may not be perfect but jeez at least they ALL go into and out of standby without things like this happening. And the truly sad part is that no one really even expect to find a software solution for this intel IGP problem. As others have said the best thing to do is obtain a cheap discrete card and use that.
 
I searched and searched for a different driver to use. Nothing. I even considered reinstalling windows (briefly).

The issue is not that it won't wake out of standby, it's that the driver quits responding and I get no video. Could it be that it has something to do with Hdmi? I would try DVI, but this cheap-ish board (~$75) only has Hdmi out.

It is a bit shocking that I have to have a dummy card in the machine in order for the video to work. BTW, with the pci-e card installed, I still get the disconnect-reconnect sound from windows when I turn the TV back on. To my recollection, I've never unplugged or plugged in a monitor or turned it off/on and had it make a windows sound. But, whatever works.:\

*scratches head*

So what you are doing is... installing the GPU that sets idle, and continue to use the HDMI out on the mobo? :hmm: And that fixes it?
 
Weird, huh? It seems to work with the 6950 so far. Just to verify that the problem was gone, I sat and turned the TV off and on a bunch of times.
 
I've had that happen from time to time with other systems in the house, I always thought it was a weird C state sleep that wasn't working properly because either the PSU wasn't technically capable of power draw that low and sustained or the board not fully supporting the C state that Windows was trying to enter and when it tries to turn back on not everything is up and running correctly. But hey if you fixed your problem and haven't been able to reproduce it, just hope it doesn't come back and carry on.

FWIW I've had many problems with HDMI, TV's and PC's. For some reason TV's that double as PC screens do neither perfectly. If the TV has DVI I'll use it. Too bad your board didn't have it.....but with the new video card it will.
 
Maybe there are some optional updates that will updated the integrated graphics. I like to install all the optional updates for Windows.

There are some video and audio bugs in Win 8.1 if that is what you are using. So did you set the resolution In Windows Display settings on the monitor(TV) to 720p at ??HRZ like the TV uses?

This could just be a faulty MB or you are overclocking and broke it.

How about 3DMark? I like Mark 11 over 12, but that's me.



I'll have to try that, too.... 🙂

3dmark is cool but takes much longer to run. It also has physics test that is CPU specific. Unigine Valley is quick and doesn't really test CPU so the results are more GPU specific and clearer as to which GPU is superior.

Jeepers... Valley is brutal... 😱 It just kicked my 560ti OC in the crotch...
 
I think I'll throw 3dmark '01 on it and see what it pulls. I ran 3dmark '06 and it was painfully slow. Seems like the newer versions are for better hardware.

I might have to try Valley to save some time.
 
Isn't this a known issue with low-end haswell IGPs?

I remember this being explicitly mentioned in one of Anand's HTPC articles right around when Haswell was released. Specifically, the IGP craps out in this way with the intel driver *unless* there's another card in the system, even if that card is not being utilized. I think it was kind of glossed over because the higher end haswell chipsets don't suffer from this issue and the lower-end processors are usually paired with a dedicated GPU for HTPC use anyway.
 
I just built a HTPC and used the 4th Generation i3 4330 3.5 ghz with the 4600 graphics. It is running great. I am using it with a 40" Samsung HDTV.

I have read that it is harder to encode decode 720p than 1080p.

There might be something to be said for using better and newer chipsets. I am using a Gigabyte GA-Z87N-WIFI motherboard. I really like it so far.

I also saw some updates for HD3000 graphics on my 2600k processor. Maybe Microsoft upgraded the graphics and it didn't work right.
