Solved MSI GTX660 HDMI outout.

[AddRAM]

When I use the hdmi output of my gtx660, after the screen goes to sleep and I try to revive it, it keeps telling me to check the signal cabel, I`ve set hdmi to default but it still won`t come up unless I change it manually, any ideas. The hdmi cable is hooked up to my main HP2311x monitor.

Can't seem to find a fix other than a reboot. Do you have a dvi cable you could use. HDMI does that with tv's a lot, normally not on monitors though.

I think I got it, just played with the nvidia control panel a bit, now to see if the monitor comes back to life after waking back up. A DVI cable works pefectly, bit I want that 2nd dvi port to go to my hdtv with my Monster DVI to HDMI cable. I then have 3 monitors running off the 660.

Nope, can`t make it work, the hdmi connection keeps getting broken and won`t comeback up after sleep, looks like this card is goin back.

As a last resort I will try using my Sony HDMI cable and see if it behaves properly.

Do you have pll overvoltage enabled in your bios? That might cause that, i read that somewhere, Toms Hardware maybe.

OK, I`ll bite, what would that have to do with this ?:huh:

 

[Dude]

Like I said I read it on toms hardware, I will dig through my history. Found it, it was on a Asus board but thought it might help you.

That article talks about not waking from sleep mode properly, ( Although that`s not how he words it ) my pc comes out of sleep fine ( always did ) just when I hook the HP2311x to the GTX660 with a hdmi cable it won`t wake the monitor back up. The other monitors connected via DVI and DVI to HDMI come up fine.

Okay, maybe someone else will come in with help. Try posting on the MSI site too. And once you get it working you need to Add a fourth monitor

I don`t own a display port cable or a monitor with a display port input. Nor will I ever

 

[Dude]

I have a display port to dvi and display port to vga adapter, but no more monitors

I guess I`ll have to hook up 1 of my 9600 Gt`s to have 3 monitors, this sux !!

I`ll call MSI and see what`s up with this.

Well I kept battling with it, I used my Sony HDMI 1.4 cable and it seemed to do the trick. The main monitor wakes up fine from sleep now and all 3 monitors are functioning as they should

Good to hear you got it going!!
