When PC goes to sleep i have to reconnect HDMI cable for Display to work

[jrosh0]

Everytime i manually set my computer to sleep or it does so itself, i have to unplug and replug in my hdmi cord for the monitor to connect it. This only started happening recently, and after I do this once, the display works perfectly until the next sleep. Is this a cord problem, a GPU port problem? any ideas?

My suggestion is to kill Sleep all together. Systems boot fast enough these days with SSDs that its become almost pointless. Sleep causes more issues than it fixes.

That said, it could be cable related. HDMI has to handle DHCP and it could be that once in sleep when it comes back it no longer has the same authorization.

Do you happen to have a DVI port on the monitor you can try?

Thanks for the reply jimmysmitty. I just tested comlpetely turning off my pc and the same problem exists with that too. So basically whenever the pc goes from "active" to "inactive" i have to take out and plug back in the hdmi cord. I dont have a HDMI to DVI cord laying around, or a VGA cable for that matter, i guess it might be worth trying to buy a new cable.

HDMI is a very finicky standard. I never was a fan of it. I used to have a similar problem with an HTPC I had. If the system even turned the screen off or I turned the TV off it would have me doing the same thing most of the time, it wasn't consistent. I built a new HTPC when the old one died and it seems to have stopped.

It could be a driver issue but I have never had that issue with VGA, DVI or even DisplayPort yet so I think it is an HDMI issue. You could try updating your GPU drivers and even see if there is an official driver for your monitor but I would also try an DVI cable.
