Many of you have a an HTPC, HDTV and a receiver all controlled by some type of universal remote…am I right? Well, I have a couple and one problem I’ve had since the beginning is with my living room HTPC and Samsung plasma. They just do not get along. If the TV does not power up and initialize before the video card does, I never get out of the ‘No signal’ display and have to do a sleep/resume cycle on my HTPC again in order for it to work. I even added a custom power command on my Harmony 880 just to sleep and wake the HTPC and nothing else to resolve it. It’s still annoying, however.
What is happening is, although ATi claims to have fixed this forever ago, that my HD 2600 card is not able to retrieve EDID information from the TV if it has not completely powered, warmed up and initialized before the card requests that information. So, it remains stuck on ‘No signal’ since no handshake took place. Setting the power up order for my devices and configuring some wait states helped reduce the number of times it occurs, but it still happens with some frequency.
Today, I believe I have solved my problem. I found a smal application called hdmiON that basically sends a command to reboot the monitor (TV in this case). This causes EDID information to be resent, reinitializing the display and giving you a puicture instead of the dreaded ‘No signal’ message.
One problem is running it, however. I don’t fully power down my systems, so I can’t simply throw a shortcut to this little application in my startup folder. I need to run it upon resume from standby. So, I found another small application that fits that bill…it’s called Hibernate Trigger. When running, Hibernate Trigger can be configured to run a program on sleep, resume or both concurrently. I simply placed Hibernate Trigger in my startup folder so it runs on every boot, configure it to execute hdmiOn upon resume and then let it quietly run in the background. Problem solved!

I had the same problem before but the ATI drivers fixed it. What I was doing until then was using one of the colored buttons on my mce remote to launch hdmion but I think the hibernate trigger may work better.
According to ATi/AMD, that issue was supposed to have been resolved as far back as Catalyst 7.3, but I see the issue still exists with many (including myself).
I thought of mapping something to a key on my Harmony, but I only found ways to do it using Girder (or similar), which I don’t feel like fooling with.
I’ve not had a chance to put it in action yet, but I’m confident it will solve my little annoyance.
Oooo this looks good. I’ll check this one out tonight! Thanks. :)
