I thought I took all the proper steps to ensure success on my project, but inevitably, I ran into a bit of a hiccup. I'm hoping it's a non issue, but would appreciate the insight of those more capable than myself in this arena.
My setup is as follows: All components (cable box, blu ray, apple tv, mac mini, etc.) are connected to my Onkyo tx-nr709 receiver via 3 foot 28 awg high speed hdmi cords from monoprice (like this
). Then I have a 40 foot 22awg professional hdmi cable from monoprice (like this
) traveling from the HDMI out MAIN of the receiver to the HDMI input of my Samsung Plasma. I also added these
HDMI dongles to both ends of the 40 foot HDMI cord because it was so stiff/inflexible.
Now, I tested this setup for two weeks prior to sticking that 40 foot hdmi in my ceiling, over a bathroom, around piping, behind a shade, .....you get the idea. Everything worked fine as far as I could tell. All blu ray content (1080p/60) was playing as expected. So, I took the plunge and began my cable runs which also included speaker wire for my 5.1 setup. 2 days later, I was finished with the runs. The first thing I did was fire up a blu ray. Everything looked as expected (although I was paying a lot more attention to the sound, because the video picture had been fine for two weeks and I wasn't really concerned). I had to switch some setting on the receiver to get sound through the speakers instead of the TV. As I was doing this and viewing the on screen display of the receiver on the TV, the picture started to go in and out. The screen would begin to alternate between the blu ray content, a solid green screen, and then finally a black screen which would display the number HDMI the Samsung was on (HDMI 4 in my case), as if nothing were connected. I begin to immediately theorize the connections just weren't plugged in all the way. I took the dongles off of both ends of the 40 foot hdmi, turned the receiver off and then back on, but wasn't getting any picture at all. I basically quit for the day, before losing my mind. Tried again the next evening and I got strange behavior for about 15 seconds (blu ray content, solid green sreen, black screen), but then the blu ray kicked in steady and I had no issues. I haven't had any cutting out issues since. I've tried all sources over and over, and even hooked the dongles back on to the end of the 40 foot hdmi. Everything seems to be working as expected. Last night I realized I hadn't updated the firmware on my receiver, so I did. Maybe that was to blame for my earlier cutting out problems. I probably should have updated that before doing anything, but it's just so strange that everything worked fine for 2 weeks and then I had that small hiccup of cutting out, and then everything worked fine with no signs of cutting out issues. Was it just bad connections (hdmi just needed to be unplugged and replugged in again)???
Although I haven't been getting any of the "cutting out", I've began to obsess over whether or not my cable is bad. I'm now watching the blu ray content very closely (like right up to the screen of the tv) and thought I was seeing "sparkles" in the picture. Was watching 'Man on Fire' and I can't tell if its just the way the movie was filmed (its very "grainy" at times). I'm so paranoid now that something is wrong with my HDMI cable. I do see little pixels that flash white in some scenes if I get very close to the tv (its the same scenes, and the little pixels happen in the same place every time). How obvious would sparkles be if I had that problem? I've heard they're normally very extreme, but can also be subtle. Would they appear all the time, on every scene, or is it possible to only see them sometimes, in particular scenes, and only a few very briefly? I think this is all in my head, but I just can't help it after my crises. I always thought if you could see picture on the screen, your cables were good. Am I wrong about that????? I've got a shot to pull another HDMI if I need to, but that would be costly and time consuming.
Am I worried about nothing here????
Sorry for the long post. Any answers/advice/educated theories would be much appreciated.
