dzzoom Posted January 27, 2010 Share Posted January 27, 2010 Hi hack5 I was told about you about 2 years ago. I have been looking at your site and hoping you can help me out or someone might now what is going on with my computer setup. I have 3 computer working is one in a way if you think about it. After seeing the video on how to use one keyboard and one mouse on more than one PC. I got wild. The 3 PCs are all new and high-end at the time. All 3 have q9600 and 8 GB ddr3 ram. One pc is running 5 LCDs. Yes that is 5 22”lcds. The other 2 PCs are 2 22” LCDs this way I can run any thing I want to and if one PC has to restart for something the other will stay running. Now I was in OKC OK and this set up was running for 1year before I moved. After moving to NYC I am getting some Interference on all 9 LCDs I was thing it might have been the AC power I got 5 UPS to run this all on. But that did not help. I call my power comp and had my house look at. I was told it was form something close to me. Does anyone know of a good DVI cable to use or have some tip to help me out? I do not know how to post a pic to show you my set up. Thank you for your time and help. Sorry for my bad English Quote Link to comment Share on other sites More sharing options...
Sparda Posted January 27, 2010 Share Posted January 27, 2010 How are the monitors connected? DVI? VGA? HDMI? Quote Link to comment Share on other sites More sharing options...

digip Posted January 28, 2010 Share Posted January 28, 2010 I wonder what an EMF detector might pick up in your place. Quote Link to comment Share on other sites More sharing options...
Sparda Posted January 28, 2010 Share Posted January 28, 2010 What does the interference cause the monitors to do? Quote Link to comment Share on other sites More sharing options...
Charles Posted January 28, 2010 Share Posted January 28, 2010 My bet would be increased EMI, due to the cables be rather long. Quote Link to comment Share on other sites More sharing options...
dzzoom Posted January 29, 2010 Author Share Posted January 29, 2010 What does the interference cause the monitors to do? it looks like the interference you on a older TV and some one is on a high power ham radio. lines that runs left to right Quote Link to comment Share on other sites More sharing options...

manouche Posted January 29, 2010 Share Posted January 29, 2010 If the patterning is intermittent it is probably interference, and most likely mains borne. In which case a fairly cheap low-pass filter should sort it out. NB. this is not a transient suppression filter, some mains conditioners are simply that, so check it out (the filtering is normally achieved by opposing coils of the live and neutral mains around a ferrite core.

beakmyn Posted January 29, 2010 Share Posted January 29, 2010 Typical of noise when the cables are too long. The noise is most likely entering through the video cable itself though it could be coming in on the AC. Although I'm relunctant to blame that as once it gets to the monitor is rectified to DC. I would try putting a ferrite core on one end of the video cable see if that knocks down the noise. Try a shorter cable to see if the noise is on the cable or power.

subl1m1nal Posted February 1, 2010 Share Posted February 1, 2010 Could also try updating the video card drivers on the PCs. But because it's all the monitors on different systems, this is not likely. Quote Link to comment Share on other sites More sharing options...
