Hi, Same problem as mine! Are u suing the original Samsung CX511n cable? If not, video will not appear! Buy the original cable!

The simplest way to fix this is to turn it off and turn it back on or unplug the power cable and plug it back in.

Check the cable going from the monitor to the back of your PC and make sure that it is plugged in good. Also make sure your tower is turned on.

that blue light show and error or faulty problem internally or there a problem with in the connection or computer but first check the makers website or manual for troubleshooting.

is the cable a crossover cable

You need a "crossover lan cable" to conect PC to PC

A "lan cable" is for networks

i used a different site as you did not post my problem!

local area connection a network cable is unplugged means the network cable having head connector RJ 45 is not connected.. this is not a error .

If you are sure the left monitor?s power is not the source of the problem it does sound like a shielding or excessive signal loss in a device/cable. If it?s always the left monitor I would try unplugging the video cable that goes from the left monitor and plug it into the right monitor; do the same with the other monitor. If the problem moves to the right monitor then that eliminates the monitors and we move on. If the problem goes away then probably one monitor had more signal degradation than the other. If the problem stays then the monitor is the source of the problem. If the problem followed the cable then I would exchange the cables that run from the switch to the monitors; if nothing changes exchange the cables that run from the switch to the PCs. If exchanging any of these cables results in the problem moving then you have a damaged cable or a bad connection. If the problem is still on the left monitor unplug the cables from the left PC that run from it to the switch and plug them into the right PC; do the same to the right PC. If the problem moves then you might have a damaged switch OR perhaps the video card output on one of the PCs is weaker than the other. All cables and devices weaken the video signal to some degree but the amounts can differ wildly. Over the years I?ve had this problem caused by cables, switchboxes, video cards, radio transmitters, bent connector pins, poor connections, excessive cable lengths, monitors and accumulative signal loss from several devices. The last is the hardest to diagnose. Good luck and let us know what happens.
