| 423015 | 2006-01-23 05:20:00 | It is possible to operate two conflicting monitors side by side provided that they are both set to the same refresh rate and are operating off the same computer. I rarely disagree with GF, but actually it is possible to economically shield them from each other using a simple three layer shield made of two pieces of 0.5-1mm steel (of pretty much any specification) with a 1mm layer of aluminium between them. The steel will shield the magnetic fields to a certain extent, and the aluminium will provide both an "air" gap between the steel sheets, and the higher refresh frequencies will induce eddy currents in the aluminium which will generate opposing polarity electromagnetic fields which will help cancel out the interference. The focal point for the interference source is the rear of the CRT where the scan coils are located, so I would make a shield that is the height of the monitor and about the same depth as the front to rear dimension. Allow the shield to protrude about 5cm past the rear of the monitors (the front isn't the problem) and is residual interference is present, separate the monitors by a couple of cm. If you want to experiment, just a plain sheet of thin steel (say .25 to 1mm, not 3mm) might even be enough to sort it for you. The field source is very localised. Cheers Billy 8-{) |
