Low vision monitor usage

[GreTech12]

Hello!

 

First time poster here. I am trying to set up a couple of larger analog monitors for students that have low vision but I am running into some difficulties with signal quality. As the students have special needs to have these monitors I want to give as clear of an image as possible. The current set up for all classrooms is as follow:

 

Computer VGA output > VGA splitter > Workstation monitor + Document Camera

 

Document Camera VGA output > up to projector

 

The projector has a VGA output but due to the location of the projector and the desired location for the monitors I am getting a very blurry image. I am looking at about 20 feet of VGA cable necessary to put the monitors in their desired location. The projector image is very clear so I used output from the projector to a VGA splitter/booster and then ran cabling to the monitors. This has not worked.

 

The document camera does have a DVI out but I'm not sure if a digital connection would fair any better with the required distance.

 

Please let me know if any additional information is needed.
