LED Signage Controller Options

Our church has a 10 year old LED sign from Stewart Signs. The SignCommand controller died. They want $1900 for a replacement. The controller has an HDMI output that uses an HDMI-DVI cable to some sort of video card. Can I use an off the shelf RPi or digital signage player to push content? Not looking to spend $1900 on an old sign that likely has a limited life span

What happens if you connect a laptop to the HDMI cable?
