Da-Lite's borders are painted on. I know you can get wider borders upon request, however, since they are painted, making borders wider may increase the risk of edge curl. You should call Da-Lite for a recommendation.
That's kind of what I thought but the initial odor from the new screen definately smells like dry-erase marker not paint. Wondering if this is what they use to prevent screen curl, and if so, any suggestions on a DIY job to increase border size.
