Staples $30-60 Envision monitor

[jamarno]

If you bought an Envision model EN-710 monitor and find that there aren't enough user adjustments to make the picture right, there's a second set that can be accessed by pressing one of the buttons while turning on the power. But some of those adjusments can get you in trouble, so you'll want the service manual, which Envision gives out at no charge.
