We run that screen on a KVM switch manufactured by D-Link (DKM 4U) and had some trouble with DVI. Later we realized it's all about your GNU/Linux' kernel and DVI support. Since we use Xubuntu 8.04 (HH) on workstations and Ubuntu Server 8.04 (HH) and KNOW some/lots of people like DVI we recommend you to stick with analog signal transmission though! It eases some things up and reduces your workload drastically (connect stuff, maybe update xorg.conf and auto-adjust). The screen however is inexpensive and provides you with good quality.
