Worked well with DVI KVM at first and I got full 1080P on my monitor at first. However, after a few days it stopped working. Still works with a direct HDMI connection from any computer, but not through these devices and KVM. It's probably a KVM bug, but I haven't messed with it enough to be sure. Just something to be aware of. The picture quality in 1280x1024 resolution is normal, FWIW.
