30in fun
Switching the DVI cables on the ATI setup for a longer run - which, incidentally, paired with our Avocent 4SVDVI10 results in artifacting - didn't cause any problems.We then ran Enemy Territory: Quake Wars on both setups, at several resolutions, to make sure the KVM and display were correctly switching resolutions - again we had no issues with either card.
Running our Company Of Heroes: Opposing Fronts benchmark, and switching the focus to the other source didn't cause any untoward effects, either. We explicitly mention this because using the Avocent 4SVDVI10 we would sometimes see ATI cards crash out of benchmarks when the KVM was focussed on another system.
30in fun
Switching from our 24in to our 30in Dell, we found that if you started either system without it having the being the active connection for the KVM, the display would not switch-on correctly. The 24in Dell didn't see the problem occur, though. As such, the problem seems tied to the 3007WFP, or dual-link signalling is not emulated in the way single-link is. Our Avocent 4SVDVI10 switch experiences this issue, too, not only on the 30in, but also the 24in, so at least the ATEN CS1782 is a step in the right direction.Firing up our Company Of Heroes: Opposing Fronts benchmark at 2,560x1,600 again saw neither artifacting nor unexpected crashes when the KVM focus was away from the system running the benchmark.
Lastly, playing a Blu-ray film on our Radeon HD 3870 system, we saw the 3007WFP playback Pirates Of The Caribbean: At World's End without issue, indicating the ATEN's HDCP support. However switching the focus of the KVM to the other system would cause playback to cease as the player lost the HDCP connection. Knowing this, when playing back HDCP-protected content you cannot switch focus between systems.
