Be careful to avoid image quality problems (parasites various types flashing blue pixels) care not connect DVI cables are too long especially in high resolution (1920x1080).
Tests conducted (sources: 1pc + 1 dvd platinum screen: NEC MultiSync LCD EA231WMi native 1920x1080 resolution)
- Dvi cable with 5 meter output (2 + 2m dvi input, or 7 meters of cable between the two sources and the screen) displaying >> corruption issue in 1920x1080 (pixels flashing blue on dark backgrounds or red), forced to lower the resolution to 1600x900 to find a proper display, all intermediate resolutions (1680x1050 and 1776x1000) display also had corruption problems.
- Dvi cable with 1.5 to 2 meters output (2 + 2m dvi input, 4 meters maximum cable between the two sources and the screen) more >> display problem in 1920x1080.
So aside from the limitation of the size of dvi cables, overall satisfied with the product (quality of unscreened RCA audio switch)
