I am currently using an ADV7393 in 8-bit 4:2:2 YCrCb mode using the BT.656 input standard and driven by a Spartan 6 FPGA. Initially, the device outputted an analog signal to several differnet monitors with no problems. However when attempting to capture video using a USB2 capture cable/card, we see distortion in the upper part of the display. One customer is also complained of a similar distortion on his monitor. Has anyone else experienced this? What could cause the analog output signal to display diferently on different monitors? Note: The test pattern output from the device works properly on all monitors.
