HDMI Output Cutoff

Hello
I have two Kona LHi's which are not outputing the entire picture on their HDMI outputs. SDI outputs look fine.

On a Dell WFP2408 monitor it looks like about 21 pixels are missing from both the top and bottom and about 38 pixels off off both sides. The pixels are not getting cut off by the monitor - even in 1:1 mode, a 1280x720 image is cutoff on a 1920x1200 monitor.

On a consumer RCA 42" 1080p LCD, there is a little more picture - only about 15 off top and bottom, 25 left and right.

Based on the fact that 1280x720 Test patterns loaded into the AJA card are cutoff, I am going to say this is independent of FCP. Note that output in FCP has the same issues - SDI is fine, HDMI is cutoff.

Settings? Known problem? Ideas? Some HDMI monitors just do this?

My Machine - OS 10.5.8, AJA 7.0.1, Studio 3, DP QC Xeon Mac's

My HDMI Out settings are:
Primary 720p59.94 (selected)
Secondary 525i29.97
Protocol: Auto Detect (HDMI)
Color Space: Auto Detect (YCbCr 10Bit)
Audio 8 Channels
Output Video Range: SMPTE Range

Thanks for any help!
Mike
