Sorry about this off-topic post - but there does not seem to be a Creative Cow forum for general AJA questions.
So, here it is:
I have a AJA HA5 -- HDMI to HD-SDI Converter. I am using it to capture the screen of a standard PC by using a DVI to HDMI adapter connected to a nVidia GeForce 9800GT graphics card.
When I open a SMPTE Color Bars .tif file on the PC -- the chroma and luminance are almost perfect on my scopes. But when I view the PC's desktop -- or an application like a web browser -- the chroma and luminance levels are completely off-the-charts and in illegal territory.
I don't know the proper way to reconcile these differences. If I use the graphic card's control panel to drop the "PC desktop" levels to a legal level -- I will adversely affect real images and web video that I display and capture from this PC.
If I leave the settings calibrated for the Color Bars .tif -- I'll have to use a legalizer and clamp down on the offending signal levels in an undesirable way.
Anyone have any suggestions?
Thanks
