Hi, first of all, i'm building a Component to VGA Conveter using the LMH1251, after reading some docs today i found out the horrible truth about the LMH1251, it doesn't support 1080p resolutions at more than 30 Hz! So, I tired to calm down and think rationally. My first logical decision was to use the common LM1881 Sync separator, but in the datasheet it doesn't say if the LM1881 supports HD, the next possibility was using an LMH1981 which supports HD according to its datasheet, but its application circuit is really complex and I would have to redesign the PCB I made for the converter. So, to make it clear, my question is: Does the LM1881 support 1080p resolutions at 60 Hz? Thanks for your time. EDIT: After reading the LM1881 National Samiconductors info Page, it says that it doesn't support 1080p resolutions.
If I may ask, what will be connected to the RGB/VGA port? With 1080P only an old high res CRT projector comes to mind. The only ready to go solution I have found seems to be the Spatz Digiscale http://www.spatz-tech.com/spatz/digiscale.htm Don't ask me, what chips it uses *g A Forum for AV nerds might be more helpful?! There are probably more people with a need for this. But please post any progress here. :icon_bigg
