Need help in schematic design (IMPORTANT)

I mean the effect of extra load on the signal could lead to slower step response, especially if you have a load which sinks much more current than a logic port, like a LED does. Besides, longer or branched traces can lead to signal overshoot or ringing.

Those are usually not a great problem if you work at low frequencies, up to a few MHz but you must pay attention if you plan to drive the interface in the tens of MHz range.

Please note that I don't know how are you going to connect the ADV7123 device. I assumed you DO actually have leds and 7seg display connected in parallel to the interface signals. Maybe I missed the point and you are simply keeping the original signal names but no led is anymore there.
