Hello again , looks like were not on the same shift .
I will tell you why and how to fix this ;
Your PRO1410 is capable of a 720p resolution but not 1080p that is coming out of your VSX at this point .
The VSX will upscale/upconvert signals to 1080p and the tv/monitor cannot display that and the reason it works when connected directly to the cable box for example is that they talk to each other through the hdmi connection and the resolution auto adjusts for the maximum the tv can take , typically 720p or 1080i not 1080p
No worry there is a way to correct that at the VSX but first you will need to connect it to the tv that is able to display its menu on screen .
Once that is done press the V PARAMETER button and scroll down to RES ,open this and you could first try the AUTO option but you could also select 720P if you want to force it there , otherwise it may try 1080i , the choice is yours but I would suggest the 720p that this monitor was really made for .
By the way check to see that the V.CONV is set to ON in that menu .
