EPG and live TV overscan on PC.

Running
Windows 10
Kodi 17.1
NextPVR 3.9.2.161119
2560×1440 16:9 LCD Monitor
ISB TV tuner.

First problem is that Kodi doesn’t display the complete fee to air TV guide for all channels. When I update and view the EPG in the NextPVR app it displays the full 7 but in Kodi the EPG only shows 3 or 4 days for the for the networks. Any way to fix?

Also. Can Kodi update the over the over the air EPG for all channels? Normally I just updated the EPG for TV manually through NextPVR.

Second problem is when I watch live TV the top of the picture is a flashing white line. I think it has something to do with overscan not being supported when watching TV on a PC monitor like it is when watching on a stand alone LCD TV. Any way to remove this annoying flashing line when watching live TV through Kodi with NexPVR?
