Everything works fine except for the HTPC which is an i5 Intel NUC. Upon selecting the HTPC source I get a " Mode Not Supported - Please change the resolution of your external device " appearing on the telly. This appears to be a samsung tv message and not a denon receiver message. Tried different powering on sequences but no different. I do hear the windows startup jingle however.
If I bypass the HTPC and plug directly into the telly HDMI - it works just fine. To get audio I then needed to play around with ARC to get sound back through the external speakers. I understand what's happening and what buttons need pressed but the mrs is having some issues with all this. She just likes simple and wants the HTPC to also go through the amp.
Upon lots of googling I found a samsung page (http://support-us.samsung.com/cyber/popup/iframe/pop_troubleshooting_fr.jsp%3Fidx%3D153003) suggesting the refresh rate should be a minimum of 60hz. - So not the resolution but the refresh rate ? Checked and its currently 29hz. The HTPC has identified the TV just fine but has set a very low refresh rate. Changed this and for the first time appeared to get sound and vision through the receiver - but not sure if this was more to do with the multiple plugging and unplugging of HDMI's
Rebooted the PC and back to the "Mode not supported screen". Swapped a few HDMI cables around. Got the desktop back onscreen and checked the refresh - it's back at 29Hz - THis is under the intel display graphics software.
If I check through the normal display mode under control panale and look at the generic pnp monitor prorperties it has it set at 59Hz.
So I'm getting a bit frustrated and going around in circles / not fully understanding what the problem is.
Any suggestions to try or things to play around with to resolve this ?
