Weird Screen Resolution Change With Pioneer Receiver
Hello! I have a bizarre display issue I've been struggling with for... jeez I don't know, at least 3 years now.
**Symptoms**: When entering or exiting fullscreen on Chrome or VLC (It's a HTPC so that's about all I do on it), the screen cuts out for a moment, and cuts back in at a new resolution. It happens inconsistently- sometimes it will change to a lower resolution and just stay there indefinitely. This can be short-term fixed by restarting the screen or the whole PC.
For most of the time I've had this issue, I didn't realize that what was happening was resolution change. It's only since I've got my newest TV that I notice when things drop to low-res and het all pixely.
**The setup**: Windows 10 PC with a Nvidia geforce gtx 760. Drivers are up to date. HDMI goes from the PC to a Pioneer VSX-822 Receiver, which then sends the video to a Sony Bravia 45" television via a second HDMI cable.
**Suspicions**: For a long time, I thought it was the screen, so I just gave up after tinkering with display settings. A few days ago, I swapped the TV out for the Sony Bravia that I just purchased- no change.
Some friends suggested it could be the HDMI cable, so I swapped that out. No change.
I found [this article](https://answers.microsoft.com/en-us/windows/forum/all/why-does-my-monitor-change-resolution-when-going/3f501051-1911-424e-a1de-9afd8f46fce2) which describes very similar symptoms and was originally posted around the same time I noticed my own, but the fixes in the comments didn't help.
**Revelation**: So the act of typing this out alerted me to some configurations and potential fixes I hadn't yet considered- like plugging the TV directly into the PC.
Bingo. Issue is gone. The Pioneer VSX-822 is doing something with the signal that is causing the problem. The TV itself goes black for a brief moment when the resolution changes, and so I wonder if the Pioneer is telling the TV to do something it's not supposed to do. Haven't figured out WHY yet- [the manual](https://www.pioneerelectronics.com/StaticFiles/Manuals/Home/VSX-822-K_OperatingInstructions062612.pdf) I found has some information about changing the resolution, but that seems to only be a menu option for a Pioneer model I don't have.
Does anyone have any insight?
