I have a Westinghouse WDE L40F42 flat screen that has always given me problems with certain set top boxes. The worst was the standard Directv DVR receiver. The tv would flicker and display a "no signal" message when changing channels. This would only happen on the HDMI inputs and not component, composite or RF inputs.
Recently, the same tv started producing a reduced-size window when I would turn-off (not power-off) the tv. My Intel Compute Stick had never had an issue with Win10 Home and Kodi starting from Jarvis 16 to Krypton 17.3.
But, there was a recent Win10 Home Update (August 2017) that started the same behavior on the Compute Stick. The Compute Stick has only an HDMI plug with which to attach to a tv or HD monitor. It can do up to 1080p reliably. I did have Krypton 17.3 Kodi-On-Top installed, but the reduced-size window behavior continued. Yes, the reduced-size window was always on top. It was the headerless, frameless window described in previous posts. Krypton 17.4 did not help resolve this problem and I lost the Always-On-Top feature! Bummer...
But, I had seen quite a few posts on HDMI EDID synchronization in Googling around on the topic. There were older posts suggesting a hardware fix via the HDMI connector. Either tape-up, insulate or remove pin 9 of the HDMI plug or buy an expensive HDMI EDID sync box ($100 plus USD). I did a search for a more recent such hardware-based device and found the following for $22.99USD. It took an HDMI female jack-to-female jack adapter to connect the signal source side to my Intel Compute Stick, but the typical HDMI connection cable was the connector to my tv input. It fixed all monitor issues I was having and seemed to better the resolution, as well.
I don't think this HDMI inline device will work with any kind of sink. You can try it. I surely didn't. I just think the manufacturer mispelled the abbreviation "sync" as in synchronize or synchronization. This the only ding I found in this device. I recommend it highly!
