Roku / Insignia / Intel HTPC HDMI issues
Not sure if there's a solution to my problem, but wanted to post to see if anyone else has experienced this issue and perhaps to document it for others who might see this issue in the future.
I have a new Insignia 55" LED TV model # NS-55D420NA16. I also have an HTPC based on an Intel DH67GD motherboard. Both work great together with the HTPC outputting 1080p through HDMI. I added a Roku 3 to the system and am now having issues switching sources. Once I switch inputs to the Roku when I try switching back to the HTPC I will get a static screen that intermittently blanks out - like the TV is having issues syncing to the source. This happens very consistently. There are 3 ways to get the signal back:
1 - Power the TV off then back on. The HTPC will then display fine.
2 - Unplug the HTPC's HDMI cable and plug back in. The HTPC will then display fine.
3 - Unplug the Roku's HDMI cable, then switch sources to an empty input, then back to the HTPC - and the HTPC will display fine.
If I then switch back to the Roku and back to the HTPC the same issue will occur.
Here is what I have tried:
- Multiple different HDMI cables for both devices. Same issue.
- Swapped HDMI inputs on the TV. Doesn't matter which inputs I use, the same thing happens just as described.
- Returned the TV for a new one, thinking it may have been defective. Same issue.
- Swapped the HTPC for an HTPC running an Intel DH67CF motherboard (same chipset but different board). Same issue.
- Swapped the HTPC for an HTPC NUC model # D34010WYK which has Intel HD Graphics 4400. Same issue.
- Tried both the HTPC and Roku on a different model Insignia 55", model # NS-55D550NA15. Same issue.
- Swapped the Roku for an Xbox 360. The problem does not occur when switching between the Xbox and HTPC.
- Swapped the HTPC for an Xbox 360. The problem does not occur when switching between the Xbox and Roku.
- Tried the HTPC and Roku on a Samsung 22" LED TV and the problem does not occur.
So, I feel like I either have a defective Roku that is messing up the HDMI switching on my Insignia TVs under certain circumstances (unlikely), or I have found some kind of odd compatibility issue between Insignia TVs (2 different models), Roku 3, and Intel graphic chipsets (2 different models).
I am running the latest BIOS and drivers on my HTPCs, latest firmware on my Roku, and there is currently no firmware update for my Insignia TV.
I'm at a loss on what to try next. One option is to return the Roku. Maybe it's defective? Or go with a different player altogether.
Another option is to return the Insignia TV AGAIN and try a different brand, but that does not help if I want to add a Roku to my older Insignia TV.
