Anyone seen this before?

Here's the skinny (Optoma HD39Darbee):

I'm connected to my Xbox One via HDMI (into HDMI 1 / MHL input on the projector) playing Destiny 2. In the middle of a match, everything's great and then at seemingly random times, the projector goes blank, shows me the status box at the lower right (Input HDMI 1/MHL: Searching), then I get the spinning circle icon in the center, then my game reappears. This interruption lasts for about 5-10 seconds - seems way longer when you're playing the game though.

Sometimes this interruption happens twice in a row, sometimes just once. Seems to happen at least once in every match I play - but only during the matches (they last around 6-9 minutes each).

More symptoms: When I play Borderlands 2 on the same console, this very thing was happening, but not at random times - it was happening whenever the load screen came up between specific areas. Didn't seem to happen besides then.

What I've done:
- I went into 'Options' and turned auto-input searching off.
- I went into my Xbox One options and changed my color space to the default setting (instead of PC-RGB).

Funny thing is, once I changed that color setting on the Xbox One, Borderlands stopped getting interrupted by the projector input search issue. But after launching Destiny 2 again, I started getting it during matches.

So - I'm hoping someone else has noticed this and there's an easy fix for it. I'd hate to have to return this projector because all else considered, I really do love it.

What say you all?

Is this a direct HDMI connection between the XBox and the projector or is there ANYTHING else between?

Have you tried using a different HDMI cable? A shorter cable? What length is your current cable?

This sounds like a signal dropout issue related to equipment that is not your XBox or the projector's fault.

If the signal drops off too much or degrades too much, then the projector hits the digital cliff (Google: cliff effect hdmi).

You must lower the resolution, use a better cable, or signal equalization to help correct the issue if that is the cause.

The best test is to put the game console within 6' of the projector and a shorter HDMI cable with a direct connection and see if the issue persists.

If it DOES, then it could be an issue with the HDMI connection/main processing board of the projector and it may not be curable. It could be a dirty HDMI connection (rare) or something else more mundane, but rare to have happen. Most often it is video board issues which are costly repairs.

There are about 100 other things within the projector it could be as well.

Good point. I had to think about that for a second. I'm using my Marantz receiver as an HDMI switch - with the main output to the projector across a 20' cable (if memory serves).

There may be a setting I can check in the receiver, but I have no idea what to look for.

I might also try the HDMI 2 input. I don't know what MHL stands for (I'll google that in a second) - perhaps that's adding to the equation...

As far as having a degradation of signal, I've used 3 other projectors in this exact configuration (all of the same hardware) and have never had any indication of a problem like this (2x Vivitek & InFocus).

Thanks very much for the info! Some stuff to try for sure...

So, it's definitely a 25' cable from Sewell (https://sewelldirect.com/certified-hdmi-male-to-male-cable-25ft)

The cable product page guarantees me up to 50 feet, and I've never had any problems in the past with signal degradation that I could tell...

I'm going to try to bypass the receiver and go direct in with the long cable (using the second input on the projector and separate optical audio out of the Xbox to feed the amp). See if that does the trick.

If not, I'll connect it to a shorter cable and test. I'm hoping there's something hiding in the receiver processing that is just mucking things up...

So, I did some digging and found that (*embarrassing info*) a rodent had chewed up one of my HDMI cables (wasn't able to verify the one I've been using, so I assume it might have a nick in it somewhere).

I had a 30' powered Monster cable lying around that I routed through my ceiling last night and tested the game console for a little bit (through the amp this time) - there were no hiccups at all. So, if that's the case through the weekend, I think I can safely say that the cable I was using was the problem, even though 99.9% of the time there was a perfect picture being delivered...

Odd to be so close to the digital cliff where you can teeter like that, but it seems like it might have been the case. I'll know for sure after a few hours-long game sessions with no events.

Thanks for the help!
