What are you sending, RGB or YCbCr from your PC to the EMO? I have tried to get this PC to default its output to YCbCr but cant find anything in the Intel onboard video settings to do this, but I am not sure this would help but I'll try anything short of a motherboard replacement at this point I am running a projector with a dvdo iscan pro video processor which does not have CEC, tried a Panasonic plasma with viera link (CEC) enabled and disabled- no difference. Tried a computer monitor with HDMI,no CEC, same result. CEC can drive you crazy but I am pretty sure it's not the culprit here. Interesting...I have my HTPC sending a signal via a DVDO iScan Duo which in turn sends YCbCr to the XMC-1, when then goes to my Panasonic plasma. Sounds like we have a very similar setup. Have you tried any of the following: 1. Cycling between the different chroma subsampling setting (4:4:4, 4:2:2 and 4:2:0) 2. Have you tried disabling deep color 3. Have you tried bypassing your video processor completely I don't suggest any of this (especially #3) as a permanent solution, but as a troubleshooting step.

I'm experiencing a very similar problem - I think it is identical except that my screen never flashes up.
Originally was PC -> XMC -> Lumagen Mini -> JVC RS-45...I turned on video-on-standby and switched to PC->XMC->Projector but same behavior. Previously worked fine with UMC-1.
I'm currently working with support but figure I'd post some info here to see if we can have more luck...
Specifics: Samsung laptop - Win 7, w/ Intel HD3000 + nVidia (GT525M) - verified current on all drivers and firmwares Video mode is 1080p60 connected to XMC-1 input 3 (vid-on-standby enabled) connected to JVC RS-45 (verified latest firmware) Path: XMC powered on Power on laptop Switch input to laptop Get blank screen on projector(laptop display is also blank - laptop thinks it is outputting to HDMI) Unplug HDMI, Replug HDMI, and screen displays on projector Switch XMC to input 1 (Oppo) Switch back to laptop Get blank screen on projector(laptop display is also blank - laptop thinks it is outputting to HDMI) Unplug HDMI, Replug HDMI, and screen displays on projector Power off laptop (leave XMC alone) Power on laptop Screen displays correctly on projector once booted

Ran an additional test - exact same except I swapped out my Samsung laptop with 2 different other laptops - both of these 2 laptops worked correctly:
1st one was one of the last of the 17" Macbook (nVidia graphics) running osx 2nd one was a newer 13" Macbook (Intel graphics) running Win7

Like you, I have tried 2 other computers and they work OK through the XMC, it's just this one with Intel HD 2500 onboard graphics that refuses to output on the HDMI when the XMC switches inputs. No problems with all other AVR's that I have tried, just the XMC. Problem still ocurrs when I have the HTPC in Bios settings mode which eliminates any chance of windows causing this. Tried an older video card (8800GT) and that resolved the problem but this card is has DVI only thus does not support audio. I will be trying motherboard, CPU swaps to get to the bottom of this, but this problem is definitely a incompatibility issue on the XMC side of things. I also was working with tech support but no solution there.

So got OPENELEC.TV running on the projector but it did not solve the issue - switch the XMC to another input and back and the screen is blank till the HDMI cable is removed and re-inserted. A friend brought over his Dell with a nVidia 720 card in it (I think) and it worked correctly - seems to be tied to specific hardware... Maybe the Gods are telling me it is time to upgrade :-P

If you have got a Harmony remote and an Infrared receiver for your laptop, you could try to program the Harmony that the laptop will be switched to Hibernation mode when not selected as input source. But when selected as input source the laptop will be switched on again.

But when selected as input source the laptop will be switched on again. This does not help the issue - if I start with a fresh boot of the XMC-1, switch to the PC input, and then power on the PC, I do not get the video - I must unplug the HDMI. Then as long as I stay on that input it is fine until a full-off (not standby) of the XMC or an input switch.

Why not try sticking a Video card in the HTPC and try that? Sincerely, /b

The OP might have the option of a new video card, unfortunately mine is a laptop so I am stuck short of finding a fix or replacing it Although I was considering replacing it anyways It's not my fault I spent too much this month - Emotiva MADE me by a new HT Computer... EDIT: BTW - every machine but my one laptop has worked so I would put better than even odds on a new video card fixing the issue (just buy it from someplace with a good return policy just in case)

I seem to remember the INTEL 2500 had compatibility issues from day one . Google INTEL 2500 INCOMPATIBILITY ISSUES WITH HDMI.
I see you have purchased a new machine. Never mind.

BIGTIME! and the HDMI is stuck with YCbCr chroma sub sampling as you can not set it to 4:4:4 RGB. HTPCs with that video chipset are door stop trash bin items sorta like a TV without dot per dot pixel address and overscan turned on permanently.

Just found out this happens with a Mac Mini output (earlier version, with cable to HDMI connection). Same Mini will connect directly to the TV with no issues. So, it is not just a Windows issue.

Further testing seems to point to an XMC-1 compatibility problem with Intel onboard video. Test motherboard was a asrock Z77-PRO4, I tried 2 different Intel i5 CPU's, one with HD2500 graphics and the other with HD4000 graphics. The XMC-1 will not lock onto either graphic types once the inputs are switched, unless you physically remove and reinsert the HDMI cable.
Both HTPC's have no problem with other brands of AVR's.
The final solution for me was to install a Radeon HD6450 video card and abandon the onboard Intel video altogether. IMO this is a bug, which could be easily resolved through a firmware update if EMO was willing. But HTPC users are in such a small minority and unless other HDMI incompatibility issues become evident I would recommend to be prepared to modify or change your computer if they have onboard Intel HD video.

Which will most likely have intel HD graphics. Open up support tickets. I know some of the Emotiva staff have Macs (from previous posts) so this should be easily checked.

I tested with multiple machines (including my own Macbook Pro 13" non-retna) with Intel graphics and they worked fine. Might be just older versions or may be something more complex...not sure... I ended up upgrading from my laptop to a new dedicated HTPC and the new machine works fine (I wanted to upgrade for awhile and this made the perfect excuse). For those keeping score, the following have worked here: MacBook Pro 13" (non-retna w/ Intel graphics) MacBook Pro 17" (w/ some sort of GPU - would need to look it up) Dell with a GeForce 635 My new home-built machine with a GeForce 750ti - specifically I got the EVGA GTX750TI card (Intel video totally disabled) The ONLY failing machine is my Samsung Laptop (i7 w/ HD3000 graphics) - specifically it is this Woot special from Oct 2011: www.woot.com/offers/samsung-15-3-quad-core-i7-laptop-with-widi-wimax-blu-ray-and-hd-led-displayI still have the laptop so if anybody has a test I can easily run, I'd be happy to...would be nice to get to the bottom of this.

I'm having the exact same problem except it is not with the Intel graphic. I have a AMD R9 280x video card on an Asrock z87 motherboard. The computer is on HDMI one when I switch input and come back to HDMI 1. The screen of my TV is flashing and HDMI handshake is not done. I need to unplug and replug HDMI for handshake to happen.
If if I put the computer into sleep mode, and waking it up only after being back to HDMI 1, it works.

Jeex, Try switching inputs on the XMC. When you switch the input, it will force a new handshake. In fact, by the nature of HDMI an the handshake, any changes along the chain should force a handshake of the complete chain. This should be a slightly easier fix then removing the plug and putting it back in.

Do give it a shot (and report back for the record) but in my case, switching inputs CAUSED the issue...only unplugging and re-plugging while staying on the input fixed it...
