  • Hey all, just changed over the backend after 15 years I figured time to give it a bit of an update, its probably gonna be a bit weird for most of you and i am sure there is a few bugs to work out but it should kinda work the same as before... hopefully :)

HDMI to HDTV problems

1080p

1080p

"Input signal out of range. Change settings to 1920 x 1200 - 60 HZ"

Well 1080p over HDMI isn't going to work to a P.C monitor as its looking for a 60Hz signal, and 1080p will typically be at 23.98 Hz. Hence the choice of 720p as a video preview format.

I have a 30 foot HDMI cable plugged into an LG LBD2DE 1080LCD and works perfectly in both 720 and 1080.

Best advice is bring your RED in with you when testing monitors and try them all.

That is the best policy, Jim. The HDMI output works with a wide variety of HDMI and DVI equipped televisions and computer monitors, but you should verify operation with a specific monitor. If a monitor fails to operate as expected, we recommend checking the resolution (try 720p output instead of 1080p) and the frame rate. After that, the next step is using a HD-SDI to HDMI converter.

Long story short, I hear the argument that "all DVD players push via HDMI to my monitor". But just like with our CF CARDS, not all monitors can handle what we are pushing from the RED ONE. You will need to trial-and-error until you can find one that can.

I setup a Red using my Sony computer monitor and it was able to produce a pictures using an HDMI -> DVI adapter. The monitor is a 20" SDM-S205(F or K)

I'm only testing the monitoring out from the live camera, not playback, so I'm only checking the 720p condition. The monitor was happy when it got a 1280 x 720 feed, but when I turned on the menus it got a 1280 x 853 feed and couldn't synch up and produce an image. The monitor happily scaled up the 1280 x 720 to 1600 x 1200 and would also display 1280 x 720 pixel for pixel.

Unfortunately, I didn't check to see if the monitor reported frame rates for the signal. It has a menu that shows the input signal characteristics. I'll have to set it up again and try some more tests.

I was happy to see that the HDMI could be used with the right equipment.
 
Same issue here, I just posted another thread about it.

Some observations.

The HDMI works fine if its to an HDMI input.

It crashes the camera if theres anything coming back up the HDMI cable.

On a Panasonic Viera TV the camera works fine conected to the TV until the HDMI I/O is made live then it crashes the camera. its not cable length but what ever the TV is sending back up the cable or handshaking or whatevers going on.

HDMI to DVI cables also work fine for what its worth.

The Panasonic TVs use their HDMI connections to communicate with other Panasonic AV gear for remote control. I suspect it is this communication that crashes the camera. There is obviously something in the HDMI specifications that allows manufacturers to use HDMI in this way. I think Red needs to make the camera's HDMI port 100% compliant so it isn't crashed by these common signals.

The DVD player analogy is a good one. A device with a properly implemented HDMI output should be as simple as plugging in an HDMI DVD player.

Im sure this is it, please can the ball now be in Red's court to advise.

thanks,

Shooting on Build 17 v3.3.9 today using a Samsung Syncmaster T260 connected at 50Hz through HDMI. Worked for the last shoot and worked for the first six hours of this one, then suddenly started giving problems although seemingly nothing had changed.

Rebooting/unplugging cables didn't work, but we eventually got it to work again after switching off the monitor for a few minutes. It seems the best solution is to buy the Aja converter before risking upsetting clients.

I have a section in the Menu of my Panasonic Plasma that says control with HDMI. You can turn this feature on and off. Maybe this is the problem?
 
I just got one of the new Dell 2709W monitors with HDMI input. I was hoping to be able to use it for monitoring onset, but my RED just hangs when I connect it (with a 1.5m cable). It works fine when I connect to my 32" Samsung TV. I think it's frustrating to get a "try some different ones and see if they work"-answer to this question. I think it would be a great idea to start a thread with a list of panels that have been tested and work with the RED ONE. The best would be for someone from RED to moderate it.

This is a good idea.

Try using hdmi to dvi and I think you might get different results.

I think this will work fine, Ive had no problems with HDMI to DVI cables, even the cheap ones. Also very long 10M plus in to a passive HDMI to DVi convertor.

Does anyone have access to the HDMI spec to see if there is a way to disable the offending signals by disconnecting some pins on the cable? If there is a dedicated line for these control signals it could conceivably be disconnected.

Im guessing but if its the Control stuff I think its called CEC on pin 13. We need an expert to comment on this it looks complex.

Consumer Electronics Control channel
The Consumer Electronics Control (CEC) channel wiring is mandatory although implementation of CEC in a product is optional.[64] The CEC channel uses the industry standard AV Link protocol, is used for remote control functions, is a one-wire bidirectional serial bus, and was defined in HDMI Specification 1.0 and updated in HDMI 1.2, HDMI 1.2a, and HDMI 1.3a (added timer and audio commands).[65][66][67][68]
The CEC feature is used to allow the user to command and control multiple CEC-enabled boxes with one remote control and for individual CEC-enabled boxes to command and control each other without user intervention. An example of the latter is to allow the DVD player, when the drawer closes with a disk, to command the TV and the intervening A/V receiver (all with CEC) to power-up, select the appropriate HDMI ports, and auto-negotiate the proper video mode and audio mode. No remote control command is needed. Similarly, this type of equipment can be programmed to return to sleep mode when the movie ends, perhaps by checking the real-time clock. If it is later than 11:00 p.m., for example, and the user does not specifically command the systems with the remote control, the systems turn off on command from the DVD player.
Alternative names for CEC are Anynet (Samsung), Aquos Link (Sharp), BRAVIA Theatre Sync (Sony), Kuro Link (Pioneer), Regza Link (Toshiba), RIHD (Onkyo), Simplink (LG), Viera Link/EZ-Sync (Panasonic/JVC), Easylink (Philips) and NetCommand for HDMI (Mitsubishi).

This is an interesting theory. Can anyone do a test i.e turn these commands off on their HDMI equipped Panasonic plasma and see if this does in fact make a difference ?

The Panasonic plasmas that I have access to are the "industrial" models and these work fine.
 
If that's the case then what's the problem with my Dell 2709W not working? I have a hard time understanding why every other audio/video hardware company makes it work when it's so hard to get the RED to work. Is the HDMI controller in the RED just not up-to-par?
