Canon 5D Mk IV HDMI Out Not Working

weekleyba — Sun, 04 Dec 2022 13:21:00 GMT

I've purchased a new on-camera monitor for my 5D Mk IV and I'm not able to get it to work. Just says "No Signal". The monitor works on my 70D just fine. I've searched the web for answers but have found none the fix my problem. So far I've tried disabling the Wi-Fi/FNC function and reseting the camera to factory defaults.

Does anyone have any advice?

I should add, I've never used the HDMI out before on this camera, so I guess there's a possibility that there is something wrong with it.

If does [sound] like a potential problem with the HDMI port. If you have any AC adapters connected, try disconnecting them. If it is still a “no-go” on battery power only, then your camera may need a visit to Canon Service Center.

Greetings,

I don't have a 5D4. It will output 1920 x 1080 over HDMI. You need to disable display info on the Camera <menu 5> HDMI menu, and match the output, codec and frame rate of the camera to your monitor.

If this doesn't help, Waddizzle repair suggestion is best.

What frame rate are you capturing your footage in? Depending upon that, the output signal will be different. So you'll need to check out your monitor's information/manual on what signals it supports.

The monitor I bought is Timbrecod DC-56. Here is the list of signals it supports. See image below. Can anyone tell me which one I could use for the 5D4? I've tried a few but no dice. Also, what should the following be set to on the 5D4:

HFMI Frame Rate (59.94i, 59.94p or 23.98p)

Movie Rec Quality

Aspect Ratio (for photos)

I changed my Video System selection to For PAL. This gave me the ability to see HDMI Frame Rate of 50.00P & 50.00I and Auto. Still "No Signal".

I wish manufacturers would stop rounding values. I'm assuming that when that product shows 1080/60p, they really mean 1080/59.94p. Also instead of 30 and 24, they really mean 29.97 and 23.978

Anyhow, what frame rate are you using when capturing your footage?

About the only other thing I can think of leading to no signal (aside from your HDMI output being bad) is the cable. Some newer HDMI cables are "active" and there's a certain direction you can use them in (ends are marked with "source" and "display"; make sure the "source" end is connected to your camera). I always use passive cables myself that can be used in any direction.

All of the discussion about frame rates and recording has left me totally confused about what exactly is the issue.

If you connect the monitor in photo mode, can you see the menus from the rear LCD or not?

I've tried all frame rates. No dice. The cable should be good as it works with the Canon 70D.

I'm thinking the HDMI out has a problem.

No matter what I set in the menus, (HDMI Display, etc.) the camera rear display goes black, when the monitor is plugged into the HDMI out and then powered on. Doesn't matter if it's photo mode or video mode, the rear LCD goes black and the monitor always reads "No Signal."

I'm starting to think, I need to send it in. Unless you have any other ideas...I'm all ears.

Let’s not get ahead of ourselves. We need to figure out if the HDMI port on the camera is functioning.

Reset the camera to factory defaults. Do not change any settings. Set the camera to photo mode. Connect the camera to a different monitor. Try a television with an HDMI input.

Good call Waddizzle. I connected it to my TV through the same HDMI out and cable and it works. It worked on photo mode and worked on video mode. It worked even when changing the HDMI frame rate to any of the three in the camera.

So perhaps my camera's HDMI out is good...? Where does that leave me?

Did you reset your camera beforehand?

If the signal is going to your TV, then yes, the HDMI out on your camera and the cable are good. That though shows that either your external monitor is faulty, or it's not compatible with any of the signals it is receiving.

“So perhaps my camera's HDMI out is good...? Where does that leave me?”

I would conclude that the HDMI output and your HDMI cable are good. The fickle finger of fate is pointing at your portable monitor settings.

Most consumer TVs can auto-detect the HDMI signal and display it properly. What is the TV reporting as the frame rate and frequency? Time for another deep dive into frame rate settings on your portable monitor.

Yes. I did reset the camera. I'm thinking the monitor is not compatible with the 5D4.

Here's an image of TimbreCod DC-56 and the 5D4.

No idea on how to find the frame rate on the TV. I cannot find anything on the frame rate settings on the monitor. I'm going to try and return. To bad. I really like the design with the integrated battery and slim design.

Any recommendations on a small 5" monitor for 5D4?

Re: Canon 5D Mk IV HDMI Out Not Working

Waddizzle — Wed, 07 Dec 2022 12:41:20 GMT

I was only interested in the resolution of the HDMI signal on the TV, not the frame rate. Once we can nail down a resolution, then we can eliminate many of the supported formats on your chart.

I am surprised you monitor does not auto-detect the HDMI signal coming out of the camera.

Re: Canon 5D Mk IV HDMI Out Not Working

At this point, I going to punt and try and return this monitor. A monitor should not be this difficult to connect to a camera. There has to be something else out there that can auto detect the signal and just bring it on screen.
If you all have any monitor suggestions for the 5D4 please send them my way.
Also, thank you all for your help on this matter!

I've never used any external monitors, but it appears that two very good brands are Atomos (their Ninja product) and Blackmagicdesign (their Video Assist product). Both have 5-inch versions for HD capture.

The main reason I started looking for a monitor is to shoot basketball and volleyball shots right on the floor. With a monitor I would not have to lay down on the floor, but simply put the camera on the floor and look at the light view through the monitor to take my shot. anyway thank you for the suggestion.
