LCD defeated by HDMI or mini USB

sharpt — Mon, 30 May 2016 17:20:58 GMT

The LCD on my Canon T5i goes black when HDMI or mini USB is plugged in. Thoughts?

Merely "plugged in", or do you mean when something is connected to the other end, too?

What does your instruction manual say about it?

If you plug in an HDMI cable camera assumes you want to display on TV so it shuts off LCD.

Merely plugged into the camera

It does display on the TV (though not camera) but then it doesn't convey audio - through either mini USB/RCA or HDMI. Is there a setting to fix these problems?

Okay. I'm pretty sure that is normal behavior for both ports.

I can't help with that. You could call Canon at 1-800-OK-CANON

Those are not "problems", not at all. I'm not sure if the T5i even has "Audio Out". First and foremost, it is a still photo camera, not a video camera, which is a different device from a camcorder.

I've been viewing YouTube videos to monitor headphones. Several explain how that can be done with the mini USB out to RCAs to a mini plug (sometimes with an amp between).

Canons appear to be used in some of those videos. Also if you're not able to send audio through either of these cables, why do the ports exist?

It does have audio out.

Tell me more

Not much to tell. If you are using official Canon cables and connecting them properly you either need to 1. Verify TV settings, 2. Turn up TV volume, 3. Or call Canon for assistance. Mine works fine when I connect to TV.

You have to use the wiredly shaped AVout cable that connects to the USB port.

The one for my T6S - which is prbably the same is the AVC-DC400ST

Just talked with Canon. Keeping the LCD on while attached to the HDMI is called screen mirroring. This feature is permitted only on the higher-priced cameras 😞

Also, headphone monitoring is not available except on the higher-priced cameras and camcorders because you can't sell more expensive cameras if you offer even pretty basic features like these on the T5i/Rebel series.

Magic Lantern doesn't solve this problem either as no audio menu appears on the build for the T5i.

So - boo Canon for dumbing down the T5i but I'm ok with ML for uncovering what features it can. Please add the audio menu to the T5i (particularly the headphone monitoring option) in the next build.

"Keeping the LCD on while attached to the HDMI is called screen mirroring. .... Also, headphone monitoring is not available except on the higher-priced cameras and camcorders because you can't sell more expensive cameras if you offer even pretty basic features like these on the T5i/Rebel series."

Adding those features probably requires doubling up, and duplicating the HDMI signal circuitry, which would significantly raise the cost to build it. Ditto, for the audio. Not everyone will be using the cameras in that fashion.

If you want the more advanced feature, then you have to pay for it. The Rebel series of cameras are entry level performers. They are mostly targeted at people who are upgrading from a camera phone, or a point and shoot.
