Showing jpegs on TV

[#1]

I'm using lightroom 3.6 on my computer and after processing my photo's I tried to show them on my Sony tv.

I keep getting a screen that says " image cannot be viewed". Have I forgot to do something when putting my images on a USB stick?

The image shows on my computer MG_ then a #. MY file says its a jpeg file but with this MG in front of a number.

Can you help if I forgot to do something.

Thanks Brian

It's possible to make a JPEG with a CMYK colorspace, but most programs can't deal with that. Make sure your JPEGs are RGB.

I have lightroom 3.6 set up already in RGB.

Must be something else.

In Digital Photo Professional, I was able to get pictures on my TV by clicking ADD thumbnail to image. Not sure how you can do that in lightroom.
