set the monitor to REC709 and the monitor out of the Alexa to REC709 also. Make sure not to record REC709 if you want LogC recording.
The "REC709" out of the Alexa is a bit low in contrast, I think to allow some grading of the image. But it's way better than viewing LogC on the director's monitor.
There is no easy way to to view in a more traditional REC709 mode (to look like a tv camera). There is an app called "Arri Look Creator" that you can download from Arri. But it can only modify the REC709 already in the camera, and with crude controls (lift, gamma, gain, saturation - no curves). You can't up-load a LUT to the Alexa, but I believe you can to the Amira.
The "Arri Look Creator" requires that you record a still frame from the Alexa to SD card, load it into your computer, modify the stock Look from the Alexa, and then upload it to the camera. It's not as simple as it should be, and if I remember correctly, may require re-booting the camera at some point to up-load the modified look.
