It is no dimmer than the ST16 from Yuneec and there is not a lot in it compared to the Crystalsky from DJI. I did a specific test on this and it’s not dramatically diferent to the others.
The really is all of these screens need shade in bright daylight even the 1000 nits DJI CS.
It’s brighter than most mobile phones, and a shade is recommended.
To increase the brightness would be a total product redesign and an increase in price by at least 100%
There are many flying outside in very bright sunlight with this very successfully, are you sure you don’t have sunglasses on?
I update some my test with herelink waypoint
I have successfully used the Foxeer 2, and the GoPro 4 and video worked well. not many HDMI out cameras available, 
Currently working with this Caddx Turtle V2.

Hi,
?? how do you connect it to the air unit ?
Pascal
What do you mean? Connect what?
i do not understand how to connect the caddx turtle V2 to the air unit … there isn’t a hdmi connector .
Pascal, if the camera doesn’t have HDMI output you can not connect it to the Herelink without using an AV to HDMI converter.
Thats simply logic ! 
Best,
Julien
Hi. Thanks for good news. Does it has any note in setting or firmware?
i would like to understand why to use a av to hdmi connector with a hd system ??
That is a question for CaddX R&D team
The Caddx seem to be HD to write the file on the SD card, but have no HD output.
My bad I was looking at the wrong thing, we are using the Firefly 4K splitcam
Hello, good news for everyone. Now I can confirm that gopro 7 black can streaming through HDMI and recording at same time! Just tested it! Stock setting gopro!
Congrats!

The world real range test on one plane, it reached about 5 km out with horizontal antenna. At 5 km it’s a little bit signal remaining, i think it can fly further to 6 km.
great ! would you like to share your antenna set up ? and your next set up ?
Herelink fpv 8,6 km by fixed wing plane.
