Note the image in the gallery marked "They have the same function" - this is an indication that you can get one of two different models. And while they look very similar and essentially do the same job, they are NOT the same. I know this because I ordered two and got one of each. One of them has a switch to select a 30m or 50m ethernet route - and it really makes a difference. But it required zero tuning. The other model does not have this switch and has an "EDID" button that requires a direct connection to the monitor so that it can determine its settings. I think. I haven't been able to get this to work and the documentation that comes with it is minimal. I think I'll have to figure out how to return one of these and just hope it's the correct model when it's returned.
