Finally received my Tobii yesterday and can confirm the 4C works with 16:10
However, I am running into the same issue thats been reported of the detection being above where I’m looking by about 2cm.
The odd thing is that in the 9 dot post calibration test screen I’m close to the centre of all the circles but not at the desktop and in games.
‘Look AT gaze’ and ‘aim AT gaze’ are technically more ‘Look NEAR gaze’ and ‘aim NEAR gaze’ – not quite what I was expecting from the 4C.
I also tried setting my screen to 1920×1080 1:1 16:9 and it made no difference.
