I Play Significantly Better on My Chessnut Board Vs Screen

Sort:

I am not sure if this is common or why, but my rapid rating my chess.com account that I use for my Chessnut Air is 830 and the one that I use for playing on a screen is 780. No matter how many games I play, the board is also greater than the screen and at times the difference could be 150 ELO.

Any theories why? I know this also sounds odd, but I feel like the opponents I get for my board are not playing at their rating level, but the ones on my screen are much more challenging. I play the same time controls on both. Maybe I have better vision on a board?
