If I’m at my easel on one side of the room, and the monitor on the other side, nothing on screen would seem very big.
In the stores, though, those big screens do seem like they could swallow me up. I’m not much bigger than an action figure :)
I usually watch my 65” TV in a darkened room. I finally had to turn screen brightness down. It seems advertisers like white/brightness in their commercials. It’s as bad as the sound being ramped up when a commercial comes on, only it is visual. The blast of white light is almost painful and it tends to stay on throughout the break. Having the brightness at zero helps, but not completely.
