I'm not making it sound like anything. Trig it out. If you make some gross assumptions - your face is 5 feet from the screen (that would be a big room), your eyes are about 41" off the floor, and the center of the monitor is 30" off the floor you are in a position to look about 35 feet down the road. That is better than I guessed but by no means safe. At 20 mph you cover 35 ft in 1.2 seconds.
Still not safe, and that's conservative.
When you are racing you should be looking straight down the road. When you are training you should be doing the same thing.
Well, you can do the math, but I can assure you I can see well over 150 feet down the road with no change in head position from the one I'm using on the trainer right now with a low TV. Again, your eyeballs dip, not the head. It's actually very unnatural to ride for an hour with your head dipped down!
It's totally not a problem, just from experience. You'll see fine, and your neck will be plenty strong from being in the aero position during training.
Perceptually, the horizon as you see it (assuming level terrain) is at your eye level. So ideally you would have the centre of the monitor about 41 inches off the floor, if that was your eye height while in aero on the trainer.
Less is more.
