Just had a thought an hour ago. Tried it and it works for me.
Here I want to describe the method of my madness.
I practically live in a Lafuma folding recliner chair alongside my computer desk.
Have to, due to minor but chronic health problems. I can't sit in a chair.
Have my monitor on an Ergotron LX articulated arm.
If you want an easy life, ah, this is the setup!
Problem: All LCD monitors are optimized for your viewing from a vantage point of having your eyes on a level one or two inches above the top of the display.
That is, the vertical viewing angle is optimized for people who sit at desks (most of us).
Too bad then, if, like me, you must look
up at the monitor, or have your eyes, say
even with the center of the screen, pooh. You're not getting the best image.
For myself I just realized, I could make the display ever so much better for my special needs:
I've turned the entire
monitor upside down on its Ergotron mount.
The image is subsequently flipped 180, courtesty of the graphics card.
This new experience is very sweet. I still view with my eyes about on the centerline, of the screen,
but with the monitor upside down, the screen brightness and contrast over the range of vertical viewing angle is a lot more even than it was in
rightsideup mode.
That means too, for someone viewing my monitor from desk chair height: it looks awful now, nearly unviewable.
But not for me!
Now the monitor image is optimal when my eyes are an inch or two
below the level of the
bottom of the screen, instead of the other way around.
This new condition is ideal for me, laid back as I must be in the lounge chair.
BTW: Highly recommended for anyone is the Ergotron LX. It's cheap enough,
it's one of the best engineered, sturdiest products I've ever run across.
It's so easy to fit, to adjust, and then to use; the Ergotron is simply brilliant.
