Has anyone ever constructed a viewing hood for using a LCD display (monitor) in daylight? I am thinking about a full hood that would be positioned over a screen and one would then peer into it. Sort of a truncated pyramid sort of thingy that could easily be removed and stowed. These sort of things used to be used on PPI radar scopes and on Oscilloscopes.
If you have done this and would be willing to share your knowledge, I would like to hear from you. I have searched with google and could only find sites that sold some partial hoods that do not interest me.

I did that for a Garmin Ique 3600. It has 2 openings on opposite sides of the top for the stylus and for a headphone jack. I located 2 brass rods of the appropriate diameter and made sure the smaller one was short enough not to short out the contacts in the jack. Then I drilled appropriate sized and placed holes in a piece of brass bar stock and soldered the rods in place. That bar was gorilla glued and screwed to a 1/2 x 3/4 inch stick of wood the width of the unit. Using the wooden piece as the main support, I made a hood from 1/4 inch plywood pieces gorilla glued together. A wooden support bar was placed between the sides and under the screen for further support. The bar was glued in place and also pinned in place with glue coated brass wire through the plywood sides and into the bar ends. 1/8 inch square and appropriately long glue blocks reinforce the plywood joints. A hardwood 3/8 inch square stick a few inches long with a hole drilled lengthwise is glued to one side of the hood to hold the stylus. The whole unit is painted flat black.

I have not built one, but I have seen them available for the purpose you describe. One possibility online is Captain Jacks. They provide laptop mounts, accessories, etc, that are quite good for boats.

Measure the circumference around case where you think a hood would mount. Then look for plastic milk jugs or juice jugs or chemical jugs with an eye for one that is close to the right size. Then cut the bottom out and the top off to make a hood. There is a lot of room for creativity here. If it is a slip fit try using it like that. Experiment with paint on the interior or exterior (flat black?) to improve light masking.
If you have to make it fit better, cut down one side (the bottom?), punch some holes and lace it on. Or overlap the edges and hold it on with a small bungee cord or rubber bands.
I used to work in rooms where the lighting was dimmed down in order to use one large, unhooded, not very bright display. And there were about 10 other adjacent smaller displays of various types.
Many of the other displays had to have the intensity either turned up, turned down, or lived with as they were if they did not have adjustable intensity. That gave rise to a non stop procession of ad hoc hoods to keep the too bright displays from bothering the dimmer displays and the eyes of the people operating the big display.
