Which PDA ?
Hi,
I just did some testing with my iPAQ hx4705 and iPAQ 210 in bright morning sunlight. With the sun on the face of the PDA the backlight made no difference. The sun overpowers it and the display is pretty easy to read. Turning the backlight on and off made zero difference in the contrast or brightness. With the sun behind the PDA (me looking into the sun with the PDA screen in shadow) there was a big difference. With the backlight off I could hardly see either screen. With the backlight on I could see them both much better - but not great. So I recommend leaving the backlight on at full power while flying in gliders. The current draw is much higher but the readability is much, much better. For some reason the iPAQ 210 was a little easier to read than the hx4700. Probably because the hx4700's backlight is about 3 years old. Lights decrease in brightness with age/use. Another potential explanation is that I have a Boxwave screen glare reducer on my hx4700 and not on my iPAQ 210. I was very happy to see that HP made the screen of the 210 slightly textured so a glare reducer is not required. The iPAQ hx4700's screen is glassy so a glare reducer is needed. The glare reducer does slightly reduce the screen brightness. But the difference in brightness in sunlight was negligible.

My experience is that even if that works with the sun shining directly on the screen, it won't work when the sun is in front of the glider (not shining on the screen). I always have my backlight on full power. But I'll try turning it off today. I'm very curious. Paul Remde "noel.wade" wrote in message ...

Todd - Just a tip: I was surprised to find that if I disabled the backlight my hx4700 suddenly became easier to read in bright sunlight (but almost impossible to read in the shade or indoors). Not "easy", but easier. You might give it a try... Take care, --Noel |
