I believe it is a LOT brighter than my 7290.

during the day time it has a brighter screen, but at night the screen is darker than the 7290. I think the 8700c auto adjusts the screen brightness.

I have both in my hand now and its night...the 8700 wins on scree brightness hands down regardless of time of day or night, with or without the super bright mode on or off on either device.

it does auto adjust, but you can disable that feature and set the brightness yourself.

Plenty bright...more brightness is not required.

Nope I don't know you. I have never been to Seattle. A friend of mine went to school in Seattle. She's an interpreter too.

Hi, anyway to have the backlight off but keep the LCD display on like on the 7290? I liked daylight use without the backlight on the 7290, but it seems the display will only activate with some level of backlight--almost like it is NOT a transflective LCD that the 7290 has?

Nope...best you can do is "zero brightness", but that'll still keep your backilght on to a degree...

but its a totally different screen. you can't compare a 7290 and a 8700 screen.
Different technologies.

Colorwise the 8700 has way more colors and color richness (range of color at the pixel level).

In terms of brightness. I would believe the 8700 would be brighter based on the screen specs. From my experiences the 7290 just seems to get brighter because the backlight which is white gets brighter whiles the colors sort of fade.
For the 8700 it seems that the colors get brighter and richer as the brightness increases.

Yes, but the 7290 has a better screen when you want to look at it in bright sunlight with the backlight off! The 8700 has to have the backlight on at full tilt just to barely be visible! I much prefer the 7290 in this respect.

I am not experiencing any of the sort, in fact I owned a 7100g which would be blank looking in the sun, a Treo 650 which could sorta be visible but hard to view in the sun, while the 8700 looks bright and sharp in the sun, I was in the car yesterday commenting to the wife how impressed I was with the quality of display in direct sunlight.

YMMV

can you turn the backlight completely off on the 8700 and still see the screen in direct sunlight?

The 8700 REQUIRES the backlight to be on at any time in order to view the screen.

Yes, the brightness on the 8700 is great, and in direct sunlight it is quite visible, but it still has to have the backlight on!

the 7290 could have the backlight completely off and it would still look great! do you have a 7200 series bb? compare the two!

Do this test: Take the 7200 series bb and turn off it's backlight, then take the 8700c and turn off automatic backlight. Then turn the backlight to it's lowest settings thats "0" even though the backlight is clearly still on at the "0" setting. Finally take the two bb outside in direct sunlight: which bb has the brightest screen? I my test the 7200 has by far the brightest screen, even though it's backlight is completely off! The 8700c with it's backlight at "o" is barely visible in the direct sun, and I mostly get the glare reflection from the sun.

Look at the pictures I've taken:

The first is with the 7290 backlight off, screen on. And the 8700 auto backlight off, backlight set at "0" indoors.

The second is with the 7290 backlight off, screen on. and the 8700 auto backlight off, and backlight set to "0" outdoors.

Lastly the 7290 with it's backlight off and screen on, and the the 8700 auto backlight on (makes it brighter outside) and the backlight set to "100" outdoors.

Clearly you see the 7290 with the backlight off is superior to all the test done outdoors.

Thats because with the backlight off, the brighter the sun is the brighter the 7290's screen gets. If only they used this same technology with the 8700's screen... I like the added resolution, but the but it does not warrant the loss of this other feature! A feature which has been with the blackberries ever since they went color!

Yes, this is sad, but not a total loss. The 7290 has a "transflective" LCD that is like a mirror in direct sunlight without a backlight. Good for saving battery life, in fact I only used the backlight at night with my 7290 and rarely went below 60% battery charge. I think that the 8700 should have been able to maintain the transflective LCD since PDAs with high resolution like the DELL Axim X51v are a true VGA screen that can look awesome in sunlight with no backlight. What a shame. But, I still love it.

Thank you! finally someone around here admits the 7290 has a better screen than the 8700 in one respect! Not all respects mind you, just one. So yes the 8700 is still quite better. It just would have been even better if they had maintained this one little feature!

This is correct.

I can confirm the 72XX series (not 71XX though) does look better in direct sunlight than the 8700.

However, for non-direct sunlight, shadows, inside a car (while sunlight not shining directly), the 8700 at max brightness (two button presses on power button), does tend to look better when the brightness is maxed. It depends on how much light is hitting the screen, and how much reflections there are from the sky. The glossy plastic on the 8700 affects visiblity somewhat during outdoor usage especially if you're looking at the screen while in a shadow, but that blue sky is glaring off the screen. In this case, the 72XX sometimes is more readable (depending on how bright the outdoors is).

Nontheless, the 8700 is impressive among non-transflective screens (the 8700 appears to use a transmissive LCD, not a reflective LCD, not a translfective LCD). The best colors and image quality comes from transmissive-only LCD's, the same type of LCD's used in LCD monitors and televisions, where image quality is most important. The 8700 uses the same type of LCD technology. Fortunately, the backlight is bright enough to overcome most situations.

It is a tradeoff - I wish the screen was transflective, but the 8700 appears to have pretty good power management techniques that keep the battery last a long time, at least competitively to 72XX series for most typical usage.

The backlight will autoadjust to being fairly dim in darkness, which is the way I prefer it -- however you can force it to max brightness by hitting the power button two times, or by going to Options->Screen and setting backlight to 100%. That makes it very bright during total darkness, but a possible bother inside restaurants, movie theater, or next to your loved one in bed. But perfectly fine for outdoor use at night. But, in fact, I wish there the were dimmer brightness levels for an optional "discreet" mode of operation in settings such as movie theaters -- the minimum brightness of the 8700 LED backlight is still brighter than the EL (Indiglo type) backlight on an older 7230/7280.
