Quick Tip: How To Adjust Screen Brightness

Here I was feeling rather happy to have given a brand new Treo 650 to my brother for his birthday when upon first playing around with it he looks at me and asks “How do you adjust the brightness of the screen?”.

No problem I thought opening the ‘Prefs’ and looking for ‘Backlighting’ or ‘Screen’.  Thirty clicks and ten minutes later without finding either of these settings I was starting to get a little frustrated…

Evidently I had adjusted my own screen brightness before so it was just a question of finding where this particular function was hiding.  Considering that most other system settings are to be found under ‘Prefs’ I was more than somewhat puzzled.

Eventually a Treonaut friend put me out of my misery by reminding me of how to get to the ‘Adjust Brightness’ setting pictured above.  Namely, all I needed to do was press ‘Option’ + ‘P’ on the Treo keyboard.  Simple once you know what you’re looking for and it works both on the Treo 650 and Treo 700w.

I guess that some Treonauts may prefer to have their screen brightness set at 50% (below left) but personally I can’t use my Treo unless the brightness is at 90%+ (right).  Sure it may use a little more power but that’s why among others I was looking forward to the new Seidio 2400mAh Extended Battery (see More Power For Your Treo) – even if I’ve never had reason to complain about battery life before.


Hopefully now that I’ve written about how to adjust the screen brightness I’ll actually remember how to set it next time…

Treonauts always learn something new

You forgot the most important reason to dim the brightness: it can blind you at night.

Note the little sun icon on the P key.

I always dim my Treo screen before sleeping; even at the dimmest level it can still serve as a useful flashlight!

To temporarily dim the screen you can press the "option" key and the right-side shift/caps key.

Wow, I change my screen settings daily. I'm sure there's some app out there somewhere that will automatically calculate the sunrise/set in my area and make my sccreen bright during the day and dim at night, but that's a bit much if you ask me...

I didn't know about the temporary dim feature though, thanks for letting us know about it sven!

You have got to be kidding me...

Hey Andrew - it isn't April yet. We all know that YOU of all people knew how to adjust your screen's brightness.

Like the guys above me, I often adjust the screen brightness. ESPECIALLY at night, when looking at my Treo can be akin to staring into a super nova as I'm walking down the street. And yeah, I do occasionally use my Treo as a flashlight...

By the way, there's an app out there called 'BrightCam' which automatically adjusts the screen brightness based upon the light level of your surrounding environments as seen by the camera. It works pretty effectively, but I just prefer to manually adjust it as needed.

Already knew this, but what's with the following:
When I press and hold the Option button, after about 2 seconds a 'popup' appears with the title Not Set and a blank window underneath. Below theres a drop down with Minutes or Hours and a tickbox with S in front of it. Any idea what that is?

And the next tip would be:

- How do you type otherway than using on-screen keyboard?
- Keyboard you say? Never seen it here before.

Brutus. I think you Install a program called PROFILE, which behave like Nokia's profile (excellent freeware) program, if you want to set it up. press option button then Menu button it will direct you to its setting.

Profile program is a must in treo.

by BrutusNL | Mar 3, 2006 7:51:30 AM

@Mike: Wow, that's it. I even forgot that I had it. Once was going to try it, installed it and then forgot about it due to 'pressing matters'. Thanks to your reply I properly set the profiles, including triggers and never have to manually set the Treo to 'night-mode' ;-)

by Bubba | Jan 10, 2007 11:25:07 AM

Mike, do you have a link to the Freeware Profile program?

by euniceng. | Apr 16, 2009 11:45:29 PM

anyone know how to adjust the lighting in camera?
i tried the little "p" button with the sun, it doesnt work ?

by April | Jul 5, 2009 5:01:36 PM

I've been a treo user since it came out in the market...but Ive never adjusted the brightness. My 17 month old loves playing with the phone. Pressed all the buttons...and then voila THE SCREEN IS BLACK. I panicked (she's ruined 2 treos in the past). So I logged on and found this thread...THANK GOD. I didnt know it's that easy. Thank you!!

So much for brightness, how about contrast? The refurb 755p I just received from sprint has the colors all washed out and I can't find a way to restore them so it looks better.

by steve | Aug 6, 2011 3:51:24 PM

how can i adjust brightness. My "option" and/or "P" button are broken? How else can I access brightness. I think I sat on my phone and it went dark accidentally, I saw the adjustment bar on thescreen and didn't realize it was brightness.

How I can I access it another way? I can't readfd my pphone display anymore.
