I had my cell phone screen replaced, did some tests and I saw that the hz of the screen fluctuates between 45 and 60, most of the time remaining at 45. It is really too annoying, it is possible to force 60 hz thanks to some app?

What are your observations, settings, and thoughts about tweaking CM6's light sensor levels?
(Settings > CyanogenMod settings > User interface > Automatic backlight > Edit other levels...)
Observations...
I've noticed that the sensor seems to only pick up light levels only at specific intervals (raw values, not filtered)... for me that was 160 (never went lower), 640, 1280, 2600, and 10240.
When it comes to lowest level the sensor reads it isn't really that low. I can be sitting at my lightly lit room or in complete darkness and 160 is the reading I get. Also, the highest level the sensor reads isn't really that high. I can be standing outside on an overcast day or in full sunlight and 10240 is what I get.
Thoughts...
Basically, given the observed intervals above, I have been trying to find a reasonable screen brightness at each level, where the screen is bright and doesn't appear washed out, but isn't unnecessarily bright either.
What is the lowest screen brightness that looks descent when the light sensor reads 160, 640, 1280, etc?
Where I'm at...
upto 160 - 35
upto 640 - 50
upto 1280 - 75
upto 2600 - 100
upto 10240 - 125
I really would like to tweak the higher levels, but I'm having a more difficult time finding lighting that is in those ranges. I also setup the power control widget to toggle the brightness between Auto>Dim>75%>100% to cover the lower light levels not picked up (below 160) and the higher levels not picked up (above 10240).
Observations? Settings? Thoughts?
Just wondering what settings (other than default) CM7 users are using for their automatic backlight. I've been experimenting for a couple days and have settled for this... for today at least.
Light sensor filter: Enabled
Window length: 20s
Reset threshold: 800 lux
Sample interval: 2s
Screen dim level: 10
Edit other levels...
Lower 0, 50, then 100-3000, increasing by 100's (32 total levels)
Screen 10-175, increasing roughly by 10's
Allow light decrease: Enabled
Decrease hysteresis: 80%
I'm looking to get a smooth(er) transition from each level. A fading appearance rather than a "hitting a light switch" appearance.

Also, here is a write up about what the settings do, just for your information

after I connected an external battery through multimeter instead of a built-in battery, I received such current values in different modes (values in mA):

browser idle 230-250

Sketcher, with totally white screen 650-700
1-2 mA in standby is very good! But as expected it uses quite a bit with the screen on and when we're actually using it. No surprise!
i see lot's of screen shots of the cyanogen brightness settings were the ligth sensor in at levels such as 30, and the screen level is configured to level 1 or 5.
mine, the sensor is always >200 and the screen level can't be lower than 35 (if i type 5, after clicking OK, it became 35)
is that normal? anyway to make the screen darker?
also, i assume the button light can't be changed right? because it does not change on mine at all.
Is this on CM7? There's a setting in there to set the lower limit, Screen Dim Level as far as I can remember. Its probably set to 35 hence you cannot set it any lower in levels. Set it to something lower like 1
Then go into "Edit Other Levels" and set your various levels in there. You can set the button setting to 0 for off, or 255 for on.
The Nexus One actually has 9 different levels for the light sensor, so you only need to set values for these.
10 - 160 - 225 - 320 - 640 - 1280 - 2600 - 5800 -8000
HTH.
PS this is one of the very useful options I really miss in ICS ROMS!

The ones posted before are far too dim at low light levels and are far too slow to adjust. The new ones work so well, I have removed my brightness widget.
The other settings have definitely given me the best battery life, however I wouldn't mind giving these a try for comparison. Do you have the lower (left column) values for the settings as well?
Are you using CM7 or CM9? Ive seen the same settings not work the same for both.
These are the settings I have been using for CM7. They work well for my 45 year-old eyes. As always YMMV

Buttons are 255 through 1st 8 levels (backlight ≤ 80)
Allow light decrease
Decrease hysteresis: 50%
The levels corresponding to the raw sensor output (10, 160, 225, 320, 640, 1280, 2600, 5800, and 8000) are all bumped up by 10 (15 for the 10) to force the lower light level. Extra levels help smooth the transitions.
If you find these to dim, bump the backlight levels below 120 up by 2 or 4. To bright, bump 'em down.
23 levels can be a PITA to set up, but it's worth it to me.
daj
Those look pretty good except for Window Length, dajmacd. If i set my phone under a lamp or walk by a window, I don't want to wait more than 5 secs for it to readjust.
Edit: OK, tried these. They work great. Thanks!
BTW, for those who don't know, the columns are reversed.
This is NOT Development
Thread Moved
The reset threshold overcomes the long window length when going from one extreme to the other. Oops on the reversed columns. I'll fix it when I get a chance.
Thanks for this detailed information.

Thanks for the information this was very helpful.
Thanks.
Thanks for the numbers. Always found the autobrightness to slow for my taste.
Yep, I use these settings....just a little bit altered to be brighter (since I live in the Arizona sun).
