In Artemis there are only four levels for backlight. In Kaiser there are twice as many.
Is it possible to have eight levels also in Artemis?

Is there any way to increase LCD brightness?
I put a cheap Chinese replacement LCD from eBay in my Dash and it's not very bright. Its bright mode is only as bright as my SDA's half-brightness mode. I don't have a Dash with OEM LCD to compare, but I would assume it should be at least as bright as the SDA or my HTC PDA phones.
I know the backlight LEDs are most likely not as good quality as the HTC originals, but I thought I could brighten the screen by possibly sending a little more current to the LEDs. First thought was maybe I could just reduce the resistance of the series current dropping resistor to the LED backlight, but it appears to be controlled directly by an IC with no series current dropping resistor, probably using PWM. So perhaps there is some service menu program that will let me adjust the brightness? I looked at all the hidden .exe files in \Windows using Resco but didn't find anything.
Anyone?
I too would like to know!
umm there is no way to do so... sorry
Hello, I have an HTC desire and a Legend, the legend screen is a little more brighter than the desire, is an obvious difference when they are side by side, is this normal?
The photo does not show it well...
Assuming you've got both set to "Automatic Brightness", it's probably just minor differences on the brightness sensor. I'd imagine if you turned off auto brightness and set both to max brightness, they'd be about the same, though they are different screens and so could be different.
The real question is - is it a problem?
Regards,
Dave
No, I hope is not a problem, I hope it's normal the difference, I do not have another desire to compare to see if my desire is defective, or is normal.
And here in my location they sold out.
Try turning off auto-brightness and setting both to maximum brightness to see how much difference there is without the sensor complicating the issue.
That being said, they are different screens and since AMOLED screens are not backlit it is possible that the Legend screen just happens to be slightly brighter anyway.
Regards,
Dave
I have the same, the Desire screen is less bright than my Legend when both at at full brightness (and automatic brightness turned off).
Same issue here,both in auto brightness

I have a small problem with my BA. Somehow it started making some strange high frequency (buzzing) noise. Before last few days it was working very good with each ROM I installed. First I thouhgt that the source of mentioned noise is the speaker, but I was wrong. Source is in the bottom of device, somewhere beneath the screen, just above the mail button. Now, even when it just lies down on the table, screen flashes, and noise starts and some how turns off after 30, 40 seconds all by itself. Also, my battery life is reduced from two days to less than 1 day as a result of this issue. I dont know what shuld I do? Can anyone help me?
Specs please
How old is the device ?
Are there dark (or darker) spots at the edge(s) of the screen ?
Have you run the device at maximum lighting level ? - How long until the Backlight goes to powersave ? ... etc.
I assume - lacking further information - that the lighting is failing.
To my knowledge, there's a CCFL in the LCD I... that'll age over time and then show spots and flickering.
If you _can_ swap the CCFL you'll probable save your inverter ... CCFLs are relatively cheap elements (around USD 20 for 40cm which fits a 18.4" HD TFT Screen), though I have no idea how much a CCFL for the 9090 will amount to.
cf. to e.g. alibaba.com search for qtek 9090 lcd
eBay might help, too.
Good luck...

Hi, my english won't be very good because it's not my native langage.
I'm very sensitive to the flicker caused by PWM (Pulse Width modulation) wich is a technique used in the backlighting of a lot of LCD display to dim the brightness of the screen. I'm a "migraineur with aura" wich is a neurological disease, so like epileptic people my eyes and my brain are very sensitive to all sort of visual stress even the most subliminal one like PWM used at a high frequency. And I wanted to know if the note 10.1 (2014) use PWM to dim the screen at all level of brightness? I m' sure that it use it a least until 50 %, and that it is not PWMed at 100% brightness. Cause at 50% i'm sick litteraly within second, and at 100% i'm ok. But I have not tested all the level between 50 to 100 cause if it's flicker I can have quite a serious seazure, which would leave me ill for days, so it's quite hasardeous for my health. So what i'm doing is that i leave the system brightness to 100% wich of course is too bright, but I dim it with a soft (screen adjuster) that can dim the display without touching the backlight. But it's not a perfect solution cause the display is still using a lot of energy that way and there's a lot amount of blue wavelenght coming from it and i'm sensitive to blue wavelenght too. Basically as you can see, LED backligh is not a very good technology for epileptic people, eye-sensitive or migraineur. (I personally think it's not a healthy tec for anybody)
So, I just wanted to know if someone know if there's an "official" level where the note doesn't use PWM anymore to control the brightness of the screen, I mean below 100? Thanks in advance, and i'm sorry if my post can sound a bit confuse, it's not easy to try to ask and explain something in a langage that's note your native langage. Thanks in advance.
Maybe an odd question for XDA, but a question I need answered before I pull the trigger on this phone. Earlier this year while buying a new television set, I learned that I am amongst a small minority of people who are sensitive to LED-lit electronic displays that use pulse width modulation to control brightness. Apparently, I can look at a PWM CCFL-backlit (i.e. my 5-year-old computer monitor or my Nexus 5) screen or a DCM LED-backlit screen (my television set) for hours with no issue whatsoever but I can only focus on a PWM LED-lit screen briefly before I start experiencing symptoms of eyestrain and motion sickness. It's like looking at a CRT that flickers because the refresh rate is set too low. Now I know an AMOLED lacks a backlight layer, but it still has to adjust for brightness, so if it uses PWM to do so, then I have to presume it will cause the subtle flicker leading to the same problems that I've experienced with LED-LCD displays. Is there anyone here who could possibly shed some light (no pun intended) on this issue?
Yes, it uses PWM. My suggestion is to buy the phone, and if it bothers you, utilize the return window where you will receive a full refund.
