Built in Contrast adjustment
I know there is a built in Contrast adjustment program in WM5. After doing some some registry tweak testing...basically me changing registry settings without any direction, I must have stumbled on something that activated a Contrast program icon.
When I ran it, there was a slider for screen contrast. I continued some more registry tweaks, but restored an old registry and lost the new Program Icon.
I don't know what registry setting it was that activated this, so if anyone knows how to activate it, please let us know!

Re: Built in Contrast adjustment
our screen driver (or maybe hardware) does not support contrast changing, so this is useless. Only backlight brightness can be changed.

I've discovered a registry key that seems to have _some_ control over not contrast, but gamma. You might be able to use it to get some results. Its located in HKLM/System/GDI/Gamma and it is a DWord called "Gamma Value"

There is no hardware contrast support on himalaya, blueangel and universal, only the
brightness control via PWM duty period.

I'm not sure if it works on other devices, but on a Wizard, you can go to HKLM\ControlPanel\Contrast and delete the redirect key (if there is one) and create a new dword value named Group with value 0 and it will put a Contrast icon in Settings that has an adjustable slider....

works...
registry tweak brings contrast setting to control panel but that does nothing (since contrasting is not supported)

Increase screen resolution on the MDA?

Hi
I've been reading over the forums for a bit now, checking up on how to increase the screen res of my MDA. I pulled down the ozVga app and ran that, but that didn't seem to work for me, it just made some of my fonts bigger, but the screen size stayed the same.
I also tried going into the Registry with Total Commander but I don't seem to have the HKLM\Drivers\Display\GWE folder where you can modify the LogicalPixels setting manually. I have a CxScreen and a CyScreen that had 240 and 320 as values. I tried updating those to 480 and 640, but after a soft reset nothing happened.
Any thoughts on how I can accomplish a higher screen res?
Model No: WIZA200
ROM Version 2.26.10.2 WWE
Thanks

You can't increase screen resolution, the physical size is 320x240. You can remove pixels and give the appearance of a larger screen at the expense of being able to read anything on it but it takes more than a couple of registry settings. A lot more. Check out http://nyditot.com/Home.asp which does what I described above. Last time I checked it sort of worked on a wizard but had a tendency to lock mine solid.

how to change the dpi of elf

hi you all ı want to change the dpi for making my elf screen high resolution have you any idea for this thank you

It's only one method. Buy all HTC Diamond parts, put them together and you'll have HTC Diamond, but you can call it Elf.

lol, nice answer gronostaj
what you are asking is to change the resolution on a static resolution phone. It can only operate at 320x240 nothing more. You can't magically enable 640x480 without actually changing hardware.

You can try this ...

Adjusting Contrast

Hi, I just bought a new set of HTC touch diamond, however as compared to the old one. The contrast of this new set seems really weird.
The black and dark tones are like grey even when i set the brightness of the screen to a much lower level. So i believe it is the contrast of this set that went wrong.
Is there anything I can do about it? or any problem that adjusts the contrast of the screen?
-Update-
After some google and meddling, I realised Windows Mobile actually came with this contrast applet that is hidden by phone manufacturers.
After some research I manage to make the contrast applet appear in the settings.
1) Using Registry Editor, rename Redirect to xRedirect in HKLM/Control Panel/contrast
2) If Redirect is unchange instead there is an added xRedirect. Delete the Redirect
3) Restart your HTC and Contrast should now appear
4) ???? However I am unable to change the contrast as the settings seems to be fix. ??
Does anyone know how i should continue from here? Do i have to modify the default in HKLM/Control Panel/contrast
Hope this prove to be useful for ppl who wish to adjust their contrast as well.
Hope someone can help me out. Thank you
Anyone know how i should continue from here? Do I have to modify

yes you can let the contrast cpl show, however that doesn't work on the diamond.
The contrast settings doesn't affect the screen
From what I have read in your post this isn't a software but an hardware fault
It would be wise to RMA the device.

Thank you for your Reply and clarifications.
So you mean the contrast problem is actually a screen problem?
Do you have any idea what would they do if I send my phone for RMA? Would they simply change the screen or change the entire phone for me?
Btw I live in Singapore. Heard they have really bad HTC care services in over here.

You're not alone... We are many people who want to find a way to increase the contrast on our Diamonds... It would really make our displays great if we could because it's a conrast issue, no doubt.
Been playing aroung with Resco Photo Viewer and slighty increasing the contrast when viewing photos makes them look awesome!!!
I'm afraid the default display contrast is hardcoded and cannot be changed by software but hopefully I'm wrong. Maybe it can be reached by some hidden menu???

yes, then we can go search for gold under the forgotten mountain...
it wont be hard-coded, it will be set by some software somewhere, just not apparent to the user.

I have actually got the contrast applet to show in my touch Diamond to show in the settings already. Refer to the first post on how to do it.
The problem now is even with the contrast setting show. I am unable to adjust the contrast sliding the control. It basically does no changes to the diamond..
and beyond that.. It is beyond my knowledge and expertise to do anything else. Thinking about RMAing my Diamond. But wondering how would they go about helping me? Change a new phone.. Doubt so..

Resolution aware

hi,
i have develope a application for years (from evc3 -> evc4 -> VS 2005). now i have to display a picture on the screen using alphablend. unfortunatelly, the alphablend funktion is not resolution aware. so i wanted to get the screen resolution to decide if i have to double the height and the width. i tried GetSystemMetrics(SM_CXSCREEN), but i got the wrong result. instead of 480 x 800 i got 240 x 400. is there an easy way to get the real screen resolution? i don't want to turn off the whole resolution aware feature and recalculate everything.

Yes - but overseen here.
Your Device has 192 DPI and the standard assumption of system is therefore wrong -because it isn' aware of the DPI.So you have to change your app to HIGH_RES_AWARE - here you go:
