Hi!
The HTC's Service Manual 1.1 Product Features part says: "the LCD is 262K, but limited via OS to 65K" . So is there a possibility that someone will "make" the Android shine in all it's beauty in full 262K ??
Is it a difficult modification/hack?
I don't think it's possible, given the OS is expecting to interact with the framebuffer in 16-bit. Not impossible, but just prohibitively difficult.

Seems to me its limited because Android is also designed to run on lower-end phones (dont wanna have to recompress to 65k for a different device)
Also willing to bet that the driver is only written to support 65k, (see above)
If someone wants to prove me wrong and hack it to work otherwise, I'd be happy to help
I've been looking for an explanation why the 320x320 resolution on these devices could not be enabled. Is there an insufficient RAM allocation? Does this device have VRAM? The 800W can do the higher resolution so where is the difference? If there is a better place to ask this then please redirect me and/or move this post.
I thought it had to do with the LCD screen, there are only so many pixels in the X and Y axis on the screen. All LCD screens have a native resolution. That is the highest resolution you can achieve with the screen. Anything higher than the native resolution will just zoom in.
Like on LCD flat screen tv, a 720p LCD tv converts the 1080p signal before it is displayed.
The screen only has 240x240 physical resolution. It's a hardware limitation, not software.

I don't think it's the LCD. I've seen techs put a 700W LCD on a broken 700P when doing repair so if it is a hardware problem, it ain't the LCD. Anyone else with a more authoritative reply?
Techincally, you can get 6.5 to run on a 240x240 device. The problem with the 700wx is the display driver. NightRaven and I have both made MANY attempts to get 6.5 to run on this device, but the video driver fails to initalize during gwes.exe initialization, therefor gwes.exe hangs and the boot stops. The last gwes.exe that will initialize the display was from build 207xx something. Unfortunately, 6.5 will not boot with such an old gwes.exe due to the many changes in it since.
We were able to get past that using a dummy ddi.dll driver, but of course no video. We were looking at attempting to recompile another driver for the 700wx device but haven't done it yet.

Noted. Everything I have read assumes the LCD hardware resolution is 240x240 but I have seen a tech replace a 700P LCD from a broken 700WX which leads me to believe they are the same 320x320 LCD.

I believe you are correct on that assumption. NightRaven believes that it was a driver limitation forcing it to 240x240 due to it being a WM5.0 device initially, which did not have 320x320 support. One of the things we are going to try when we get around to compiling a new driver is testing 320x320.

It's nice to get replies that reflect contemplation. I can't tell you how many forums insist the LCD is 240x240. I have conjectured that there may be a ROM call which sets memory allocation only sufficient for 240x240 operation. As far as I know, there is no VRAM or frame buffer RAM on the 700WX. If there is then the issue becomes considerably more complicated but if we can find the all the calls related to RAM allocated for display purposes, we should be able to unravel the mystery behind the video driver failure.
The displays on the 750, 700w(x) and the 700p are the same part numbers, so they would be the same resolution. Which is why I suspected the 700wx could support 320x320 with the right driver.
Once we get the necessary files for the pxa27x display driver sample, we should be able to create a new driver. We will attempt to create both 320x320 and 240x240 driver.
NightRaven
Awesome! I really appreciate the corroboration. Do you know if the WX uses VRAM or allocates system memory for its display? Is there anyway I can help? Do you know if Palm licensed Apple Quickdraw for the display engine? That might explain why writing a new driver is such a p.i.t.a.

Any news? I'll be checking in on this thread every month or so.
yeah this is a very interesting thread...
keeping an eye on it as well..
would love to up the res on my treo
Hello,
I'm desperately looking for a way to achieve an extended desktop on Android devices with TV-Out that almost resembles the extended desktop/dual screen experience known from traditional OS on laptops with an attached display.
In the end I want to be able to write Android programs that can decide whether a certain view shows on the mobile screen or on the second display, just like it is possible on the iPhone. This would allow apps to embrace both displays for unique interaction. Equally, by attaching a pico-projector, there can be private information handled on the display and public information on the projector.
What I know so far (please correct me on any false information):
There is analog TV-Out like on the Galaxy S, where mirroring the android screen to the attached display seems to be hardwired in the GPU, therefore not being an option.
Then we recently got HDMI-out on Android devices like on the LG Optimus Speed (2x), Samsung Galaxy S2 which mostly just mirror the mobile screen when attached to an HDMI display (except for HD video output).
And finally there are two devices from Motorola, the Atrix 4G with its Webtop application and the Droid X2 supporting Motorolas Dual Screen API.
The Atrix 4G uses a separate X11 server that knows of the mobile LCD Screen and the HDMI display (xorg.conf) and therefore can show two different desktops at the same time. Furthermore it shows a VNC-like view of the Android OS and its window manager. However, the environment is not Android anymore but embedded linux (Jaunty), therefore it would not be possible to write Android applications spawning multiple displays for this.
The Dual Screen API from Motorola supported on the Droid X2 allows exactly what I'm looking for, at least by means of OpenGL/EGL contexts. That's similar to what could be used as hidden API on iPhone prior to iOS 4 to enable an extended desktop (two separate views).
My Problem:
First the Droid X2 is not available in Europe (yet) and I already have an Optimus 2x and a Galaxy S2. I consider also buying a Motorola Atrix. All these have HDMI. Knowing all threads on hacking Webtop and HDMI mirroring, what would be the right way to go to achieve something similar to a Dual Screen API on other devices than the Droid X2?
Second, what would be the best way to integrate the second display with Android's Window Management that one could write something similar to
Code:
windowParams.output = WindowParams.HDMI;
updateWindowParams(window, windowParams);
Unfortunately, I don't have much knowledge about Android Window Management behind the scenes. I would be glad if anyone could shed some light on Android Window Management in the context of HDMI output.
ANY help or discussion GREATLY appreciated.

Is there really nobody out there with an answer to my first post on XDA-D?
I've found this https://groups.google.com/forum/#!topic/android-developers/Jxp_9ZtzL60
I have HTC Sensation and stock apps are able to do separate output. So there might be vendor specific apis...
Thx for your answer.
One of these APIs I learned recently about is the HDMI Dual Screen API by Motorola. Three of their Android devices already support it.

Hi,
I've found this code by decompiling htc video player in Sensation rom:
Code:
import android.os.IDisplayService;
import android.os.IDisplayService.Stub;
import android.os.ServiceManager;
.....
IDisplayService localIDisplayService;
try
{
localIDisplayService = IDisplayService.Stub.asInterface(ServiceManager.getService("display"));
boolean bool1 = localIDisplayService.IsHDMIConnected();
boolean bool2 = localIDisplayService.IsHDMIEnable();
...
But! android.os.IDisplayService does not exists in android api and i was not able to find any jar which contains it.
Hello,
I am looking for something similar but for tablets and I have been with the same problem.
Some progress in the solution?
Thanks!
Try the iDisplay app. Maybe it is what you are looking for. ...it does mirroring to your cpu.

Dual Display API Deprecated
The Motorola dual display API is no longer supported past Gingerbread. There doesn't appear to be anything to replace it.
I'm also interested in the development of this feature. I own a GT-N8010 and would love to use the s pen combined with presentation of slides. Did you have any progress in your search?
???
Any news on this subject?
Is extendind android desktop to tv via hdmi possible?
I have CM7 on my Tab. As such, I am on Gingerbread...
Any one can "hack" this so that it's made compatible with it?
Thanks in advance!
isnt it available on Market?
not compatible because :
Tablet requirements
Operating system: Android™ 3.1 or higher
Display size: 8.9-inch or larger
Display resolution: 1280 x 800 minimum
Camera: Recommended
source : http://www.adobe.com/products/photoshop-touch/tech-specs.html
It is available in the market but for Honeycomb only...
I know it's not supposed to be compatible (I read the requirements) but my question was wether it would be possible to adapt it...
and i thought you meant Photoshop Express! sorry my bad!
I installed 12.3inch(1920*720) Android multimedia on my car(ACCORD 10th)
and i installed other unfit resolution firmware on my Android.(I don't Know at that time,unfortunately)
then it is not working some fuction and shows cutted display
i want to back . but the Alliexpress Seller did not reply me.
I can't find firmware that has 1920*720 resolution.
somebody angel help me. please.
<device information>
APP : 1920*720 - 12.3inch
CPU : UIS 7862 Octa-core 1.8Ghz
MCU : 2021.04.27 YIN_53_L6315_G23P48F64_V1.0
If OEM hasn’t included a way to adjust the resolution by default, you at any time canl change your Android device's resolution settings by means of ADB.
Example:
Code:
adb devices
adb shell "wm size <WxH>"
