Can You Set Display Profiles on 2740p

[dstrauss]

On my 2730p the Intel driver let you set "schemes" which were user configurable display profiles so you could quickly switch to a desktop configuration. These do not exist in the driver for the 2740p.

Right now, I use my 2740p on my keyboard tray, setting profile with screen folded over the keyboard so I can write notes on it, while working on my HP 23" monitor on my other software (hint - have to make the built-in display the primary or it won't recognize the digitizer pen). Anyway, I have to reset all the settings (dual screen, monitor horizontal, notebook 270 degree rotate) by hand each time I dock the notebook start them up. The odd thing is it opens correctly with both screens in the correct orientation and resolution, only to revert to notebook only and I have to go through the display utility to reset everything.

I had the exact same problems when I upgraded my 2710p to Windows 7 x64.

Windows 7 has a built in feature the recognizes which displays you have connected and remembers the configuration for all different display setups you have used.

Then problem I had is exactly the same as you describe. When I docked my 2710p the display configuration would initially be correctly setup only to revert to the laptop display after a few seconds.

After lots of debugging I found out that the cause was the HP Quick Launch Buttons applications. Disabling the Quick Launch buttons would solve the display profile problems but it meant that I would also loose the auto rotation and stuff I decided to dig deeper into this issue.

I started replacing exe files in the HP Quick Launch Buttons install dir with a custom program I had written to log when each exe file was called and which arguments it was given.

This lead me to LCDRotate64.exe (if your on a 32bit install this would be LCDRotate.exe). I found out that when I docked my computer and in a few other situations this file would be called with the argument LCDCRT00 causing the Intel drivers to change the display configuration.

Since LCDRotate64.exe handles the display rotation I couldn't just disable it so instead I renamed it LCDRotate64-org.exe and added a new LCDRotate64.exe file that filters the arguments that gets passed to LCDRotate64-org.exe which solved the problem.

Whoa cowboy - you are way ahead of me on this one ("...I couldn't just disable it so instead I renamed it LCDRotate64-org.exe and added a new LCDRotate64.exe file that filters the arguments that gets passed to LCDRotate64-org.exe which solved the problem").

In essence, I will need to disable teh Quick Launch buttons, or have to take up programming? Why did Intel drop "schemes" from the display driver control panel in the first place...or did I just miss a feature? I guess I'll havfe to go the disable route because the coding is way beyond my capabilities.

Thanks for this tip. I disabled the Quick launch Buttons and now both my docked displays work flawlessly. However, as you pointed out, the down side is now I have to manually set the display orientation when is is not docked. Fortunately, this is fewer "clicks" than dealing with docking.

Unlogic, is your programming work-around something that others could use? I am also not a programmer, so if it would apply, it would be great if you could post and share it.

[Unlogic]

My workaround is very simple.

1. Go to the directory where you installed HP Quick Launch Buttons (often C:\Program Files (x86)\Hewlett-Packard\HP Quick Launch Buttons)
2. Rename LCDRotate64.exe to LCDRotate64-org.exe
3. Compile the following batch file to an exe file and name it LCDRotate64.exe

@echo off
cd C:\Program Files (x86)\Hewlett-Packard\HP Quick Launch Buttons
if not %1 == LCDCRT00 (LCDRotate64-org.exe %1) else (echo ignore)

Depending on your screen setup you may have to tweak the if statement in the batch file. But the file above works for me.

You can download a version of the batch file above converted to an exe file from my server here: http://pics.unlogic.se/27XXp/LCDRotate64.exe

Thanks for sharing your workaround. I downloaded your exe file and followed the steps without success. However, since I'm using 32bit Win 7, I realized it would need to be modified to work for me so I asked our office IT person to redo the exe referencing LCDRotate.exe. He did, but still no success.

When I dock, I see the correct display setup for a brief moment (as before) and then the display goes to "clone" mode and I still have to manually set the display settings.

Our tech asked me about the last line in your batch file and what parameters it was passing and I haven't a clue.

If it helps, here are the steps I go through manually each time I dock (My tablet sits to the right of my monitor in portrait mode):

Right click the screen and select "Graphic Properties"
Click "Multiple Displays"
From Drop down menu select "Extended Desktop"
Move the PC icon with the white Windows Logo from the left to the right, in-line with the left monitor icon

Click "General Settings"
From Drop down menu select:
"Display" - Built-in Display
Change resolution to - 1280 x 800
Select "Rotation"
Change rotation to - Rotate to 270 Degrees

Select "Display" - Monitor
Change resolution to - 1280 x 1024

Click "Apply" and "OK"

As you can see, it's lots of steps. Any assistance in helping with a Win7 32bit fix would be greatly appreciated.

Thanks.

Quick update - I received further clarification and questions from our office IT person this morning. He's helping me as a favor when time allows since I'm using my own tablet, which is non-standard, rather than a company issued laptop.

Here is what he said:

"I created the batch file to exe for the 32-bit system as follows:

@echo off
cd C:\Program Files\Hewlett-Packard\HP Quick Launch Buttons
if not %1 == LCDCRT00 (LCDRotate-org.exe %1) else (echo ignore)

It appears to be preventing the ‘change/change-back’ issue, but it is not setting the system to the docked profile. Do you think it is possible to resolve this with a different or additional parameters? What did you use to log what parameters were passed? As before this fix, the system appears to go to the correct layout before messing up."

Thanks.

If you want to log the parameters simple add the following line to your config:

echo %1 >> paramlog.txt

Now that I have a 2740p myself I've stumbled across the same problem as you guys mention in this thread.

It seems however that the problems with HP Quick Launch Buttons messing up the display configuration isn't as bad in the 2740p as it was on the 2710p.

On the 2710p I couldn't even lock/unlock the computer or resume from standby while docked without having the quick launch buttons mess up my display configuration.

On the 2740p it's seems that the problem only occurs if I cold boot or restart my computer while docked which I rarely do since I keep it in standby mode most of the time.

I tried to applied the fix from the 2710p by replacing the lcdrotate64.exe file with a custom executable file and even though this file is invoked it didn't fix the problem. It seems that the version of quick launch buttons used on the 2740p is a bit different compared to the one used on the 2710p and I'm taking particular interest in the qlbW7Disp.exe file.

I'm a bit short of time currently but I'll look into this later on.

BTW. those of you with 2760p tablets are you plagued with this problem too?

[Unlogic]

Edit: I've been using a version of HP Quick Launch buttons that came with Windows update, checking on HP's website however I notice that a newer version is available: 6.50.18.1 REV: A

The change log of that version mentions the following which seems quite interesting:

- Fixes an issue where an external monitor is disabled when the system resumes
from Sleep mode.

I'm on a business trip so I can't test this right now but I'll give it try when I'm back at the office tomorrow.
