Lion reduced the screen bit depth - any solution?
When I was on Snow Leopard I was painting in Photoshop in 16-bit mode on my 21" Wacom Cintiq.
It was a fantastic experience to finally have true control in settle changes in hues and shades all over the spectre.
Now that I've updated to Lion, the screen doesn't display true 16-bit graphics anymore, but instead there is pretty noticable banding. A sort of real-time downsampling in bit-depth going on. Even flickering on some grey hues.
I'm very sad about this, and it's affecting my work.
I have a hunch Lion is harder on old graphics cards than Snow Leopard was.
Is my machine too old for displaying true 16-bit/ 32-bit graphics with Lion?
In the system info under the graphics card it says: 32-bits color (ARGB8888), but it clearly isn't the case in terms of what is sent to the display.
MacBook Pro, late 2009, 8GB ram, 2,66 GHz Intel Core 2 Duo, Unibody
NVIDIA GeForce 9600M GT 256 MB
What I've tried so far (without solving the problem)
Closing Macbook screen to run only one display (Cintiq) (to save graphics memory, I thought) - no change.
Trieid displaying the same 16-bit image in different apps: Photoshop, Preview, Quicklook, Pages - no change
Forced monitor into "billions of colors" using SwitchResX - no real change
Anyone who knows more about this?
I will now try:
- finding Cintiq driver updates
I've tried to update the Cintiq driver, but in regards of bit depth, nothing changed.
My suspicion is that the graphics driver has to be updated/ optimized. And, judging from the overall performance dip my computer had after upgrading to Lion, it might be a big task, involving more than just the graphics driver. Perhaps the whole rendering engine?

(Mountain Lion) suddenly the screen turns black, and I have to use the on/off switch to turn it on. And, the screen turns to zoom, and the only way to return to normal is to close the window and start all over again?
Does the screen go black while you are using the machine? ...or after it has sat idle for a bit?
If it happens while you're using the machine, check to see if a hot corner has been set for sleep. You can do that here: System Preferences > Desktop & Screen Saver > Screen Saver and click the button labelled "Hot Corners..." in the lower right.
If it happens after a bit of idle time, that's normal sleep behavior. The delay can be adjusyed here: System Preferences > Energy Saver.
In either case, pressing any key on the keyboard should bring it out of sleep.
Re zooming -
If this happens while in Safari, and you are using an Apple Magic Mouse, a default setting applicable to it is that a soft double-tap on the mouse will zoom the Safari window. A second double-tap will bring it back.
If it is the entire screen that is zooming, Control plus scroll gesture on the mouse will zoom the whole screen. Repeat with the opposite scroll gesture to bring it back. -
How do you reduce the screen size in Safari Mavericks OS
Hit the ESC (ESCAPE) key to reduce the screen size in Safari Mavericks OS
Hi,
Reader can only be used to view pdf's so you cannot perform any operations on it.
If you have Acrobat then you can go to Acrobat > save as other > Reduced file pdf
You can also go to Acrobat> Save as other> Optimized pdf and then click on 'Audit Space Usage' button to know what is occupying how much space in the pdf and adjust accordingly.

Rental movie on i pad stops playing, then screen goes dark. any solution?
rental movie on i pad stops playing, then screen goes dark. any solution?
Quit the video app and restart. Go to the home screen first by tapping the home button. Quit the app by double tapping the home button and the task bar will appear with all of you recent/open apps displayed at the bottom. Tap and hold down on the video app icon until it begins to wiggle. Tap the minus sign in the upper left corner of the video app icon to close it. Restart the iPad. Restart the iPad by holding down on the sleep button until the red slider appears and then slide to shut off. To power up hold the sleep button until the Apple logo appears and let go of the button. Try the app again and see if the movie is there and will play.
If that didn't work - Search for the movie. From the home screen swipe to the right and the Spotlight Search feature will appear. Type the name of the movie in the field at the top, if the movie shows up in the search, tap on the icon and hopefully it will begin to play. Let it play for a few minutes then tap Done. Return to the video app and see if it is in there now.
If that doesn't help - reset the iPad - hold down on the sleep andhomee buttons at the same time for about 10 seconds until the Apple logo appears - ignore the red slider - let go of the buttons. Let the iPad restart and try the video again. -
cannot receive or send email from my hotmail account, refuses to verify server. I have changed my password, deleted the account numerous times, any solutions? all on ios 6. it was working up until a few days ago and now refuses to load on both my ipad 2 and iphone 4S
in the process deleted all my contact, very annoying.
all help is much appreciated.
interesting that my gmail account does work perfectly.this may or may not help - but give it a try. On a forum some were reporting that talk21 is now under the yahoo umbrella. below are the steps this use listed. (This was an android forum, but the email settings should be the same. In short it looks like their server names have changed. An existing account may have simply been forwarded - but if you are reinstalling, it may want a clean install to the right servers.) Pay particular attention to the server names and port settings. (this thread was started based on a discussion of Imap vs pop - you are already an Imap person - so ignore that part)
See if this helps.
why settle for pop3, when IMAP works with talk21 and not only does mail get pushed out faster with IMAP, but when you click refresh it will be received faster than pop3. The other advantage is subfolders are also supported with IMAP but cant be seen with POP3. This mail feature works with my android eclair & hero phone and the settings are exactly the same for win mobiles also (not tested). The mail setting up roadmap is the same from what i can remember once in the mail feature for win mobi.
This is what you need to do to setup Talk21 email with IMAP.
Incoming server settings
IMAP server - imap.mail.yahoo.com
Port - 143
Security type - none
Outgoing Server settings
SMTP server - smtp.mail.yahoo.com
Port - 25
Security type - none Also important note - Enable 'require sign-in'
and enter your talk21 username and password The End...works a treat for me p.s. Its only taken me 3 years to work it out with win mobile and recently with android. Finally got it to work...hope this helps all the talk21 users out there. if there are any other similar posts out there with no answer...dont forget to mention my name when passing this post around. -

Reduce the screen format in Mobile Data Entry
Hi,
How can I reduce the screen format for my mobile data entry.
I just have in standard 16X20 and 8X40
Can I create or choice another format? we need a smaller one because we can't read all the data on the scanner
Thanks
DedeWhat method of connecting the mobile terminals are you using (SAPConsole, WebConsole or ITSmobile), and which type of terminals (screen size)?
I had a similar problem using ITSmobile, but I found that you can adapt the templates so that the screens fit better. In some cases you also might need to customise the screens as well.

My touchscreen stopped responding to my finger and I can't unlock the screen...any idea how to remedy this problem?
Have you tried a soft-reset ? Press and hold both the sleep and home buttons for about 10 to 15 seconds (ignore the red slider if it appears), after which the Apple logo should appear - you won't lose any content, it's the iPad equivalent of a reboot.
