Set default resolution

Hi, I have 6 headless xserves and need to set the default resolution to a different one, if I remember correctly it defaults to 800 x 600. anyone know how to do this? because there is no display attached i get a limited range of resolutions available.

I would like to add that this was happening to me but I didn't know it. When I synched clips (Canon 5D 1080P 23.98 with separate audio) and I double clicked the clip or cut it into a timeline, I noticed it was rendering (with the redish orange above the timeline). Could not figure out what it was rendering. Now I know. It was rendering the clip in the background to 720p.
When I change the resolution to 1080p like you say, it doesn't have to render anymore. I haven't figured out why it is doing this nor how to change the default. But I'll post if I figure it out.

Setting the default resolution for sap logon

Hi, ALL!
I'm terribly tired of SAP interface. It's so uncomfortable for work.
For example maybe you know khow to set the default resolution for sap logon to make it use its widgets of proper size. e.g. when i work with transfer rules, it has only half of screen for useful area (i use 1400x1050), and right part is just empty, but on the left very many small fields and you should constantly use scrollbars (i think you know it well). Maybe there is system customizing for this purpose.

Hello Dmitry,
There is no customizing for this - atleast to my knowledge.
However, you should have to redo the settings again and again unless you are continuously re-sizing the main window.

Default Resolution of new image

For other reasons I have to do a lot of preference-trashing, opening PS with Shft+Ctrl+Alt to delete the preferences file. What I am finding is that the default resolution of a new file is only 72 dpi.
WFound the place where screen and print resolutions are set. I have both set at 300 dpi. Still, when I create a new image the resolution is only 72.
Would you please show me where the default resolution of a new document is set.

File>New look for resolution and type in 300. As long as you don't select a preset, the 300 ppi will stick even if you close photoshop. This should be true for all versions, but I can only test in CS5.

Setting video resolution

Hi everybody.
I have an ipod touch 4th generation, 64 GB
I wanna know if it's possible to set video resolution of camera. If so, how I can do. If not, what's the default resolution?
Thank you in advance
Have a nice day

You can't change the video resolution. The resolution is 720P

Setting screen resolution in OpenBoot

I just got a new LCD KVM switch just will not support the default Screen Resolution in Openboot(1152x900?)
I entered this command
ok setenv output-device screen:r1024x768x60
output-device = screen:r1024x768x60
ok reset-all
But the setting just doesn't seem to register as the system stil boots up with the default resolution.
I'm using a Sun clone from Donovan with an UltraSPARC-IIi with Openboot version 3.14.0.
Am I doing anything wrong?

Well I tried the command on an Ultra60 Creator3D workstation and it seem to work just fine. I guess its the onboard graphics of the Donovan workstation thats giving me the problem. So it's a different issue.

OSX RDP v8.0.24308 Default Resolution/No Fullscreen for new connections

I would like to set defaults so that any new connection I create always are set to No Fullscreen, a specific Resolution, and a specif Color-Depth. I should not have to change this for all new connections.

Hi,
As far as I know, it does not have the Global Setting, we have to configure the settings separately for every connections.
Thanks for your understanding and I will forward your concern to the product team.

Non-default resolution problem

I understand that the default resolution for the MacBook is 1280 x 800. I find this hard to read (my eyes are rather old) and would like to set 1152 x 720 but this gets somewhat blurry, letters are not sharp, etc. like it is slightly out of focus. Is there any way to make a lower resolution look as sharp as the default?

This is the problem with LCD monitors. The way the pixels are set up on LCD's their is only one good resolution for it. Unfortunately the multi task people want more desktop room and so the resolutions have been going up. You can however go in and increase text size through Universal access in system preferences or if it's just Safari you want you can limit how small of font to render their too.
As far as resolution your stuck with the native resolution of the monitor unless you want a bit of the fuzziness that goes along with a different one.

Changing default resolution on XVR-100

For the life of me I cannot find out how to fix this.
I have a XVR-100 installed in a V440. I am unable to administer it via our KVM because the default resolution is way to high. When I change it, it of course screws up the screen and I have to reboot. fbconfig is not setting my desired resolution as the default.

That resolution is unsupported for me. How do I tell oenwindows to use 1024x768 with a 60hz refresh?
Thanks

From the provided information, I cannot tell whether you are using the HD15 or the DVI port. Furthermore, it is somewhat unusual to be using pfb1 unless you have more than one XVR-100 installed.
By default, the system will probably be looking at /dev/fb. Let's get the Sun to redo the video devices (this will trigger a reboot). Do this as root:
rm -rf /dev/fbs; rm /dev/fb*; touch /reconfigure; init 6
Do not try to use devfsadm for this step! Do the reboot!
When the system comes up, you should have a newly discovered video tree with your XVR-100 as the default video card pointed at by /dev/fb. If you have multiple video cards then you have more complex commands, but I am going to move forward assuming the simple case of one video card using HD15. If you are using a DVI connection or have more video cards, make appropriate changes to the following (PS: I do not read these boards often so you cannot count on me responding to a follow-up).
Let's set the video mode first. Do this as root:
eeprom output-device=screen:r1024x768x60
fbconfig -res VESA_STD_1024x768x60 try nowThe screen will get distorted, but as long as you get a screen, agree to take the setting and reboot the system. When the system returns, you should have the lower resolution. This probably does not solve your (implied) color problem, though.
To fix the color we need to change the configuration DT configuration. I am assuming that you have no configuration for DT. These steps may obliterate an existing configuration.
mkdir -p /etc/dt/config
cp /usr/dt/config/Xservers /etc/dt/configModify the last non-blank line in /etc/dt/config/Xservers by appending this to the end:
-dev /dev/fb defdepth 24The modified line would look something like this:
:0 Local local_uid@console root /usr/openwin/bin/Xsun :0 -nobanner -dev /dev/fb defdepth 24Reboot the system again and when it comes up, everything should be fine.

Default resolution for books enough?

Hello,
I haven't ordered a book in quite a while and in some older versions of iPhoto it was recommended to increase the default resolution (using a plist editor) before buying a book. Is that still a good idea in iPhoto 08?
Murray =:-)

Murray:
It's not necessary in iPhoto 08 because the preferences have been changed for the new version, setting the default at 300 dpi.
TIP: For insurance against the iPhoto database corruption that many users have experienced I recommend making a backup copy of the Library6.iPhoto database file and keep it current. If problems crop up where iPhoto suddenly can't see any photos or thinks there are no photos in the library, replacing the working Library6.iPhoto file with the backup will often get the library back. By keeping it current I mean backup after each import and/or any serious editing or work on books, slideshows, calendars, cards, etc. That insures that if a problem pops up and you do need to replace the database file, you'll retain all those efforts. It doesn't take long to make the backup and it's good insurance.
I've created an Automator workflow application (requires Tiger), iPhoto dB File Backup, that will copy the selected Library6.iPhoto file from your iPhoto Library folder to the Pictures folder, replacing any previous version of it. It's compatible with iPhoto 08 libraries and Leopard. iPhoto does not have to be closed to run the application, just idle. You can download it at Toad's Cellar. Be sure to read the Read Me pdf file.

but always GRUB2 run with 800x600.
Any ideas how to set 1400x900 in GRUB2? Is it even possible?

But as to why grub2 won't work, idk, I'm staying away from this over-engineered piece of... something... that just happens to also include a bootloader . Could be your syntax is wrong. Have you already tried 1440x900@24 or 1440x900-24 or simply 1440x900 or 0x037f?
Edit: Gah, GRUB_GFXMODE isn't for grub.cfg, it's for /etc/default/grub. If you're configuring grub.cfg directly, it's 'set gfxmode=1440x900x24'. See what I mean with over-engineered piece of something?

Change default resolutions provided by ML

Hi folks,
I'm having an issue at the office that kind of upset me. Basically, PC users laungh at Mac user not being able to display correctly on plasma's meeting room.
They have a native resolution of 1280x768 and this is basically what I want to use.
The problem is that this resolution is not proposed by the system in Monitors. Why is that ? My thought is that the TV is connected through VGA then YUV components cable, and that wouldn't surprised me the EDI informations does not make the way to the mac to announce supported resolutions, so the mac sees a "VGA Display" and proposes a set of default resolutions, this is what I'd like to adjust.
I was able to do this with SwitchResX but I can't ask every mac owner to buy a software to use an external display... those guys are gonna laugh harder !
The TV is a Pioneer pdp-505-cmx
Changing the connection to the screen is not an option, the cable passes from behind the wall to the floor and the meeting room table to a VGA connector.
Please answer if you really know what you're talking about and avoid "Open System Preferences and choose a resolution" !

Thanks... I don't know how that helps me tho !
I don't know hos windows is able to determine a correct resolution, but it can, and it works like a charm !
I still need to send the right resolution to the plasma, and rectangle shaped pixels in plasma monitor is not uncommon at all !
I should add that I tried every resolution provided by Mac OS X and none of them looks right (either pixelized, shaggy, wrong aspect ratio and so on...)
The only thing that worked is sending 1280x768 using SwitchResX. Even the aspect ratio looks good to me.
Here are the spec of the monitor :

How to set jpeg resolution when saving pdf file as jpeg

Hi
I am running a stand-alone version of Framemaket 10.I try to convert a documentation with a lot of screenshots in it. Regardless of the settings on the Reference pages of the first document of the book, Framemaker converts all graphic files to *.gif, and these are downsized so much that they become illegible. I would like to have them converted to JPG, with little resolution loss, so they are still readable.
I think Robohelp is too expensive…

Set Default Value of Multi-select list item

I have a multi-select list item I want to default the value of to '%' (which is really '%null%') and have it selected. I tried setting default value of item, but it doesn't take '%null%'. I also tried a computation with a static of
:P507_ITEM := '%null%'; How do you get the default value set and selected?

Hi
Shijesh is right, you need to change your null return value and use that return value as your default. Try and use something of the same datatype as your real return values if you plan to use '%' to display all as it will make your queries simpler. eg.
Company A returns 1
Company B return 2
% returns 0
Then your query would be...
SELECT ...
FROM ...
WHERE company_id = DECODE(:P_COMPANY,1,1,2,2,0,company_id)
Hope this makes sense.
Cheers

How can I set the resolution of my external display to 1280x800?

Hi, I'm using a Wacom Cintiq 12WX external pen tablet display with a 24" iMac.
The recommended resolution for this Cintiq is 1280x800. But when I go to System Preferences>Displays set the resolution of the display, the only available options for "Wacom Cintiq 12WX" are:
640x480
800x600
832x624
848x480
1024x768
1024x768 is my nearest option, but it has a different proportion than the display's physical shape--resulting in a slightly stretched display. Because I work with graphic design, this is not exactly desirable...
None of the other resolutions have the same proportion as 1280x800, so a stretch seems inevitable; not even working with a smaller resolution will give me the desired ratio.
So my question is, is there any way to choose resolutions other than those listed in the "Display tab" of System Preferences?
I also noticed that I have the option to rotate the tablet screen 90 degrees; when I do this, the option 800x1280 becomes available, but of course it's sideways...
Any help at all would be very greatly appreciated!

Thank you for your help.
I installed the update you suggested, but nothing has changed in my Cintiq 12WX Display menu in System Preferences.
Which update ?
The OSX update or the driver update or both ?
Might be neccessary to reinstall the Wacom driver after the OSX update.
And I concur with Kenichi, if all things fail contact the Wacom Support.
That thing has to work as advertised.
Good Luck

Cannot set display resolution after upgrading to Mavericks

I have early Mac Mini connected to KVM stitch. Over the weekend I upgraded to Mavericks and it "dowgraded" display resolution from 1920x1200 to 1600x1200 and everythign looks streached. 1920x1200 no longer shows on the list in display properties (1920x1440 shows but it does not look good on my screen). I googled Option key trick and hitting "Scaled" while hold Option key does show some additional resolutions, but not the one I used to have.
Connecting Mac directly to the monitor allowed me to set proper resolution and after removing monitor and pluging mac back into KVM things "held" untill Mac goes to sleep or until reboots.
I am aware that my KVM switch does not communicate EDID but things did work just fine before upgrade to Mavericks.

Hello curtdav,
It sounds like you are getting a graphical anomoly when unplugging an external monitor. I recommend these troubleshooting steps from the article named:
Apple computers: Troubleshooting issues with video on internal or external displays
http://support.apple.com/kb/ht1573
Reset the system
You can reset the Mac's parameter RAM and SMC.
Reset the resolution
Start by resetting the Mac's parameter RAM. If the display does not come up, was previously set to an unsupported resolution, and still results in no video:
Start up in Safe Mode.
From the Apple () menu, choose System Preferences.
Choose Displays from the View menu to open the preferences pane.
Select any resolution and refresh rate that your display supports.
Restart your computer.
Thank you for using Apple Support Communities.
Take care,
Sterling
