Two Strange Problems (monitor resolution acting screwy, firewire problems)

the firewire ports in my dual gig powermac g4 (10.4.10) died randomly. so i put in a pci firewire card, which works fine...but now my monitor resolution resets to 1024x768 every time i restart. it does not remember that i use 1280x1024, and i have to change it every time i turn it on.
the other problem, ever since the firwire died: if i go to "system profiler" and click on "firewire," the system profiler instantly crashes.
i don't know why either of these things are happening, does anyone have any suggestions? thanks!

Ok
I've got a PCI combo fw + usb2 adapter on this G4 mdd 1,25. If I open system profiler and check FireWire nothing detected and sys prof crashes immediately, as yours. Fw works fine, Usb2 not very well, as I can deal with BlueTooth or Pen drive, memory sticks, but not ext hd LaCie 250Gb Usb boxed. After reading a lot I've find that chipset on PCI adapter(s) HAS to be NEC / OPTI branded for
good working on my Mac. The PCI combo card I'm using now has got ALI chipset, tried also another one VIA chip (worst)
If your FW port(s) dead for something wrong, it maybe necessary a PMU reset

Macbook pro and two HP 25xi monitors resolution issues

I have a Macbook Pro with Retina display purchased in 2014. I connected two HP Pavilion 25xi monitors and was having major issues where the second monitor would always be blurry and the resolution would not fit the screen so basically you could not see the border of the screen including the menu bar, sides, etc.
After troubleshooting and looking at blogs, I tried to investigate from the Monitor itself and did the following:
HP Monitor Menu > Image Control > Overscan > Turned it OFF
ISSUE RESOLVED!!!!

Top of the Line?
Meaning which one? I seem to recall reading somewhere it's got something to do with the RAM on the GPU???

Upgraded to Windows 10 and now I can't see my two HP w1907 monitors or change the screen resolution

I just upgraded my computer from Windows 7 Professional to Windows 10 Professional. Before the upgrade, I had two monitors. Since the upgrade completed, I no longer have two monitors. I need to figure out how to get two monitors back, as well as how to get the correct drivers for my two HP w1907 monitors installed, so that my system recognizes that I have two monitors. I also need to be able to reset the screen resolution to what I had before (in Windows 7).

Ipod update freeze, firewire problem, possible fix for many.

Hello all,
I've been having a problem with my ipod 3rd gen updating in much the same way as many in this forum have throughout a number of topic threads.
PROBLEM:
During song/playlist/content (not software update or restore) updating function one of two things would happen:
- update would freeze at some point of the transfer (5, 74, 687 songs in to the update) and I would have to force quite itunes and, not being able to dismount the ipod through recommended procedure, I would physically dismount the ipod and receive a scolding for improper dismounting of device.
- system would crash at some point of the transfer yielding the shaded screen and a prompt to restart the computer by depressing the front panel button for two seconds.
In each of the above cases, no matter how many songs that itunes thought it had transferred, I would only have about a dozen songs on the ipod itself, perhaps indicating a bottleneck on the G4 end of the transfer.
DEADENDS FOR ME THAT MAY STILL SOLVE PROBLEM FOR SOME:
- swaping out cables
- ipod software restore or restore to earlier version
SOLUTION:
After contacting Apple support, I was led to the opinion that the problem was with the firewire port itself. This was confirmed by attaching my ipod with my cable to a roomates G5 resulting in a faultless transfer of his song library. I was ready to go out and purchase a new firewire PCI card but decided to research firewire problems in the G4 folder of Discussions. This is where I found the fix to my problem (see links at bottom of document). It would seem that Mac ports, both firewire and USB, have a tendency to bog down after awhile and need to be reset. This can be a addressed by one of three possible solutions. The first and easiest was the solution that worked for me (for other solutions please follow links at bottom of page):
- powered down and disconnected all firewire and USB cables from the G4
- disconnected power cable from G4 (for laptops I would guess that the battery would need to be removed, not sure if that causes any other problems though, please research)and let sit for about 30 minutes.
- reconnected all cables and restarted computer. Ports should be reset at that point
- I took the added measure to restart my computer once with nothing attached to USB and firewire ports and then powering down with front panel button before connecting cables and proceding with final restart.
RESULT:
Faultless transfer of 37.6 gigs of content in less that 45 minutes.

Good Luck

This worked perfectly for me!!!
SOMEBODY PLEASE TAG THIS POST!!!
i have had the problem that everyone has posted about (i.e. - updated iTunes/iPod software and had the update/freeze problem, tried all solutions, to no avail, and was pretty much screwed.)
JUST DO EXACTLY WHAT HE SAYS TO DO (powermac g5, by the way):
1) power down the computer
2) unplug EVERYTHING (usb, firewire, power, monitor, etc.)
3) leave unplugged for 30 minutes
4) plug power back in
5) power up from main power button
6) wait for computer to start back up, then shut down from power button
7) plug everything back in and power up
8) restart once more for good measure
9) update your ipod
10) take a sigh of relief!
you are seriously a godsend...only one thing...I BOUGHT A NEW ONE ALREADY!!! i literally bought it the day that you posted this solution. After a month and a half of trying to fix this problem, i finally gave up and bought a 20GB iPod Photo with applecare...cost me about $380.
no matter, i think i'm gonna sell my "older" ipod to my mom or dad. they'll use it doing whatever they do. plus, that way, if there's any problem, i can fix it for them without feeling bad about screwing over some stranger.
thanks again, this solution worked perfectly.

Daisy chain two display port monitors (Dell U2913WM) to new Mac mini Thunderbolt?

Everything I read said that I could hook up a display port monitor to a Thunderbolt port on the mac mini. I purchased two display port monitors (Dell U2913WM) that can be daisy chained, and hooked them up. All I get is mirroring. Does anyone know how to turn off mirroring with this setup? I did not get the "uncheck mirroring" option in preferences until I hooked up the second via the HDMI port instead of a daisy chain. The problem with that is, I cannot take advantage of the full resolution through the HDMI. It seems I have wasted my money on two monitors.
Looking for advice on:
1) How to daisy chain these two Dell monitors to the mac mini and turn off mirroring and use an extended desktop, or
2) How to take advantage of the full resolution through HDMI port?
Any help would be greatly appreciated.
Thanks!

So re-reading this thread, I now realize you did exactly what I wanted to do but your issue was having a cloned vs. extended desktop. Oops!
I believe your "nothing plugged in" issue is the cable. I'm not sure that TB cables are backwards compatible with DP - I think it's only the ports. Do you see multiple monitors in "System Preferences > Displays" if you hook the monitors up like you described in your OP?
My Dell U2713H arrived today and it works like a charm with the supplied Mini-DP to DP cable. The built-in display on my 13" mid 2009 MBP still works if not in clamshell mode, although I will mostly use mine in my HengeDock. In the OSD of the monitor, you can access "Display Settings > Display Info" and it will show you the DP capability. Mine is only DP 1.1a and I believe to run 2 of these at full resolution you will need the bandwidth in DP 1.2 which includes MST (daisy-chaining). This could be your problem.
Can you access the same menu in your OSD and report back what your DP compatability is?
Thanks!

Can I run two big external monitors on my 2012 MacBook Pro?

I understand that my NON-retina 2012 MBP can be set up to drive two Apple Thunderbolt Displays, but am I out of luck on driving two generic 27" DVI or HDMI external monitors?
Boring details: I've just bought a mid-2012 MBP, with a quad-core i7 and 16 Gb of RAM plus the high-end GPU w/ 1GB of video RAM, but non-retina. I'd like to run two external 1080p or DVI HD-equivalent monitors (I have several new Samsung 27-inchers). I can live without the laptop 15-inch screen while I'm doing it!
I know that the retina MBP has two Thunderbolt ports, plus a DVI port, which would have easily given me what I need. However, I didn't get the retina MBP because it's totally non-upgradable by a user. There were a couple of other potential additional issues, including some reported problems installing Windows into Parallels via external DVD player. There's also the $mid-3000's price for retina, tricked out the way I'd like... Tradeoffs! At least I still have Firewire.
The two big externals help a lot with video editing. Even with my old G5 PowerMac, you could immediately drive two 1080p-equivalent displays. I expect that someone will release a much-more powerful solution than the Matrox USB 2 screen driver dongle, etc., sometime soon, using "superfast" USB 3, but I'll lose one of my two USB 3 ports; I'll want to have 'em both free for other externals, I'm sure.
Thoughts and/or solutions?

For those following this thread...
There is a posting elsewhere here in Discussions that describes how to get two large external monitors running on a recent Macbook Pro by using only ONE Apple Thunderbolt Display, then daisychaining a LaCie Thunderbolt drive after the T-Bolt display, and this allows adding another large DVI display in the chain after the LaCie.
Still pricey, since it does involve buying one Apple Thunderbolt Display, plus a LaCie drive, and cables, plus the DVI display, but it's around half a thousand dollars cheaper than two Apple T-Bolt displays, plus you have a very fast LaCie external drive.
Still not what I'm looking for, but if you're interested, here's a link...

10.4.7 update and external firewire problems with HD corrupion

Dear all,
Advised by Jpfresno I started this new topic about Tiger 10.4.7 update.
I will repeat my post and what was happening 2 weeks ago:
“In 5 years 10.4.7 update was a tragedy for my Powerbook Ti 667. When I update from 10.4.6 to 10.4.7 my 300 GB firewire drive gets corrupted, after repairing it with DiskWarrior and after connecting it to my PowerBook my computer freezes and I must shut it down via powerbutton. Safari also crashes after the update.
I just erase my Hard Drive and after that install 10.4 and update with combo to 10.4.7. But I had the same problems: finder freezes with connected firewire devices and also safari when browsing. I spend a week trying to solve the problem but no luck.
Yesterday and with no firewire devices, 10.4.7 freeze and I have big trouble in order to started my powerbook!!! Even when i insert the 10.4 install DVD it did not detected my HD. Finally I get it to work and install 10.4 and combo update to 10.4.6 and everything works. My external firewire drive and safari. I already diagnose my HD with disk utility, TechTool and directories with Diskwarrior and everything is ok.
I clone my 10.4.6 to firewire, boot from it and everything is working. I let my external drive connected and finder does not freeze.
My conclusion is that the problem is 10.4.7 update. It only give me problems and I was getting crazy with it. 10.4.6 is working good and I do not advice anyone to update to 10.4.7.”
Last week after reinstalling 10.4.6 I started to have HD problems with my Powerbook 667. I did a surface scan with TechTool I it reported bad sector. Then I done a zero disk format but after a second surface scan TechTool also reported bad sector. Then I take the decision to replace my internal HD. I bought a Samsung 40GB Hard Drive and installed it on my PowerBook. Then I have done a clean installation of 10.4.6 with all applications that I need and clone it to my hard drive with Intego Personal Backup software. Everything works on 10.4.6. and external firewire drive.
After that everything is ok. But I decided to test if my problem derivates from 10.4.7 update or from previous HD corruption. Then I install 10.4.7 update on my Internal Hard Drive. Everything is working good but after connecting my external Hard Drive the finder started to freeze!!!!!!!!!. After that I tried cloning HD to external firewire with Intego personal Backup. Everything was working good but when it was finishing the backup process started to give errors!! I started panic. I interrupted the backup process but after and after restart I found something strange with 10.4.7. The system started up, I login but I could not started any application!!!??? All my application died!
Then I have done one more clean installation of tiger and 10.4.6 update.
My conclusions are that the 10.4.7 update causes all the problems that I have on my PowerBook, because I used the same methods and same software/hardware on 10.4.6 and did no have any problem.
This last two weeks were very difficult to me. I tough that these problems do not happen with Apple computers but I was wrong!!! It is very hard to me to deal with it. I always said to my friends that I never had problems with Apple computers. I accept that a hard drive died because the use of it but I can not accept that a system update cause me 2 weeks of hard problems and make me loose precious work information! I always love apple computers and Apple OS but now I am disappointed
If anyone can explain what happen or have a solution for those problems?
Thanks for the comprehension and collaboration.
Best Regards
Mac OS X (10.4.6)

Hi, alsvieira.
There are some things you did not check in all of your troubleshooting:
1. Run the Apple Hardware Test (AHT) that came the affected computer. See my "Apple Hardware Test" FAQ for comprehensive advice on using the AHT in troubleshooting.
2. re: FireWire troubleshooting: Here is some general troubleshooting advice that may help if problems return with your FireWire drive:1. Review the AppleCare Knowledge Base document "What to do if your computer won't recognize a FireWire device".
2. If this problem occurred after installing a recent Mac OS X Update, and you are also unable to mount CDs, DVDs, or disk images perform the steps in this Mac OS X Hints article. This worked under Panther and may also work in certain situations under Tiger.
3. Power-on the FireWire drive before starting up (booting) your Mac.
4. Reset PRAM and NVRAM.
5. Resett the power-management chip in your Mac.
6. Try a different FireWire port. James Wiebe, CEO of WiebeTech, has published FireWire Port Failures in Host Computers and Peripheral Devices, a white paper providing backgroud information and technical analysis concerning the causes of failure for FireWire ports. This may provide additional diagnostic information.
7. Micromat TechTool Pro version 4 can test the FireWire bus in your computer: this tests the bus — not the ports — but if the problem is on the FireWire bus on the logic board, it should reveal it.
8. Check with the manufacturer of your FireWire drive or enclosure to see if any firware updates are available for such.
9. Hopefully, the partition map on the FireWire drive is not damaged. This can happen if the FireWire drive was not Ejected before being disconnected or powered off. If it still refuses to mount, you may need to employ data recovery tools or services: see my "Data Recovery" FAQ.Note that some of the information above is from the "FireWire Problems" chapter of my book, Troubleshooting Mac® OS X.

My Mac mini no longer detects my monitor resolution

My Mac Mini has stopped being able to detect the resolution of my monitor, which is a 1680x1050 Acer widescreen. 1680x1050 is also no longer a choice of resolutions under 'Displays' in 'System Preferences' so I cannot select my monitor resolution manually. I suspect that there is a bug somewhere in a recent update which has broken support for my monitor. Is there an official channel by which I can report this bug? Has it been reported already? Is there an ETA on a fix? This renders my Mac more or less unusable.
Here's some info about what I'm running:

Est. external monitor resolution

I am trying to set up a samsung syncmaster 191Tplus as an external monitor on my macbook from early 2008 running 10.6.8. When I plug it in, both screens flash (not just a flicker) as shown in this youtube video posted by someone else, but my problem is the same
http://www.youtube.com/watch?v=2-Yz-Em2GU4.
I am using the mini-DVI to VGA adaptor. The resolution of the samsung is 1280x1024, which is not listed in my choice of display resolutions. Is this the cause? What can I do? I can't access settings to change anything after the monitor is connected, and I can't find settings for the external monitor before it is connected. Would using SwitchResX work to create a monitor resolution preset before plugging in the second monitor?

OK, here is something to try. Go into System Preferences and select Displays. In the window that opens will be a checkbox for "Show displays in menu bar." Put a checkmark there and make it active. There should now be a little icon of an Apple display on the right side of the menu bar at the top of the screen. If you click on it, it will drop down and give you a short cut to different resolutions. There should be a checkmark next to the currently active resolution. Is it set to 1440 x 900? If not, set it there.
If you are still getting that message from the monitor, well, I don't think the Mac is lying about sending 1440 x 900. If the screen doesn't look right to you, try using the Auto Adjustment feature on your Viewsonic monitor. It could just be that the image needs adjusting.

Mac mini monitor resolution

Hello,
I bought my mac mini today ( 2.6GHz dual-core Intel Core i5 - Intel Iris Graphics - OS X Yosemite ) I connected using the DisplayPort DVI cable to my Viewsonic vx992 monitor. I have been using this monitor for my Windows XP which used to give me 1280x1024 resolution.
When I connect the new Mac to my screen is work but I with poor monitor resolution .. It's 1280x1024 but poor not clear
I'v been used this monitor with Windows with the same resolution and the monitor resolution was excellent with Windows.
I connected the Mac with Samsung Smart TV via HD cable .. The monitor resolution is excellent
This is the converter that I used:
http://www.amazon.com/gp/product/B007KB0EGC/ref=oh_aui_detailpage_o00_s00?ie=UTF 8&psc=1
Now, I'm conflict .. Is the problem with the convert that I'v been used or from the monitor ??

Hi IIIaass
I don't know if the screenshot will showing you the noise that I talk about ,, there is a little noise in the text for example .. I work for while on my monitor and I know the resolution quality and the clarity that should be,, and I don't want to buy new monitor then I discovered that the problem was from the Adapter.
Thanks again .. and please tell me what's the best HDMI converter to DVI if you know about it.

But I am getting this alert from SCOM and SCOM has no information about the alert for me to find out what to do - thought that was the point of SCOM to let you know of problems and how to resolve them. :)
The alert is coming from the Error Count Monitor that is part of the Hyper-V Management Pack Extensions (v 4.0.0.0)
I have tried looking in the Event Logs on the Host and there doesn't seem to be any storage related errors there. I am trying to establish if this is a false positive, why it is happening and if it is safe to override and ignore.
There is nothing on the Product Knowledge tab and nothing on the Alert Context other than what I have already mentioned (see below).
Thanks for responding.

Changing monitor resolution with proper aspect ratio

My project size is 800x600 and I wanted to provide an option to the user to change their monitor resolution at 800x600 by clicking on button. I have also planned to do it by using buddy api xtra, and already tested it. The problem is, when I am doing this on a PC with panoramic monitor (native resolution 1920x1080), it got stretched. I know it's very natural (as the aspect ratio has changed ) and I can get it in shape by squeeze the width using 'draw.rect'.
I noticed, there are some PCs with advanced display card that don't even get stretched, but shows the 800x600 resolution in proper aspect ratio by keeping the extra space black both sides. And I don't need to write any further codes (squeeze the width using 'draw.rect') to keep it in shape.
The real problem starts here, I can't able to filter the above situations by any logical means. I wanted to write codes only for the PCs that get stretched, but I didn't able to find any support from Director to determine which type of display card has been attached. I need to know whether it will get stretched, or the display card can able to manage the aspect ratio.
Any one have any solution in this matter?
Please don't hesitate to ask if you need any more info.

Hello handler
If you talking about this kind of thing...
https://forums.adobe.com/message/5773207
search for..... _movie.stage.drawRect = _system.deskTopRectList[1] & _movie.stage.rect = _system.deskTopRectList[1]
You don't need an xtra to change the resolutions - but you do have to work a few things - I tend to use flash text because it scales better.

Help to reset monitor resolution?

Greetings,
I have a G5 Quad with an Ati x1900 graphics card running into a 52" Samsung LCD. This was working fine through a dvi-vga adaptor until I switched the monitor resolution from 1920X1080 to 1360X768 which is not supported by the monitor .....blank screen. I plugged another 19" monitor into the other output on the card and both work fine but as soon as I remove the 19" the 52" reverts back to the unsupported mode.
I have reset the pram and tried booting in safe mode but that did not help me.
From bootup the 52" works fine until just before the login screen, then it switches resolution......blank screen.
Would anyone know where these settings would be housed in OS 10.5.1 so I can modify (delete) them?
Any ideas would be much appreciated
Thanks
Gareth

Thanks so much for your help.
Not wishing to play around in single user mode, I opted to delete the files /Library/Preferences/com.apple.windowserver.plist
/Users/username/Library/Preferences/ByHost/Preferences/com.apple.windowserver.xx xx.plist
using my PowerBook over the Firewire with the G5 in target disc mode.
This worked a treat
Thanks again

Is there a method in labviewto dynamically save and change the monitor resolution under program control?

Is there a method in labview to dynamically save and change the monitor resolution under program control? I have another application that runs on another monitor. I would like to change the monitor resoultion to 640x480 on program startup, and then restore the monitor resolution back to the user's settings on exit. Can this be done?

Have you already done this manually? I've seen Labview scale front panels very strangely when changing resolutions...

Firewire problem since upgraded to 10.4.3

Hi there,
since I have upgraded my iMac G5 to 10.4.3, it is no longer recognising my external Lacie firewire drives. These work fine as I have tried them on a machine running 10.4.1, and they worked fine on the iMac G5 before I upgraded to 10.4.3
The iMac powers the devices but they do not mount or show up in disk utility or apple system profiler...
any ideas?

Robert,
Take a look at this thread:
http://discussions.apple.com/thread.jspa?threadID=260074
Also, which update method did you use when you went to 10.4.3? Did you use Software Update or did you download the update from Apple's website? Some users have reported a resolution of Firewire problems by downloading and installing the 10.4.3 Combo Updater from Apple. You can do this even thought you are already at 10.4.3.
Regards,
Steve M.
