Power Mac G5- Display Issue

PowerMac G5 running OS 10.5.8 with 20" cinema display.
Changed the inverter board in monitor due to one long, two short flashes. No more flashing light.
BUT...
Screen resolution is funky. Have res to highest setting and MOST things look fine except that when I am on the desktop the icons and fonts are too large, gey bar on top of desktop (along with text) is too big. Checked the settings for desktop icon size, Universal access, etc. etc and everything seems to be in order.
HOWEVER...
I dove in last night and reinstalled the OS. During the reinstall the grey bar on top iof desktop (along with text) is fine and the windows that open are of the right size.
I am dumbfounded...any ideas?

Mac Pro Display Issue

Mac Pro Display Issue - Unexpectedly Sleeps and Freezes
Just since a couple of days my Mac Pro desktop has been having display issues. Unexpectedly the screens go into sleep mode, it turns black and freezes, the computer doesnot respond to the keyboard or mouse.
At first I thought this was related to Chrome, and switched to Firefox, but the computer is still having the same issue. I have to shut down and restart each time it gets stuck.
I even went into preferences and changed the energy saver settings to "Never" allow display or harddrive to sleep. But this problem is stil happening.
Does anyone have the same problems? Or a solution?

I cleaned out my mac with compressed air, it was dusty, but the display flickering happened again.
So I followed your advice and installed:
Temperature Monitor
http://www.bresink.de/osx/TemperatureMonitor.html
Which showed that my memory module 1B and 2B were 70 - 75'C(160 -167'F). There was no reading for the graphic card so I couldn't tell if that was over heating.
Then I installed:
smc fan controller
http://www.macupdate.com/app/mac/23049/smcfancontrol
and increased the memory_cpu fan speed which lowered the temperature of the ram to 60'C (143'F).
I even changed this ram's placement and put it in different slots.This ram was the same temperature in the new placements.
Also this is the kingston 2gb ram without heatsinks. Ive used it for 1.5 yrs, and this is the first time its giving me these problems.
Do you know how I can check if the graphic card is over heating? or is the problem just with the ram?
Thank you for all your help!

Power Mac G4 Display Problem

I own a Power Mac G4 Digital Audio 733MHz model, and an Apple Flat Panel monitor.
The monitor connects using ADC. Sometimes when I boot my Power Mac the power light appears on the display, but the display screen does not turn on. Rebooting the Power Mac will make the display come back to life.
A while back someone in the Apple Forums suggested replacing the PRAM battery.
I tested the PRAM battery, and it is fine.
I opened up the Power Mac case, and see that the AGP card is properly seated.
What would most likely be the problem? Would it be the display, the video card, or the logic board?
Thanks!

Just an update, I tried a different LCD Display with a VGA connector and it works fine.
It must be the Apple Display.

Power Mac G5 boot issue

Hi all,
I'm having trouble's with my recently aquired Power Mac G5. It's the dual 2.7GHz liquid cooled model, 2GB DDR-400 (4x 512), 2x 160GB drives. It all originally started with a coolant leak which seems to be a pretty common occurance with these models, however I repaired this (which included replacing the power supply unit). The RAM, HDDs and PRAM battery are all brand new.
The unit will power up when you hit the power button (i.e, the fans rev up as normal, the hard drives spin up and you can hear the liquid cooling pump running) but the power LED doesn't stay on. It only illuminates when you actually press the button. There is no boot chime or anything displayed on the monitor. The fans eventually speed up to max speed and you can feel that the CPUs are generating heat. The unit will switch off if you hold down the power button for a few seconds.
The diagnostic LED next to the RAM only illuminates when you remove the air deflector (and HDD bay fan revs up accordingly) and there is no obvious visual damage to the unit. There is a red LED underneath the CPU & cooling unit however, but I haven't found any information about what this one is for.
Any information on this would be greatly appreciated! Thanks

Hi,
Just an update. I removed the front-panel board completely and started the machine by shorting the power button pins on the logic board. Unfortunately there was no difference to the start-up than mentioned originally so we can assume that the front-panel board is working OK.
While I was at it, I also tried a full PRAM/SMU reset by removing power and battery for 20 minutes, reinstalling the battery, pressing PRAM Reset, plugging back in and starting, but was also unsucessful

Power Mac and Display - power surge?

I hope someone can help even if it's common sense...
I had my Power Mac on for a while and all of a sudden a pop/click sounded and the power went off for the apple mac and the display/monitor.
Neither turned back on and there's no sign of power so I assumed the fuses need changing; however I replaced them and both the display and mac unit still will not turn on or show any power.
Does anyone have any suggestions what else could be wrong? Since it's affecting both display and unit, I can only assume it's power-related. Much appreciated, thanks.

Hi, and a Warm Welcome to Apple Discussions and the Power Mac G5 Forum!
Assuming the display is powered by the G5 video card and therefore by the G5 Power Supply Unit - and that you have taken the appropriate steps to ensure that the mains power up to the G5 is working ok - when the mains power to the G5 is first connected and turned on, there is usually a 'relay-click' sound at the back of the G5.
If you don't hear this, and you have a "Late 2005" dual-core G5
http://support.apple.com/specs/powermac/PowerMac_G5_Late2005.html
then it's possibly the 'Pop of Death' in the Power Supply Unit which would qualify under this recall, sorry, repair extension
http://www.apple.com/support/powermac/powersupply/repairextension/
If you do hear the relay-click, then you could try a PMU/SMU reset
http://docs.info.apple.com/article.html?artnum=300341
If still no go and you have another, earlier G5 which is not covered by the repair extension above, it sounds like a case for AppleCare, if you have it, or the repair shop. Sorry.
Please post again if you have any questions. Good Luck.

Mac Pro Display Issues

I am trying to use three monitors with a Mac Pro with a default Radeon 5770 graphics card, but I am coming across many issues. First, I had to find out that you needed two dual-link DVI adapters if you want to add three monitors. After purchasing one adapter from StarTech for a 30" Dell monitor however, the display is having many issues.
When I first turn the computer on, the display shows "snow". I have to turn the display on and off, but sometimes even this does not get rid of it. Also, the screen will not wake up when the computer wakes up from sleep, although the other DVI monitor attached works perfectly. Finally, the screen will often go into periods of complete black. I can still move the mouse on the other screen, but it jumps around and skips when I move it.
If I want to resolve this issue, should I:
1) Go with Apple's dual-link adapter instead of the StarTech one I am currently using
2) Upgrade the Mac Pro graphics to either the dual 5770 or the single 5870
3) Replace the large dell monitor with an Apple Cinema Display
Or, would none of these solutions even help if this is an unsolvable problem.
Any advice would be greatly appreciated.
Thanks!

That is not quite right. Strictly speaking, it is not three dual-Link adapters that are required, but all adapters must be ACTIVE, POWERED Adapters.
Apple's solution requires their Daul-Link adapters because those are the ones with a USB lead to pick up even more power.
Your initail query tlaks of wanting to connect three monitors, but you have only provided connection details for two.

Mac Pro Display Issue HELP!

Hello Everyone,
Lately i just bought a new mac pro. recently i have been doing some video projects in final cut pro 7 (i know its outdated lol) in the video preview it seems that the video has some distortion to it, meaning the the video has a skewed effect to it of some sort. I upgraded from a 2009 iMac which i have never noticed this issue before! I don't think that it would be a hardware issue.. heres my specs:
3.33GHz 6-core
12 gigs of ram
ATI radeon 5770 1gb ram
Monitor: Samsung SyncMaster SA300
I think that it may be the monitor.. as i soon plan on upgrading to a cinema display.
If anyone has and idea what may be causing this unusual issue that would be greatly appreciated!
Thanks in advance!

POWER MAC G3 FireWire Issue--Where to go?

I can't believe there's no place in the Discussions for blue and white Power Macintosh G3s. If you can talk about a 400MHz G4, I don't see why we're left out.
My issue: has anyone ever succesfully used Target Disk Mode with a PowerMac G3? I have tried it between two of them--never worked once; between G3 and G4, no dice. PowerBooks--nothing. Supposedly you can do TDM from OS 9 to OS X but I can't get two identical machines to see each other. I have 16 of them and it works on none of them None seem to need the FireWire updates either.

Hi, Toolshed -
Firewire TDM is pretty much independent of the OS. However, it is dependent on the hardware of the machine being able to support it.
All Macs which have built-in firewire are capable of being the Host machine in FwTDM. However, not all such are capable of being the Target machine - specifically, the B&W G3 and the G4 (PCI) models do not support being the Target machine. Probably not a coincidence, both of those models are also not capable of booting to firewire.
Thomas Bryant provided the link to the applicable KBase article fpr FwTDM in his post above.

Benq l23 6010 - Mac mini Display Issues

Im new to Mac.
I have a Benq l23 6010 which worked fine with my windows laptop .
But I tried it from my Mac mini (2012) display is not appearing well . Fonts text looks bad. Both are connected through HDMI cable. I have the default resolution in mac . I tried other resolutions also but the text looks bad and the icons doest look good.
Please do guide to solve this issue.

You are probably experiencing the white point bug. It is supposedly going to be fixed in 10.8.3, which I'm hoping we'll see by the end of this month and should see no later than sometime in March.
In the meanwhile, I find this "screen darkening" utility to be a good workaround for now. It's free in the Mac App Store:

Quicksilver Power Mac Spinning Wheel Issue

I have a Quicksilver P-Mac 867mhz tower that has 10.4.11 installed. 3 days ago it was running super slow and I had to relaunch the finder. It froze and when I rebooted the Mac it comes up to the Apple logo screen with the spinning wheel and that is it. Nothing else comes up even after sitting there for 20+ minutes. From the other posts, I thought maybe the batter was the issue, but I installed a new one today and that didn't fix it. I have reset the PRAM and have tried booting up in safe mode. No luck with either item. Could it be the power supply? This Mac has 2 internal harddrives, the original 60 gig and another 120 gig. I have had the system for 5+ years with no problems.
Any thoughts on this issue? I would think the hard drives should be good since I do not see the flashing ? icon come up during the boot process, but I also cannot insert a Tech Tool CD to reboot and try to repair either.
John

When I try to boot up the Mac, it gives the Apple logo and then the spinning wheel kicks in and just sits there. I can let it do this for 10+ minutes and nothing changes on the screen. So, my problem is that I cannot insert TTP CD into the optical drive because it will not open from the keyboard command.
This seems to be a big problem not being able to open the optical drive so that the Mac would boot off of TTP to try and fix the problem. Any other thoughts?
Thanks,
John

Mac Mini display issue

Hi
I have a Mac Mini 2008 model. I have upgraded the memory and hard drive last year but apart from thats it standard. I use a Samsung monitor with it. Recently the display has gone weird. Its like the brightness has gone crazy. Black is still clear but colours are very bright and whiteness is very white. Photos an video are very difficult to view. Its not the settings as i had not changed anything it just suddenly happended and I have checked it all and appears as should be. The fault was intermittent to start with as I checked all the cables etc, but now it is permeant. I changed monitors and put it on my big telly and it worked fine for a fews day and then went weird again. I was using a VGA cable so I thought I would get a new cable and went for a DVI cable as I heard they are better. But still no joy on either the monitor or my telly. So I'm now thinking it must be a hardware fault inside the mini. Any help would be greatly received.
Thanks John

That has done it! Thanks very much. I feel rather silly now!! Don't know how I managed to do that, must of unknowing pressed the right short cut keys. Thanks again.

Power outage caused display issue

we had a power outage that shut off the computer. After unplugging it until the power came back on; we found that when we turned the computer on the display just showed several 4" squares across the screen. The computer seems to have functionality still, but you can't read anything on the screen, it's as if the screen resolution is 7 blocks by 5 on the 20" screen.

New Mac Pro display issues with Thunderbolt display

When connected to a 27inch Thunderbolt display after a while I get vertical blue lines on the display. If I plug my Macbook Air into the screen, after a while the blue lines clear. How do I find out if it's the Mac Pro or the Display?

Thanks Turbostar, that's exactly right, it takes about 30 minutes having the Air plugged in and the stripes disappear.

New Mac mini display issues

My mom bought be a new Mac mini (new 2010 model) earlier today, and I've having a wee-bit of trouble. I'm hooked up via HDMI to my 32" HDTV and everything looks fuzzy--text on everything is rough, and pictures have low detail, so they look like paintings. I went to my display settings and put it on the highest setting (1360 x 768), but it didn't help. Is there another option I should try?

First, look in the TV's picture adjustment menus for a picture mode control. See if it's set to "vivid" or "dynamic" or something similar. Change that to standard, normal, or similar. This will tone down the TV doing all sorts of outlandish "enhancements" to the signal being input from the Mac.
Second, make sure that the sharpness adjustment isn't turned up significantly, as this will hurt the legibility of type on the screen. The lower the sharpness is set, the more readable the text will be. You'll have to strike a balance that you're happy with between text sharpness and a satisfying sharpness for the video content you watch. On my sony tv, I have the sharpness set at about 25%.

X240 + UltraDock+90W Power + 2 external display issues

Wondering if someone out there can help a newbie. Setup is a x240, Windows 7, Ultradock 90W, with two U2414 Dell monitors. Dual displays are working great, but ONLY if I keep the laptop lid up on the dock. I have tried adjusting the settings to "when I close the lid" to "do nothing", but still both the monitors go black when I close the lid. The setup I am aiming for is as follows.
1. When the lid is up, I want the internal display to be primary, with one Dell monitor being the extended display.
2. When the lid is down, I want the leftmost Dell display to be the primary, with the other Dell display being the extended display.
This was very easy with my older setup, but I cannot seem to get it to work with this new laptop and dock. Anyone have any ideas on how to resolve this?
