External Benq GL2460 Display Issues

Hello,
I have the Benq connected via Thunderbolt - HDMI, and here are some very irritating issues I experience:
Audio: When waking the computer up from sleep, it turns the default audio device output to the BenQ monitor. Which i only have muted from the display anyway.
Sleep: When i put my imac to sleep, the BenQ monitor starts to flash blue saying "no input detected" is there anyway to stop it doing this?

Tmodrich,
I see no reason why the external display has any bearing on the USB port functionality once the machine wakes up. The fact that you can use the keyboard to wake the machine, certainly tells me that the machine has some level of communication with the device.
Curious, do you own a USB mouse or have access to another keyboard (preferably an Apple one)? With that being said, do you own iPod or iPhone? I'm curious if you have that plugged into the machine and go to wake it does the charging functionality of the device get interrupted (after the machine is awake)?
You can also try resetting the SMC, that may (or may not) resolve the issue. But really the next step(s) that I can think of would be to try different peripherals or another type and see if the issue is replicated.

Macbook Pro 15 inch resolution on external 16:9 display issues

I just bought a Macbook Pro 15inch non-Retina display. I'm trying to connect it to an older Dell monitor I had that is 1600 by 900 resolution. I am trying to mirror the display but don't get a 1600 by 900 resolition when I look at my Macbook Pro display settings. I have a VGA connected to my monitor and macbook using the vga to mini display port. How do I get 1600 by 900 resolution? Do I need a bigger monitor?

External Apple 17" Display issues

I have an Apple 17" Display connected to my Powerbook 1.5Ghz but I no brightness slider shows up in the displays preferences with OsX 10.4.11. Therefore I can't adjust the brightness via software, or the button on the 17".
Also the Powerbook 'appears' to have a slightly magenta tinge to the whites, which I am now used to, but the Apple 17" Display has a slightly yellow tinge to it. I have tried many many 'by eye' calibrations with the Apple's software display calibrator but I cannot get the two to have a similar colour white point.
I'm not going for pro-level calibration, I just want the displays to have a similar color white point.

Good info.
That model monitor has only ADC connectivity. You must be using some form of adaptor? If so, can you provide its details? Does it use the DVI or the s-video ports?
I'm not an expert on ADC but I know it carried video, power, and USB lines concurrently. If your adaptor is not fully emulating the ADC connector functions on an Apple desktop machine with ADC, it could prevent the computer from properly identifying the monitor and offering you the proper options.
Apple recommends this adaptor:
http://store.apple.com/us/product/M8661LL/B?fnode=MTY1NDA5OQ&mco=MjE0NTg4NA
Note it has an extra line and brings its own power supply to the party.
I hope someone with more ADC experience that I can suggest what adaptors work best in your situation, Lacking that, you may have to look for another monitor that does not rely on ADC.

MacBook Pro 13" Early 2011 - External display issues

I have an early 2011 MacBook Pro 13" (2.7GHz version) that I am using with an external non-Apple display. I am having issues when MBP goes to sleep or trys to sleep the display. The external display exibits one of a number of problems: goes dark but does not power off the backlight or freezes up and requires being powered off then back on. My display is an ASUS VW266H but it seems like this problem, or other similar problems, are happening with other non-Apple displays.
In calling Apple tech support of 5/27/11 they indicated that this is a known bug and they are working on a fix. There was software update released 5/4/11 to "improve graphics stability, address issues with external display" named MacBook Pro Software Update 1.4 (http://support.apple.com/kb/DL1382). I downloaded this and applied it but it made no difference.
I experienced these problems with three different video adapters: Apple's own mini DP to DVI, Belkin mini DP to HDMI and another brand of mini DP to HDMI also sold by the Apple store.
So the questions are:
1) Will Apple release another updated to address this incompatability or are they done with the issue given that they released the update mentioned above?
2) Has anyone compiled a list of monitors that are know to work with these most recent MacBook Pros (the early 2011 versions with the Thunderbolt/mini DP combined ports)?
If you have used the MacBook Pro 13" early 2011 with an external monitor please respond to this post with your experiences so we can all know what works.

With my new 2011 13" MBP I'm having no latency issues using my '08 Samsung SyncMaster 2253BW DVI (digital) monitor. Sleep function awakens fine, goes to sleep 3-4 sec.
I'm using a cheapie model Syba MDP to DVI connector; here on Amazon:
http://www.amazon.com/Syba-High-Quality-DisplayPort-Adapter/dp/B00342UT02/ref=sr _1_1?ie=UTF8&s=electronics&qid=1307389450&sr=8-1
I bought 2 in case one craps out on me...knock on wood. Good luck hope you find a solution.

Pixelated enlarged screen - display issues related to external hard drive

Hi. I had an external hard drive plugged into my macbook. I have a second monitor hooked up. My screen is pixelated and enlarged (I have to scroll to see the whole desktop). The icons are rearranged and very blurry. Everything is blurry and enlarged. My files will open, but they are all blurry as well. When I noticed these display issues, I realized the mac was not detecting the hard drive that was plugged into the usb port. I unplugged it and then a LOT of folders with the hard drive name appeared on the desktop and then disappeared. I know I may have misstepped by unplugging it, but what can I do now? I have rebooted, shut down, checked zoom and screen resolution settings, and unplugged the monitor. It's the same when I uplug the second monitor and just view my desktop on the mac. Any ideas? Thank you in advance!

There is a multitude of posts here addressing the dangers of using Mackeeper. But just look at this:
https://discussions.apple.com/docs/DOC-3691
While this particular problem may not have been caused by Mackeeper, I urge you to uninstall this piece of trash.

10.5.6 Update USELESS!!! External Display Issues Still remain!

The external display issues remain, even after installing the update.
I'm sick of this!
Is it a hardware issue or software related?
Are the 9600 graphics chips defective?
Come on Apple and be honest to your customers, we all paid a lot of money for these systems!
Does anyone out there know where can I complain to?
I need an email address or something that is not directed at iphones or ipods!
Cheers.

I'm not sure what to make of this at this point. I ordered a CTO 2.8GHz with 4GB RAM and 320GB HD the day they were announced. First week or so, few if any problems. Then the "UHF" like bands of static began to appear randomly. I use my computer 90% of the time driving an external monitor. I use a separate set up at home and work with duplicates of all cables. The problem occurs on both. I spoke with Apple Care - they patched me over to support and moved me up to Tier one pretty quick, even had me send in my System Profiler information for every combination of screen and graphics card. Then they emailed me a program to capture my monitor info again with every combination of screen and graphics card. No solution. They finally asked to "capture" my computer for their labs and sent me a new one.
Once again, about 2 1/2 weeks of smooth sailing and bam, same issues now occurring. If it's a driver issue, why is everything fine for so long? Also, 10.5.6 and the new firmware have failed to address. Given my above exchanges with Apple, they certainly can't claim they don't know about it.
I've been using Apple Products for a long time. I've seen some real buggy stuff - like when File Vault first came out but this is the worst I've experienced. Seems like poor quality control. If it's a select few machines, I appear to have won the lottery as I've had two of them.
I'm sure this issue is much more wide spread as it is a non-issue if you only use the internal display. Only people consistently driving an external display will even know there is a problem.

Display issue on brand new 2014 X1 Carbon Touch

So I was about to start raving about my X1C that I just received. Loving the display, the keyboard, build quality, etc. I had no gripes and was just browsing away when suddenly the screen did the full glitch. I recognize this as what happens when something's messed with the motherboard/display adapter. So I gave it a reset. All was normal and then it happened again. I was able to replicate it 3-4 times and it keeps happening. I never dropped it or anything. It was always just stationary.
I can't believe this. I had problems with the first gen non-touch and touch. I was hoping by now they have improved.

Repeated iMac Problems, Display Issues now Kernel Panics

I’m lost on what’s wrong with my 2008 iMac and I think I just have to bring it back into Apple for a third time to have it repaired. But something is obviously not working that is causing these issues.
About a month ago, my computer began showing heavy pixilation, flickering images and the on-screen graphics. The computer appeared to keep working in the background from what I could tell so I came to conclusion that it must be the graphics card that’s failing and I’ll need to have it looked at.
My 2008 iMac was custom-built by Apple with the Nvidia GeForce 8800GS that was offered as an upgrade option. There have been several posts on the display and graphics discussion board about that graphics card along with other postings other places about the problems the Nvidia GeForce 8-series had.
The display problems I mention above would not happen immediately, it would happen as the computer warmed up and was used for 3-5 minutes.
Anyway I brought my computer into Apple explained to them what I believed was the problem and the Apple Store technician agreed with me. Because I did not purchase AppleCare, it cost me $400 and a week without my iMac to have that card replaced.
I got the computer back two weeks ago and everything seemed fine. It was working as it always had. I even was running SMC Fan Control in order to keep the computer as cool as I could (the Nvidia problem was related to overheating).
But this morning, this is what I woke up to:
http://img97.imageshack.us/img97/7436/photoijr.jpg
The computer now has a semi-permanent pixilation when it starts up (as suppose to the pixilation 3-5 minutes into use). But more worrisome now is I cannot start up the computer without it going into a kernel panic. I tried resetting the PRAM, I tried starting in safe mode. The only thing I haven’t tried yet is booting from an external HD which I will try this evening (to hopefully isolate it if it’s hardware or a software problem).
The Apple Hardware Test has been unhelpful. When it originally failed three weeks ago, the test showed nothing and this morning when I ran it (permanent pixilation and all), it showed nothing. I feel like if it was a software issue the pixilation would have disappeared during the hardware test because that’s not an OS-X based program.
Here are my specs on this computer:
2008 iMac 24" 2.8ghz Intel Core Duo, 4 gigs of RAM (Crucial Purchased, I have original sticks somewhere), 1 TB HD, Nvidia GeForce 8800GS.

Hi, just to update you, I came home today and did a few things that didn't seem to solve my Mac's problems:
- I booted up from my firewire "safe" drive that I keep a copy os x on to see if I had a corrupted hard drive or something. It booted into the kernel panic I described above.
- I also swapped out the crucial RAM for Apple's factory RAM. It also booted into the Kernel Panic.
In both incidents, the display issues didn't go away. Now instead of pixelization i have vertical bars running in a pattern across my screen.
I'm currently trying to boot onto the OS X CD at this point to see if I could do a reinstall. It's taking quite awhile to boot into that.
With that in mind, I think we're still having graphics card issues or more seriously some logic board problem.

External hard drive displays error code 22

My Seagate GoFlex external hard drive displays code 22 when I try to initialize it to active status...what is code 22 ?

You should really contact the vendor about this. Try the Seagate Forum. This is not a ConfigMgr issue.

13" Macbook (black), Snow Leopard, Boot Camp, Windows 7 display issue

OK I don't know where to post this. I couldn't find an appropriate forum under Boot Camp (nothing for display). Apologies if this is the wrong forum.
I am attempting to run Windows 7 using Boot Camp. Here is the behavior:
Booting Windows 7 without any monitor plugged in works fine.
Booting with an external monitor plugged in, I get the display on the external monitor. Now when I unplug the external monitor, the LCD display backlight is off and is completely dim. I had to reboot it in order for the LCD display to work again.
This is not a macbook display issue. But it has to do something with the way Windows 7, BootCamp are compatible with a macbook. Anyone seen this or know what the fix is?
Thanks
Sri

I can not get my Win 7 (32) os to see my Mac 10.6 partition. Is there something I need to set or turn on to get this to work?
As for your problem, perhaps Windows is not seeing the FireWire bus?

Display issues on mid 2009 Macbook Pro

I have had a recent intermittent display issue on my Macbook pro. It started a few months ago and is not a constant issue. External displays are fine so it seems to point to a connection between grahpics card and the 13" screen.
You can see an image of the problem here:
Does anyone have experience of similar issues?

i've done a complete rebuild back to 10.6.8 and found that both problems appear to have disappeared, both screen and TV working again since this morning without seeing any issues.
I'm now installing Lion to see if it returns.
the only difference will be that I'm not going to install bootcamp until later, this will be a clean install as before I installed Lion on a previous version of 10.6.8 with bootcamp etc already installed.
maybe this will work, wish me luck

Macbook Pro Early 2011 Display issue

Hi all,
After reading the replacement program that has been extended to MBP for 15" and 17", is there going to be any news with regards to the 13"?
The reason why I'm asking is that while I'm not sure if mine is an isolated issue or widespread/common occurrence, I have had my logic board replaced last year due to a display issue, and currently still unable to run external display, despite reading up on discussion that is going on.
The symptoms mirror that of the 15"/17", just that the 13" does not have a dedicated GPU.
Hope to get more suggestions/ solutions/ news to potential replacement program from here.
Thanks all!
Regards,
Ziang

Welcome to Apple Support Communities
Early 2011 15 and 17-inch MacBooks Pro have had several GPU issues that causes graphic corruption, and it was an issue that showed in most MacBooks Pro. However, this does not apply to the 13-inch MacBook Pro, so I think it is just an issue that has appeared on your Mac but there is not a reason for a replacement program.

IMac display issues / Trying to output at 1920x1080 through VGA

I'm having some external display issues with my 2007 Intel Core 2 Duo iMac (2.4ghz). Using the mini-DVI to VGA adapter, I plugged the VGA cable into a Samsung LCD TV (PC mode). When I originally had everything set up, I was using the TV as an extended display, with a display setting of 1920x1080.
However, I had to get a 25 foot VGA extension cable, and now my maximum resolution is 1600x1200. Does anyone know why extending the VGA cable would do this?

There could be any number of factors involved, but cheap cabling, or that your Mac does not have enough power to push the high quality resolution signal that distance first come to mind.

External keyboard and display not recognized

After upgrading to Leopard, Vista doesn't see my external keyboard and display.
Any ideas?

The display was due to Boot Camp setup deleting the old driver and needing to be run a second time. It was disappointing that the external display problem wasn't fixed, but at least release 16902 finally fixed that issue.
The keyboard is recognized if I unplug and replug it, but it has to be done each time I boot Vista.

Macbook display issues

Hello!
Way back a few months ago when I purchased my MacBook, I had some display problems from the beginning. I talked to a service rep and they walked me through some potential fixes but eventually sent out a box for me to return my macbook in for repair (I am an hour and a half away from closest apple store). I am a full time student, however, and did not ever get a chance to send it in. Later, I had issues that made my macbook unusable, and was forced to send it in. I was hoping that the display issues would have been fixed as well, but they weren't. Luckily, I primarily use an external display. But my problem has gotten worse and worse, my macbook is almost unusable on it's own at this point.
I know I am still under repair warranty and was hoping someone could send a box out for me to return this before my fall term begins, so I could use it for note taking again. But I can't go into an apple store and I don't have phone support anymore, so I have to post this on here because there is no email support.
I hope someone can help me!
Thanks a lot,
KJ

I know you only get something like 30 days phone support but i think thats more for simple things if you get stuck or need help using something. You have a full years warranty so if you have a problem within the year you should be able to phone them up and get your problem sorted out under warranty. They will probably ask for your serial number but you should not have to pay for phone support. Just call the number listed on the apple site.
When you speak to them make sure you tell them ALL the problems you have with your machine. When i sent mine in i made a text file titled 'Problems with this macbook' and left it in the middle of my desktop with the background image turned off to make it more visible. I dont know if the engineer ever read it but its an extra step that might be worth taking. You should still tell the guy on the end of the phone about all your problems though. They may well assign a work order to your machine going by what you tell them so if you only tell them about one problem the engineer that looks at it might not know to look at anything else.
