IMac :: 24" With ATI Radion HD 4850 Display/fixing Late Display?
Sep 22, 2009
i am having a weird problem with my brand new imac.. I bought it custom made last friday with ATI Radeon HD 4850. Now here is my issue.. Every time i boot up it takes a while for the screen to turn on. I hear the start up sound and HDD working and all that but screen stays off for another 5+ sec. before finally going grey before apple logo comes up. Now I thought this isn't an issue since i did order it with ATI card instead of standard Nvidia. Figured different cards react differently. However, later on after playing a game for few hours and doing a restart it would do the same thing, but the screen would never turn on. Just stay black forever until i shut it down and wait a minute or two then power it back on. So to clear this up. What happens is, i push power button, start up sound happens, then black.... like it is off, not even the back light. This only happens every few days, not every restart.. I reset SMC, PRAM, ran hardware test, spoke with apple on phone, went to genius bar, and after all that and being passed around now the apple engineers are looking into my problem and i am expecting a call back from them. So i guess my question is, is there anyone else with this setup (ATI Radion) that has this issue?
As can be seen from the screenshot below, each morning when I put the iMac on... they appear right before the login screen for approx 4-5 seconds. Is this something to worry about? Done a PRAM reset
The title says it all really... Quite a simple problem that I can't find any answer to!
I've hooked up my 30" Apple Cinema Display to the new iMac 27" and the highest resolution I'm getting as an option is 1280x800... The iMac correctly detects the ACD as a Cinema HD display but limits my resolution. Why oh why?!
Purchased a brand new 27" i7 imac a few weeks ago, display is awesome!!! I was using my old 28" LCD monitor from my PC and running dual displays on the iMac. The 28" LCD monitor annoyed me a bit because i could not get the same color/crispness/brightness that i got from the iMac. ( also it has a Matt screen and i am more into the glossy screens ) So i found a used 24" cinema display locally. Paid 600.00 and it came with 2 yrs of AppleCare. It is only 7 months old ( still have 5 months under orignal warranty ) Got home, hooked it up and it had a "hint" of yellowness to it, It wasn't a exact image of my iMacs display...I tried to calibrate it also, but it still had just a HINT of yellowness....Nothing at all major, but enough for me to be annoyed with it.
I just purchased a 23" monitor to replace my iMacs 17" display (since it has a nasty crack in one of the corners). I hooked it up fine and all, but the displays are linked, allowing me to hover the mouse to the iMac's display which I find annoying most of the time.
Is there a way to make the iMac display zone out and just use the external by itself?
As you can tell by the thread title I've got one of the latest model iMacs and I'm running an LED Cinema Display as a second monitor. When it gets to the late hours I like to watch some movies on the Mac so I figured the Cinema Display would be a nice addition to do the job.
Now here's my issue: if it's late and I'm watching movies I tend to not have any lights on, but having one of the displays on means having both of them on, what I'm wondering is if it's possible to sleep one display while allowing the other to stay active so I can watch the movie without the light from the other one distracting
I'm interested in the new iMac but could not work with a glossy display. Can anyone share their experiences of using the iMac with an external display? In one respect it seems like a waste to have two monitors but the base model costs little more than the maxed out Mini and seems like the better option.
I would be interested in seeing photos of any setups featuring the iMac and an external display.
Also, is there a way to turn off the iMac display when using an external display?
just got myself a new 21.5" imac and use to have 19" dell monitor but i sold that and wanted to know if there are any 21.5" monitors out there that look like imacs with a imac stand and black glossy border
I am trying to connect my windows 7 laptop to my iMac 27 (late 2009). The laptop is an hp elitebook 8440p with integrated intel graphics and it has a display-port. I bought a displayport to minidisplay port cable and connected to my iMac 27; nothing is happening. My laptop says no displays detected and the iMac does nothing when i press command-F2...i've also tried command-F2-Fn. It doesnt even seem to respond to command-F2. Also under the keyboard shortcuts menu there are only two shortcuts for displays and its to dim and brigthen the display. The iMac and PC are both up to date with software; OSx 10.7.4 Lion.
I can not figure out how to connect the power on the cinema display. It looks like it would plug into the back of the mini where the macmini would normally plug the power in. Not sure if I am missing something. I also do not know if I need to plug all 4 connections the video, usb, hdmi, and iguess what is the power plug in or just certain plugs.
This is an odd, intermittent problem that started about a month or two after purchasing my fall 2011 MBP 15 (i7 2.5, 16GB RAM). This problem started, went away on its own, and now it's back after about two months of being trouble free.When I close my computer, it doesn't go to sleep.The slit light on the right front of the computer does not go into its slow flash mode; however, it does light up solid, and theng it stays lit.When I open the lid, the computer wakes up immediately (it was never "sleeping" to begin with), but then after a second or two the screen fades to black.The screen can be brought back to life by pressing either of the brightness buttons on the keyboard.I took it to the Genius Bar, and of course I couldn't replicate the problem for them.When I got back home, I decided to test the computer plugged in, and that's when the problem came back.I don't know why it went away previously.So, in summary: The issue only occurs when the computer is plugged in.The sleep problem existed before I installed 3rd party RAM and Parallels 7, and they exist now after I have installed the RAM and new software.I use a wireless mouse, and the little dongle has no effect on the sleep issue - the computer will not sleep (when plugged in) either with or without the dongle in a USB port.The battery charges just fine.All of my software is up-to-date, and I'm running OS X 10.7.3I have checked for the Flashfake malware, and I do not have it.I am running Sophos Anti-virus; I have done a scan, and have found no threats.They flashed my PRAM and ran some tests at the Apple Store and everything passed.
Long story short, I now have a late 2008 15" MBP with a broken display housing, LCD housing, and glass bezel. The LCD itself, along with the iSight etc., is functional. I have the opportunity to buy a display assembly for the mid 2009 MBP, including a new screen, for a good price.
Would replacing the entire display assembly with the mid 2009 assembly work? Or could I buy the new assembly and simply replace the screen with my current one? Essentially, what is the compatibility of the two units. I'd prefer the mid 2009 screen for obvious reasons.I searched the forums here, as well as searching many other places, and I have not found the answer.
I have a MacBook Pro late 2011 with Lion installed. The Performance is less than I expected if compare with my old Macbook with Snow Leopard installed. Connect to Apple's Thunderbolt Display Performance goes doen to very, very, very, very slow.For Example to load a JPG in Preview it takes more than 30 seconds until 1 min to load. Same to start iWork like Pages or Keynote.Sometimes Safari freeze, loading images or loading plugins like flash animations. Generally Lion works with low performance and I wish Snow Leopard back. But my Mybook Pro late 2011 is not compatible to install Snow Leopard on it.
My wife's macbook monitor is destroyed due to happy 2 year old. It won't be worthwhile to replace the monitor and it is not fixable without some expensive work being done on it, therefore I would like to use our TV as an external monitor and retire the macbook to being a mediia computer. I have connected it to the TV, and I see an empty desktop, as far as I can determine it looks like it is treating the TV as a secondary display - that the desktop is extended onto - so I cannot actually interact with the normal desktop. When I try to run things using keyboard shortcuts I hear some sounds of things starting, but I don't see anything on the TV. So what I need to do is to have some way to tell it to treat the secondary display as the primary display.
i own a 27" i7 iMac. I currently use a Hanns.G 28" LCD monitor that i used for my PC but not use it as a 2nd display for the iMac. Everything works great actually but the displays colors are just to different and tend to annoy me. The iMac is Clear, bright and Crisp, The Hanns.G is matt finish screen and though its bright, its a bit washed out looking and no matter how hard i try to adjust the Hanns.G in the monitor settings i cannot get the colors to look the same as the iMac. So i was thinking about getting a 24" ACD ( found one used w 2yr apple care, local for 600 ) and was curious will the display ( color, brightness and crispness ) look the same as the iMacs display?if i come out of sleep or standby, the Hanns.G looks really nasty until it warms up )
My employer is giving me a new HP (nope, no macs there ). I am thinking of getting the 12" 2540P Notebook for portability. Question is if I can connect that to my iMac 27" and use the iMac as a monitor?
There is a Displayport on the HP - can a simple cable like this do the job?
I'm getting a high resolution, and it looks alright, but it's not fully using the widescreen. That's "aspect" right? Well anyway, I also have a 19" display and it works perfectly. My Xbox, cable box and movies all use the full widescreen on the Acer, but the Macbook with the super amazing Mini DisplayPort doesn't even use the full resolution. What's with that? I thought the reason they had this new port and a $30 adapter was for higher resolutions!
I hooked up my macbook pro to a mini display port to a dvi -> hdmi to my tv no problem. However, when I hooked up the mini display -> dell monitor, I get nothing. The screen is black. The weird thing is that my macbook pro recognizes that a second monitor is plugged in... it just won't display anything
I want to buy the 27" iMac - but only if I can use it as external monitor for my Lenovo laptop when working from home. A the Apple store in London they said that this is possible with a Belkin converter from hdmi to mini display port (with a USB power caple to turn it into an active signal). The laptop also has a displayport.
My external display (HP w2207) seems to conflict with my MacBook Pro (15 inch Retina display, early 2013) since I upgraded MacBook OS to 10.9.4.The external display works at initial boot of Mac but does not work after OS sleeps and I attempt to awaken, and while the external display is not waking, the Retina display flashes through different screen views, which only partially reflect my normal screen, or do not reflect my normal screen at all.
I own 23 and 30" Cinema Displays. I like the 23 because everything is larger and easier to read than in the 30". I mostly work in Logic and love that I see lots of things on the 30" but the 23" is much easier on my eyes.Is there such a thing as a display with 2560x1600 (like the 30" Apple) but that is LARGER than a 30 inch so I can see everything bigger in Logic??? Maybe a 34 or 37"? Did a search but haven't come up with anything other than other 30" displays.
