Mid 2010 iMac 27" doesn't have proper pixel dimensions in TDM

I have a
Mid 2010 27" iMac
Mid 2012 15" MBP
I am trying to use my imac as a second monitor for my MBP. I have a Mini displayport to mini displayport cable and my iMac shows up as a second monitor for my MBP.
thats great, but the highest resolution is 1920x1200. When the actual resolution of my imac is 2560x1440. So the quality of the 2nd display is horrendus.
you can see here that the 1920x1200 is the highest resolution it will allow to me. Why is this? Could it have to do with the fact that on my MBP it's a thunderbolt port and on the imac it's a mini displayport?
I can't find any info on this. any help would be greatly appreciated..
Thanks

Mid-2010 iMac randomly freezing after last Windows 7 update. Help! I am a teacher and have 50 computers all behaving the same way.

I am a teacher and have 50 mid-2010 iMacs running Windows 7 in my classroom. The computers did a Windows 7 automatic update on or around April 15, 2014. After that, each computer randomly freezes. Some are worse than others. Most of the computers freeze when a USB drive is plugged in and also when a pop-up shows up on the screen - especially the Java update. I have installed the most current Bootcamp drivers and run several anti-virus program searches. I've also tried the Microsoft Fix-it program and almost everything. Uninstalling the updates did not help. Can anyone help me out?

based on what you wrote this doesn't make sense
use system restore to rollback the machine prior to this update

I just updated my RAM and I keep getting a crash report. I have a 21.5 Inch mid 2010 imac. I also am experiencing slow load times and when I try to open Final Cut it says that quartz extreme is not compatible and that I have no VRAM even though I do.

I just updated my RAM (replaced the two 2 gig cards with two Corsair 8 gig cards) and I keep getting a crash report. I have a 21.5 Inch mid 2010 imac. I also am experiencing slow load times with Photoshop and when I try to open Final Cut it says that quartz extreme is not compatible and that I have no VRAM even though I do.

There have been a few reports on here where Corsair RAM seems to have caused users a lot of grief with crashes.
The recommendation on here, mostly, is to only buy RAM from macsales.com or crucial.com as they guarantee their modules will work and offer a no quibble lifetime guarantee.
I'd put the original RAM back in, return the Corsair chips for a refund and re-order from one of those two companies.

I have a mid-2010 iMac and just purchased a 2TB TC, can't join existing wireless network with AC standard so attached to iMac via ethernet with TC wifi turned off. How do i access TC now? not showing up in disk utility or on desktop. working fine with TM

I have a mid-2010 iMac and just purchased a 2TB TC, I just found out that it can't join existing wireless network with new AC standard so attached to iMac via ethernet with TC's wifi turned off. How do i access TC now? not showing up in disk utility or on desktop. It is working fine with TM. My cheeper seagate drives etc kept crashing, so i didnt trust cheeper back up options anymore. Connected those drives to TM via firewire and could see the drives and access them.
Also, I didn't want to bridge TC with my new fios router that I paid 100 dollars for, to get N speed and also paying 10 dollars more a month for fast speed. I heard that bridging slows down everything and then there can be port issues with mail etc. I connect to the internet via airport only and it is pretty fast. Getting over 50mbs downloads and over 30mbs uploads. Plus everything in my home it connected to my fios router, airport express for music streaming, two apple tvs, vuezone camer system. I really didn't want to monkey around too much with my system. But are there other options to connect the new TC. Can't find info anywhere for this and called apple who gave me the info above. after hanging up, i see that i cant access my TC and I am wondering if i would have to reset it to turn wifi on again to make changes to the drive, turn off blinking light or repair it in disk utility if it should become corrupted.
For other with similar issues i did solve some other problems: when i connected it to my ethernet port on my iMac wifi stopped working. Found that I had to turn off the ethernet in the system>network screen, but then TM didn't see the TC so i restarted after changes and then it saw it.
Now a rant. I can't believe in this wireless age that Apple would make a product that cant join a wireless net work. The apple rep said i could return it and look for the previous TC that would join an existing wireless network. Are we going backwards?
Thanks!

Ok... it is getting a bit clearer but there are still some questions.
I connect to the internet via airport only and it is pretty fast.
I was assuming airport in this statement in your first post meant the TC or the Express.. but I now realise we are still in the mass confusion stage where apple calls everything wireless an airport. So what you mean is the airport internal card of the computer??
Also, I didn't want to bridge TC with my new fios router that I paid 100 dollars for, to get N speed and also paying 10 dollars more a month for fast speed. I heard that bridging slows down everything and then there can be port issues with mail etc.
I think this is mistaken.
Putting the TC in bridge mode plugged into your FIOS will not slow the network.. nor will it cause mail or port issues.. in bridge the TC is just a fancy WAP and switch plus the network hard drive.
If the computer is close it will be faster than the FIOS.
You can run both wireless networks with different names.. so it is clear which is which. But you can also setup roaming so the computers themselves pick which is the best wireless.
I tried extending the wireless net work and tried joining wireless network, but the TC kept crashing and I had to keep resetting the TC. the Apple support person said these, extend wireless network and joint wireless network, are no longer a connection option with the new TC because of the new AC protocol.
Thanks again!
You cannot extend to a non-apple wireless router.
You cannot use join a wireless network because when you do the ethernet ports will be cut off.
But that has not changed.. I don't think Apple support is correct.. there has been no change with the AC model.. it is simply a fact that apple routers do not work in join wireless mode other than as a dumb client. The same applies to AC as to the earlier version.. but I have asked another person to check this.
Join in the express is the only apple router that still allows an ethernet connection.
For now you best use of the TC is bridged to the FIOS. Wireless you can sort out between several options.

Mid 2010 iMac upgraded SSD, can't seem to install windows via bootcamp. Windows can't be installed on this storage device. The chosen harddisk contains a MBR-partition-table. Windows can only be installed on GPT-harddisks on EFI-systems error

I have windows 8.1 on DVD & on USB CF Reader/Card. I've followed the full steps in bootcamp, but when it restarts and its time to select the bootcamp partition to install windows (after alt rebooting to the efi startup) I get the "Windows can't be installed on this storage device. The chosen harddisk contains a MBR-partition-table. Windows can only be installed on GPT-harddisks on EFI-systems" error.
I've scoured the internet trying different solutions that seem to work for everyone else, but to no avail. I've reformatted from that screen, doesn't help. I've removed bootcamp partition and manually partitioned using disk util, leaving it empty once partition-wise, and filling it with a blank partition the second time. I've done a full back up and clean re-install of Yosemite, and nothing seems to be working.
Thats when I switched to DVD install, as I heard sometimes you can't install with a CF card. When I alt-boot, I can see EFI-windows and windows, but if I select EFI-windows, same problem as before, and if I select windows, I get the black screen of "no bootable device please insert boot disk and press any key."
I've been stuck w/o bootcamp for over 2 years now. Anyone, please help?
Mid 2010 iMac running 256gb SSD, Yosemite 10.10.1 trying to install windows 8.1

I am having the same problem. Windows is trying to install. It identifies the various partitions but says that I cannot install Windows on the Boot Camp partition or any other. I select Drive options (advanced) and Format the Boot Camp drive, but it makes no difference.
This is the Windows error:
Windows cannot be installed to this disk. The selected disk has an MBR partition table. On EFI systems, Windows can only be installed to GPT disks.
Windows cannot be installed to this disk. This computer's hardware may not support booting to this disk. Ensure that the disk's controller is enabled in the computer BIOS menu.
I am not sure what Csound1 is suggesting with that post above. There are some involved suggestions over here <https://discussions.apple.com/message/23548999#23548999> about using Disk Utility to delete the Boot Camp partition and create new ones - is that the idea?

Pixelation after upgrade to Yosemite - mid 2010 iMac 27in

I have a mid-2010 iMac 27in with 16GB of RAM, 2.93GHz Intel Core i7, and an ATI Radeon HD 5750 1024MB display adapter. I also have a second display attached which is a 27in LED Cinema Display. I have never had a problem with either display with any of the previous versions of OS X. I upgraded from Mavericks to Yosemite over the weekend and now have random pixelation. Usually blotches of Magenta pixels, quite large in some cases. Sometimes the color varies and may be like a lime green. It doesn't show up on an open windows, just on the desktop background and it shows up on both screens, but not necessarily at the same time.
I have reset the PRAM and the SMC but problem persists. This sounds like a possible driver issue, but just guessing. Any thoughts?

A client reported that this helped a lot:
Turn off Transparency:
To turn off the transparency:
Under the Apple menu, choose System Preferences
Choose Accessibility
Choose Display
Click the "Reduce Transparency" check box

Bluetooth 4.0 on my mid 2010 iMac?

Hiya,
I'd like to start using a bluetooth foot pedal (IK Blueboard) to control amplitube on my mac but it needs bluetooth 4.0 to connect which my apparently aging mid 2010 iMac doesn't have.
Does anyone know of any mac compatible usb Bluetooth 4.0 dongles? I'm searching right now and drawing a blank which I find pretty weird.
Cheers!

I have a inateck BT 4 Dongle which I am reliably informed works for Macs for exactly the same reason - blueboard connection on a mid 09 mac. My problem is that I don't seem to be able to control the dongle - still working on it so will keep you posted as to my success (or not!).

Mid 2010 iMac Windows 7 Problem

Hey there,
I have an Mid 2010 iMac running OSX Lion and I have Windows Vista installed via Bootcamp.
I have Windows 7 saved to a USB drive, and I tried to upgrade to 7 directly from within Vista but when the installation was completing I just got a black screen. I restarted a few times, but still got the black screen during the end steps.
I've tried to start from scratch about 3 times now, but it still wont work.
Can this problem be solved?

I'm experiencing the black screen crashes since I started using Windows 7. It doesn't matter if it's 32 or 64 bit, the issue is persistent. First I thought it was the updated nVidia drivers, but after putting a fresh installation of Windows I left the original Boot Camp graphics drivers and the same black screen crashes continued.
However, when I'm running various computer games which utilize lots of GPU power, crashing never happens. Then, when I exit and start using Explorer, IE, MS Office and other simple tools, my computer goes dark. I don't believe reinstalling would change anything. This is definitely a unique problem that I just can't seem to figure out.

Will my mid 2010 iMac 27inch work with Thunderbolt external drives?*

will my mid 2010 iMac 27inch work with Thunderbolt external drives?*

No. Your iMac doesn't have Thunderbolt. You'll need a Firewire or USB drive.

How do I use my mid 2010 iMac as display with mid 2011 macbook pro?

I have a mid 2010 iMac and I want to use it as a display for my mid 2011 macbook pro.
The iMac has a mini display port and the macbook has a thunderbolt port.
Does anyone know if this is possible and what I need to make it possible?
Cheers!

If the iMac is a 21-inch model, you need to use a product such as ScreenRecycler over a network.
If the iMac is a 27-inch model, click here and follow the instructions.

Use 21.5 inch mid 2010 imac as a display for 2013 macbook air?

I would like to use my 21.5 inch mid 2010 imac as a display for my 2013 macbook air. I tried using Screen Recycle, however I would prefer more of a monitor situation than a side-by-side extra screen situation. Ideally with my wireless keyboard and mouse. Does anyone have any advice, or am I asking too much from apple? Thanks very much.

Yes. With an Ethernet cable and a product such as ScreenRecycler.

Mid 2010 iMac Problems

I have a 21.5" Mid 2010 iMac with 16 GB RAM, running 10.8.5.
Problem #1
It's recently started doing some odd behavior when waking up from sleep. I have the screen saver set to come on after 5 minutes of inactivity and then the display and computer both sleep at 15 minutes.
When I try to wake the computer up by moving the mouse, it takes anywhere between 5-10 seconds for the password prompt to pop up and then it's another 2-5 seconds before it will let me type in the box. It also seems that when the computer sleeps, the wifi is disconnecting, because the computer won't have received any new email and all my mailboxes have the little exclamation symbol next to them.
After about 5 seconds or so once the computer fully wakes up, it reconnects and pulls all my new mail.
Problem #2
This usually happens when I just browsing facebook or youtube or something like that, but when I switch over to another application and come back to Safari, I will get the beach ball for a few seconds and then the computer will freeze. The mouse cursor turns into the little "I" symbol like when you go to type or highlight text. The only thing I can do at this point is a restart.
Problem #3
I have spaces set up with Safari, Mail, iCal, and iTunes in spaces 1, 2, 3, and 4. Most of the time I'm in Safari, but if I move to another space either with the mouse or the keyboard shortcut, to check for new mail, for instance, and go immediately back to Safari, it will on it's own jump back to the space I just left. It happens with any space no matter what. I use the option + arrow keys to go between spaces a lot.
Does anyone have any idea why this happens? Thanks for your help.

Please read this whole message before doing anything.
This procedure is a test, not a solution. Don’t be disappointed when you find that nothing has changed after you complete it.
Step 1
The purpose of this step is to determine whether the problem is localized to your user account.
Enable guest logins* and log in as Guest. Don't use the Safari-only “Guest User” login created by “Find My Mac.”
While logged in as Guest, you won’t have access to any of your personal files or settings. Applications will behave as if you were running them for the first time. Don’t be alarmed by this; it’s normal. If you need any passwords or other personal data in order to complete the test, memorize, print, or write them down before you begin.
Test while logged in as Guest. Same problem?
After testing, log out of the guest account and, in your own account, disable it if you wish. Any files you created in the guest account will be deleted automatically when you log out of it.
*Note: If you’ve activated “Find My Mac” or FileVault, then you can’t enable the Guest account. The “Guest User” login created by “Find My Mac” is not the same. Create a new account in which to test, and delete it, including its home folder, after testing.
Step 2
The purpose of this step is to determine whether the problem is caused by third-party system modifications that load automatically at startup or login, by a peripheral device, or by corruption of certain system caches.
Disconnect all wired peripherals except those needed for the test, and remove all aftermarket expansion cards. Boot in safe mode and log in to the account with the problem. Note: If FileVault is enabled on some models, or if a firmware password is set, or if the boot volume is a software RAID, you can’t do this. Ask for further instructions.
Safe mode is much slower to boot and run than normal, and some things won’t work at all, including sound output and Wi-Fi on certain iMacs. The next normal boot may also be somewhat slow.
The login screen appears even if you usually log in automatically. You must know your login password in order to log in. If you’ve forgotten the password, you will need to reset it before you begin.
Test while in safe mode. Same problem?
After testing, reboot as usual (i.e., not in safe mode) and verify that you still have the problem. Post the results of steps 1 and 2.

My mid 2010 iMac is running very slow.

I have done all the usual things such as checking the disk is clean, closing unnecessary programmes etc. I would rather not replace what seems to be a good machine. Any ideas? Below is an etrecheck report on the machine:

Its bizarre to still see cleanmymac on report below. It wasn't listed in applications, and I just found a couple of files that I deleted. Anyway, here is the report:

Windows 7 blue screen on Mid 2010 iMac running 10.8

I had previously had the 64 bit version of Windows 7 Home Premium running on my mid 2010 iMac running 10.7. However, after upgrading to 10.8, my Windows installation would blue screen after booting. I suspect this was due to upgrading to 10.8 as I didn't make any changes to my Windows install because I only use it for gaming.
I've since removed the Windows partition, and tried a clean install via the Boot Camp Assistant. Windows installs just fine and boots cleanly. However, after installing the Apple Boot Camp drivers (freshly downloaded during the Boot Camp Assistant process), Windows blue screens upon booting. I can repair the Windows install using the built in process, but any attempt to install Apple's drivers results in blue screening. I've tried a clean Windows install and redownloading Apple's drivers several times with no luck.
Does anyone else have any suggestions on how to resolve this problem? Thank you for your help!

I do see this. And I suspect Windows updates. Not Apple (though I would be the first to suspect those too).
iMac graphic drivers for Windows seem touchy and common. The April Windows monthly patch updates hit a few iMac users.
One person found that if they only did updates in smaller steps and not all at once they were fine.
Tuesday this week was another Patch Tuesday.
Games, heat, disk blocks, even RAM errors - one person recently we went round and round... bad blocks not heat, new disk drive and they were 100% stable and rock solid but was hard to rule out. Windows though is easier to test RAM and sectors. And Lion was not even aware or sensitive to those bad sectors and read errors OR RAM errors that Memtest clearly showed (run in OS X).
One person had upgraded RAM, low and behold the new DIMMs were just not fully pushed in and seated and making good contacts.
Try to rule out hardware. Maybe you stumbled on bad block being used now. Run chkdsk if nothing else.
And when updating or preparing to, run Registry cleaner in CCleaner first, Go To %TEMP% and remove everything there. Make a system backup image to another disk drive (NTFS) or with WinClone 3 (HFS, $20) or CampTune ($20).
Or it could just be uninstall one driver at a time, start with GPU, look at what was last installed. Windows drivers are not desireable for GPU. Get the one from AMD or Nvidia instead.
