IMac 27'' little bit blurry after changing resolution.

Hello. I recently bought a 27'' iMac 2013. As the screen is too big I changed the resolution from 2560x1440 to 2048x1152. But it look a little bit blurry now. 2560x1440 is really good but texts and other thing hard to see. Is that normal? I think Apple should do something about it. My eyes are really fine but even for me it was hard to see texts. They are too small.

in windows one can change dpi of text and the likes in the video settings this partly does what you want
I don't believe it's possible with osx at least not unless one use a thirdparty program
I say partly because while it makes text bigger and easier to read some applications looks a bit odd compared with normal
in osx are some tools in the acccability in system preferences where you get a loop but I never really played around with them'
also cehck out this

  • Satellite 4080 xcdt, small Picture after changing resolution to 800x600

    Hi.
    After changing the Res. to 800x600 or lower (while playing an older DOS-Game), the screen is reduced to postcard-format.
    Has Anyone an idea to solve this problem,(other display-driver or s.th.)?
    Greetings, R.

    Hi Ralf,
    I believe there is a setting in your BIOS to force the screen image to stretch to fit the available space.

  • Monitor went black after changing resolution

    I changed my mac mini resolution to something higher. The screen went black and now it never shows anything on it anymore. I turned off the mac and the monitor but still the same problem when I turn the mac back on. How can I get to see the screen again?

    Hello Bill,
    Welcome again to the Apple Forums.
    Most likely you have picked a screen resolution and/or screen signal frequency that is not compatible to drive your monitor.
    You have a couple options available to you.
    Option 1.
    Restart your mini computer and turn off the monitor.
    Let the mini computer start up completely.
    The mini will detect no monitor is detected and default to a lower resolution and frequency setting.
    Turn on your monitor after the mini has completed its start up.
    Option 2.
    Restart you mini computer and leave the monitor turned on.
    Hold down the shift key on the keyboard after you hear the start up tone.
    The mini will start up in Safe Boot mode and switch to a lower resolution and frequency setting.
    Cheers

  • No video signal after changing resolution...

    Hi guys...
    I have had this issue in the past.
    I have an ATI Radeon 9000 on a G4 Quicksilver. I have had it hooked up, for the last few years, to my Toshiba Regza 42" LCD utilizing a DVI to HDMI connector.
    Recently, my wife and I have decided to sell the Quicksilver so we flattened the hard drives and did a clean install of Leopard.
    From there, I upgraded Leopard from 10.5 to 10.5.8 and then went to change the resolution to 800 x 600 as I had in the past so I could test out VLC's speed. The signal went out...and never came back.
    Not panicking (I had a prior issue on this board and it was fixed), I restarted in Safe Mode. However, when I went to Safe Mode, the resolution I wanted was already chosen and when I clicked on it again and restarted OUT of Safe Mode, I'm STILL getting "No Video Signal" on the Regza.
    I've also noticed that while 800 x 600 works (in Safe Mode), you cannot restart into that resolution AND it's surrounded by black bars rather than filling the whole screen like it used to. I don't get this.
    I've been told that I may have to erase the entire set of drives again and install only up to 10.5.6 or lower as this is an Apple resolution issue.
    I REALLY don't wanna do this.
    Is there a way to fix this issue?
    Thanks!

    1920 x 1080 and 800 x 600 so far. I haven't had the guts to try anything else. I lost Safe Mode by going to 640 x 480 once as well as 1024 x 768.
    The issue is that the Regza can be set to the first to in Safe Mode but will not reboot to these resolutions when booting normally.

  • My Pogo game does not fit the game window even after changing resolution pixel only on Firefox.

    In Pogo games my game is too large for the game window. I tried various pixel resolutions and game is still too large. Extending the window will not help.

    What site?

  • T43p-blue screen after changing display settings

    Display turned blue after changing resolution obviously to some wrong settings, how to revert the process when cannot see anything but the start up sequence?

    go into the safe mode and change the resolution, or at least reinstall the driver. Press F8 during initial startup of the laptop.

    Hello All...
    Back after a brief absence, things look a little bit different.
    I'm trying to take a 16 minute mini dv video and compress it for use on the web. I'm interested in any suggestions you may have on settings for the video and audio tracks. I've tried using Sorenson 3 (15 frames, key frames set to automatic, 320 x 240) for video and IMA 4:1 (mono) for audio. The resulting video looked great but the file size came in at about 255 Mb.
    Thanks!

    Thank you for the replies.  Everyone was correct about the jack, interface, and phasing problems.  I have been unplugging my motu audio interface and then using headphones at work.  I have not changed any detailed audio output settings in logic.  When I read that the jack might be a problem I tried switching headphones.  This actually helped.  I am using dre-beats headphones and they seem to be having issues with the mac/jack-(the phasing/panning problems.  I can use these headphones with other devices but not the mac.  I have to use ipod ear buds and the phasing seems fixed.  Hopefully this information is helpful to someone else. 
    If anyone knows how to correct this issue please let me know its difficult to know what my final mixes are going to sound like and I have had to keep bouncing everything into i-tunes- sync to ipod and then listen in my car radio.

  • My iphone4s' screen is not clearly white color, it has a little bit yellow color, how to change it?

    my iphone4s' screen was not the pure white color, it has a little bit yellow inside. how to make it to the pure white color, Can i change my iphone 4s to a new one?

    There's a brightness control in Settings. The yellow tinge occurs with some phones; if it were mine I would take it back to the Apple store and get it replaced, but some people say it fades with time as the glue cures.

  • After 1T hard drive exchange, my imac works a bit strange.

    I got my 1T hard drive exchanged after received the letter from Apple to suggest 1T hard drive I had may have problem. However, after change, I found that my Imac work slower than before,some time it's freeze for 5-10 seconds. and some times when I closed the one of the taps from safari, the other tap would show the broken image from the closed tap. It make me scare whether the monitor is not going to  work any more...

    Call Apple to purchase replacement discs or order a copy of Snow Leopard from Apple's Online Store. Follow these instructions:
    Drive Preparation and Install Snow Leopard
    1. Boot from your Snow Leopard Installer Disc. After the installer loads select your language and click on the Continue button.  When the menu bar appears select Disk Utility from the Utilities menu.
    2. After DU loads select your hard drive (this is the entry with the mfgr.'s ID and size) from the left side list. Note the SMART status of the drive in DU's status area.  If it does not say "Verified" then the drive is failing or has failed and will need replacing.  SMART info will not be reported  on external drives. Otherwise, click on the Partition tab in the DU main window.
    3. Under the Volume Scheme heading set the number of partitions from the drop down menu to one. Click on the Options button, set the partition scheme to GUID then click on the OK button. Set the format type to Mac OS Extended (Journaled.) Click on the Partition button and wait until the process has completed.
    4. Select the volume you just created (this is the sub-entry under the drive entry) from the left side list. Click on the Erase tab in the DU main window.
    5. Set the format type to Mac OS Extended (Journaled.) Click on the Security button, check the button for Zero Data and click on OK to return to the Erase window.
    6. Click on the Erase button. The format process can take up to several hours depending upon the drive size.
    7. When completed quit DU and return to the installer. Install Snow Leopard. Once you boot from Snow Leopard you should open Software Update and install all the available updates required. After you complete this and restart the computer open the App Store application in the Dock or Applications folder.
    8. Sign into the App Store with your Apple ID and password. Purchase and download Lion.
    9. After Lion's installer downloads, install Lion.

  • Login screen changes resolution after a second

    It' weird but my login screen on this laptop with arch always loads up at a lower resolution (larger font) then after like one second the screen refreshes into a higher res login. Didn't really know where to search for this issue, does anyone have any idea why it does that? There's also like a randomly red-purple colored T character around the top of the screen doesn't really bother me but maybe it's related somehow. Also I'm describing this in context of an alienware m15x with nvidia geforce GTX 260m
    And it's being driven by the nouveau pkg xf86-video-nouveau

    Yes, but not for early boot. That needs to be enabled manually. (Nothing to install, though.)

    I used to have a problem with Ubuntu/Debian, where by my screen would randomly flicker for a second and random noise/garbled black and white static would appear until I played with something on screen. Then everything would settle down for a while, the resolution would remain the same though. That's never happened on Arch..
    I should be clear: it happens as part of the boot process - not when the machine is up and running. It always happens at the same point when the nouveau driver is loaded. The reason it changes resolution is because it is switching to a driver which supports the graphics card properly and so I'm getting native resolution after that point but not before. I can't say it bothered or bothers me. The first time it was heart stopping because nothing, nothing was working and I felt I'd tried everything to get the graphics to be bearable but after that it was just part of the boot process and I was always quite pleased to see it because it meant that the graphics driver was loading! (I had trouble getting it to work and ended up having to blacklist stuff or something. Since this was my first install of GNU/Linux, getting it all working on non-ideal hardware was somewhat like being thrown in at the deep end, even though I used Debian. At least, so it felt at the time... People kept telling me to use the nvidia drivers and I kept explaining that I could not do so because they didn't make them for PPC!)

  • TS3048 [SOLVED] after changing batteries: keyboard did not connect to iMac

    After changing the batteries of my wireless keyboard, it refused to connect to the iMac.
    It took me half an hour to discover that it was connected to my iPhone instead.
    So if you ever created a BT connection on your iPhone, make sure it does not interfere with the iMac when you swap batteries...
    I simply removed the BT connection on my iPhone.
    Hope this helps others.

    Please  use Apple's Troubleshooting wireless mouse and keyboard issues located by clicking http://support.apple.com/kb/ts3048. Also it is wise to keep a cheap USB keyboard & mouse around in the event of bluetooth problems.

  • I spilled a little bit of soda on my keyboard ( more like big drops) and my computer won't turn on but it will still charge.  After i spilled it it kept trying to turn on and off by itself until i finally just shut it down

    I spilled a little bit of soda on my keyboard ( more like big drops) and my computer won't turn on but it will still charge.  After i spilled it it kept trying to turn on and off by itself until i finally just shut it down.  Today i tried to turn it back on ( i spilled it last night) and now it won't turn on but when i plug it in the orange light comes on so it still charges.

    TBF: You may have been lucky enough not to cripple your MBP immediately with your spill, but a spill such as you describe will have left obvious traces if you ever need to take your machine in for a repair of any kind. And as soon as evidence of the spill is found, any chance of the necessary repairs being performed under warranty will be gone.
    Taking the machine in now to be cleaned and have the greasy parts replaced will be expensive, but doing so may save whatever remains of your warranty. For a price, Apple will restore the machine to like-new condition, and at the very least, you will then have a 90-day repair warranty on it. If you have significantly more time than that remaining on your original one-year warranty, and especially if you've bought the extended AppleCare Protection Plan, it would probably be worth taking the machine in to a Genius Bar for a look-over. Ask whether, if you have Apple clean and repair the machine now, your new-computer warranty and AppleCare plan will be reinstated afterward or whether all you'll have is the short repair warranty from now on. If the spill will negate your warranty and AppleCare even if you have Apple clean it, then the cleaning probably isn't worth paying for. But if paying for the cleaning will get your warranty and AppleCare reinstated, it may be worth doing.

  • Problem logging into my iMac after changing iCloud password

    I changed my iCloud password and now can't login with the new password on my iMac but it's working on my MacBook Pro.  I'm using the iCloud password option instead of a local password.  How do I get the iMac to see that it's changed?  I can still log in with my old iCloud password.  I've rebooted and I've signed out and back into iCloud but it still isn't picking up the password change.
    Thank you

    So, being the impatient tech guy I am I figured it out.
    1) Sign out of iCloud in System Preferences
    2) When prompted create a local password
    3) Log back into iCloud with the correct password
    4) Go to System Preferences > Users & Groups and select your user account
    5) Click Change Password
    6) Select the option to use your iCloud password
    7) Enter your current local password and your current iCloud password
    Done!
    It's now working correctly for me.  I'm still not sure why it never automatically synced but I'm not going to go digging that one up.
