Screen Resolution Troubles After Using HDMI and Converter

After using a StarTech HDMI converter to watch Netflix on my television, the resolution on my macbook pro is messed up. If I close Netflix the resolution returns, but after trying to use other programs like iPhoto and iMovie I ran into the same problem. As soon as I open those apps the resolution gets distorted and the screen is blurry. Like with Netflix, as soon as I close those apps the screen resolution returns to normal. Also every time I connect the converter and HDMI cord from my Macbook Pro to my television the resolution goes blurry, but the resolution is perfect on the television.

  • Blue Screen error message after using Rescue and Recovery.

    Good morning - I unfortunately had to use the IBM Rescue and Recovery feature to restore my factory settings.  However, now my computer is giving me a blue screen error during the startup process.  Unfortunately it is not on the screen long enough for me to get too much information from it, but I have been able to get win22n51.sys as being some sort of error message.  If I start the computer in safe mode it will load without the error.  If I use the safe mode plus networking it gives the error.  So I'm assuming it has something to do with the network drivers?
    I would appreciate any ideas you all have for resolving/further diagnosing this problem.
    Thank you!

    Hello,
    Perhaps this Lenovo knowledgebase article, "XP Crash: System may hang or restart with a previous version of the Intel PRO 2200BG Mini PCI adapte..." will be of help to you in resolving the problem?

    Is this an app bbbc?  IF it is I would contact the app developer and see if they can resolve the issue for you.
    also take a look at the reviews and see if other users are having the same issue and see if they have a resolution.

    Is it wise to keep the Nikon camera files "DSC's"  after downloading them and converting to DNG files via Adobe converter for lightroom use. In other words do the DNG files have all the raw data I would ever need in processing or should I save the camera's DSC files?

    DNG files do not contain some metadata supplied by the camera, which can be used by the manufacturer's software. Thus, if you don't keep the original Raw photo, you will lose this information.
    If your 1000% sure you're never going to use the manufacturer's software, then this isn't a problem. But who can be sure what software you will be using 10 years from now?

    hello sir my iphone screen turns off after using 2-5 minutes what would be the problem please help me out

    To make sure that this is not software related, set it back to factory settings, without using any backup data afterwards. Set up the rest of the personal settings manually and test the phone. If it still does not work, this is a hardware issue and the phone has to be serviced by Apple or an Authorized Apple Service Provider:

  • After Effects CS4 and converting to a lossless format

    I posted in the Adobe Premiere forums about an issue I was having with my renders. If you want to read it then you can check it out with the url below.
    http://forums.adobe.com/message/2622969#2622969
    What I have figured out is that After Effects does not like my AVCHD files I get from my camera. (They are h.264 in an ,m2ts file type and not mp4)
    The issue is that I get "echos" or skips when I render something in After Effects or render with Media Encoder via dynamic link and Premiere Pro CS4.
    What I am not familar with is the types of files that many of you who are more expereinced than I am use for After Effects when you need to convert to a lossless format (or one as close as you can get to being "lossless."
    I was wondering if someone could recommend the kinds of files I should be converting to and if you have a good method of converting them. Not that I want people to discuss other software here, but if you do not use Adobe programs to convert, then what kinds of files do you convert to?
    In other words, where do you recommend I begin reading or researching this because a lot of companies sell conversion programs. I currently have one that I paid for but it does not do the job I need it to do for HD. I would like to keep it as close to HD quality as possible.
    FYI I generally will do video work with some effects and green screen work in After Effects. My output is video. If you have any other questions about my process, then please do not hesitate to ask me. Other than that, I appreicate anyone's guidance.

    Yeah, AE does not like video files with interframe compression. It processes video in a completely different way than a non-linear editing program like Premiere does. My friend Dave LaRonde from the friendly forums at CreativeCOW.net explains it this way:
    If the footage you imported into AE is any kind of the following -- footage in an HDV acquisition codec, MPEG1, MPEG2, mp4, m2t, H.261 or H.264 -- you need to convert it to a different codec.
    These kinds of footage use temporal, or interframe compression. They have keyframes at regular intervals, containing complete frame information. However, the frames in between do NOT have complete information. Interframe codecs toss out duplicated information.
    In order to maintain peak rendering efficiency, AE needs complete information for each and every frame. But because these kinds of footage contain only partial information, AE freaks out, resulting in a wide variety of problems.
    You have experienced this delightful problem for yourself.
    There are several different file formats that people use. Uncompressed AVI is one as is Quicktime with the animation codec. However, lately folks seem to prefer Quicktime with the PNG codec (not a PNG sequence). It produces a significantly smaller file size, but is still effectively lossless.
    You can use the Adobe Media Encoder to export it out of Premiere to use in AE.

  • Anyone experiencing screen resolution problems after latest Mavericks Update?

    Anyone got a blurred monitor after the latest Mavericks Update?
    I am running  Mavericks 10.9.2 on a Mini Mac with a Logic TV/Monitor. Since the latest Mavericks update I no longer have the option in settings to scale to 1600 x900. Since this gives the best picture on my monitor I now have either a blurred screen with large text or a blurred screen with very tiny text. No other options that give a 'normal' display seem available now, after allowing the 'Update'. The update claims to be addressing faults on the MacBook display, which it may well do, but it has also apparently screwed up Mac Mini screen resolution Options for some of us.
    I have reverted back to 10.9.2 and turned off automatic updates, but I can't stay that way indefinitely.
    I've tried to find an e-mail address or phone number to log my complaint to Apple but to no avail. (I guess they would otherwise be inundated with customer complaints so keep that kind of information under wrapps). Anyone got any ideas?

    I'm not having any problems with dual DVI connected Samsung 21.5" monitors in 10.9.3
    What connection (adapter, cable, etc.) are you using..?

  • Screen Resolution trouble on Toshiba Satellite l775-s7307after reinstallation of Windows 7

    I was having troubles. Had browser malware that couldn't be contained, and I had other issues, such as, getting the blue screen of death on a regular basis.....I wiped the HD, and reinstalled Windows 7-32 bit, and downloaded and installed all the drivers for this model from the Toshiba website, but I seem to be struggling with readjusting my screen resolution to where it should be....It won't set any higher than 1024 x 768.
    Any ideas?

    In the future, I'd recommend performing a system recovery rather than reinstalling a clean copy of Windows. A system recovery will include all applicable software.
    You installed the latest Intel display driver?

  • Screen resolution switches while using Powerpoint & hyperlinks

    Hi.
    I'm using Office 2011 on a Macbook Air. I use PPT to teach and my classrooms have integrated projectors (VGA connection). My PPT runs and displays well. However, I often put hyperlinks in my slides so I can quickly access webpages. When I click on a link from PPT, the PPT slide fades (as it should) and the browser opens, but the screen resolution falls to 800x600 and the web pages are displayed much too big. Any reason why clicking on an hyperlink in PPT switched my screen resolution? And any trick to avoid this?

    DvlFig,
    Are you referring to the screen sizing of the actual Remote Desktop Window?  If so,
    this page offers this solution to saving your screen settings for future Remote Desktop sessions.
    How do I change Remote Desktop Connection settings?
    You can change different settings for your remote connection, including the size of the remote PC's desktop, the audio, and the connection speed.
    Open Remote Desktop Connection by swiping in from the right edge of the screen, tapping
    Search (or if you're using a mouse, pointing to the upper-right corner of the screen, moving the mouse pointer down, and then clicking
    Search), entering mstsc in the search box, and then tapping or clicking
    mstsc.
    Enter the name of the PC you want to connect to.
    Before connecting, tap or click Show Options, and then make the changes you want on the
    Display, Local Resources, Programs,
    Experience, and Advanced tabs.
    If you want to save these settings for future connections, tap or click the
    General tab, and then tap or click Save.
    Tap or click Connect.
    Hope this helps!

  • Login Screen Resolution Low after Mavericks install

    After installing Mavericks OS X 10.9 on my 13" Mid-2011 Macbook Air, the login screen resolution is not correct. The icons are huge and the resolution is very low and grainy. I Only one of my user login choices was visible. Once logged in, the resolution is correct, but with some strange issues such as the Apple icon in the upper-left corner of the screen is invisible until it is hovered over. The App store locked up. I had a bouncing folder named "sbin" appear in the dock, but I could not click on it or open it. That has not re-appeared after rebooting.  If I boot into Safe Mode, the login screen resolution is correct.
    Any ideas how to fix this?  Thanks.

    Dominic23,
    Thank you for the suggestion. I tried that, but it didn't work. I even let it cycle through a couple of times before allowing it to boot normally. I also tried deleting some of the plists preferences, but that didn't work, either. I also noticed that any changes to the screen preferences causes the "sbin" folder to temporarily appear bouncing on the dock. I'm thinking there may be a damaged or missing file, but I really don't know how to troubleshoot this. I've been a PC techyt for decades, but I'm a newbie on a Mac.
    Thanks.

  • Screen burn in after using stopwatch

    I have a flashing 0 in the top right of screen after using stopwatch - anyone else?  Any solutions?

    This is happening on my iOS 7 devices too. It looks like it's a hardware issue caused by the software. The rapidly changing numbers are burning themselves into the screen. The reason it didn't happen on previous iOS is because that last digit was left out and there was no fast changing number.
    If that's the case, there is nothing we can do but wait for Apple to realize this and get rid of that last digit in the next update.

  • Audio grayed, non-adjustable after using HDMI cable

    I have just installed Lion on a 2.66GHz 13in MacBook Pro7,1. After connecting to a TV monitor via the Apple HDMI cable and then disconnecting I am unable to adjust the audio on the internal speaker output. The audio button on the menu bar is grayed out and the physical audio controls show a Ø symbol as unavailable. The device "Internal Speakers" states "The selected device has no output controls". I have rebooted several times to no avail. I have tried various combinations of re-connecting the monitor, rebooting, disconnecting, but there is no way I can get the internal speakers or the volume controls to work.
    When I connect an external speaker via the headphone socket the sound settings are resurrected and the audio control button is reinstated.
    I have used a late 2010 MacBook Air 11, also running Lion,  with the same monitor and same cable but have not experienced the problem.
    Can anyone suggest what I might try to get things back to default?

    Some HTIB systems only switch HDMI and pass its audio, but don't process the audio.  My Yamaha HTIB is an example.
    You need to run a separate optical or coaxial audio cable from your sources to the HTIB receiver.  I do not reccommend downgrading to component - continue with HDMI, just use it only for video.
    In my case:
    PS2 to Yamaha optical - since the PS2 doesn't do HDMI and is my only component device, video goes directly to the TV
    Cable box to Yamaha is HDMI + coaxial (Yamaha only has two optical inputs)
    PC to Yamaha is DVI-to-HDMI + optical (Even if the Yamaha did process HDMI audio, this connection would need the optical cable anyway)
    There is an HDMI cable from the Yamaha to the TV.  The Yamaha can switch between cable and PC inputs for me.  I need to switch inputs on both the TV and the Yamaha for the PS2.

  • Screen resolution problem after i-tunes installed on XP pro

    Just purchased 5th Generation 60Gb for my daughters 16th Birthday which starts in about 14 minutes! Loaded the software on her XPpro service pack 2 laptop. When itunes executed the screen resolution drops to 8 bit! It can be changed in control panel and all works fine. but each time re boot itunes and the problem returns!
    Loaded on my desktop and everything fine also. tried the ms config stuff as per site and immediate problem when ms software disabled. Would seem to be a software conflict and compatability problem. The laptop is a fujitsu which is 2 years old. the older version of i-tunes which she downloaded about a year ago worked ok. Sadly we uninstalled it before installing the new version from the disc. Tried update from the site but it indicates the DC version is the latest.
    Interesting to read some of the problems that flks have had with the ipods. This one seems OK but does have a 'do not disconnect logo which hangs up and doesn't go away. However, if I do disconnect the computer 'burps' at me then all is well and forgotten!
    Oh yes. how do you delete unwanted songs once uploaded? Is there a simple 'delete' button?
    Any thoughts anyone as I've now spent all evening on it and it's her birthday in the morning (8th June)
    thanks in anticipation
