Lightroom 6: display random flashes and Pixelation

I've recently set up a new computer, with Windows 7pro, graphics Nvidia Quadro 1200 HP z240 & Samsung CF390 series 24 inch monitor curved, for Lightroom, updated the OS, drivers and related programs content before installing Lightroom.  I especially liked that the computer had no bloatware, so conflict of program should not be a problem.  Only when using with Lightroom high and active (partial or complete window display) will I get erase display random, momentary.  When the display is in place and only with LR running also make pixelation on the whole of the workspace of LR (see image).  I tried to reinstall LR and setting the parameters on the display, the video card and the computer, but nothing seems to work.  I welcome suggestions of what could be the source of this problem, because I was really looking forward to back up a computer 13 "laptop for use of LR.

I had posted this suspect, it can be linked to the comparability of the Quadro 1200 and Lightroom.  Turns out that the problem is the cable between the computer and the monitor.  The graphics card has output mini DisplayPort (DP), while the monitor requires HDMI.  If it was the use of a mini DP to HDMI with HDMI cable or the quality of a, once I changed to a mini DP - HDMI cable, see all the problems reported have been resolved.  Thanks for your help.

    First, download and install the drivers from the ATI site, if you have already done so, check the graphics card and cabin temperature by opening. This normally occurs when the temperature is too high. Or if a person has overclocked graphics card.

    In your function mouseDownHandler target you 'e.target.loader', however, e.target is a Loader and Chargers have no property loader.

    Try just "e.target" instead since this should be your code is looking for.

    var my_thumb:Loader = Loader (e.target);

    Although you might find you need to use "e.currentTarget" instead since e.target can point to the content of the loader instead of the charger itself

    Pepper plugins are not used by Firefox.

    This API is for Chrome and Opera browsers, and it should not even appear in a list of Firefox Plugins or the Manager of the Addons > Plugins. It is a 'fault' or a Bug in the installer and must be fixed by Real Networks. My advice is to just ignore it.

    Then use the button Browse... below the text message response area to download the screenshot.

    This Plugin Check page was performed on all browsers of 'service', but has recently Mozilla Firefox only and they cannot switch off analysis for API extensions for other non - Mozilla of. IOW, do not allow a person who uses IE to use the Web page (as I just experienced when I used IE here), but the scan stiil looking for ActiveX and pepper API 'plugins' in the registry?
    Perhaps "other browsers" are disabled temporarily because of the recent eruption of updates Flash and Mozilla blocking the exploited, older versions of Flash, and once things return to normal on this page loads they intend to allow "other browsers" to access this page?

  • Satellite Pro M30 - some mistakes of color and pixel

    The last days I had some problems with the display screen. I had a few mistakes of color-mistakes and pixels. Colors erupt anywhere on the screen, icons disappear and if I move quickly around the screen (with her pinter) ex a document in Word (Office), I have interference with some pixels/points in the text and also a strange thing as some want to erase the text with an eraser.

    But if I have to "Refresh" the sides where it happened that it is ok again, until I repeat once again. I try a few other HD is the same and I also format the HD, but it is still there (I think it might be a virus).

    Also, sometimes the display flashes until it is regular again. Sometimes, it's better or wrong.
    I guess it may be a failure of the map screen. I also get some stick photo (and rehearsals) when I use the cam on Skype & MSN.

    some hint/tip?

    Hello

    May I ask if you have installed another display driver for your laptop? You should only use the display directly from Toshiba drivers because they are pre-tested on the laptop.

    In addition, it would be interesting to know what happens if you connect an external monitor. You may notice the same problem there?
    Maybe reinstalling Windows can also solve this problem

    Anyway, if you need professional assistance, you must contact the service provider authorized in your country. Technicians can check your laptop. :)

  • Pavilion dv6-4024tx: display random crashing after upgrade to Windows 10 (back to Windows 7)

    Hey all,.

    I used to own a computer laptop dv6-4024tx Pavilion which I gave to my father to use after you have bought a new laptop for my part. It was in pretty good condition when I gave it to him, with the only problem being that she would get very hot unless a cooling pad was used (which I it comes with). At the time, it was running Windows 7 Home Premium with no problems and everything was fine. However, it might be interesting to note that while I had it I had problems with random blue screens while I was with the latest graphics drivers, so I drove back to the drivers supplied on the support page for this laptop. After I "upgraded" to Windows 10 (do not perform a clean install) for my dad, the laptop would randomly crash and display something like the photo that I have attached, before going empty and show again several times. Believing that it would be a problem with the GPU, I went and Display Driver Uninstaller to remove completely all AMD drivers and software, downloaded the latest driver on the AMD website and installed. It seemed to temporarily solve the problem, but as it's always within 30 days of installation, I offered to go back to Windows 7, but my father wanted to leave it and see how it happened. Oddly enough, for the next month, it never reported the laptop crashing again and the time period for return finally expired. The problem of course back then I tried the same solution from before but the noise continued. I tried to disable the GPU completely from the Device Manager, so that the laptop was running with Microsoft Basic display adapter. He seems to have stopped the fracas, but less than a week my father told me that he had crashed again.  I tried to restore the laptop to a system image I had done years ago, but I learned that you cannot restore an image to a different version of Windows System. Finally, as a last resort I backed everything up and made a real clean install of Windows 10, and the problem has not yet disappear.

    My goal now is to return the Windows 7 laptop somehow. I can mount a virtual image of the system hard drive and access all the recovery files provided by HP, specifically the Recovery Manager. From there, I can do a recovery USB or DVD (s) we hope to restore the laptop to all conditions of factory (so theoretically return to Windows 7). I will try this, but I need a flash player more than 20 GB or several blank DVDs I don't currently. In addition, Recovery Manager says that this medium can never be created once, so it save me time and money (not to mention my last lifeline) if someone could please share their views on the question of whether this method would be successful or not. I know in case it doesn't work, there is always the question of registration of the OS by Microsoft, but I can cross that bridge when I get to it.

    Sorry for the essay I just wrote, but this has been a problem for too long, and I am at a loss to know what to do now (apart from the purchase of another computer). If there are any questions I'll be happy to answer, and I hope we can get this issue is resolved. See you soon.

    If you follow this step 3.

    You will need to select "format and repartition disks" as windows 10 will have changed partitions.

  • Changing the settings to display randomly - 1152 x 864 resolution changes randomly to 1024 x 768

    At seemingly random times, the display settings change of 1152 X 864 pixels, I put it to 1024 X 768, that moves a lot of icons.  I then have to go to customization - display back change and move icons where I want that they on the desktop.  It's very annoying.  I have a Gateway computer and have seen similar complaints from Dell and HP users.

    Hello

    I would suggest trying the following methods and check if it helps.

    Method 1:

    Try to check and clean boot if this can help.

    How to solve problems using the clean boot in Windows 7: http://support.Microsoft.com/kb/929135  
    Note: once the diagnosis has been made, make sure that you try to step 7 of the article to reset the computer as usual.

    Method 2:

    Run the scan of auditor of file system (CFS) and check if it helps.

    How to use the tool File Checker system to troubleshoot missing or corrupted on Windows 7 system files: http://support.microsoft.com/kb/929833

    Note: this will help you to replace the system file that is causing the problem.

  • Given that you have blocked Adobe Flash and I uninstalled as suggested by many commentators, what are my options to see the content I want to see?

    Yet once, now that Adobe's Flash problems are everywhere the news what are my options to display the content on the sites that were previously used by Adobe Flash? I uninstalled Adobe Flash, but need an alternative. Thank you!!!

    Mozilla had 'soft-blocked' version 18.0.0.203 and earlier, which still allowed you will activate Flash on websites of that trust.

    If you are not accustomed to using the "Request to activate" feature with any of your plugins, here's what to expect:

    When you visit a site that wants to use the Flash, you should see a notification in the address bar icon and one of the following: a link in a black rectangle in the page or an information bar slides between the toolbar and in the page area.

    If you see a good reason to use Flash, and the site looks trustworthy, you can go ahead and click on the Lego-like icon in the address bar to allow Flash.

    But some pages use Flash only for tracking or play ads, so if you do not see an immediate need for Flash, feel free to ignore the notification. It will just sit there in case you later want.

    Until this ordeal of previously unknown security flaws shakes, you might want to try this and see how it fits. To set the Flash "Ask to activate", after you have reinstalled it, open the page modules using either:

    • CTRL + SHIFT + a
    • "3-bar" menu button (or tools) > Add-ons

    In the left column, click on Plugins. Search 'Shockwave Flash' and always change 'enable' to 'ask to activate '.

  • Cropping at random Flash

    Help, all the flash videos are cropping at random. Also, when I go fullscreen, video does not fill the entire as screen it used to. I still see the black frame on all sides. It happens only on Firefox. I tried to uninstall flash and firefox and then put it back, but neither solves the problem. It's not just YouTube, it happens on blip too. You can see the black bands move as it tries to reframe random videos. I think it is purely a matter of Firefox because I tried the same videos on Google chrome and did not encounter the same problem.

    You can try to disable hardware acceleration in Firefox.

    • Tools > Options > advanced > General > Browsing: "use hardware acceleration when available.

    You will need to close and restart Firefox after enabling/disabling this setting.

    You can check for problems with the current versions of the plugin Shockwave Flash and try this:

    Hello!

    Immediately after the Update Beta 34.0, Silverlight and Flash, completely stopped working in Firefox. I am running Vista Home Premium, Service Pack 2.

    They work fine in Internet Explorer.

    This happens in any website I want.

    For example, I can go on Youtube and the page will display a black box where the video should be, but there is no control of playback, or any way to activate the video. Clicking in the black box has no effect.

    On the site of game music, Grooveshark, the site does not recognize Flash installed at all. (If you have not installed Flash, this site displays a message each time. Grooveshark correctly recognizes that Flash has been installed by Internet Explorer.)

    I've updated the Flash plugin for the current version, which also has nothing.

    I have not reinstalled Firefox, or do a system restore, still.

    I just bought a new computer I was going to migrate to and withdraw from this computer, so I wasn't going to make heroic efforts to solve this problem. I reported this more on the order of a bug report.

    Karl,

    Do you by chance have Flashblock installed? I had checked before and did turn off but it seems was not enough. Update b 34, 1 break Flashblock who, in turn, breaks Flash and, for me, VLC. I had to disable (in Add-ons) and restart Firefox, and now everything is fine.
