Acer AL1916W suddenly showing is not the correct resolution.

Today, I restarted my mac mini Yosemite running.

Now my screen resolution is messed up.

I have a choice of 1280 x 1024 or 800 x 600, but this monitor, an Acer AL1916W needs 1440 x 900.

It has worked well for over a year, but only with this reboot, it doesn't work.

I thought that maybe the driver suddenly disappeared, but I can't find a driver for this mac.

I tried a second restart, that didn't change things. Then I'll do a full reboot, but after that, I'm stumped.

OK with a full reboot, the resolution is restored.

Probably should have tried that before posting, but at least it is here if anyone has the same problem.

  • Maps Google widget shows is not the correct location in Muse [edited: Google maps for United Kingdom?]

    I think that there is a bug with the Google Map widget.

    I followed the instructions to insert a Google map into my Muse page, but all I get is a map of the world.

    The address I've tried to get is: 100 Station Street, Burton on Trent, Derbyshire, United Kingdom, 14 1BT (restaurant name omitted as long as it is not officially open yet)

    I see a "sign in" on the map and as I already have a Google identity I could connect if given option.

    Hi William,.

    The correct addresses for your location was detected by Google as - 100 Station St, Burton-on-Trent, Staffordshire 14 1BT, UK,

    Please try with this and it will work,

    Kind regards

  • Index is not showing is not the correct page numbers

    I use 7 HR to develop versions online and print the user guide. There are several tables of contents for this project (the tables are specific to the user). When I generate the project for my chosen table of content, and I find the results, the index numbers do not show the right page. Example: number of units... 106; number of units is actually on page 112.

    Is there a trick to make it display correctly?

    Thanks in advance!

  • Keyboard is not showing is not the correct characters on Windows 8.1

    Hi all, I have the model of keyboards two HP 5188-6077 and on Windows 8.1 capitalized 2 which should be the @ key is entered the "symbol and vice versa the" key gives the symbol @. I have never used these before on Win 8 keyboards, and they both do the same thing, so I think it's a driver problem. They both type correctly on Windows 7.

    I tried, but could not find the right driver for 8.1. Someone at - it a solution? Thanks, Jim

    Hello

    It sounds like the region of incorrect entry for keyboard - if the @ is above the 2 it must be set up by US (the "above the 2 is UK).  See the guide below.

  • Overview of Muse is not showing is not the correct fonts

    I am currently in the middle of building a site of fluid layout to Muse a typekit (Futura PT) font and until today, in Muse preview mode showed the site because I've been designing.

    I launched the site yesterday (www.weare-awesome.co.uk) howeverneeded to do some bug fixes. When I went back to the file in Muse, I've changed some things, went to listen to samples and the text had default Helvetica/Arial in this mode. I did a publication and online site shows Futura...

    It's really weird, however more so impractical to have a preview (offline) mode which is not displayed as expected because I need to test before you publish the modified changes.

    Can someone tell what is happening?

  • Error: It's not the correct recovery disks.

    I replace the hard drive in the pavilion a6432f pc desktop by using the recovery cd and keep the error message: these are not the correct recovery disks. Ive checked that the AUCTION # s match of the cd recovery with SUBMISSION # on the bottom of my pc. The only option Ive been able to find online is also install another operating system.

     

    I have a problem with that. The only other operating system, I have Windows XP and the pavilion a6432f supports Windows Vista, so there is no drivers for some of the critical components of the system.

     

    Y at - there someone who can help me with this problem. I have not either the option of performing from the hard drive. The previous hard drive has failed and been replaced since the mfg'r. That's why I'm using the recovery cd

    It is usually a problem with the BIOS that is causing the problem.  Recovery checks the BIOS to determine the model and other info before it will install to prevent recovery used on discs machine no HP or on the wrong model of HP machine.

    It usually takes HP service to insert the correct information in the BIOS.

    Have you ever used before recovery disks?

    Any material changes other than the new HDD machine?

    Windows 7 would be a nice update to the machine. Win 7 has an abundance of builtin driver support, and if necessary most Vista drivers work in Windows 7.

  • Windows 7 sees my second monitor as "generic non - PnP" and will not let me set the correct resolution

    Hello

    I just installed Windows 7 Professional 64 bit on a new hard drive on my Dell Studio 540. The PC has a graphics card ATI Radeon HD 3450 and has a Samsung 226bw 22 "monitor on the digital output. This works very well, and has the resolution of 1650 x 4050. When I am running Vista (on the previous hard drive), I got a monitor flat 14 "old on the other out, and it worked fine (although at a lower resolution).

    I added a monitor AOC F22s + on the other output, expecting to be able to put this to the recommended 1920 x 1080 resolution. Unfortunately, Windows has developed the driver for this monitor "Generic non - PnP" and will not let me set the correct resolution. To the maximum it will allow is 1600 x 1200, (as well as all other resolutions it allows) do not use the monitor at maximum capacity, which is the ratio of evil anyway, so the display seems tense.

    I run Windows Update, so have the latest drivers. I tried to install the other drivers, but nothing helped.

    I tried to unplug the Samsung monitor and restart the PC, so that the AOC, one was the only monitor it and he always had as 'Generic non - PnP' with the wrong resolution.

    Someone at - it ideas? I'm at my wits end. AOC support did not understand and could only suggest that the monitor was faulty, but the place where I bought it insist that it works very well and so no Exchange or get a refund (no restocking fee, which is a RIP-OFF).

    I really want to use both screens and would appreciate greatly any help that anyone can give. I hope I gave enough information. If I didn't, please let me know.

    Thanks in advance,

    Alan

  • Windows Genuine Advantage problem, says this is not the correct version

    I am trying to download windows DVD maker or windows 7, but I came across some very irritating errors and I am very angry and annoyed.

    The first problem is, the "Windows Genuine Advantage tool" said that it is not the correct version, even though it has been downloaded from the microsoft Web site, photo of the error is here: http://imageshack.us/photo/my-images/818/wgaerror.png/
    My data from the computer (operating system, etc.): http://imageshack.us/photo/my-images/688/pcinfoc.png/
    I also ran the "Windows Genuine Advantage Diagnostic tool', here are the results: http://www.mediafire.com/?99vwm612pmvvkmd
    The second problem is, I tried to run the "Windows Genuine Advantage tool' through control ActiveX in Internet Explorer 9, but after I clicked to install the"Windows Genuine Advantage tool', nothing happened.
    Thanks for posting a solution as soon as POSSIBLE

    You MUST use Internet Explorer for any process involving the Validation.

    You'll be rewuired first to install an ActiveX control, and in the case of wof Windows 7, Windows Activation Technologies update (if not already installed).

    Once they are properly installed, then the system should automatically refresh the page, and the continue button should implement a download button.

    Note that the use of some security software or settings may mean that the serveer is unable to work that your operating system and the browser is really - with the results that it tries to treat IE9 on Win7 as FireFox on XP - with the results you see.

  • presentation is not showing is not the projector

    I am a teacher. I use keynote to give the notes/lecture to my students. Today, after having finished class I escaped to my presentation and made preparations to restart. When I hit 'play', the presenter appeared on my MacBook Pro retina (as it does in general) and had no problems coming on my iPad. but he kept on my projector showing my office. I escaped and tried again, same thing. I unplugged my thunderbolt port projector cable then rep notched in: same result. I have mirrored display of the mbp and projector. Came on the MBP and not the projector. I tried to leave the program, which took time. When I re-opened, the main screen has become transparent. I then leave off of it and restarted the computer. This solves the problem, but after my next presentation, it's the same thing. I ran a scan of disk utility, and it says everything is fine. I am running the latest version of El Cap, in fact I've just updated last night. Could the update be the cause? Also, while this was happening, I was unable to restart or shut down the computer. I had to make a hard stop down by pressing the power button and hold. Ideas?

    Try to reset the Keynote, perform all the steps in the order listed

    Keynote, you must use a request to work procedure removal tool uninstall

    AppCleaner is free and works well for this procedure, it can be download here: Appcleaner

    • uninstall the Keynote with a removal tool
    • empty the trash
    • Shut Down the Mac (Apple menu > turn off)
    • Wait 10 seconds, then press the power button
    • as soon as you hear the startup tone, hold down the SHIFT key
    • release the SHIFT key when you see the gray Apple screen, start-up will take a few minutes longer than usual as the Mac performs a software repair
    • After the repair and the Mac is completely started, restart the Mac normally (Apple > restart)
    • install Keynote from the Mac App Store

    Hello

    I have a producer consumer with a queue architecture to pass values. I want to push a new value in the table by using "Insert table" when a button is pressed, but when I do the previous value is read the first time and the correct value on the second press.

    I am self-taught and this is my first time using the queue so maybe something I'm not seeing/thinking about here?

    Version 8 attached VI.

    To see the problem, follow these steps:

    1. run
    2. click on "master reading.
    3. change the 'value '.
    4. click on "master reading.
    5. click on "master reading.

    Any help is appreciated especially block critical diagram.

    Thank you!

    It all depends on how you change the value of 'value. ' If you use the increment and decrement buttons it works as expected.

    If however, you type a new value and click the button without clicking elsewhere first, it does not - and here's why:

    When you type a modified value value does not appear in the code until the control loses "touch focus". The problem is that clicking the button causes the digital input to lose key focus, but only after the code responded to the mouse event.

    To solve the problem put a property node in the supported mouse event to set the property KeyFocus the digital to false until the value is queued.

  • Satellite C870 - 19L can not set the correct resolution

    I have a new laptop and my problem is that the maximum resolution that can be adjusted is 1366 x 768, although the screen has a resolution of 1600 x 900. The problem is, that only 80% of the desktop is displayed, the area to the right is not displayed.

    I couldn't find an .inf file in the download section.

    What can I do?

    In Notepad, specification is clearly written that your laptop comes with preinstalled Win8 64 bit and this preinstalled OS (recovery image) contains the right display driver. Default factory settings resolution must be set to the native display resolution.

    The question is: you use this original preinstalled operating system and if not what exactly do you do?
