  • zBook 14 - cannot change the resolution of the screen after update

    After I installed software updates the portable suggested to me, my screen resolution went suddenly from 1900 x 1200 at 1200 x 720 after reboot and it won't let me change it, not even to a lower resolution. I'm very frustrated, because I need the computer week next for visualization work and I really need the screen works well.

    It doesn't let me change the resolution. Graphics and display drivers are up-to-date and functioning according to Device Manager. I did a system restore, but that just do everything worse although the resolution worked once again thing, I had to run a repair of the start several times before that my laptop would be starting another property again. This does not resolve the issue, given that the display drivers are not working properly (videos have been viewed very badly) and even after updating the computer won't start again, so I had made another system of recovery and now I'm to the point where I can not change the resolution and starting to be really frustrating. Also, (if it even starts) Windows is constantly freezing, forcing me to hard reboot.

    Thanks for any help, that all the world can offer.

    This looks like a lot of problems, you have there.

    First thing I would say is to do a check of the basic material. Your laptop will be built Diagnostics the F2 button on the HP logo. The hard drive on a test extended (approximately 45 minutes - 2 hours) and the memory test. If these two go, consider downloading of UEFI diagnoses from the above drivers download section. In all honestly, I think this unnecessary step for most, it tells not usually defects that are already not obvious. But he should have a graphics test, if it will throw a failure even if it is faulty is another matter but when even, of a value of a test.
    If all else fails, download on the phone for the HP warranty.

    If anything fails, run the memory on memtest86 + for about 12 to 24 hours. Download you, it's free, burn it to a cd and the start of it. And it works simply, in case of error, you have a fault memory.

    If anything fails on any diags, then nothing is most likely false, cool reimageries windows probably will solve the problem and its probably just a form of spyware or corruption of driver or something. Backup your data, reinstall a new copy of windows.

    But in my experience, from doubtful, repairs etc... freezing randomly and other problems are often a sign of a failing hard drive. And diagnostic tests are not always 100% to pick up a failing drive. For the most part, but not always. So, if its still high reading after a reimage, review the reader always a potential source of the problem.

    To the extent where it won't let you change the resolution? What you mean? As for the option is grayed out? Can you maybe post a screenshot and a screenshot of your device with the extended graphics card Manager.

  • Change the resolution of normal-vista through Safe mode-vista

    Hello!

    I installed a demo version of this game of strategy, 'Starcraft 2 '. After installation, I try to play. However, without warning the game changes permanently my screen resolution to a value that is compatible with my monitor (says my Samsung TV/Pc monitor ~ "cannot display resolution")

    Even after restarting Vista, remains the problem of resolution. Still no display.

    Vista safe mode, but displays in another resolution and works very well (I am writing this message in SafeMode). Now, I can change the resolution here, but whatever the changes I make do not transfer to normal-Vista mode.

    If anyone, please tell me, How to change the display resolution of the normal mode, safe mode? Alternatively, how can I change the resolution, 'the eyes bandaged?

    I uninstalled and will avoid the game.

    I also tried the system restore, twice in fact, just to be sure. Picked dates from before I even heard of the release of the demo, but it still does not work. The display resolution is still off enough to leave my empty screen.

    Try the following, but do it in Safe Mode so that you can see everything on the screen...

    1. set DPI:
    Right-click on a free space of the desktop > customize > column to the left, adjust the size of police (in PPP) > uac prompt > click default scale (96 DPI).

    2. resolution:
    Right-click on a free space of the desktop > Personalize > Display Setings > move the slider to the right or left whatever the case may be. Check your user manual, see if she tells you what resolution is for your computer. My laptop is using 1280 x 800 pixels.

    Here is a table of the guide line:

    Monitor 15 inch

    1024 × 768

    17 to 19 inch monitor

    1280 × 1024

    monitor 20 inch and liked

    1600 × 1200

  • Updates change the resolution

    The last two times that installed Windows automatic updates, the next time I used the computer, the resolution was changed to one that is less than the optimum for Windows Vista.  I did a system restore every time to solve the problem, because it was easier than trying to figure out how to reset the resolution.  Why do auto update change my resolution?

    To change your display resolution:

    1. right click on the desktop and select "personalize".

    2. click on "Display settings" at the bottom.

    3. in the window that appears, move the slider to change your resolution. If you don't know what you want, try to drag the increment of a cursor at a time and by clicking on 'Apply' at the bottom to try the resolution. Note: If you change the resolution to one that is not supported by your monitor and your screen becomes black or displays an error message, DO NOT PRESS ANYTHING! Wait 15 to 20 seconds and the display will return to a compatible resolution.

    Now that you know how to change your resolution, you can feel free to install updates in the future.

    Hope this fixes your problems,

    Rifdhan

    Change the screen resolution

    Screen resolution refers to the clarity of the text and images on your screen. At higher resolutions, items appear sharper. They appear also smaller, so more items adapted to the screen. At lower resolutions, fewer items adapted to the screen, but they are larger and easier to see. At very low resolutions, however, images may have serrated edges.

    See you soon.

  • Photoshop, change the resolution of the screen on startup

    Hi all

    I'm working on a new Dell XPS 15 laptop computer. All the drivers are up to date. I tried to reinstall the Psalm

    Everytime I open Photoshop the screenresolution is automatically changed to 2560 x 1440 to 1920 x 1080 and I get an Error Message in the background (the operating system is not configured for this application). I can manually return and continue working. But next time ill start it happens everywhere. It's a little boring. All other Adobe applications seem to work well.

    Thanks for help.

    Photoshop cannot normally change your screen resolution, but there are applications that can be configured to change the resolution as launching an application. On Windows when an application is run in compatibility mode possible of put so the resolution also changes. Click right photoshop.exe, select Properties, compatibility and check any of the boxes of resolution are verified. I'd watch if there is a utility on your Dell running in the background designed to change the resolution.

    I took a glance at your laptop and its native resolution is 3840 x 2160, No 2560 x 1440 except that varies from a model. It is worth noting is 3840 x 2160 (1920 x 2) x (1080 x 2) and you get the half that is 1920 x 1080. This could suggest that you set Photoshop to the scale of the display. Make sure that the parameters of scaling in your preferences are fixed to 100%

    Hope that helps

  • How to change the resolution of the After Effects project rendered in Adobe Media Encoder for an overview of H264?

    I want to make a 1080i computer at half the resolution or third resolution in the SOUL to speed up rendering for previews times low resolution. I just got a glimpse of H264 low-resolution take 5 minutes to encode in AE and 28 minutes in the SOUL.

    It's easy to do in After Effects rendering parameters. However, the option "video" in the SOUL seems to imply that is encoded at this resolution, not made at home.

    I went into AE and changed the setting in the composition to "half" window, but when I queue it in the SOUL, the 'Source Match' button still shows 1080.

    What is the right method to get the results I want?

    I am currently using AE CC and CC SOUL on Windows.

    Short answer: the feature you are looking for does not currently exist in the After effects-of-SOUL workflow.

    When the SOUL is coding a mock-up of After Effects, it doesn't have the ability to affect the way in which the model of After Effects is rendered. The model will be always made its intrinsic properties. Even when you resize the encoding settings in the SOUL, the full model is made and scaling only during encoding.

    Caution: SOUL CS6, we began work to enable this feature to exist. When you right-click on a computer in the queue of the SOUL and click the Source settings, you can control the rendering of After Effects settings: Guide layers are visible or not. Our intention is to extend this feature, although the addition of parameters affecting the properties of the model (as opposed to the visibility of the layers) is much more difficult and remains on our to-do list.

    In addition, the composition Viewer settings do not affect the properties inherent in the model itself, it only affects the way in which the model is seen.

    As you correctly deducted the differences between rendering and encoding, I expect you have also already considered workarounds to get what you want (a model made faster which is coded in the SOUL), but summarize these ideas even when:

    (1) makes an intermediate file without loss of After Effects and which encodes your delivery with SOUL format, possibly using spyware files to automate the side of the SOUL of the process which is what I would recommend.

    (2) nest your scale model in a model more small that corresponds to your desired settings and encode this model in the SOUL.

    As always, please send us your thoughts on how you want to see the After effects-of-SOUL improved workflow: http://adobe.ly/feature_request

  • 4 K TV can not change the resolution or refresh rate

    When I connect my end of 2013 retina MacBook Pro to a TV 1080 p via HDMI, system preferences port gives me a list of supported resolutions and refresh rate to choose. But when I connect to the laptop even to my new Vizio M43 - C1, it generates a fixed 3840x2160@30Hz and gives me only a handful of options for scaling HiDPI. I want to change frequency to 24 Hz for movies, I do all the time with TVs 1080 p, but I can't find the option anywhere. SwitchResX works, but are there seriously no official way to change the resolution and refresh rate when a 4K TV is connected? Looks like a massive oversight.

    Hello NeilT6,

    These 4 k TVs sound incredible. If I had one I would like to than the best resolution, that I could not too.  Have you tried now hold Option key while selecting the display scaling settings?

    Use screens 4 K and Ultra HD TVs with your Mac - Apple Support

    Pointing your mouse on a resolution options will show more details about this option. To get a button detect displays appear, press the Option key. To see all available resolutions, press Option key while clicking on the button of the chipped.

    Take care.

  • Change the resolution of a project in iMovie 10.1

    Hello

    I'm doing a movie with iMovie 10.1 and for some reason any iMovie set my project at 4 K resolution, but I only need 720 p. Is it possible that I can change the resolution of the project? In the project settings, it shows the 4K, but I don't see an option where I change.

    Thanks for your answers...

    A draft resolution is defined by the first clip that you put in the timeline.  Create a new project, then put a 720 p clip in the timeline panel.  After that copy and paste all the old project into the new.  You can now delete the first clip if you wish.
