    Wallpaper quality loss when seting as background


    Ive saw the diffreences while setting my old high quality wallpapers (1920x 1200) as background.Being used with the same wallpapers for some long I instanly noticed the differences.
    I have the latest drivers

    so here is a capture while runing winodows 7:

    I'm seeing the same problem here. Have you found anything new about this issue?

    I'm on a new build with windows 8 but I'm using the same graphics card that was in my system when I was using windows 7 and I know it never happened on windows 7. It has nothing to do with the quality of the wallpaper as when I view the wallpapers in windows photo viewer at the correct aspect ratio there is no quality loss or distortion. It happens even with the default windows 8 (daisy?) wallpaper. I notice we both are using nvidia graphics cards...I'm on 306.97 drivers. I'm going to boot up my system using the intel HD 4000 graphics provided by the CPU tonight and see what happens. I'll report back what I find.

    Both images that I've posted below are on windows 8 so don't be fooled. I grabbed the windows 7 wallpaper and there is obvious distortions and "blurryness". I've circled the worst areas in red. If you view these in full screen you can see it pretty clearly.

    I've been doing some testing. As far as I can tell it has nothing to do with the graphics card or drivers. It happens even with the intel HD 4000 graphics. I resized the wallpaper to my desktop resolution and that didn't help the situation. I then saved the JPEG as a BMP and that didn't help. I saved it as a PNG and the problem went away!

    So it appears that windows 8 is compressing the wallpaper for BMPs and JPEGs. It has nothing to do with the size of the wallpaper (of course this only applies when the wallpaper is larger than the screen resolution and it doesn't get stretched to fit on the entire screen). Not sure which other file formats get compressed by PNGs work fine. This is very annoying...wish it was the same as windows 7. Anyways looks like a "quick" fix is to just run all your wallpapers through a batch converter from JPEG/BMP to PNG. Although JPEG was nice because the file sizes were small compared to PNG sigh!

    EDIT: Seems as though others have been talking about this too. Kinda confirms what I found.

    I've looked around pretty extensively and can't find a decent fix and others are complaining of the same problem. I just batch converted all my wallpapers to PNG using Irfanview and the problem is solved. However before the batch convert I noticed that some of my JPEG wallpapers wouldn't lose quality as much as others when set as wallpaper...anyways converting all my wallpapers (310 of them) only took about 5 mins.

    Here is the difference when using PNG file format (keep in mind that these were both originally JPEG images). Sorry I had to crop the first one so that it was within the 2mb limit. You can call me picky but the difference is pretty huge I reckon. Look around the windows logo and see how clear it is compared to my first post.

    Yup it has nothing to do with Nvidia graphics. Ive changed the original post if you could see but the title doesnt want to change btw.

    and yes some wallpapers do not loose that much quality while being set as backgrounds.

    And your quick solution worked.

    Ive saved the file as PNG through Photoshop and it twice in size. It looks I will need to double my space for my picture folder. However my wallpapers are bigger than my actual display resolution 1920x1200 to 1680x1050. If I reduce their size to my display resolution do I loose any quality in displaying them?

    Do you think there are any quality differences when using a converter or another or just save those pictures as PNG from an editing program like Photoshop?

    How do I solve this loss in case of themes not just wallpapers ?


    Anyway Im so gratefull to you. I was about to reinstall my windows 7. This was the last straw for me after other incomodities with windows 8.

    What program do you use to have that sweet white start button ????


    I would call this partially solved. The theme wallpaper quality preservation remain in doubt tough

    If a moderator/ administrator could edit the thread title the way I modified it in the original post and to move the whole thread to customization since its proven its not a graphic card issue.

    I stronlgy recommend an administrator to put this as an Important announcement somewhere to be broadly visible.Its about Windows 8 dealing with non PNG wallpaers

    Interesting!

    I've noticed something:
    - you both have large resolutions (1080p and 1050p)
    - geforce 560 and 660
    - and you both have the same problem
    - what monitors? hmmm....

    Try a lower resolution just for testing, then you can switch back.
    Do a 800x600 and 1024x768 just to see if JPG is displayed better.

    I don't know how many people are suffering from this but not so many I guess.
    It must be the hardware + drivers combinations on Win8 that makes this happen.

    I'm pretty sure you're both on LCD's (who's using CRT anyway?) and you'll normally need 60Hz so make sure it's 60Hz.

    If you, by any chance, reinstall Nvidia drivers, remove older settings and restore defaults.
    Run without gfx overclocking just to see if that causes the problem or not.

    IMPORTANT:
    One last thing: check for any extra (ICC) color profiles that may be required for your monitor.
    This seems to be helping some people around here (I've seen that in an older thread but don't have the link).

    @Pauloz1890:
    Acer Monitor here:
    Acer Support: Downloads & Support Documents - Monitor / G Series / G245H

    Get the monitor driver, install it. Look for the .icm file and install it as well.
    Then restart and see if it helped.

    @StefaNafetS
    Try something similar but for your monitor, didn't see it in the specs to see it some profiles exist for it, but I think you'll manage that yourself.

    Good luck to you all.

    Well isnt just us and im sure this is a common issue bot others dont give a**** about it lol
    And nope, lowering the resolution does not have any effect besides lowering the resolution ))
    I have 60 Hz rferesh rate.
    And its not Nvidia. Ive done several clean installs of Nvidia drivers, kept them default but its not this. I can confirm that is windows 8 causing this because :

    Ive forgot to mention that Ive reinstalled my windows 7 and the wallappers are displayed corectly.


    My monitor is a Packard Bell Maestro 220 WDV. Its not on sale anymore. At least I cant see my model on their page.

    Try this one:
    http://global-download.packardbell.c...ll&SC=EMEA_13P
    I already searched the best matching one (Maestro 223) and this zip is for x64 Vista.
    You will find the ICM file which is needed to be installed.
