Poor resolution in linux

hi...
i find that the resolution of movies played thru jmf is poor in linux as compared to that in windows. Anyone knows why? can anyone suggest how to improve it?
Thanks and regards...

Maybe Windows has better graphics drivers supported by the graphics card manufacturer directly.
Or more simply... your fault...
You may have different graphics mode settings for the screen size, number of
colours and screen refresh frequency.
regards,
Owen

  • Poor resolution connecting my MBP to TV via HDMI. visable vertical lines.

    hey!
    so I've been googeling around for awhile and it seems A LOT of people have this issue. but I haven't been able to find a solution yet. Story goes... connecting the MBP to the TV via DVI to HDMI gives poor resolution. the weird thing is this only happens every other time. I've tried it on my macbook pro (2007) and another macbook (2010) and it has the same issue with both (but only sometimes). any thoughts?
    thanks!

    To Csound's good advice, let me just add that there may be a specific HDMI port on the TV that you must use if you're going to send audio to the TV separately. This should also be explained in the TV's manual.

  • I have a desktop iMac,within a yr old, I had iPhoto 9,downloaded to iPhoto 11, now lost my export to Shutterfly link, & looks like all my photos went to thumbnails, with poor resolution...help!!

    I have a desktop iMac OSX 10.6.8, had iPhoto 9 & downloading software update to iPhoto 11, (9.1.5??) I can't find the way to reset up the "Export to Shutterfly mode" and it looks like all my previous photos went to a thumbnail size...with now poor resolution. If I would have know my pictures were going to turn into poor quality pictures, I never would have done the software update.  Need a real person to talk to. This complicated method is not user friendly.

  • Poor resolution after importing to iMovie 10

    I've just upgraded to iMovie 10 and Mavericks from 9 and my old clips are now displaying with what appears to be a poor resolution. When I watch them in 9 they look much richer.....thoughts?

    i am having the same issue. tried "adjust colors" in the video FX and the preview looked great, but application of the effect left the clip unchanged.
    did you get any help from another source (since this seems to be without responses)?

  • Poor resolution on playback of PNG slides

    I'm making a video presentation consisting of *.MOD segments and PowerPoint slides that have been converted as 25-90 KB *.PNG slides.  I burn the DVD. On playing the DVD on TV,  the slides have very poor resolution. What am I doing wrong? Thanks for any help you can give.

    Welcome to the forum.
    What are the pixel x pixel dimensions of those PNG images. File size does not really mean anything in video.
    What is your Project's Frame Size in pixels, say 1920 x 1080?
    Exactly how did you convert the PowerPoint "slides" to PNG?
    Good luck, and please let us know a bit more.

  • Poor resolution on iPhoto book

    I just ordered the large softbound iPhoto Book from Apple and am very disappointed with the poor resolution of the photos. My original files were 1280x960. Is there any way to find out if my photos are being uploaded at the highest possible res? I've read other posts about changing preferences, but haven't been able to figure out how to do that at my end.
    Thanks!

    Emily:
    The easiest way I've found to modify preference files is with Pref Setter. Once you've located and opened the iPhoto preference file do a search for "dpi". Then change the values for the Keys BookTargetImageDIP, BookTargetSmallImageDIP and BookTargetMediumImageDIP to 300. Save and close Pref Setter. That's it.
    It's interesting that you found the large book images to be poor. There was another user that received large books from both the east and west coasts. He found the east coast book to be of lower image resolution (greater halftone pattern) than that from the west coast. All of my large size books have come from the west coast and have been very good, with or without the resolution change in the preference file. Not so with the medium size books. There were patterned no matter what resolution was set in the preferences.
    Good luck.

    Yes, on the right side of the U.K. Apple Store homepage there will be an "Education Store." You can get something like 10% off, it seems.

  • Poor resolution of dektop after nvidia driver update

    Hi,
    I have a HP Pavilion Media center 8020n PC connected to HP w1907 monitor with optimum resolution of 1440X900 at 60 hz.
    The display adapter is Nvidia GE force 7350 LE. It has Windows vista home premium with Intel Core 2 processor.
    I recently updated the video driver from nvidia website version 266.58. Right after the download at the first bootup there was a big difference in the screen resolution. The picture is not crisp and sharp like it was before the update.
    I have tried to uninstall the new driver, unnstall the old driver and restart in safe mode with the antivirus off but it still gives the same poor resolution with streched out picture.
    Any suggestions?

    Hi,
    Look here for a monitor driver update.  Install the driver and reboot. Then check the monitor type in the Device Manager. Now does it indicate the HP 1907 monitor?

  • PBS viewing poor resolution!

    PBS viewing is  very poor resolution. AppleTV connected via ethernet. Tested Internet speed while viewing AppleTV 18.16 MB/sec. which tells me it is PBS service. I have also noticed more and more of this with NetFlix

  • Screen turns black and returns with an orange tinted window with poor resolution

    Im running on a Presario S6700NX. Windows-xp It has been running proper until about two weeks ago. Nothing has been added or taken from the system. However, lately I've been getting a black screen that last several seconds and when my window reappears however, It's with an orange tint and with very poor resolution. Several seconds later my window reappears with the proper resolution. This happens whether I'm running an application or not and it's continuous. I've searched microsoft knowledge base and I've gotten no response it's as if it's never happened to anyone else. So now I'm trying HP Forum in the hopes that someone out there may have encountered a similar problem or has heard of a simular situation. This is a cry for HELP. Please if anyone out there can help me it would be deeply appreciated. I want to give my thank you beforehand and hope for a response.

    @jck & @awaller well not literally every other time, it occurs randomly. sometimes I can work for like an hour or as long as I want and nothing happens, sometimes after 5 minutes *boom* the screen goes black, except of one column with random pixels, i tried to switch to a different console with ctrl+alt+(F1-F6) but it did not work...
    do you know where I have to look for errors? I also tried to reinstall the drivers, but it did not help..
    I see something like this on my T420 Thinkpad sometimes. It turns out the backlight is just going out. I'm reluctant to say it's a kernel issue and not hardware - I have vague memories of it happening on Windows 7 as well, but that was years ago ...
    It happens on Arch and Debian definitely, and the following fix works on both for me:
    Opening a terminal (which I have bound to a key) and running "xset dpms force off", then moving the mouse or something to wake the display again brings it back to light.
    Try that the next time it happens and see if it helps. Will at least confirm whether it's the same issue as me or not.

  • Poor resolution from mini-vga to s-video adapter

    I recently bought a digital projector to watch movies on at home, and am using my 14"iBook as the video source. It works great when using a vga cable. However, i want to run the cables up through the ceiling and down through the wall to keep them out of sight. I had read that S-video was supposed to be a fairly high resolution method of transmitting the signal, and is also a lot slimmer than vga (and thus easier to snake through the walls.) So I bought a mini vga to s-video/ video adapter and when I hook it up to the projector, the image quality is very poor. Is there a setting that needs to be changed on my iBook to get it to display properly, or something else that I'm missing? I bought the adapter used on ebay, so I'm trying to troubleshoot the problem without buying another adapter only to find out that it still doesn't work. Also, I am running screen spanning doctor, but even if I change to mirror mode, it still looks bad.

    Thanks for taking the time to reply, John. That was my suspicion. Guess I'll have to drill giant holes to be able to run the VGA cable. Unless of course I could figure out how to remove/re-attach the connector end. Anyone know if this is possible? Or, is it possible to find a 15' long mini vga? It seems that there ought to be someone out there who could make custom cables for unique situations and needs like mine. What I really need is a box that runs off my ibook that has multiple display outputs so that i don't have to pull cords every time I want to switch from my 22" widescreen to my projector.

  • Workaround for slow performance and poor resolution with RED R3D files in After Effects CC 2014 (13.0)

    http://blogs.adobe.com/aftereffects/2014/06/red-r3d-problems-after-effects-cc-2014-13-0.ht ml
    The After Effects team are investigating a bug in After Effects CC 2104 (13.0) where RED (.R3D) files are very slow and the image resolution is poor, about 1/8 sampling.
    The following workaround has been reported to solve the problems in some cases:
    Save the project.
    Choose Edit > Purge > All Memory & Disk Cache.
    Please post in this thread about whether or not this workaround helped you.

    Intentionally cross-linking threads: this issue was first reported in this thread, which has an ongoing discussion:
    AE 2014CC RED R3D files support broken - footages looks bad, everything slow.
    The thread you are in now is the comment thread for the blog post. Please post in whichever thread makes more sense for you. I am monitoring both.

  • Importing pics from a friend's Facebook album - poor resolution

    I am making a photo book in iPhoto and am saving pictures from a Facebook albums ... but resolution is too poor to use. Any suggestions??

    Only one. Don't use photos from facebook albums. When a pic is uploaded to Facebook it is "processed", which means almost all the metadata is stripped away and it is heavily compressed. Simply, they are such poor quality that they won't print well.

  • Poor resolution of slide show on CD

    Created slide show in Photoshop Elements 5.0 and burned to CD.  Resolution was poor and it did not play in a DVD player.  Sales person insisted bundle of Photoshop Elements 8.0 and Premier 8 would allow me to create a DVD.  Tried editing my Elements 8.0 slideshow in Premiere.  Playback "stuck" and resolution poor.  Saw forum where I should  "render" the slide show.  My 10 minute slide show took 6 1/2 hours to render and then the whole thing crashed and it still isn't rendered.  Decided to try building the slide show in Premiere.  Cannot sync my music to the slide show (so it all ends at the same time) and have found nothing to tell me how.  Decided to go back and try to burn the CD in Photoshop 8.0 as these are Christmas gifts.  Resolution is so bad I would be embarrassed to give it.  Have called Adobe support and held for 20 minutes before giving up and sent an email to support a week and half ago and have not had a response.  Can anyone help?  Right now I'd just be happy to give the CD slide show in a decent resolution from elements.

    I can't help you with the premiere elements problems, but VCD is an innately horrible format. You should be able to burn a regular video dvd by outputting your PSE slideshow as a WMV file and sending it to PRE to do the dvd authoring, or by using whatever dvd writing software came with your burner.
    There is no such thing as a decent quality, reliably-playing VCD, unfortunately. They're always awful.
