Mini & Samsung 215tw - help me with SwitchResX? I have a 90% solution

I hope I'm not off creating a new question topic for this. If it needs to be moved, by all means do so.
I got the Samsung 215tw today for my mini g4 1.42 and, of course, ran into a few problems. I also found 90% of the solutions using stock values in SwitchResX that were recommended for another similarly spec'ed monitor of a different brand. I'm hoping that someone with working knowledge of SwitchResX might be able to fine tune the custom values to make a 100% solution. I'll detail the problems/solution below:
I initially just plugged the monitor in using the dvi connection, without turning off the computer. The screen worked instantly with a perfect image - no "digital noise lines" as I've seen it described.
I did have problems though:
1. When I restarted the computer, the monitor would stay blank, going into power saver mode. I could bring it back by turning off the monitor (with the toggle switch), putting my mini to sleep (i have the power button set to sleep it, not turn it off), then turning the monitor back on and waking up the computer. Not an elegant solution, but it made it functional again to further play with the settings.
2. When I tried to use any of the mac screen savers, i would get a moment of "noise" on the screen and it would go blank. Again, i'd have to turn off, sleep, turn on, and wake using the same half-way solution.
3. When I tried to rotate the monitor and change the os settings to 90-degree rotation, it would work for a second, get that noise, and then go blank. Once again, that four step turn off/on/etc would bring it back.
So I tried using the SwitchResX solution posted here (now an archived thread):
http://discussions.apple.com/message.jspa?messageID=1707980
I don't really know what I'm doing with the various numbers, so I essentially just copied the values Tom Fussy gave to Alehning. Once I did that, I had near perfect operation.
When I boot the computer, I don't see the apple logo and the progress circle, but once the desktop is ready the monitor works fine. The screensavers work perfectly. The rotate works almost perfectly - the only flaw is the motion when dragging windows etc is kinda choppy.
I'm hoping that further play with the values will fix the choppiness after rotating and maybe even the display of the boot screens.
Here is the exported DDC file from SwitchResX before i made any changes:

Hi Plan,
A couple of things:
1). Have you tried downloading the source for the demo to see if there's anything in there being done differently?
2). To file a bug report, you go to My Oracle Support (MOS) and open a service request. If you don't have a support contract with Oracle, there's no "official" way to do it I'm afraid.
Best,
John

    hi i need help with my ipod nano i want to transfer my music from the ipod to the itunes so that i can be able to transfer the music to my ipad can you help me with that ?

    You cannot use iTunes to transfer song files from iPod to computer, except for songs purchased from the iTunes Store.  However, there are third-party methods and utilities that can transfer from iPod to computer.  If you do an Internet search on something like"iPod transfer," you should get some links.  (The CNET article seems to be popular.)
    Once the song files are on your computer's drive, you can add them to your iTunes library, and then sync your iPad.

  • Any Mini DisplayPort to HDMI adapter with audio for macbook pro mid 2009

    connecting MacBook Pro (15-inch, Mid 2009) to Hisense TV with audio?!?!!?
    hello everyone.
    if anyone is familar with successfully getting the older macbook pros that dont support audio out to stream and preform digital audio on a TV or has any helpful information that will get me familiar with trying to successfully stream audio and visual. and can PLEASE HELP ME in any way to understand what they know and teach me how to solve my problem id really appreciate it.
    i want to connect my MacBook Pro (15-inch, Mid 2009) to my Hisense LED LCD TV, ModelNumber:40H3E  and getting digital audio sound from my TV as well as video, but have no clue on how or where to even start to successfully pairing the two and getting sound.
    I own a MacBook Pro (15-inch, Mid 2009) this MacBook model doesnt support an HDMI port. My MacBooks model has the Mini Displayport which supports video out but does not support audio out. Can someone help me by telling me exactly which Mini DisplayPort to HDMI adapter with audio will support my model MacBook Pro (15-inch, Mid 2009) and exactly what HDMI wire do i need to buy that will successfully preform digital audio and sadisfying quality visual through TV?
    i have NO expierence with the proccess have NO knowledge about any of this or these Mini DisplayPort to HDMI adapters with audio. i have no idea what kind of adapter and HDMI cord to buy that will give me sound from my tv for my type of macbook. '
    im not familar AT ALL with any of this so i hope me giving you my MacBook Pros make and model and my TV's model number will be enough information for someone to help me.
    just please give me anything you can on this topic
    thank you so much,

    With a 2009 MacBook Pro, you need to use two connections to your TV: one for video and another one for audio.  The miniDisplayPort on the 2009 models does not support audio, so you need a separate audio cable:
    miniDisplayPort adapter for video - I use the Apple miniDisplayport-DVI adapter + a DVI-HDMI cable like this one
    audio cable for audio - use a 3.5mm male stereo-to-2xRCA male cable like this one
    Connect the miniDisplayport adapter + DVI/HDMI cable to your MacBook Pro's miniDisplayPort output and the HDMI input on your TV
    Connect the audio cable to your MacBook Pro's audio out and your TV's audio in
    The only potential gotcha is if your Hisense TV requires audio via the HDMI cable when you use an HDMI cable.  The H3e user manual is unclear about this.

  • Help needed with IMG SRC

    Can anyone please help me with this: I have created my own website on IWeb and now I want to use some of my banners on other websites. Problem is: there is something wrong when I fill in the img src code. The banner does not appear, only a question mark. I do not know the answer to that: am I using the wrong URL code or is it something else? I have placed my banners in the public folder, but that makes no difference. Thank you in advance for your help.

    Welcome to the discussions. Assuming your image is in the top level of your iDisk's Public folder, the HTML should look similar to this:
    <IMG SRC="http://idisk.me.com/membername-Public/Image.jpg"/>
    ...If the above doesn't help, post back here with the HTML you're using. You can convert it to character entities for display in this forum via _this site_.

    You really need a newer Mac Mini with a true HDMI output, because that Mac Mini's DVI output does not support Audio.
    You might try a 3.5mm to RCA adapter
    from the Mac Mini's headphone jack to the TV's audio input,
    but that would require being able to select the Audio input in the TVs menu while using it's HDMI input.
    Optionally you could also use an external 2.1 Speaker System or patch the audio from the Mac Mini to your home stereo system to enhance that older Mac Mini's audio.

  • I have connected my new Macbook Air to my existing Samsung large external monitor with a VGA adaptor but I can't get the full mac desktop to display. No icons but then websites are coming up. Help!

    I have connected my new Macbook Air to my existing Samsung large external monitor with a VGA adaptor but I can't get the full mac desktop to display. No icons but then websites are coming up. Help!  Further info:  I am a complete newbie to Mac.  Had three macs prior to 2000 then four PCs.  Just come back and struggling a bit with the unfamiliarity. On my old PC laptop I could simply switch from the laptop screen to the large external monitor (and back)  with the F4 function key.  While I can get the background image from my MBA to display, that's it.  Until I noticed on the far left of the external monitor, the very edge of one of the web pages I was on.  So Idragged it over to display in the centre.  But that's all that's there.  And now I have gone out of those web pages but they are still displaying on the monitor.  There is some wierd disconnect.  I'm sure it is just a setting thing.  Will keep searching for answer but any advice welcome!

    Your dsplay is getting extended onto the external monitor. Chcnage the setting to duplicate it or only display on the external monitor and you should be fine,
    Let me know if this worked for you.
