Different VGA cable = different resolution?

So I ordered a new (cheap) VGA cable and after I hook it up my resolution dropped from 1680x1050 down to 1024x768. I wasn't using any xorg.conf.d settings before (but it looks like I may have to). If I load X with the old cable in place, everythings correctly auto-detected and switching in the new cable at that point gives me the proper resolution so it should be possible to use the new cable at the right resolution after I mess with xorg.conf.
Has anyone run into something like this before? I thought DDC and auto-detecting fixed this.

well, you need to read your edid and see if your cable is too cheap to actually transmit it without errors.
ive got this issue with my samsung 20" too. but i never replaced the cable. it actually stopped working, i forced it through a modeline and kept on with my life

When i connect my mac book pro to an external display using a VGA cable and adaptor, the external display splits into several different columns of the same screen overlapping one another. Does anybody have any ideas as to why this happens?

I have used different VGA to mini port adaptors, different VGA cables and connected them to different external monitors and prjectors but the same thing happens. I am starting to think there may be a problem with the macbook itself however, when i have used a HDMI lead and adaptor to external monitors the external display is fine.

Hello-
I am trying to project a film from an ipad mini with a vga cable to a projector. When tested, the film played, but the ipad did not mirror what was being projected, it was a black screen. I am trying to be able to mirror the devices AND figure out how isolate the window so I can use different menus with the film still playing.
Any one know an app or softward that i can use?
Thank you!

To move an iPhoto Library to a new machine:
Link the two Macs together: there are several ways to do this: Wireless Network,Firewire Target Disk Mode, Ethernet, or even just copy the Library to an external HD and then on to the new machine...
But however you do choose to link the two machines...
Simply copy the iPhoto Library from the Pictures Folder on the old Machine to the Pictures Folder on the new Machine.
Then hold down the option (or alt) key key and launch iPhoto. From the resulting menu select 'Choose Library'
and select the Library that you moved. That's it.
This moves photos, events, albums, books, keywords, slideshows and everything else.
Your first option didn't work because you imported one Library to another. Every version and thumbnail is imported like a distinct photo, you lose all your Albums, Keywords etc., the link between Original and Previews is destroyed, the non-destructive editing feature is ruined and so on. In summary: it's mess.
Your second option didn't work because you simply referenced her library on the old machine.

[SOLVED] Configure dual head with different resolutions xf86-video-ati

I have 1680x1050 and 1280x1024 monitors which I would like to setup so that I have two displays (:0.0 and :0.1), i.e. can't drag a window to the other display, but can move the mouse from one screen to the next. The graphics card is Radeon HD 4850.
At the moment I have one screen only, so I can't move the mouse from the first to the second screen, it is captive in the first screen.

It doesn't look as if xrandr can help as it reports a maximum virtual desktop of 1680x1680.
Because the two monitors are different resolutions I don't know if a single screen is the answer.
I used to have two displays/screens configured to two different resolutions matching the monitors using the catalyst driver but can't get it working using the xf86-video-ati driver.
Any help would be appreciated.
Thanks

Cine 30" raedon x800xt and an addidtional (different resolution) monitor

I have a G5 with a 30 inch cine display and a radeon x800xt video card. I would like to get an additional 19 inch monitor to use as a tool pallate. I am not schooled on video cards, but can I add a second monitor of a lower resolution.....(again i am only using to park tool pallates)....and have the video card recognize two different resolution settings.

The X800 can handle two monitors, with independent settings for resolution. The DVI port can handle a display up to 30" (2560 x 1600). The other port (ADC) can handle up to 23" (1920 x 1200).
If the second display is not ADC, you will need an adapter, either ADC to DVI, or ADC to VGA. (ADC to DVI, followed by DVI to VGA, won't work, because most ADC to DVI adapters don't pass the analog video signals needed for VGA.)

Mirroring Desktop at Different Resolutions

Hello,
Does anyone know if it is possible to mirror the desktop at different resolutions without my cinema display shrinking down the viewable area? I have a seperate 27" hdtv in my living room hooked up and I want to be able to use both displays on the desktop. When I choose to mirror, then change the resolution on my cinema display, it makes the actual viewing area the same resolution (in size) the same as the hdtv, and leaves a lot of blox surrounding the viewable area, but the tv looks great. Is there any way I can run the cinema display in full screen used at native resoluting while using lets say the hdtv at 800x600 both mirrored?
I am going to try and switch the ports on the back of my macpro and see if that makes a difference, any suggestions would be awesome!
Thanks,
Tim

Thank you for the reply, unfortunetly I know what your saying, I do know the difference between screen spanning and mirroring. I have a specific need where I want to mirror my desktop to two different screens at different resolutions. That is simply it. I have set up my hdtv in another room and cannot use the screen spanning since a) I cannot access the dock from my lcd, becuase my cinema display screen is in another room b) half the time I cannot even find the mouse. When I setup mirroring, and attempt to set the cinema display to bative 1600x1050 resolution, it puts the screen in a type of compressed viewable, where the actual dimensions are 800x600, which is what my hdtv is running at (I have to run it at 800x600 because I am using a homemade vga over cat5e converter and the hdtv looks and runs bests (without ghosting) at this resolution).
So the main question is, is it possible to diplsay the same desktop onto two different monitors at different resolutions with distortion of either dispkay?
If you would like a photo of what is happeneing on my cinema display, just let me know, it is hard to describe and I dont blame the doubtness of this thread.
Thank you for helping out!

HP 6730b can I swap screens with different resolutions?

Hi,
Is it possible to swap screens with different resolutions on a HP 6730b?
Mine is 1680x1050 pixels and I want to find a 1280x800 screen to replace it.
(letters are far too small for an old fart like me. ;-)
The resolution list does support 1280x800 but it looks like viewing the screen through dirty glasses.
Just wondering if the interface is the same.
Cheers,
Bas

Usually people want to go in the other direction. Here is the Service Manual:
Manual link
The parts list shows a panel that is SXGA+ (1400 x 1050) and a WXGA (1280 x 768 or 800) panel.
There are multiple motherboards, but the only difference appaears to be whether there is a slot for a cellular card or not. In other words if you install the WXGA panel the motherboard should work with it and you will get 1280 x 800 resolution looking good. Laptop displays and other digital panels only work at their maximum aka native resolution and you get that muddy look if you try to run them at a lower res. You want to buy the whole panel with the cable designed for the WXGA....sometimes the cables will not work with a different resolution screen. Post back if you need further help finding a screen. You may find it cheaper and easier to sell or trade your laptop for one with the lower resolution screen.

Can I print photos at different resolutions in one PS5 file?

I am printing photos on fabric. I'd like compare one printed at 300dpi and the same photo at 150 dpi. I was going to set them side by side on a piece of fabric and realized I had to specify the resolution of the file I'm placing them in. Can I have two files at different resolution in one file? If the new file is of 300dpi resolution how does this affect the image at 150dpi? Thanks!
Mary

Hello again,
thanks so much for helping a newbie sort things out. I'm still confused. I know that a higher resolution like 300dpi, has more dots per inch and has the potential to give me more detail in print than a lower dpi.
If I crop a raw file as an 18" square- I will make it either 150 or 300 dpi. I'm trying to place two images ( the same images) side by side in a photoshop file to compare the results when they print- (I'm printing with an online vendor). Can I do that? that is, place a 150 dpi image next to a 300 dpi image in one PS file, identified ast 300dpi ? What are the print results? Will both images look the same, or will the 150 dpi be converted to 300 and I won't see any difference anyway?
Or, do I need to set up two separate files-one at 150 and one at 300, and print them separately, to compare them?
Can you help me understand this? Thanks!

Multiple displays with different resolutions

The system is setup with two non-mirrored displays with the following resolutions: A) 1024x768 and B) 1280x1024 arranged as BA with A the menu'd display using an ATI 9000 Pro for Mac. During startup, approximately once inch worth of the menu's right items momentarily appear on the right side of display B 768 pixels down from the top. This problem only occurs in this BA configuration of differing resolutions and is independent of graphics cards (substituted the 9000 Pro with a mirror only AGP Navidia card and a mirror only PCI ATI Rage card combination which gave the same result). This problem first appeared using MacOS 10.3 which displayed several inches of menu instead of only an inch under MacOS 10.4. Anyone else seen this problem?
Dual 800 MHz QuickSilver Mac OS X (10.4.4)

Over the weekend, I explained this problem to one of the Apple Geniuses at an Apple store and then was able to duplicate the issue using a lap top and attached monitor in the store (not the same resolutions as my system; but, screens of similarly different resolutions). I raise this issue again because, as of late, additional things have been happening and I wonder if these are related to the core issue of an expanded desktop with two different screen resolutions. All of the widgets on the larger resolution screen desktop are drawing in the menu located in the smaller resolution screen when hitting the "i" to gain access to its control panel; however, not effecting the menu at all when moved to the smaller resolution screen. The other has to do with screen savers periodically blanking both monitors (as though the graphics card went to sleep) or having both monitors lose syncing (first occurrence today) where a cold start is required to bring the monitors on line again (I am going to have to figure out a way to test if the system is actually sleeping or the monitors have only gone blank before cold starting the system).

Why are my HD videos all importing with different resolutions?

Hi, I tried looking through like 10 pages of discussions on here and didn't see anybody else having this problem.
I have a Canon Vixia HF200, I keep the settings on MXP (highest quality 1920 x 1080). Every time I log and transfer my videos they import at different resolutions (everything from the same day will be the same), some of them come in as 1440 x 1080, 720 x 480, etc, when they should all be 1920 x 1080.
So, since some of them ended up being a completely different aspect ratio, I went into Motion>Distort and changed them all to 1920 x 1080, and I thought it was fine, but now I'm noticing that some of the videos look really out of focus (it seems like they get more out of focus every time I open it), so I'm thinking I probably shouldn't have stretched them....
I checked the original videos in the browser and they all say 1920 x 1080 now, when I watch them in the viewer, they actually look like good HD videos, but in the canvas they're out of focus...
I'm also working with multiple sequences, and when I copy videos from one sequence to another, it changes the resolution/aspect ratio/scale again, and becomes more blurry when I try to fix it.
So basically, I have a huge mess. I'm working on editing a documentary that I'm making and now most of the video looks bad and I'm not sure how to change it back. I even tried starting a new project and importing the original videos, but they don't seem to have the original quality.
Anybody know how I can either fix this or somehow replace the clips in the sequence with the originals in the browser to at least get some quality back?
Also, a lot of the time when I render, I come back to the computer and it says something like "Error: Illegal (something) render failed" and completely loses the rendering that it spent a long time doing.
I appreciate any help.
Lisa

Hi Lisa,
Your 1920x1080 clips most likely import at their normal frame size, and then you placed them in the wrong sequence. Make sure your +File > Easy Setup+ is set to *Apple Intermediate Codec 1920x1080i60* before you create a new sequence.

I see the same photos with different resolutions in my iPhoto library

I am trying to organize my photos in the iPhoto library by deleting those are stored twice or more. However in many doubles I found out that some of them exist in my library in different resolutions. My photos are imported either from my camera, or from my iphone, or from my iPad or from the shared photo streams which include photos imported from various apple devices.
What I see for example is some photos taken from an iPhone exist in both 2048x1536 and in 3264x2448 resolution and some others in 1224x1632 and in 1536x2048 (I guess these 2 resolytions are for the vertically taken thotos while the other 2 for orizontical). For iPad photos I see 2056x1536 and 2592x1936 for the same photos. All doubles have different names (eg. IMG_007 and IMG_1056 for the same photo). Furthermore some doubles include info about the camera (eg. iPad back camer 4.28mm f/2.4) and some others don´t (only info about the device eg. iPad).
Why is this mess happening in my library? Apparently I want to keep in my library the photos only in the maximum available resolution for better quality.
In relation to that I have the following questions:
1. When a photo or a video is shared in a photo stream, is its resolution decreased to a lower one?
2. Is there any way to see what the resolution is of the original photo stored in the iPhone or iPad, so that I can compare with the the same ones I have on my computer´s iPhoto library?
3. Is there any way to see the resolution and other info for the Photos in a shared Photo stream which are not yet imported localy on my computer?
Thanks in advance.

Happy New Year to all!
I made a test and I confirm what I was suspected at first place.
I uploaded a photo taken from my iPhone to the shared photo stream. Then I imported this photo from the photo stream to my iPhoto library on my Mac. The resolution in which this photo is stored locally is 2048x1536 and its size 961 KB.
Then I sent the same photo from my iPhone via e-mail. I opened the email on my computer and downloaded the photo. Then I imported it to my Mac´s iPhoto library. I checked the info out and the resolution is now 3264x2448 and size 2.2 MB.
Therefore the quality and resolution of the photos that are uploaded to the icloud photo stream is NOT the same as the original one.
I don´t know whether there is somewhre an option to change that, but this is what happens to me right now.

Different resolutions in proyector/iMac, same content?

Hi guys,
Is it possible to have different resolutions in a proyector and your iMac but to show all your work in both displays at the same time?
I want to show how to use a software in the proyector using the highest resolution in my iMac, which is different to the one of the proyector. I can't do it without using the mirror display option, which makes that I have the same resolution of the proyector in my iMac Screen, which supports a higher one. It only works for final powerpoint presentations (?).
Many thanks by the help!

instead of using the mirror option use the spanning option but in the displays preferance panel click a drag the dock and the menu bar from the "iMac" display to the "other" display this would make your primary screen the projector.
hope this solves your problem as i don't think there is any other solution

VGA cable extension causing resolution problems

Pavilion 6507c with HP 2010i monitor, Windows 7 64-bit. I am trying to separate the CPU and monitor by a few feet more than the original 6' VGA cable allows. Have tried an extension plus original, and also a single longer cable. With anything but the short original cable, the computer no longer recognizes the monitor - it shows it as Generic non-PnP, and will not allow 1600:900, so the picture is stretched. Re-installed 2010i drivers - still comes up generic.
Is there any way to extend the monitor distance without sacrificing proper resolution?
This question was solved.
View Solution.

I wouldn't be too concerned about receiving a no signal message when shutting the PC down. With a longer cable, the signal may degrade sooner causing the no signal message to appear during the shutdown process.
Displays work by the monitor sending the EDID information to the PC and this is part of how the PC identifies what resolutions are available to this monitor. The original cable is allowing this information to be sent from the monitor back to the PC. The PC then retains this information which is what allows it to work with the longer cable after swapping out the 6' VGA cable for a longer or extended one. Once the system is shutdown, the EDID information is lost. This is why it doesn't work once the system is shutdown and started with an extended or long cable.
You did mention an important difference between the cables: the lack of a ferrite core. This Wikipedia entry discusses ferrite beads (aka: ferrite core) and what use they have. Essentially, it reduces the level of interference which could cause the EDID information to be lost before reaching the PC. This is more noticeable when using a long cable, so this could be due to the lack of the ferrite core. However, the adapter listed in my previous post should rectify the resolution issue (though, it would still be listed as a generic PnP monitor).
I would weigh the cost of a cable with the ferrite core against the cost of getting an EDID emulator and select the cheaper option. I know an EDID emulator will rectify this issue, but I cannot say that getting a cable with the ferrite core will correct this issue with 100% certainty. I do know not having a ferrite core can cause signal quality issues. If you can still exchange the cables, then that may be the cheaper option.
Let me know what happens.

Is it possible to publish a project with a different resolution than the native project resolution?

I think I know what the answer is going to be here, but I'm going to ask anyway. The background here is that I've made a few demo videos for new products and features my company is working on. I'm using CP4 for this. Our marketing department wants to take AVIs of my demos and insert them into their Powerpoint demonstrations. However, the native resolution of our demos doesn't make for a graceful import into Powerpoint. Thus, I've been directed to provide smaller res AVI files.
Thus, I am wondering if you can publish a project at a different resolution than the one in which it was recorded. My initial poking around seems to indicate that the answer is "no," and if this is truly the case, I will be rumbling over to the "Suggest a Feature" forum soon. There does seem to be a kind-of-workaround in that you can change the resolution of the project before publishing it, but this is something that cannot be undone, meaning that in order to do this, I will have to save new, smaller versions of all my projects. This is a bit ungainly.
So, if anyone knows a good trick here, I would love to hear it!

Unfortunately, I don't know what you mean when you say "manual panning." And I'm really not sure what you mean when you say the fields are not fully visible in the original image; they are completely visible. Here's a close-up from the original slide:
As you can see, the fields are completely visible.
Also, the slide is not entirely static. For the slide I chose as an example, the Password is filled in before the mouse moves. This typing may be part of what is getting Captivate confused; note this sequence from the resized version of the project:
Slide 35:
The login window first appears. Everything is normal. During this slide, the mouse moves and clicks inside the User ID field, leading to...
Slide 36:
At this point, things begin to go awry. The user name is entered, and the cursor moves to the Password field.
Slide 37:
Whoops! As soon as we click Login, everything goes back to normal.
Slide 38:
I will try a few of the suggestions you offered, and will report back with the results.
