TV-out (Mini-VGA to S-Video) Horizontal Lines problem

Imac Intel Core Duo running 10.5.8 2ghz
i want to watch movie files on my tv. i bought a mini vga-to-video adapter from Apple. However, whenever i hook it up to my Tv, i get these rolling horizontal lines on the TV screen. i have tried every resolution combination, unplugged all extraneous plugs from both the Tv and computer. All to no avail.
this *****- i used to watch movies just fine on my eMac. ..if anyone has any ideas on why i get these ghost lines they will be much appreciated. thanks!

The manual doesn't state that this will work. I recommend you contact MSI and ask. >>How to contact MSI.<<

I need to connect I-Mac G5 to HDMI TV, I think I need this: Video Out: mini-VGA (mirror only) to HDMI, where can I buy? Apple Bluewater no help.

VGA is an analog signal HDMI is digital. A simple cable would not work you would need something that converts the analog signal to digital.
A search of VGA to HDMI turned up a few possibilities but nothing specific. In any case the picture on the TV will not be very good given the source.
You should check to see if the TV has a VGA input. Some TV's have a computer connection port and this is usually VGA.

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.

Mini-VGA to S-video Adapter / Getting Original Display Setting Back

I purchased the Mini VGA to S-Video Adapter. Works good with my HD Television. But no I cant get my original Display settings back. I dont know exactly what the setting was but it had more screen space. Please Help, Ryan

So you have a good picture on your TV but not your mac?
Open the display pane of system preferences, leave the settings that come up under VGA Adapter (or whatever it calls itself) But for the iMac settings, colour should be millions, and then just go through the different resolutions until you find one that you like.
Let us know how you get on.

Mini-VGA to S-video resolution problems.

I have recently hooked up a Apple Video Adapter that connects from my 17" iMac 1.8 GHz G5 Mini-VGA port to the S-video port on my RCA TV. My problem is that while it is plugged in I cannot put my iMac resolution at the proper 1440 x 900 because the option is not there. In order to get the 1440 x 900 option back, I have to unplug the adapter. How can I fix this so I don't have to unplug the adapter?

Had the same problem here (drove me crazy) Search for ScreenSpanningDoctor. It will easily solve your problem.

Mini-VGA to S-video only gives a black&white tv-screen.

When I connect my emac G4 with a video adapter (through mini-VGA) to the S-video port of my tv it doesn't have any colour. How can I change this? The image is perfect but its just black and white.

thanks for the help guys, i solved it by using a standard (we dutch people call it a tulip) cable instead of a S-video cable. Still don't know what the problem really was with that..

Mini-VGA to S-video

I have the mini-VGA adapter to connect my iBook to my S-video input on my T.V. Can I use this to view movies in my iTunes library on my T.V? Can I expect decent picture quality? Is it possible to stream the audio content through my airport express to my home theater audio? Suggestions and tips appreciated.
Thanks in advance,
Paul
P.S. Hope this is the correct forum for this post.

yes, you can use the s-video connection to view video. the video would probably be fine, but with the computer having a superior image. i think most people would want that set up just for the larger resolution. if you had a dvi or hdmi connection it would be better. as far as the audio goes, sure you can use your speakers. the thing is though, is that they have to be hooked directly to the airport express. there is no way around that. and then you go to your itunes preferences and make sure that itunes has searching for remote speakers enabled.

How can I connect an ADC to an iMac G4 with mini-VGA port?

I have an Apple Studio Display monitor that I want to connect to my iMac G4 that has a mini-VGA port. I have the ADC to DVI adapter, but cannot find any adapters that go from DVI to mini-VGA. Please help!
I "inherited" these devices for work from a different university. They originally used the extra monitor with a PowerBook G4 that has a DVI port. But I would rather use it with the iMac - is it at all possible???
Thanks!
iMac PowerPC G4 Mac OS X (10.4.5) 1.0 GHz 768MB DDR SDRAM

Hi,Welcome to Apple Discussions.
Depending on the age of the iMac G4 depends on what outputs are possible:
700/800MHz - Mini VGA port to VGA port
1.0/1.25GHz - Mini VGA port to VGA port or Mini VGA to S-Video/Composite.
I'm not sure if the first revision of 1.0GHz iMac (Early 2003) fell in to the first category or the latter one.
regardless... these adpators are available at theApple Store online for $19/£15. From there you'd need to find a VGA - DVI convertor and then the DVI to ADC convertor. Googling for such adaptors brings up several results.

Mini display to s-video possible?

Hey everyone.
I have an aluminum mac book, which has the mini display port on it. I saw in a store there is a mini-vga to s-video...but what about mini-display? Basically I want to be able to hook up an s-video to my computer so I can watch movies on my tv. Are there any other options I'm unaware of?
Thanks,
-Neil

There is NO way to directly connect to a standard-definition TV through a Mini DisplayPort (i.e. no simple cable adapter).
However, you can connect using a setup similar to what is discussed in the following post:
http://discussions.apple.com/message.jspa?messageID=8361557#8361557
If you want to connect to an HDTV (DVI or HDMI) see this post:

Black screen on startup; horizontal lines on screen precede crash

A few days ago my Mac Book Pro screen freaked out. Specifically, it had multicolored horizontal lines all over, but underneath I could see a dark grey dialogue box telling my to restart the computer.
Now, about two thirds of the time, when I try to start up the screen stays black and it does not make any startup noises but the power light comes on steady. One time this was accompanied by a beeping tone that beeped in sets of three. The other one third of the time it starts up fine.
Once it shut itself down after the horizontal lines appeared again.
Once it has frozen while on the screensaver and I had to manually shut it down.
Any idea what might be causing this? My computer is still under warrantee but I live over an hour and a half from the nearest apple store.

Welcome to Apple Discussions!
If you have the NVIDIA GeForce 8600M GT video chip, you might be developing this problem:
http://support.apple.com/kb/TS2377
The beeps and kernel panic do seem to point to a RAM problem. If you replaced the original Apple RAM with 3rd party RAM, try the Apple RAM if you still have it and see if this cures the problem. Otherwise, try reseating it as described earlier.
Here is an article that may be of help:
http://www.thexlab.com/faqs/kernelpanics.html
Finally, since you are so far from an Apple Store, call Apple on the phone and explain your problems. It's possible that they could refer you to an AASP in your area that could evaluate your machine and save you a trip. It's also possible they could determine that you have some sort of hardware problem and could send you a box to ship your Mac to the Repair Depot. In any event, be sure to contact Apple while your warranty is in effect and get a case number, especially if you are getting close to the end of your Applecare.
Good luck!

Macbook Air early 2014 - Horizontal lines in screen

Hi to all,
I would like to add my problem to the community. I bought this September a Macbook Air (i7,8GB RAM, 256GB, Samsung Display LSN133BT01A02) and I had the horizontal lines problem. As you understand the problem is not great and it does not affect the performance of my Mac but since I bought it I want everything to be perfect (it is not a cheap machine). So, I contacted Apple and they suggested me to go to an Apple Service Centre. The "geniuses" changed the Logic board and they have done a mistake in its order, so I had it back with an i5 processor. "Fortunately", even with the downgraded machine I had the same problem. So, I recontacted Apple and I had a replacement of my machine. Now, I have one new machine (i7,8GB RAM, 256GB, Samsung Display LSN133BT01A02) and again the same problem. Guys this situation drives me crazy and completely disappointed with my Air (ok, I know that I may overreact), but my main issue is to find out if this is a software or hardware issue. In both cases (old and new machine), the lines were appearing after many hours of usage, they had a length varying from few inches to the whole screen and their number were mainly one (one pixel thickness). An other interesting point (that makes me believe in the software issue) is that the colour of this line was the one of the previous window that I open. As a result, having many windows open, the colour of the line is the "damaged" colour of the previous window that I minimise.
To troubleshoot the problem I have done a complete format of my Mac, SMC reset, PRAM reset but still the issue is there. When the line is there I move the screen and nothing happens & in the screenshot the lines are not present.
Now, I want to discuss about the possibility to be a universal problem with Airs (and especially with the ones that have Samsung Display). I am wondering about the possibility of being so unlucky since also other guys had the same issue after even 3 replacements. I really opened this thread so as to hear your opinion and if somebody troubleshooted the problem it could be extremely interesting. I would like also to add that also in Yosemite the problem is still there.
Thank you all!

Just to add also a more technical view point: I said that I have this problem after many hours of usage. So I guess that a garbage collector (software base) of the Mac does not work so properly and consequently it leaves garbage to the memory. This may lead some timers (internal clocks) to sub-function and as a result the rendering of the graphics to be damaged in some points.
I am not an expert but I try to guess what is happening.
Thanks for any contribution.

EMac mini VGA video out

Hi guys I just got the apple mini vga video out adapter this morning. What Im trying to do is record what is on my screen to mt sony pd150 camera. I do not have a s compsite lead as yet so im using the standard video audio adio lead.

Options for VGA to S video/ composite video over Mini displayport

I have a mid 2009 13" macbook pro that i want to connect to a standard def tv with s video and composite inputs. I already own the mini displaport to VGA adapter. I have found two adapters on amazon that convert VGA to s/composite video. one is $4 and is just a cable. The other is a $40 box with vga input and video output. my question is, do i need to shell out for the expensive one or will the cheap cable do just fine? i have heard NTSC out a lot while poking around. does my computer have that?
Adapter #1 (cheap one) http://tinyurl.com/yc6topv
Adapter #2 (expensive one) http://tinyurl.com/yd6qnvs
Any help would be greatly appreciated.
Thanks!

Hello, I am first time forums user and a new mac owner.
What I am having trouble with is a very similar thing but I have a brand new macbook pro 17 so I am pretty sure my connector is slightly different. I found this...
http://store.apple.com/us/product/M9319G/A
This seems to be a connector which comes out of the mini-dvi port and has a connector for rca/svideo. I have a mini-dvi to vga that I bought with the mac and then I have an old vga to rca/s-video connector cable like the cheap option the original poster gave.
My mac responds as it should but the tv signal is totally screwed up. I also tried hooking it to a projector using rca and that said no signal. The mini-dvi port to vga works but I am not 100% on the vgs to rca connector I haven't used it in so long. It is going to be a pain for me to test it though.
Should this work? DO I need to mess around with refresh rates?
Thanks

Mini VGA to Video Adapter ???????

hi - the screen on my old emac is gone (just a vertical line in the center of the screen). i got a new emac (used). i want to transfer the files from the old one to the new one. i need to hook it up to another monitor in order to navigate the system to allow for file sharing. i want to use the "Mini VGA to Video Adapter" and use the composite video connection to hook up to a television set as this seems the cheapest and easiest route on this but many of the listings on the net say that an emac with airport extreme is required. i don't know if my old emac has airport extreme installed. i don't understand why i would need airport extreme if i only need the rca jack connection. does anybody know if this will work without airport extreme ? the old emac is a 700mhz / g4 / 40g / 1g ram - thanks, beaner

seems that i have found the answer to this myself. finally found the actual apple page for this (see link at end of message) and 2 of the reviews for the part say that this adapter will not work on my circa 2002 700mhz emac but works on later ones.

Mini-DV to S-video out resolutions

I read a number of posts here about monitor/TV screen resolution conflicts, but I want to make sure I have this straight...
When I connect my 24" iMac to a standard 4:3 TV with Apple's mini-DV to S-video adapter, the monitor resolution reduces from 1920x1200 to match the TV screen's lower res, with a large black border covering much of the monitor.
This is OK if I'm just showing a QT movie, but I want to see After Effects footage on the TV as I work on it. And I need to work on the footage full-screen on the iMac.
Any way around this problem using the $20 adapter? If not, is there a 3rd-party solultion?
Thanks,
Andy

Thanks namke, had no idea that rectangular pixels were employed to achieve widescreen on a TV - you learn something new everyday!
I wondered what other MacBook users get when they plug in the mini dvi to s-video adpater because 16:9 resolution is an option when a DVI adapter is plugged into my Mac mini (e.g. 1024 x 576), but not my MacBook.
