S Video a or DVI/VGA out

I'm connecting to a projector for Keynote presentations and have both an S -Video and a VGA input on the projector. Which input will provide me with the best resolution?

No video with mini dvi - vga adapter (2007 Macbook)

Connecting an external TFT display (Nokia 500 Xa) to my MacBook's mini dvi port with a mini dvi to vga adapter, there's no video.
Any ideas about what might cause this? the monitor is a bit old, but VGA should still be the same, eh?
I thought maybe it's the adapter's pin configuration... What exactly does the adapter let through?
Grateful for any ideas.

Apple DVI to VGA out adaptor

Hi All,
I got an Apple DVI to VGA out adaptor and I have a Radeon 9000 video card with ADC and DVI output, the thing is that when I plug that in, it sees it as a VGA output, but when I connected the other end to an input on my tv, it displays nothing and when I click DETECT DISPLAY, it closes the tv connection and I am back to one display..
Now I also have a Radeoan 7000 PCI card with VGA, DVI and S-Video out and when I connect that same adaptor, it now says Televison and works as it should... Now my question is the DVI output is different on each card or is it PCI and AGP slot acts differently or do I just have a bad DVI output???
thanks and I aplologize if this is NOT the forum for this question...

The DVI connection should work, but some displays with multiple input have trouble after the display or computer sleep. I think the display sees no signal on the computer port so goes to checks the other port. When the computer wakes, the display may be switched to the wrong port. The computer, may, then, think there is nothing connected, and turn off the video. The display comes back to the correct port, but sees no signal, and switches ports before the computer has a chance to start the video. A properly designed display would send connected signals on the DVI port while it's looking at the VGA port, but some models never recover properly from sleep with certain computers.

Macbook 2,1 dvi-vga video adapter, which one will work?

Hi all,
I just purchased a mini dvi-vga video adapter (M9320GA) for my macbook 2,1 and it didn't fit. So this time I want to make sure I get the right one so I can hook up my external monitor to my laptop. Would you be kind enough to point me in the right direction?
TIA, Tross

Thank you for the welcome Doug!
Well if it should fit all macbooks my Macbook is either a mutant or the adapter is, as it is the laptop-adapter connection, that is the problem. I intend to plug it into a DVI monitor and that end fits fine.
To be more specific the avi connection when compared to the port it plugs into, is too narrow. That is, the sides are the right width but the adapter connector isn't tall enough to fit. Perhaps it would help you understand what I'm saying better if you saw it, so I'll include a link to the ebay page I'm reselling it on:

Screen says "use tv as display" have vga out and tv has rca or s-video in can I?

I have old ze4935wm laptop with XP
Quick button properties screen says "use tv as display"
It only has vga out and tv only has rca or s-video in.
How can I do this?

I solved that problem.
If your tv also has component imputs- the red/ble/green cables that look like ordinary rca cables-
as a matter of fact you can use the regular rca audio/video cables, I do.
Tiger direct has an item called.PC2Tv.
It has a box- (size of a deck of cards) connect the vga wire from the box to your computer,
connect the usb wire from the box to your computer.
Then run the rca cables from the box to your tv.
It comes w/ a remote, you can adjust contrast, color, sharp & brightness, etc.
It's powered by your pc/laptop and cost about $20.
I use one on my patio where the rear projection tv has an hdmi input, but it doesn't work for computers-
the tv's manual says that the hdmi input is just for dvd players.
I also use one in my garage, where I have a crt tv.
Works perfect.

T500 VGA out to component video

Does anyone know if this adapter:
http://www.monoprice.com/products/product.asp?c_id=102&cp_id=10235&cs_id=1023503&p_id=2170&seq=1&for...
will allow me to connect the VGA out on my T500 to an older HDTV with component inputs?
Thanks in advance everyone!

That should be fine, I think. I'm running a 40" Toshiba 1080p LCD which I think looks awesome, but plasma TVs are a bit more expensive and you might not be able to get one with 1080p without a good chunk of change.
One thing to note: the cheap HDMI cables work just as well as the expensive ones. I spotted no difference whatsoever between a $15 cable from a local electronics store and one that I had been mistakenly talked into buying for over $100. Needless to say after running that test I returned that cable the next day.

T500 XP 32 - 2 external monitors - one in VGA-out & one in DisplayPort ? (1920x1080 & 1280x1024)

I searched and found some information... but the information wasn't specifically clear, so better to find out for sure, and help archive some clear information for the community...
I'm looking at attaching 2 external LCD monitors to my T500 (2082-3HU). OS is XP 32bit.
One will be a 19" 1280x1024,    and the other will be a 27" 1920x1080.
Plan is to connect 1 to the VGA-out and 1 to the DisplayPort.
First.. will this work?
Second.. which is better to attach to which port? (and why?
and
Third.. what are the maximum resolutions that the VGA and DIsplayport ports can provide?   Does it matter if it's VGA or DVI?
I was going to get a USB to video adapter for $50+, and then remembered the DisplayPort!    If it will work, it's a great way to save some money, get much better video res. and speed, and keep a USB port free.

Here are two posts I found ... (they appeared out of no-where)
you can connect two external WUXGA (1920x1200) monitors to the T500 using both the VGA and displayport connectors.   no other hardware is needed besides the display cables.

I connected 2 external monitors (1 thru Displayport , 1 thru VGA port ), and it works fine, its very easy to configure it using Lenovo Presentation utility.
But now I have the view only on those 2 external monitors (notebook display is off)
http://forums.lenovo.com/t5/T400-T500-and-newer-T-series/T500-with-2-more-displays-thru-Displayport-...
and for any more monitors, a USB-VGA, or USB-DVI adapter can be used... from lenovo, or EVGA or any other good type.
DisplayPort can support, at least, 2500x1600
http://forums.lenovo.com/t5/T400-T500-and-newer-T-series/Can-T410-w-built-in-Graphics-support-the-De...
use a Lenovo usb2dvi converter and the displayport to dvi converter.
This will allow you to use 2 external WUXGA monitor. If you need to support more WUXGA monitors, then you just need to get more Lenovo usb2dvi converter, up to a maximum of 6 (maybe slightly less i can't remember) using the integrated gpu.

[SOLVED] Thinkpad T61: No VGA out

Using KMS (kernel mode setting) ... no xorg.conf.
xrandr doesn't even see the VGA cable as plugged in.
I see notes on /proc/acpi/ibm/video on ThinkWiki ... mine looks like:
# cat /proc/acpi/ibm/video
status: supported
lcd: enabled
crt: disabled
dvi: disabled
auto: disabled
commands: lcd_enable, lcd_disable
commands: crt_enable, crt_disable
commands: dvi_enable, dvi_disable
commands: auto_enable, auto_disable
commands: video_switch, expand_toggle
However, lcd, crt, and dvi changes have *no effect* when echo'ed to the file as root, even with X not running. This despite the fact that it shows status supported, and auto toggles just fine.

No dice. Only related BIOS setting about that is boot display preference. I tried setting that to VGA+LCD ... didn't work. Too chicken to try just VGA, lest I be unable to see the BIOS again.

Sudden no DVI/VGA signal

Pavilion p6210y. Stock, nothing fancy.
Over a year ago my power supply exploded abut I replaced it with a Norwood Micro 350W I found in a free box. It worked just fine, we used the computer for about 6 months then set it aside because we got a laptop. The other week I started it again and it worked fine for about 30 minutes then the monitor shows me no DVI/VGA signal and go to sleep. The computer is still running. I let it rest for a day and then started it again and the same thing happened. Power supply? Motherboard?
Thanks!,

Hi Joe,
Your PC might be full of dust and then overheating.
Try this procedure:
Unplug the PC and open it up. Clean out all the dust. Carefully remove and replace all the cables going to the motherboard one at a time. Do the same for the memory dimms and the video and sound cards if you have any. You might want to buy a can of compressed air to blow the dust out of the CPU heat sink. Plug your PC back in and give it a go.

Anybody got the Vga out working in Bootcamp yet?

I would like to use my nice big 26" screen while in bootcamp. I know it hasn't worked with the vga out. Has anyone got a fix?
Also the tv takes multiple inputs, Dvi and S-video, so is there another way to get this to work?

No problems, although I can't see anything special that I'm doing that could help!
I've got my TFT monitor connected via it's VGA cable to the DVI/VGA adapter supplied with my MBPro.
I go into display properties, settings tab, and change the resolution for the main display to match that of the external display (1024x768 if it's a projector, 1280x1024 in the case of my monitor). I've not found a way of running the MBPro and the external display at different resolutions yet, but that's no big deal for me.
Now I click on the Advanced button and then click on the Displays tab with the ATI logo on it.
This brings up a dialogue with 4 displays on it. 2 Monitors in the top row, the MBPro's panel bottom left and something labeled FPD in the bottom right. Each of the displays has a power button. I need to turn on the monitor in the top right to output the display to the external monitor.
Hope this helps!

Mini dvi-vga problem - Need help

When I connect my mac mini to a 32 inch Samsung HDTV via a dvi-vga adapter, the source is not recognized. I jsut get a black screen. However, when I connect it to the HDMI port, it works great. But, I wantto use the HDMI port for the Television source, not the computer source.
Any ideas?
Thanks

Did you get the mini-DVI to VGA adapter from Apple? Are your other cables okay?
Perhaps a mini-DVI to video adapter would be a better choice for you.

Macbook mini-dvi -- VGA projector problems

Hi
At the school i teach at we have problems hooking up our new macbooks to one of our projectors. We use a mini-dvi --> VGA cable to hook up the projector. The mac recognises the projector and it gets listed under screens, the resolution also changes. But no picture is beeing projected by the projector.
If we use a mini-dvi --> s/video/rca cable it works fine, but the quality of the picture is too low. The projector works nicely with the older macs we have, wich use the mini-dv --> vga cable.
Any toughts on what may be the problem, or what we could try?

I am having the same problem. I have to do powerpoint presentations at college and it was so embarrassing to go up there and my macbook not sync up. It use to work. I even bought a new adapter. It did not fix the problem. All the windows laptops were able to sync up to the projector but mine did not. This one one of the main reasons I bought a macbook. I need to take my work to school and connect to projectors. I am using the mini-DVI to VGA adapter. There appears to be no physical damage. When I click detect displays nothing happens. Now I have to redo everything on windows. Please, I hope someone has a fix for this. I am using the following; 2 GHZ Intel Core 2 DUo, 1 GB RAM, Mac OS X 10.4.10

How can i use the DVI-VGA adaptor under this particular circumstance?????

I got a LCD only has DVI-I port, while as u guys has noticed, the MBP only got DVI-I too. So, my first thought is to get another DVI-VGA adaptor. What i'm doing is to hook up the VGA port then plug each DVI port to LCD and MBP. Well, the problem comes out that MBP was able to indentify the Monitor but no image apears on Monitor. How can i solve this problem? Or do i need to buy any other accessaries to configure my MBP in order to make it work with the **** Monitor!

Right. You don't need a DVI-to-VGA adapter to connect DVI-to-DVI, obviously. The included DVI-to-VGA adapter is not meant to connect to the external display/projector, but merely to give you the proper connection to connect the VGA cable of the display/projector. I give a lot of presentations, everywhere I go there is a long VGA cable (at the podium, conference table, etc.); the short adapter is nice because I'd rather not carry a long cable with me...

Dual Monitor Hook-up, DVI/VGA/HDMI?

I think it's time to retire my aging samsung 22" and buy a few 23" LED's to replace it.
My graphics card only has DVI out (x2), and the 3 monitors I'm looking at do not have dual DVI (either dual HDMI and DVI, or DVI/VGA/HDMI), so I would need adapters from DVI to HDMI/VGA. I'm guessing that's all handled at the adapter/hardware level, so linux should have no problem finding them, but if I'm hooking 1 up natively to DVI, and the other through an adapter (or both through adapters), will I notice any quality difference between the 2 monitors?

Personally I use my HDMI monitor as my main monitor and have the secondary monitor attatched to VGA. I can't really tell the difference in performance between the two, however I never work with anything terribly graphics intensive.
and it hurts to hear that my Samsung 22" is also 'aging' of course so is my 17" secondary I guess maybe that'll be my next investment...
Sorry about the aging comment
But this is the answer I was looking for! I don't want to have 1 monitor hooked up via HDMI and the other VGA and be able to see a noticeable difference between the 2. I don't do anything graphics intensive either.
Thanks for all the responses!

Waiting to buy ... do I .. DVI, VGA or HDMI? (Samsung 23" TV)

Hello,
I'm currently very near to buying the basic Mac Mini model, customized to include;
1.83GHz Intel Core 2 Duo
120Gb HHD
1Gb RAM
My question is, I have a 23" Samsung HDTV and the ports on the back are HDMI and VGA with audio. I know the Mac mini comes with a DVI to VGA adapter but am wondering which is better for my situation, and why?
Also what type of cable would I need for the better option? Currently I have none. I have a 3.5mm jack audio cable, which has the same male connector on both ends. Would I need any of the following to get setup:
DVI to VGA cable?
VGA to VGA cable?
DVI to HDMI cable?
I'd rather not use Apple's adapter, if possible. I've found straight connections to work better than through an adapter of any kind.
I'm trying to get everything ready, so that when it does come, I can simply plug in and use straight away, without having to go out and buy a cable before hand
Thanks for your help and advice,
R-Fly

Since no-one has replied so far, I'll throw in a thought or two:
It might help if you post the model number of the TV, such that those with experience of it, or the opportunity to do some digging, can let you know whether the HDMI option is suited to your needs or not. However, you can be pretty sure that the VGA connection will work just fine, since by far the most common complaint has been with minis which do not correctly get ID from the display when connected via HDMI.
In your situation I wouldn't be so much concerned at using an adaptor - there's no reason to think they would not work perfectly well as long as they are firmly connected. Certainly I've used both DVI/VGA and DVI/Composite adapters with Mac minis for quite some time and not experienced any problems.
