VGA signal output type mDP-VGA adapter

Howdy.
Working on a way to plug our new mini (early 09) into a crusty ol' analogue tv, whose best quality input is up to 576p component. Tv manual say to plug component source (either YPbPr, YCbCr or Y B-Y R-Y) into the component input on the tv (Y Pb Pr).
My understanding of signal types is limited, and I am looking at a VGA to component converter as my first preference option since svideo and composite are so crusty.
Can anyone be really specific on the exact type of signal output from the miniDP-VGA adapter? As far as I know, most computers output a vga signal referred to as RGB, which SOME tvs can read via component in. Can anyone tell me if this RGB equates to any of the above signals (such that i could simply use a vga-component cable that I already possess), or if i will definitely need to get a converter box? I have plugged my older mac mini into the tv (using dvi-vga adapter supplied and then vga-component cable i purchased form some dodgy online ebayer) and had no luck.
can anyone tell me the potential ramifications of messing around with this stuff? Can inputting incorrect signals damage any of my hardware?
does anyone have any brilliant ideas on how to run an early 2009 mac mini into a tv via component? At this stage it is going to cost me around $200 for a decent converter box , and being a younger generation I want a solution ASAP and would prefer not to wait weeks for shipping from the States.
It seems as though the new minis only do dvi-d, while my older one has dvi-i - this is why the dvi-video adapter is not compatible with the early 09 models. i have spoken to apple tech support several times but it seems as though they are getting their dvi types mixed up and don't understand my predicament fully, as their suggestions are not possible with dvi-d. Is there such a thing as a DVI-d to DVI-I adapter? Would it make any difference?
Any clarification people have to offer on this one would be greatly appreciated.

A few comments; first off, you can't damage a TV with wrong signal types, although some old TVs can be damaged from wrong timings. That's going to depend a lot on the TV's age whether it has a more modern, multi-sync type chassis or not.
The Mini DVI output on the new mini is DVI-I. That is how it is able to support the Mini DVI to VGA Adapter that Apple sells for the new mini. But you are right it no longer supports the Mini DVI to Video Adapter. But that is an issue with drivers and has nothing to do with the mini having a DVI-I output or not. But it is definitely Mini DVI-I.
So to connect a component converter box, you could use either the Mini DisplayPort or the Mini DVI output of the mini. I would tend to recommend the Mini DVI as being somewhat more standard. However, a Mac really wants to see something called a plug-and-display driver, which is also known as EDID, whenever it is connected to a display. So try and see if you can find a component video converter having a VGA input that has an EDID loaded into it or else the Mac will not be happy and it could all be money down the drain that would have better been spent on a new TV.
Hopefully you will get some more specific information from someone else. Good luck.

Does Mini Displayport to DVI adapter support analog VGA signal?

I'm just about to buy a macbook pro. Since the MDP (mini displayport) to DVI and MDP to VGA adapters are £20 a pop, I can only afford to get one. Obviously DVI is better in general, but VGA supports more older hardware, CRTs, and the spare VGA input on one of my displays (where the desktop uses the DVI).
What I'd like to know is does the MDP to DVI adapter also support the analog VGA signal on certain pins (like most physical desktop DVI ports do)? If it does, since I have about 3 or 4 DVI to VGA adapters lying around, I can get the MDP to DVI adapter and use the DVI to VGA adapters with it if necessary, but if it doesn't I might be better off getting the MDP to VGA...

No. Unlike DVI, which in the DVI-I configuration has both digital and analog pinouts, DisplayPort (and mini-DisplayPort) are purely digital. Mini-DP to DVI then DVI to VGA will not work. If you look carefully at the Apple Mini-DisplayPort to DVI adapter, you'll notice it's a DVI-D connector - digital pins only.
The Apple mini-DisplayPort to VGA adapter contains a digital-to-analog converter.
So, you'll have to choose. If you want VGA, get Apple's mini-DisplayPort to VGA adapter.

Is it possible to force the Macbook to output a VGA signal without EDID

Im an audio visual integrator and I'm constantly running into this issue that if the mac doesn't have EDID present it will not output VGA signal. Quite often we will convert VGA inputs to just RGBHV (or 5BNC) to run to a display or projector. Normally this works fine with most laptops but unfortunately not macs. I've used things like EDID minders in the past to get around this issue but I'm hoping there might be a way to get around this on the software side.

No, the video card cannot be exchanged - you have a pretty decent GPU there; not sure why you'd want to switch it out. You can upgrade the RAM to a maximum of 16GBs. Apple recommends upgrading in matching pairs, so I don't really think I'd try 4GB and 8GB stick.
Both Crucial and OWC have memory available for the new Macs. Both are reputable dealers and know Macs well and I would only buy from these sources (and I would buy Crucial, were it me).
Although your Mac didn't come with a users manual outlining the installation of the additional RAM, you can download the late 2011 model users guide as the models themselves are almost identical.
Good luck - write back with any questions.

Ipad vga signal levels

3 out of 5 attempts to present Keynote (and other video enabled apps) presentations have failed. After some investigation I discovered that the failed talks (ipad could not drive video projector - iapd couldn't find project, and projector couldn't find ipad) were result of long cable lengths between projector and VGA connector that I plugged into dock-to-VGA adapter. These were 50' long cables in conference centers. I rustled up some more standard length cables after these very embarrassing failed attempts to give public presentations, and with shorter cables everything worked properly. I should also mentioned that numerous MacBook, MacBookPro and PC-types laptops all had no problem whatsoever driving VGA through a 50' cable.
Anyone else experience this problem? It makes it impossible to trust the iPad as a conference presentation device if iPad video signal levels are too low. Perhaps I have a defective iPad, or is this a systematic problem?
If I have to buy a VGA signal booster to carry along with an iPad, its absurd since these devices are nearly the size of the iPad itself!

I am not sure of what the official limit is, but a google search brought up 50' as the "practical" limit. Another site said 9 meters. I have seen some long vga cables in various conference rooms.
You may have an iPad with a reduced output. You could either try another ipad, if you know of one available, or take your ipad to the Apple store and see if an expert can test the output strength.

Concerning: VGA monitors using an Aluminum Powerbook G4 PowerPC 2004 15"-screen 1.5Ghz
The DVI (converted to VGA) video output stopped working on this computer after 9 years of service. This raises question 1:
Is there any way of fixing this? I've tried the usual: triple checked all vga cables & devices through trial & error. Bought a new DVI-VGA adapter. Reset PRAM, PMU, etc. Nothing works. Something is probably damaged, because my KVM switch was not working unless I hot-reseated the vga cable into it, leading to this DVI port, and that is pretty rough stuff.
Question 2 (related):
This dovetails into this: Can I drive a VGA monitor with the s-video output port on this computer. It would take an s-video (male)-to-15-pin-VGA adapter. Has anyone does this? So far, I haven't even found the adapter mentioned anywhere.
Thanks for reading this.

Thanks for the useful feedback, Knucklesmac. I agree. I must have blown something on the logic board -- because I had a faulty old KVM switch that would not switch between computers without some nasty hot-plugging/unplugging the VGA video cables. (wince!). It's like when Dizzy Dean ruined his arm because a line drive hit him in the foot and he readjusted his mechanics around the injury. I take the blame because this has been a great computer, and does not deserve any blame.
If it will help anyone else reading this thread, C2G (née Cables to Go) has some interesting ideas for still getting external video out of this computer:
-USB-to-VGA
http://www.cablestogo.com/product/30545
-Convert s-video or composite video signals to high resolution VGA
http://www.cablestogo.com/product/40971
The price range is $75-$85, which doesn't make horse sense to me for such an old computer -- which has a lot of life in it anyway, because its own 15" monitor is not chopped liver.

Quality issues with VGA port on Type 2504 docking station

Hi,
I see quality issues on the VGA output of the Type 2504 docking station with a T61. The monitor image is blurred, not much, but enough to be irritating. When I compare the DVI output with the VGA output on two equal NEC MultiSync LCD 2170NX monitors it is a clear difference. If I connect the LCD monitor to the VGA output of the T61 itself, the picture is clean. I have tried both monitors with different cables in different configurations and also adjusted monitors manually, and my conclusion is that it must be the VGA output of the 2504 that generates the un-sharpness. I have got several 2504 docking stations from the IT department to test and all attempts show the same unsharp picture on the LCD connected to the VGA port of any 2504. Recently a colleague got a new laptop and docking station. He also used DVI and VGA on the old setup and had no visible difference between the two monitors. His new setup is a different T but his new dock is also a 2504. Now he has clear difference between his monitors. He also tried several 2540 docks and cables but the difference is still present.
The unsharpness is not immediately present when just looking at a dual head setup. But after a while it becomes tiresome to look at text, specially black on white, on the monitor connected to the VGA port. There is a slight shadow on the right side of all letters. When looking at non-aliased fonts, they look as if aliased on the VGA connected monitor. Already aliased fonts tend to "smear" and I have the unpleasant feeling that my eyes are not focusing correctly.
My question is: Is there a different VGA DAC on the docking station, or are the analog signals just wired through from the laptop VGA DAC? Older IBM docks do not have this problem, we have a lot of them at work in dual head configuration with DVI + VGA to compare, and we only see this problem with the 2504.

VGA is an analogue signal... so it can be affected by the quality of DAC chip used by the GPU associated electronics, the quality of connectors on the vga out and dock (that is why good analgoue audio equipment use gold plated stuffs) and the quality of copper wire and shiedling used in the cable (i.e. Low Oxygen Content Copper wire).
The above is general description for all people to use <---- so please don't feel offended if i repeat something that is already said.
There is NO conversion electronics on the dock per se, they are just passthrough, so no conversion.
I guess the problem lies with improper shielding somewhere. I have the same problem with my T61/60 and dock and my T40,41,42,43 on five different docks.
So i have ended up using lenovo usb2dvi converter on T61 and have two dvi output and bypassed the vga altogether.

What type of vga cord should i use?

I just purchased a mac mini and it is on its way. I have a 22'' memorex lcd tv and it has a VGA plug in. What type of vga cord should i use? Theres male to male and theres male to female. Which cord should i use and does any1 know a site i can order it off of?

the first site that came up...

these cables would allow you to hook up the monitor without using the adapter... would just save a little bit of space if depth is at all an issue, or the visibility of the cable sticking out that far back.

How connect a 27 cinema display to HP Pavilion with VGA video output

how connect a 27 cinema display to HP Pavilion with VGA video output

If it is a thunderbolt version of the apple 27" display, you don't. The TB displays can only work with a TB source.
I also think you are out of luck with the mini-displayport versions of the apple 27" as well. This would imply converting an analog VGA output to a digital input of the 27". I suspect that there is not enough data supplied by VGA for that to work and I do not believe any adapters exist for this.

Vga signal booster

can you buy a vga signal booster to allow the mac mini to work on any crt monitor?

It seems to me it would be better and make sense to just buy a computer that actually worked right out of the box without needing a VGA signal booster. Wait until next week to see what new stuff Apple releases at Macworld.

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!,
Joe, Mpls

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.

Computer Will Not Start, No DVI or VGA Signal, Beeping

My desktop HP was working fine until recently. I want to buy a new graphics card, so I took off the side of the tower to check if I have a place to install the new graphics card. Before I could do anything, I had to leave home, so I replaced the side of the tower. I DID NOT touch anything inside of the unit at any time, I only touched the side. Now, when I try to turn the computer on, the screen says that there is no DVI or VGA signal and the computer beeps at me (short, then long). I disconnected the cables from the back of the computer and reconnected them, and I cleaned off the fans,which didn't fix it. I looked up the beep code, but nothing seemed to make sense to me there or help me at all for that matter. I have no clue how to fix this! Please help!

Error while trying to assign an output type to medium external send in smar

Hi,
My requirement is to send a smartform through e-mail as PDF attachment.I have made the changes in the print program of the smart form.When I try to assign the output type to the medium external send in vt02n transaction,it is being saved but it is showing the status as 'not processed'.When I check the processing log it is showing 'Please maintain a output device in your user master data'.But I am able to send the mail and open the attachment.When I try to assign the same o/p type to medium special function,this is being successfully processed .Why am I getting error when I try to assign theo/p type to external send?

Check the logic in the entity adapter ENT_Prov_Permitted_Resources.
This adapter is causing problems when you are trying to assign the resource.

Regarding the 'Dispatch time' settings for output type...

Hi Experts,
May i know what 'Send with application own transaction' means when we configuring output type in SPRO for 'Dispatch time'.
Cause i knew if we set it as 'Send immediately', then this output type will be triggered upon saving the orders.
But i dont know what that item for..Could you kindly help me on this...
What it means if we set the dispatch time as 'Send with application own transaction' for delivery output..??
Thank you very much.

Hi,
If you choose 'Send with application own transaction' when maintaining condition record for output type,during order,delivery and invoice saving the output type signal is yellow,that means unless you select that output and trigerred for printing it will not goto the spool.i.e in simple words the output is for manual printing.......
Let me know if you need any clarifications on this..
Regards,
Chandra
