DVI-I Compatible?

I understand that all of these monitors are DVI digital compatible which is known as DVI-D. Though I am curious if it also analog compatible (VGA). This is known as DVI-I digital and analog. Of course, there's only a DVI input on these monitors. If it is DVI-I then I can use a VGA to DVI-I adapter (VGA male to DVI-I female), which is not a converter box. Putting it simply, I need to know if the monitors are directly analog compatible without any conversion needed. Please don't bother asking or advising about what video cards will drive them. I will probably get a 20-inch display. Though I won't be running 1680x1050, just 640x480 (480p EDTV). This is because of a Dreamcast and other VGA compatible systems. I'm mentioning this in case anybody wants to know why. Thanks to anyone who attempts to help.

No. The ACD only has the digital DVI input and will only accept a digital signal. Even if you get all the cables and adapters hooked up, it will not work with a analog VGA signal.

Searching for USB to VGA or DVI adapter compatible with linux

Hello everyone,
Since my HP mini is lacking a VGA connector (in fact, there's a proprietary one, but the cable for that is rare and expensive), I'm thinking of buying an USB adapter to plug a monitor. I don't care if the connector is VGA or DVi.
There're a lot of these adapters, but I'm not sure if any is compatible with Linux.
After a lot of searches, I still didn't find something useful.
Is there anyone who had experience with this kind of adapter or can point me some documentation about that ?

Just so I understand correctly... these USB to VGA/DVI adapters are video cards in their own right, yes? Something that I know works with Linux it the Villagetronic VTBook http://www.villagetronic.com/vtbook/index.html. It's a PCMCIA card (which is faster than usb 2) but you can get USB to PCMCIA adapters.

Mac Mini behaves poorly through DVI at 1920x1080 on HDTV displays

I recently purchased a Samsung LN-S4695D - a 46" LCD TV capable of 1080p with HDMI and VGA inputs. I've had been using my 23" Cinema Display + a Mac Mini G4 + Rotel Amp as the centerpieces of my Home Theater, and decided to change out the display to accommodate a gaming system and perhaps some other digital or component inputs (and, of course, nab a larger viewing surface). It seems like a fairly standard use of the Mini, but unfortunately many of us are running into disappointing results using our Minis as connected to an HDTV display. I'm writing here to see if we can clear up the issue with the mini and to attempt to identify reasonable workarounds or solutions until Apple gets the Mini right for HD home theater.
The current problem with the Mini and the Samsung TV/Display is that when the Mini is connected via DVI-HDMI (with a Monster 400 2m cable) to the display and asked to run at 1920x1080 (60hz NTSC) it does a reasonable job until it is required to refresh a lot of pixels (scrolling through album art in iTunes, playing DVD or other video, etc.). At that point, the screen fills with bands of static, and (if the rate of change is sustained) eventually looses the signal all together. With heavy scrolling operations, the signal returns as soon as scrolling stops, but with full-screen video it usually stays out until the mac resets its video resolution. Another article shows examples of this "DVI static" here:
http://www.freewebs.com/themagius/minidvipics.htm
So it is clear that the Mini and HDTVs don't play well at 1080 resolutions, as many of you have attested to. The samsung seems to do a better job than most with the Mini in that it it actually renders the 1080 as well as other resolutions, but flakes out on fast updates. While some other resolutions are also problematic, it is important to note that 1280x720 runs flawlessly on the Samsung, and is currently how I have mine set up (VGA input was too disappointing compared to DVI, though it scanned great and fit the image w/o over/underscanning.). Also, my Powerbook G4 1.25ghz (older than the mini) powers the Samsung perfectly at 1920x1080 as a secondary display, running DVD video or anything else that I throw at it, which leads me to believe that the mini is the problem. Here is another story very similar to mine that reports almost the same results with a Sharp LCD panel:
http://www.avsforum.com/avs-vb/showthread.php?p=5940932
So I've three sets of questions for Apple and the rest of you on this forum:
1) Why does the Mac Mini underpeform with the LCD display? The Powerbook works great, and the mini works great with my Cinema display (also 1920x1080) - where is the disconnect between the Mini and the Samsung? I understand very little about the actual details of DVI signals being carried across the wire, and don't understand what would cause the Powerbook to succeed, but the Mini to falter.
2) Assuming the Mini video hardware is at fault, has Apple improved this with the new Core 2 Duo line? Has anyone had success where previous Minis or other Apple hardware failed at 1080? If not, is there any announced intention to make the hardware that is positioned as being most ideal for the living room (ie, Mac Mini) actually DVI/HDMI-compatible with the finest HD living room devices?
3) An unfortunate sideffect of the DVI connection to the TV is that it requires the image from the Apple device to be oversanned (about a menu-bar's worth of pixels disappear on each edge) or underscanned (2" of black space around the image). Is there a common industry standard to correct this? Who is managing the overscan - the TV or the Mini? Also, can any utility, such as ScreenResX correct this until Apple manages to build in correction options into the OS for their living-room devices?
Thanks for all the help! Hopefully we can outline clear answers here in this thread for everyone else having similar problems.
Mac Mini G4 Mac OS X (10.4.8) Samsung LN-S4695D, Monster 400 DVI-HDMI 2m cable

David,
Great post. There's a lot to digest here. Let's get started!
The first question relating to noise, or static, over a TMDS (DVI) connection has to do with with the interoperability of various TMDS transmitters and receivers and how they are implemented. At this point in the market place there are thousands of combinations of transmitter/reciever pairings and obviously some are working better than others.
If you were to observe a TMDS signal with a scope there is something called the "eye" which is framed by the swing voltage and the bit time. When the eye collapses and is encroached upon, digital noise is the result. The noise margin is degraded by higher bit rates. That is why the mini and your TV are working at 720p but failing at 1080p...because the dot clock is that much higher for 1080p. The solution for cases such as this is to build a custom 1920x1080 timing that has reduced blanking, which allows for the lowering of the dot clock. Generally you can lower the dot clock sufficiently to get the noise to stop. LCD displays are relatively immune to reductions in blanking time so you can squeeze a lot out of a timing that was designed more with a CRT in mind.
To answer your second question, you can't fairly say the problem is with the mini. When you consider TMDS compatibility between two devices you have to take a whole system view. This includes not only the transmitter (mini) but the transmission line (PCB traces from the TMDS transmitter inside the mini to the mini's DVI connector -> the cable -> PCB traces from the DVI connector on the TV to the TMDS receiver in the TV), and the receiver. All three have to work together to make things come out right. You could probably just as easily find a display that works well with the mini that doesn't work with your PowerBook. It can be really had to pin the blame down to one device except in the most obvious cases where a certain device seems to be incompatible with just about everything. But I don't think the mini can be labeled that way. Compatibility is definitely an issue the industry still struggles with, especially at the higher clock rates approaching the 165MHz TMDS speed limit.
As for question 3, overscan is being forced by the TV, not by the mini. And, no, utilities like SwitchRes X and DisplayConfigX cannot be counted on to reliably deal with this except in the case of pure analog displays with magnetic deflection systems (e.g. old TVs and monitors). Once you have a digital processor involved and a matrix addressed display, tweaks to porch timings and blanking and such do not have predictable results. It seems to work in some cases but it is basically voodoo when it does. Purely luck.
If you want, I can help you to build a reduced blanking, 1080p timing that will most likely eliminate the DVI static. But you'll still be stuck with overscan. I should point out that a lot of manufacturers are starting to "get it" with respect to the public's desire to attach computers to their hi-def LCD televisions. I see a real shift in 2006 models. I believe the current crop of FHD (Full HD; native 1080) LCDs from the three "S" companies (Samsung, Sharp and Sony) all can display 1080p bit-for-bit now, meaning no overscan. So at least that is changing for the better. Write back if you want help with the timing.
Cheers. And thanks for starting this great thread.

G5, Dell 30 inch monitor, Radeon Mac9600 PRO 256MB

When I ordered this monitor, I read that my computer should have a dual-link DVI-D compatible graphics card. I had a dual-link DVI card, but soon found that the one I had didn't support the higher resolution of the 30 inch monitor. Apparently, the only card that does work with the bus structure on my G5, (which is AGP8X), is the recently discontinued Radeon Mac9600 PRO 256MB.
Since I couldn't find one that was actually in stock from the likes of CDW, I tracked one down on eBay. What is unfortunate is that while it does indeed support this resolution, there is a lot of crazy pink artifacting (for lack of a better description) that is going on all over the screen. There are also static-like lines that zip around occasionally. I am assuming that this has something to do with the card (I have now tried 2 different 9600 cards) as the problem was not present when driving the monitor with a lower resolution-supporting card.
Any ideas how to remedy this other than buying a new computer that supports the newer PCI-E cards that might alleviate the problem?
I am also wondering if I end up having to selling this monitor because the problem is unsolvable and I purchase the Dell SP2309W, 23inch, will I have the same problem because of my G5's "ancient" bus structure..?
As a side note, I have two Apple 23 inch cinema displays, both of which have gone pink on me, so I am not inclined to purchase an Apple display again.
In advance, I really, really appreciated the assistance. When did this all get so darned complicated?

Hi Steve,
Thanks so much for the response.
I originally had a Radeon 9600 128MB card which did not support the higher resolution on the Dell 30". However, when the 30" was running from the 9600 128MB until I could get the newer card, I did not have this pink artifacting problem, so that leads me to believe that it is not the cable. However, my husband is bringing one home tonight to try anyway.
I have tried two Radeon Mac9600 Pro 256 MB cards, thinking the first might be defective, and still have the same problem. So, unless both cards are defective, it is something else. I have searched around online trying to find an answer, but all I seem to find are folks mentioning the same problem (with a variety of cards & monitors), but nobody seems to offer an answer that actually solves it.
I appreciate the input regarding the smaller monitor. I thought that might be the case, but at this point, I take nothing for granted. This just all seems overly complicated
As for the other cards (nVidia 6800, and ATi's X800), I cannot seem to find one of either that is actually available for purchase - and AGP, and MAC OS X, and 256 MB, and Dual link DVI. What I have heard is that the AGP bus structure is "ancient" and that nobody is actually manufacturing these cards any longer.
The other issue that comes to mind, is that if I find one of the above cards (I think I found one on Amazon - used for $499) I could get it, and find I still have the same issue. Refer to my comment regarding other posters who seem to have the same issue with a variety of cards/monitors. I just thought that somebody, somewhere had to have encountered this and knew how to fix it or at least what it might be.

Can X1900XT power Dell U2711 resolution

I'm thinking of getting the new Dell U2711 LCD monitor. Will my old X1900XT be able to run the 2560x1440 resolution?
Someone says it requires a dual-link DVI-D compatible graphics card here:
http://en.community.dell.com/forums/t/19319486.aspx
I read the X1900XT page it says it has Dual-link DVI, but not Dual-link DVI-D. Does that make a difference?
Here's the Dell U2711 specification page:
http://accessories.us.dell.com/sna/products/Monitors/productdetail.aspx?c=us&l=e n&s=bsd&cs=04&sku=224-8284
Here's the X1900XT specification page:
http://ati.amd.com/products/radeonx1900/radeonx1900xt/specs.html

The ATI 1900 has two dual-link DVI-I ports. These ports have both analog and digital video, so can be used for any display using DVI-A, DVI-D, or DVI-I plugs, single-link or dual-link.

Hp 110-124 pc compatibility with 1920 X 1020 monitor

I just hooked up my new acer monitor g247hl full hd to my hp 110-124 desktop. My monitor only works with the vga cable. I have a dvi-d cable hooked up and went into the monitor menu and changed the input from vga to dvi. Even though I press enter to lock the dvi input setting in, it won't stay on dvi. The next time I go back into the input, it always has switched itself back to vga. Tried unhooking vga cable but then can't see menu. Emailed my IT man that I had bought a 1920 X 1020 full hd monitor. He said my 110-124 would not support full hd (1920 X1080) and that few computers would. Is he right? Is there anything I can do to make my computer work with the dvi-d cable so that I can have better resolution than vga?

Hello @thecyberthug63,
I have read your post on how you are looking to connect your desktop computer to your new Acer monitor using a DVI connection, and I would be happy to assist you in this matter!
To further diagnose this issue, I recommend trying an alternate DVI-D cable to connect your monitor to your computer. If this does not work, I suggest connecting the monitor to a different DVI-D compatible computer. This should help ensure the functionality of the monitor.
If the monitor and cord work on a different computer, please call our technical support at 800-474-6836 for repair options on your desktop. If you live outside the US/Canada Region, please click the link below to get the support number for your region.

Cables for MacPro and Dell 3008WFP monitor

I have ordered an new MacPro with 8 core processor with the ATI 5770 video card. The display will be a Dell 3008WFP.(30 inch lcd). Dell suggests "dual-link DVI-D compatible graphics card that supports this resolution" I think the ATI 5770 card works for this application but would like to know the appropiriate cables that need to be purchased. Thanks

Apple 5770 product page:
ATI Radeon HD 5770 includes three video ports: two Mini DisplayPorts and one dual-link DVI port. This allows you to connect the 24-inch Apple LED Cinema Display plus another Mini DisplayPort-based display, and a DVI-based display such as the 30-inch Apple Cinema HD Display. Display adapters are available to connect VGA displays.
*Does the mini display ports support the new 27" monitors from dell? These monitors require dual-link dvi.*
DisplayPort and Mini DisplayPort only differ in connector size. Electrically they are the same. DisplayPort easily supports 2560 x 1600 resolution.
The Dell U2711 has a DisplayPort interface.
All you need is an adapter from standard DisplayPort to Mini DisplayPort (the U2711 ships with a DisplayPort cable) or you can use a 6 foot (2m) DisplayPort to Mini DisplayPort cable. The same goes for the U2410, 2408wfp, and 3008wfp.
Also,
If you're referring to the u2711, it also has DisplayPort, and you can use a simple MDP-DP adapter instead of getting a pricier MDP-DVI converter. That's what I would do.

Projector suggestions

I'm currently in the market for a projector for use in the classroom and academic presentations at conferences. I was originally looking for a projector that had a DVI input compatible with my Macbook Pro, but now I am also considering a wireless. I have a budget of up to $1,500; suggestions?

I am looking too. I keep coming back to the Infocus IN10 it weighs just over 2 pounds, is bright and in my price range at 1250 but I would like to hear from a mac user who owns one.

Harm Millaard You're Correct

The nVIDIA Quadro FX 3800 is slower
When compared to cheaper gaming cards it dropped the Windows performance for Graphics and Gaming Graphics from a score of 7.4 to 6.9.
It's a good thing I don't play games, but it is a bit of a shock to pay at least four times more for a card to see that much lower score. However, when scrubbing it's a delight.
Having said that, I do have a couple of questions which hopefully you or someone here can clear them up for me:
- When loading the latest card driver it allocated the monitors in reverse from the basic driver which installed itself right after installing the card, i.e. the monitor plugged into the DVI-I port (identified as #1) it is shown as #2 monitor and the one plugged into the DisplayPort (identified as #2) now is the #1 monitor. The DisplayPort cable's other end is a DVI-D connector and the DVI-I port is connected with a DVI-I cable (also this monitor is DVI-I compatible). Have you encountered or heard of this? It is not a serious issue and of course solvable by configuring the display one wants to use, just a concern since I've never incountered this before.
- This brings me to my second question; is it better to use both DisplayPorts, rather than what I've done?
Thanks and Cheers,
Michael

Sometimes it pays to buy more than one needs
In this case it's an adapter cable from DisplaPort to DVI-I. These are not always readily available in my area and I ended up with two because I was concerned about delivery from one supplier. Of course having done so they both arrived at the same time...
As indicated earlier, I now connected the main monitor to the DisplayPort #2 and the secondary monitor to #3 port on the card, both of which are DisplayPorts.
Is there a visible difference - YES. Better than I expected! Color graduation from light to dark shows no banding, which was not the case with the previous graphic cards.
Although not important, the monitor sequence is now #1 and #2 for the main and secondary monitor.
One more point, when I had the DVI-I cable connected to port #1 the signal received by the monitor was in analog format, now it is in Digital format, but without HDCP... Interesting...
Cheers,
Michael

It should work, but the narrow viewing angle means it probably has a TN LCD panel, so there may be color banding, and it may be hard to calibrate.
You will need a mini-DVI to DVI adapter (and a DVI cable).

Mini-DVI to Video Adapter No Longer Compatible

This is an infuriating subject for me. I had a 2007 2.0Ghz Intel Core 2 Duo White Macbook. On a daily basis i used it with my widescreen TV. I am not made of money, so it is an old tube screen that requires a composite connection.
When that macbook decided to not work anymore, even after several repairs, they replaced it with a new 2009 2.0Ghz Intel Core 2 Duo white macbook. Of course, the higher spec that came with this seemed like i should have been grateful. No, I've just been P.O'd ever since. I can no longer use my Macbook to watch movies on my big screen as the DVI adaptor which i paid a completely stupid amount of money for no longer works. I'm sure this problem could be fixed with some kind of a patch for the NVIDIA GeForce 9400M it comes with. But i guess they have just forgot about the white macbook now. Great.
Does anyone out there know of any way around this problem? Again, i want to connect a 2.0GHz Intel Core 2 Duo white MacBook introduced after January 2009 to a composite connection as once used in the Mini-DVI to Video Adaptor. Anyone know of a solution?
I ask again for this to not be deleted like all my other negative posts. It DOES contain a question, which i very much wish to be answered.
Regards,
Steve.

I dont think you understand. Yes, it does use the same connections - it all connects up properly. But after 2009 the white macbooks no longer recognize the TV-Out when you connect the mini-DVI to Video adaptor.
On my old 2007 white intel macbook that had the old graphics card, i was able to connect it all up then go into display preferences and it allowed me to set up the screens as i wanted (ie mirrored, side by side etc). Now, under displays settings, that is no where to be seen.
Its a nothing to do with anyhting being wrong, its just known that Apple discontinued support for it. Even on the apple store website here, you will see in small print under the adapter that it is not supported on white macbooks from 2009 January onwards.
I want to know is there any other solutions.

'09 mini not compatible with mini-DVi to video adapter?

I hooked up my new '09 mini to my AV receiver via Apple's mini-DVI to video adapter but got no picture. My previous mini ('06 model) worked fine w/ the DVI to video adapter. I'm thinking the mini-DVI port on the new mini doesn't pass analog signals anymore, i.e., it's now DVI-D vs previously being DVI-I.
Anyone else have this experience w/ the '09 models? I know it works with the older models. I'm just trying to figure out if I have a defective adapter or if the '09 mini's DVI just doesn't pass analog. I noticed the supplied mini-DVI to DVI cable is DVI-D, so maybe that is a hint.

I doubt that'd work. Usually these adapters work by connecting "legacy" wires on the newer connectors to an older interface. The mac actually produces all the appropriate signals, and the adapter just hooks the wires together appropriately.
It sounds like the only analog signals the mac is producing are Red-Green-Blue signals, like you'd use for VGA or component video. It's not producing a composite video signal. So if you convert mini-DVI to VGA, the composite line is going to be dead on both.
The only kind of adapter that could help you would be one with some amount of circuitry that actually pastes the Red-Green-Blue signal into a composite signal. Something like:

Nvidia 7300GT card compatible with Apple's DVI to VGA Adaptor?

To rephrase, is the Mac Pro's stock Nvidia 7300 GT card able to support the Apple DVI to VGA connector which would allow me to connect a Viewsonics CRT? And will that card also allow me to connect a second CRT for dual monitors?
A temporary setup for a few months until I buy new Apple Displays...
Many thanks,
John

The card used with the adapter allows use of standard VGA monitors. There is always the chance that it won't, due to some irregularity, but I doubt it. Many have posted using VGA monitors and having no issues. Apple issues the adapter for your type of scenario.
