DVI scan converter to DVI HD-TV?

I have a DVI based HD-TV that only has 1080i/480p and is 30". My problem when I hook it up via DVI directly to my Mac, is that there is always both a horizontal and vertical overscan. What's the cheapest scan converter that offers pixel by pixel adjustments on both vertical and horizontal that I can get the maximum resolution on my HD-TV? I have a 1.5 Ghz Powerbook G4 (the one released before the sudden motion sensor hard drives).
By the way I've tried Display Config X and SwitchResX, and neither seems to work too well for me.

The cost of present scan converters is too much to even consider it. Also in another thread I was told that the picture would be significantly distorted on my CRT.

DVI scan converter for under $1000?

I've just gotten some e-mails which indicate DVI scan converters are downright expensive. Considering many DVI HD-TVs are now well under $1000, you'd think that you could get a scan converter for less. Sure there is DisplayConfigX and SwitchResX, but they are complicated to setup, and it appears not all HD-TVs respond well to them. So here's the question, anyone know of a simple DVI based scan converter that will reduce the picture so that all four sides of the screen which are overscanned on my set actually appear on my HD-TV? I don't want to have to step down to VGA just to do scan conversion. Right now the VGA scan converters are only $200 to $300 depending on where you look. Why some companies charge as much as $12,000 for DVI versions is beyond me!

there are scan converters that do the simple job of converting a signal from 1 format to another then there are converters (scalers) that are designed to take NTSC (or PAL, SECAM, etc...) material and upconvert it to a higher resolution. back in the day when we used to deal with $50,000 9" gun CRT front projection systems, they often used $30,000 boxes that did the scan conversion. with CRT based systems on a large projection screen, you can actually see the black gap between the scan lines of the electron beams. the original reason to upscale NTSC video to different formats (differente VGA resolutions, really) was to increase brightness, not increase detail... for the higher the resolution, the smaller the black lines in between the scan lines on the screen. the reason that this is not so easy to accomplish is because film, which was originally shot in 24 frames per second, is being asked to play back on a device that is 60, 80, or higher frames per second (the vertical refresh rate). when dealing with film, you are of course dealing with people who are very critical with all technical processes being applied (rightfully so) and the same with the viewers. when done incorrectly or without proper processing, this scan rate conversion is visible by "rips" or jittery motion artifacts during playback.
because more and more of today's modern sources are digital (DVI and HDMI) and the display devices are also digital (LCD, DLP, and plasma) scan converters and scalers are somewhat obsolete. it is still downright confusing, though. 1080i from an HD-DVD is played back at 1080p. 1080p from a Blue Ray player is played back at 1080p. HDMI, while supposed to make life simpler, actually has a whole list of incompatible sources and display devices with more HDMI #.# versions to come.
i retract my statement, scan converters are no longer obsolete, they are just packaged with the display devices and sources so there is no market for them. a 480p DVD player with DVI out does not really give you a 480p output direct from the 480p MPEG stream. the video DSP takes the MPEG, internally outputs 480i, then the built in converter processes it back at 480p. seeing how these DVD players are very cheap, there no longer is a market for affordable scalers. you now have the all or nothing scenario where the only vendors alive rely on high end clients that want to pay for the best and not settle with what is bundled.
anyways, some of the companies still in the business...

Need to convert mini dvi to s video to run a school's Hatiachi ceiling mount projector. What is the proper adapter?

Need to convert mini dvi to s video to run a school's Hatiachi ceiling mount projector. What is the proper adapter?

Check the projector and see what kind of input is has, most have a VGA connector, so you would need a male to male VGA. You will also need the Mac mini dvi to male VGA (of course).
Some of the older projetors have a component in only, which is the red,yellow,green, RCA connectors, which are avaialable. (Usually the are fairy short, 5 ft or so, so you would need to get a VGA with yhe mini DVI to VGA, and a component (the one with the 3 RCA's) you will probaly have to get a Female to Female VGA adapter to connect te VGA to the component.
And finaally if that weren't enough, the really old projectors have only a composite input. All I can say about that is "the hunt is on"
Best of luck

2008 MBP -- DVI out -- DVI/HDMI converter -- HDTV ?

Hi guys,
I'm gonna go ahead and apologize in advance if this has been asked before, I'm having a bit of an emergency.
The backlight on my 2008 MBP (model A1260) has gone out -- I can still somewhat see the screen but it's extremely dim. I'm wondering if I can buy a DVI/HDMI converter and run the video out to my HDTV. Are there any extra supplies I'll need?
Also, any instructions for enabling the HDTV as my external display would be greatly appreciated as I'm barely able to read anything on the screen in its current state.
Thanks so much!

Convert to DVI

Hello to all, I would be grateful for any advise on my 17" Monitor. I originally purchased two Apple 17" displays 3 months apart and have been using them on my G5 2.0 with a ATI 9600 Pro 64 meg video card, (1 DVI and I ADC port), with no problems. I purchased the Apple DVI to ADC converter to use for duel display. Again all was fine.
I have now up graded both Monitors for the G5 to LG 22" DVI-1 connectors, and wish to use the 17" Monitors on either my PC with a ATI Wonder Card (DVi VGA) or with the Apple DVI converter to my MacBook Pro.
Currently only only one will convert to DVI. The other displays as best described as one looks at the screen as Negative! just like a Negative Photo film.
The interesting thing when I connect this Monitor directly to the G5 ATI ADC port (no conversion) it's FINE!
If I try to use the DVI port (convert it) it displays the Negative view look! I am baffled but obversely something has failed which seems to point to the Monitor.
Any feed back or advise would be more then well revived. Cheers DH

DV-Video to DVI Converter

Dvi miniport with dvi-hdmi converter

When using my dvi miniport. I have a dvi->hdmi converter. I was wondering how I can make the sound go trough it?

Open System Preferences>Displays and make certain that you have checked the box titled 'Detect Displays'
Your TV Manual should have instructions for connecting a computer. Some TVs have several HDMI ports. Make certain that you have selected the correct one.
Ciao.

DVI/HDMI converter for a Samsung TV

Curently I have an ATI Radeon HD 5770 1024 MB on my Mac Pro, and on FCPX I manage 3 monitors (two 24" and one 22" but all 1920X1080 resolution) and all is fine.
Now, I was thinking to sustitute the 22" one with a 32" led television Samsung which has Full HD 1920 x 1080 resolution. So all should be fine. My doubt is: Samsung TV has HDMI in, so I have to go with a DVI/HDMI converter. Could this cause any problem??

You can get a simple cable that is DVI on one end, and HDMI on the other. I've used these several times in the past.

DVI / ADC Converter Display Issue

Hey all, any help would outstanding. Picked up a Radeon 9200 (PCI) for my G4 Dual 533. Running it to a an older 17" Studio Display. Had to score the DVI/ADC Converter. But here's the problem, when I plug it all in, I get no image on my monitor. Have tried taking my old GeForce 2 out when I try it, leaving it in, etc.
The S-Video out works fine and I can send to a TV no problem. Have all most recent updates for the Radeon card and OS X.
Any ideas? Appreciate it!

In the link I gave, one person was using the Gefen adapter, but the power supply was getting VERY hot. Buying the Gefen adapter and a new, bigger, power supply, would be the easiest way to get things to work. The only cable cutting would be moving the cable from the Gefen power supply to the new power supply. That would just be a two wire cable. If you can find the matching plug for the Gefen power supply, you wouldn't have to use the Gefen power cable, but make your own, which is probably better because Gefen might be using wires too small for the extra current.

Challenge with scan converted computer footage

Not sure if this is more appropriate for the Encore forum, but I'll start here. I recently created a short video for a client that incorporated a computer screen showing the client's software in action. The screen displays lots of small text, columns of numbers and some waveforms. I captured the output of the computer via it's DVI output using an Image Pro scan converter. Capture was at 1920x1080p. I created the video in 1920x1080p using After Effects and Premiere. I then created a Blu-ray and a DVD. On the Blu-ray, I think the computer screen looks great. My issue is with the DVD. I outputted an MPEG2 DVD file, first at CBR8 and then CBR 9. On DVD, the computer screen suffers considerably. Much softer and hard to read the on-screen text. I realize I'm downscaling quite a bit, but I'm wondering if there's any way I can get a better image? The piece runs just 3 min 45 sec, so I have lots of room on the DVD. Any and all suggestions would be appreciated. Thanks in advance.

I'm afraid that what you're seeing is likely as good as it gets using the current workflow. A 1080p HD video has FIVE TIMES the pixels of NTSC DVD. Computers send uncompressed digital RGB graphics straight to the computer monitor. With NTSC video, the brighter, more saturated colors that look great on the computer display may be "illegal" or out of range for NTSC. Fine details and once vibrant colors turn to mush, in large part due to the lack of resolution, but also due to the NTSC color system and the lossy MPEG-2 compression of the DVD format with 4:2:0 color.
Once thing that might possibly help is rather than using a scan converter, use a screen capture software such as Camtasia or similar - that will offer a higher quality to start with. The captured "video" should look identical to what you saw on the computer screen and you'll at least have something that matches the computer quality to start with. Another idea - it's a given that you're going to lose the fine detail/small text when downscaling. How about setting the computer resolution to something closer to 720x480 and re-capturing the computer graphics, using a larger text font and such that would better lend itself to SD viewing.
Does the video HAVE to go to DVD? That's just a terrible medium for computer-based material. I've used Camtasia screen cap software in the past and made presentations to be viewed ON a computer, and the resulting "video" looked as sharp and clean as the original computer screen, no loss! These type of files can be distributed electronically, avoiding the cost of DVDs and packaging for such a short project.
Good luck, I've been in this position myself.
Thanks

Scan Converter for 7300

Hi
Im looking for a scan converter to support the 7300. The units I'v googled seem to accept DVI-D only. Will these work with the 7300 which (I think?) is DVI-I.
An example is the TVOne C2150 http://www.tvone.com/c2-2100-2150-main.shtml
Has anyone found a good scan converter for these cards?
Cheers
Nick

DVI-I contains all the DVI-D signals plus the analog video, so it can run a DVI-D device. a DVI-D plug may be missing some pins, but will plug into a DVI-I socket.

Does Mac Mini's HDMI-to-DVI cable support analog DVI monitors?

The Apple website shows that the new (late 2012) Mac Mini comes with an HDMI-to-DVI adapter cable in the box :-)
The DVI video connector standard supports both analog and digital video signal modes, but not all models support both modes.
I have an old PC monitor with a DVI connector, which is probably analog only. Will this work with the new (late 2012) Mac Mini?
In other words: does Apple's HDMI-to-DVI adapter cable support all DVI monitors, or only those with a digital input?
Many thanks!
- Martin

Your right about the DVI standard support both analogue and digital. The three types are
DVI-A (analogue only)
DVI-D (digital only)
DVI-I (supports both)
In this case the HDMI to DVI adaptor will only support digital DVI. This is because the HDMI port only supports digital.
Generally monitors with a DVI port support digital DVI, if you compare the socket and pins layout on the monitor to the one on the Mac adaptor if they are the same layout then that should indicate the monitor indeed supports digital DVI.
Note: The maximum resolution supported by the Macs HDMI port is 1920x1200, if your monitor supports a higher resolution then you should get a Mini Displayport to DVI adaptor or if needed a Mini Displayport to Dual Link DVI adaptor (for the highest resolutions).

Run MDP to HDMI for picture. Use a cable like this to run sound from your audio out on your Mac to your TV's audio in. That's about all you can do.

Female dvi to male mini-dvi cable?

I bought the wrong cable from apple (happens sometimes), had it too long to return.
I have a mini-dvi to s-video cable which I needed a dvi to s-video cable instead. is there a female dvi to male mini-dvi cable that can make it useable?

never mind. was the right cable. wrong computer.

I have a MB Pro that is running Lion; I also have two external DVI monitors and a DVI splitter in hopes that I could run the two monitors with my MB Pro. This actually works fine, but I am unable to "extend" the desktop. Any insights?

You cannot have a extended desktop using a splitter. All that does is mirror the pair attached to the splitter.
You can do this however using a Matrox DualHead2Go.
Other solution would be to attach one monitor to your video out as you do the splitter and attach the other via USB (assuming the adapter supports the monitor's resolution).
