CMoney Level 1 Level 1 (10 points)
I have a PowerMac G4 (Digital Audio) and it has a video card with ADC and VGA ports. I would like to have it use my TV as a monitor. The TV is a 4:3 aspect ratio. I am not sure of the resolution that it can do but anything will be fine, I just want it to view videos that I have on my computer.

How can I accomplish this?

Any help appreciated

Mac Mini, Mac OS X (10.5.1), intel Model

    Neither ADC or VGA are easily amenable to conversion to TV. you would be better off finding a video card with an S-Video output.

    What resolution is a North American SDTV able to do?
  • Forrest McElfresh1 Level 5 Level 5 (4,115 points)
    NTSC is 525i including Vertical Blanking Intervals ( approx. 480i viewable ) so nominally 640X480, but don't expect pixel perfect resolution from a TV.

    isn't ADC easily convertible to DVI, from there I can just buy the Apple DVI to RCA adaptor.

    No. ADC to DVI adapters don't pass analog video signals, and even if they did, the graphics card would have to be designed to work with the video adapter.

    You can use a VGA to video converter (on the graphic card's VGA port), such as

    this is a cheaper suggestion than the new video card, this costs about $50, the card was looking like $90

    How much should a video card with s-video out cost?

    I've looked on Newegg, but I'm not sure if they are compatible with the Digital Audio

    There are two video cards that are (or were) recently in production that are compatible with a Digital Audio, The Radeon The Radeon 9800 Mac Edition and the Radeon 9200 Mac Edition.

    The 9800 is AGP and would replace your existing card, since there is only one AGP slot. It Requires OS X for video acceleration and costs $210 here.

    The 9200 is PCI and could be used in addition to your current card.
    It costs around $120. It works in both OS 9 and X, but seems to require OS X in Digital Audio Macs.

    If used cards are OK, most (but not all) Mac Radeon cards have TV out.

    Note: Some "Mac" video cards are actually Windows PC video cards that have been reprogrammed ("flashed") for Mac use.
    If done correctly, this can work well (I'm using one now).

    Incorrectly flashed cards can have unusual problems though, so it would be a good idea to check the return policy before buying.

    I have a Powermac G4 Gigabit Ethernet Dual 500. I just bought a Samsung 26" HDTV to use as a monitor. The TV comes with a PC (VGA) input. I connected the Powermac to the TV - VGA to VGA (using the original graphics card). The TV is both 16:9 and 4:3 aspect ratios. The computer output is beautiful at 4:3. Doesn't look very good in 16:9 - too stretched out. I wanted 16:9 so I bought the AGI Radeon 9200 Mac Edition. Didn't make any improvement. I called AGI tech support and they said that they do not make a card for MAC that supports 16:9. (They do have products for the PC). The tech support said that I should return the card - so I did.
    Anyway, my point is that the Powermac G4 works well with a TV that is 4:3.

    Good luck.

    Hi, I'm new to the forum, but I could really use some help!

    I have a PowerBook G4 15" and I would like to watch DVDs on my Samsung LCD TV. I bought a DVI to video adapter and my tv just says no signal. I was tried changing the display settings on my mac and tv and nothing has worked. I tried connecting the cables when both were on and off, and still no luck. I have an A/V cable, might this be the problem?

    I don't know if this makes a difference but I bought my computer in the USA, but am now living in Europe so the TV is European.

    heeeelp!

    Hello,

    I have been trying to accomplish something similar. I have a 450Mhz G4 with a Rage128Pro 16MB stock video card, if i purchased the"Apple DVI to Video Adapter", do i have the correct understanding that it would NOT work because it is not designed to work with my video card. Just want to make sure, as this would be a perfect $19 solution.

    Thanks!
