I have a older mac mini, 1.42ghz, and am trying to get it to see my Sony LCD hdtv. nothing seems to work. I have tried dvi to hdmi, and also vga to component and always a black screen.

When i use my powerbook G4 with the dvi-hdmi cable it's perfect and no problems.

I have displayconfigurex and have used all sorts of resolutions, the built in hdtv, standard def, etc. but still just a black screen.

anybody have any luck with Sony LCD hdtv's and the mac mini.

Very frustating since the powerbook works so well and don't understand why the mini is so dumb in seeing the tv... I may just try to apple video adapter but I will only get lower res standard tv, and not widescreen resolution.

The sony model is KLV-32M1

Hmm. I did a very quick search on the net and came up with this from Macintouch.com

Quote:
Recently I tried to connect a G4 (1.42ghz) mini to my 32" Sony (KLV32M1). I got a DVI to HDMI cable from Radioshack (12', $35). When I connected -- no picture. After messing with monitor settings with System Prefs I downloaded SwitchResX and tried some more. No picture at all. So I sent e-mail to Sony support. Here is the answer:

Thank you for contacting Sony Online Support.

We regret the difficulties you are experiencing in connecting your Mac
mini to the Television. The Sony KLV-32M1 Television is not designed to
be used as Macintosh Mac mini monitor.

When video is output from a PC, or ANY digital source, to a TV, there
will be black bands at the top and bottom of the display. When viewed
the TV screen will be too small to allow the entire display to be viewed.

Since the hardware and software in the PC systems is designed primarily
for Digital video input and output, the only way to have completely
viewable video output to a TV would be to replace the digital video card
in the PC system with an analog video output card or to convert the
digital video output signal to analog.

This would correct any Bands, however this would not solve any
resolution issues.

A card that is designed for TV to a PC hook-up for laptops and computer
aided presentations would be the only solution. Sony does not
manufacture such a card. Please visit your local computer store or contact the
manufacture of your Mac mini unit for product information.

NOTE: The HDMI input available on the Television is designed for use
with high-definition video equipment such as cable and satellite set-top
boxes, DVD players and recorders.

Thank you for the opportunity to be of assistance.

Your Sony Email Response Team

This doesn't seem to jibe with other MacInTouch readers experiences.


This doesn't help you at all, but it's the only bit of info i can find..

While I got the mini 1.42 to work with the Apple video adapter, it's not the ideal, so I think I will upgrade to the newer intel mini soon, which seems to be more friendly to HDTVs and digital inputs (at least I hope so with my Sony...)

One thing I did do though was download the ATI driver software. This actually has more controls for the monitor to control sharpness, color, etc. Helps to get the best out of the analog Apple video adapter. It does improve the analog video picture.

Almost zero manufacturers officially "support" using their HDTVs as a monitors for a computer. That is the same response you would get from Sony for most any HDTV model.

Also, getting an Intel mini to resolve the problem just seems like you'd be solving the problem of fitting the square peg into the round hole by getting a bigger hammer. Unless you have evidence of the Intel mini working with this TV, you may end up having exactly the same problem. That said, since your Powerbook works with it, the Intel mini is probably a reasonable guess at a solution.

If I had to guess, the issue is related to the G4 mini's coherent/non-coherent TMDS timing issues. Take a look at the suggestion at the bottom of this thread for a suggestion on how to use SwitchRes X to set up a custom timing.

Im using a Mac Mini dual core with my Sony Bravia 32" LCD.

I found a very acceptable timing for this combo.
(Using the HDMI input with a DVI > HDMI cable)

Download the application DisplayConfigX tot set the following parameters:

Timing:
Horizontal / Vertical
pixel / lines
1208 / 680
144 / 24
80 / 5
216 / 41
which makes a total of:
1648 / 750

Untick the "interlaced" box

Set the refresh rate to:
Refresh rate 59.992

This gives you an overscan of about 4 pixels around (so you can actually see the menu bar), a geometry of 16x9, and an amazing resolution.

Please let me know if you were able to tinker a better resolution.
This TV should do a native 1368x768, but I havent been able to get that working.

Sony customerservice really is a pointless excercise for this kind of thing.
(Understatement; it actually sucks bigtime)

Greetings, Tony
