32" Samsung LCD as monitor -- no signal?

Hey now. I have an older G4 that I want to hook up to a 30" Samsung LCD (max res: 1280x720), but when I set it all up, there is no picture. The G4 has an ADC out, so I use a ADC-to-DVI adapter, a DVI cable, and then a DVI-to-VGA adapter to go into the LCD TV. (I was able to hook up a PC to the LCD via the same DVI cable with a DVI-to-VGA adapter and see the desktop.)
I did hook up the G4 to my 23" Apple display and lower the Display settings, but to no avail. Maybe they are not low enough?
Any help would be greatly apreciated.
PowerMac G4 Mac OS X (10.4.8)

The ADC to DVI adapter is not passing the analog signals needed for VGA. You need the ADC to VGA adapter, then a VGA cable.

32" SAMSUNG LCD not able to display Macbook through VGA Cable

New 32" Samsung (LA32A650 series 6) not picking up signal from Black Macbook. It's connected via VGA cable (mini DVI to VGA). Using a 5 meter, 15pin VGA cable which seems to work on a 20" DELL monitor (Macbook to Dell Monitor).
The Macbook sees the Samsung but the Samsung does not see the Macbook. Tried having both mirroring on and off...no luck. The PC option on the Samsung is still greyed out. Anybody have any other suggestions? I see in other posts where people are able to display their Macbooks to even bigger LCD's using a VGA setup so it must be possible.
Yes the Macbook is plugged in.
Yes cables are connected correctly.
Yes the Mini DVI to VGA adapter works fine.
I know with some PC laptops you press Function F5 (or other F?). Anything like that for a Macbook?
What's the ideal display setting for the Macbook? I've dropped the display setting all the way down to 800x600 but still no luck. Maybe I'm doing something wrong or doing it in the wrong order?

Ok...just an update.
I brought a pc laptop and my macbook to the store today. The 32" samsung LCD in the store did not pick up the signal on either laptops. HOWEVER. We hooked it up to a 42" sony LCD and no problems with the PC or macbook. So, the Mini-DVI to VGA adapter and VGA cable are fine. A samsung service tech will be coming to the house next week. I will post their findings.
My suggestion so far would be bring your laptop and cables to any store before making a decision on which LCD you would like to purchase (that is if you care to use the LCD as an external monitor).

Using DVI - HDMI cable output to Samsung LCD TV

For some reason, i have been using the DVI -> VGA Adapter with a VGA cable outputted to my new Samsung LCD TV, with resolution 1920x1080. I purchased a DVI -> HDMI Cable, but the quality/resolution is subpar to using the VGA Cable, it seems as if the resolution is upscaling itself, but according to Display Preferences, it is outputting at 1920x1080i, When i'm using the VGA cable it just says 1920x1080, without i or p.
Anyone know why?

I've been trying to communicate with a Samsung LE40A656 via a DVI-HDMI cable.
I think there must be issues with HDMI on that model because the TV can't detect a signal on the HDMI port and the MPB can't see a monitor.
But I have managed to get full screen via the Apple DVI-VGA adaptor and the D-sub port on the Samsung using the specification in this archive thread:
http://discussions.apple.com/thread.jspa?messageID=6400626&#6400626
Before I upgraded my TV I had a cheap(ish) Hyundai Vuon with a DVI port which worked fine with my MBP.
Would still like to know why HDMI doesn't work on the Samsung.

Late 2009 Macbook aluminium Output to Samsung LCD (SyncMaster 710T) problem

Have bought a Mini-Display port to DVI cable for connecting macbook to the Samsung LCD monitor. Output is fine but if i left my desk (with macbook on), and when the Macbook goes to power saving mode or sleep...after i switch it back on, my lcd display flicker and fails. It too fails to get signal at times...am I experience a weird problem?
or there is in fact some fault with my macbook?
or my LCD problem?

Anyone encounters what I am experiencing now?
I noted that there is an update for the Mini-Display Port to VGA.
What about DVI??

How do I connect my iMac to my Samsung LCD TV?

I want to connect my 2009 iMac, Mac os x version 10.5.8 to my 2008 Samsung LCD TV, model LN32A450C1D. Does anyone know what cords I will need so I can watch videos from my computer on my TV?
Thanks.

Your mac has a mini display port so you'll need to adapt that to HDMI on your TV. I have a mini display port to DVI that I bought from the Apple Store, then a DVI to HDMI adapter. Be aware that this will only carry the video signal, you'll need seperate audio cables to carry the audio signal. You can buy adapters for cheap but I've read of some people having problems with no name adapters working with their Macs, so I spend a few more $$ and shop at the apple store.

Trouble connecting Macbook to Samsung LCD TV

Hello,
I tried connecting my Macbook to my Samsung LCD TV (through a DVI to HDMI cable) but I only got a black screen and "No signal". The macbook detects the Samsung and even displays "SAMSUNG" as a detected display.
I checked the TV manual and there I found "Don't connect a PC or laptop computer to the HDMI/DVI connectors (it will result in a black screen)"
Does anybody know why? Any solution?
Will this happen with a MacMini too? I had the intention to connect it to my TV and use it as a media center

Sorry to tell you that DVI does not support sound. You either have to use a HDMI cable (with the appropriate adapter) or tap your audio output port with a 'Y' type cable configuration for sound.
Ciao.

Macbook Pro to Samsung LCD TV

I'm trying to hook up a MacBook Pro to a Samsung LCD TV (Model: LE40A656A1FXXU) but when I connected it up the message on the screen was something along the lines of 'mode not supported'. Can someone tell me what I need to do? Currently I'm using the external monitor connection on the MacBook Pro to the PC input of the TV.

I recommend not going this route, the exchange did nothing as I expected, with nothing else to try I figured why not.
After calling in about the issue after they had replaced the old macbook they told me that the "apple engineers" were working on it and to just wait out for that to happen.
Also new update,
Computer recognizes the TV when I have MDP->VGA->VGA cable 6'->TV VGA input (but the TV does not recognize the macbook)
*The TV* recognizes the macbook (only) when in addition to the above configuration I connect a 10' VGA extension cable. The would seem to be a resolution but I say the TV sees the macbook but now the macbook can't get the driver info from the Tv and there I am stuck with 1024x768 (stretched).
There is one way trick both devices into working and that is to plug in the MDP->VGa adaptor connect the 6' VGa cable to the MacBook can get the info from the TV. Leave the adaptor connected to the computer and remove the VGA cable from the adaptor assemble the combination of the 6'and 10' cables and then plug it in and it works fine.
Kinda of a pain though when you have to do this everytime you connect the Macbook to the TV.
I really hope apple can get this driver straighten out ASAP.

Connecting my old iMac G4 to my Samsung LCD TV

I have an iMac G4. The monitor went out years ago and I have been using an external monitor via the display port and adapter. The resolution on the iMac is set to the highest available on the display preferences. The monitor has always worked fine; however, I thought I would connect the iMac to my Samsung LCD TV (it's a few years old - 5 Series 1080). When I connect it to my TV via the "PC" connection option and select "PC" as the source, I see the splash screen (gray), but when the OS boots my TV says "Mode not supported." Anyone have any sage advise for me . . . I would love to utilize my old iMac for renting movies from iTunes.

TVs have very specific resolutions, and your iMac predates widescreens in anything but movie theaters. So long story short, since your iMac can only mirror your built-in (well, attached in the case of the G4 models) you basically have a choice. Either the monitor runs at a resolution the TV can support, which is probably going to be 720x480, you get a special converter box, or you just come to the conclusion most do, and decide it's really just not worth the effort.
If you had one of the newer iMacs where it's either a native 16:9 resolution or you could at least set an independent resolution, this would be much easier. As it is, you're pretty much screwed, sorry.

Connecting powerbook g4 to samsung lcd le32 r7

does anyone know how to connect a powerbook g4 to a samsung lcd le32 r7. At the moment im using a dvi to vga adapter. The mac can see the tv but the tv cannot see the mac. i have tried different modes on the tv and different screen resolutions but none seem to work. The adapter works fine with a normal crt monitor is it worth buying a dvi to vga cable or does anyone know how to get it to work via dvi hdmi?
powerbook g4

I would use a DVI to HDMI cable, and you'll have to use a separate audio cable also. A number of people on Amazon have recommended http://www.monoprice.com/products/department.asp?c_id=109 as a good cable source. If you look in your Samsung user guide, I think you'll find that S-video doesn't support as high a resolution as HDMI.

Samsung LCD TV... Need a good Digital Antenna?

I have a 46" Samsung LCD HDTV (Model #LN46C670). We just purchased an RCA Multi-Directional Amplified Digital Flat Antenna to try and pick up our local channels over the air. I followed the installation instructions to the letter and made sure the settings on the TV were correct but we were still unable to pick up any channels. Anyone else had any luck with digital antennas? What are some of the brands/models you have successfully used with this TV or one like it? Thanks in advance for your help!

Understood... all thing are releative. So I guess my first question would be... Is there a way to know for sure whether or not signals are available at my address? If not, what would be the best internal Antenna to use for testing this? An then of course there is my original question... What digital antennas have others used with this specific TV and had success?
There is no difference between a digital antenna and an oldschool analog one whatsoever. It's all marketing BS. The ONLY change to antenna requirements with the digital transition was that antennas no longer need to cover the old 700 MHz TV band - but the performance gains obtainable for redesigning an antenna to not cover those bands any more is so negligible that no one has done it to my knowledge.
http://www.antennaweb.org/ - You can put your address in here and determine what size class of antenna you need. Also, don't bother with RCA antennas, they're crud. Similarly, nearly all antennas with built-in preamps are crud. I haven't seen a single one that published noise figure specifications for their preamp, which says they have something to hide. In most cases they don't even publish specs for the gain of the antenna itself.
Note that the above site can sometimes be inaccurate if you have oddities in your local terrain. Also, if your antenna is indoors, the construction (materials, etc) of your home are important as is whether the antenna is on the side of the house facing the TV stations.

New Mac Mini, Not so new LCD HDTV Monitor, no mac support

I have been attempting to set up a Mac Mini with a Maxent LCD 26" HD TV I can't get either the RGB or DVI-D input to accept signal. I have purchased DisplayConfigX and SwitchResX_X. Maybe they could work, but I can't get a signal to stay on long enough to change the settings as listed in other posts. I have tried booting in safe mode as DisplayConfigX instructions suggest. But still only am able to see the screen until gear starts spinning with apple logo, resolution changes spontaneously to one that I suppose is unsupported and I get the unsupported display and a beautiful blank blue screen. I tried manually inputting the resolutions the monitor manual lists, while connected with an lcd pc monitor. But I can't get the Maxent LCD TV monitor to stay on. It appears that if I could get the Mac Mini to send this resolution signal to the Maxent I would be able to delete any unneeded settings and that would be it.
Perhaps Tom Fussy can help me.I have been at this for over two weeks now. So I have become super frustrated. Of course Maxentusa.com offers no Mac support. But state that if Mac mini is supposed to work with PC that it should work with my Mac Mini. My LCD TV is about 6 months old I could still return it for maybe a Sharp Aquos, if that $300 dollar more TV would work. I am happy with the Maxent otherwise. Keeping it, and having it work with Mac Mini Is my choice. Of course Apple offers no support for the Maxent monitor and directed me here. This is my first discussion group post. School me if I have not followed the rules completely.

I was able to get the settings for Maxent using Gregory's software to force 640x480. Here are my settings

Powerbook with Syntax Olevia 23-inch LCD TV Monitor

Hi there,
I got a 23-inch LCD TV Monitor from Syntax Olevia and somehow it doenst work with my powerbook.
The thing is when I connected it to my windows laptop, it worked just fine, I should say perfectly instead. Then I tried it on my Powerbook 12-inch, the Mac recognized the display, there was a VGA display on but when I turned the display on, it says 'NO PC SIGNAL'. You know, I'm ****** !
I have been on the phone with Syntax Tech Support for an hour, then with Apple for another hour, they suggested me to do everything try to get it works, everything they could find, everything within thier knownledge.... COULDNT CHANGE ANYTHING!
So the last thing the Apple guy suggested me is post a topic question here, to see what everyone says and if somebody out there has got the same problem, please do reply so, even you got it worked or not, just reply so I can have some experience. It might be compatibility problem but I don't know, not with a monitor I would say.
So here the LCD name and brand:
- Olevia 23-inch LT23HVX by Syntax.
I would appreciate for any answer, I'm looking forward to it.
Thanks all
Powerbook G4 12' Mac OS X (10.4.5)

Hi,
I'm not familiar with that monitor, but its resolution might be higher than your PowerBook can handle. I have a first-generation 12-inch PowerBook, and it seems that it can't run any of the Apple Studio monitors currently being sold. If that monitor can display a resolution of 1024 x 768, try that, as your PowerBook can certainly handle that resolution. Another thing to try is to see if you can find a friend or coworker who has a similar PowerBook (or any other Mac), so you can try connecting the monitor to that machine to see if there is a similar problem. If no Mac can drive it, you would probably have a good excuse for returning the monitor.
Hope this helps,
Ken

Sound for Dell LCD TV/Monitor?

Thanks for answers in advance. I am sure this has been answered somewhere but cannot find it.
I just converted to the dark side and purchased a Mac Mini. I hooked the Mini to a Dell 23" LCD TV/Monitor. Instead of ordinary computer speakers I want to use the speakers on the TV.
What do I need?

I am running the same setup you are, except its a 19" Samsung TV and I have it hooked up via VGA. Next to the VGA port there is a port labeled "PC AUDIO". This allows me to run a dual sided 3.5mm audio cable from the audio out port on the mini to the audio in port on the TV.
There should be something similar on your Dell, but I am not sure. Look at the back and in the user manual to see what kind of ports there are.
Here are some 3.5mm cables:

Unable to play video onto my Samsung LCD TV when using a Memorex Mini Soundbar MA5004. Anyone can help?

Does anything go to the TV? Like can you hear audio?
Dod it ever work?
Does it work with other display devices?
You are using an app that supports TV out?
What does the soudbar have to do with it?

Connecting a Macbook Pro to a Samsung LCD TV. Can anyone tell me where to find information on what I need and how to do it?

I want to connect my 2009 Macbook Pro to my Samsung LCD TV. I am afraid to go somewhere and ask and get bogus information so am putting it out here to see if anyone can help with the how tos and the types of cords/adapters I might need to purchase.

You might profit from a visit to a Minneapolis Apple store. With a brand new Mac, I think they will be most helpful - not just with transferring files, but with other advice as well. And I strongly recommend you invest in a back up drive. The Apple folk can help with that as well.
