MINI DVI-DVI and Samsung 40A656 give nasty image

Hooked up like this I do have the right resolutions but the quality of the image is not very good. The display shows get characters with small lines under them also for instance the red, yellow en green buttons on top of MAC OS Windows are very rough. Let alone shadows etc.
Any idea's how to solve it ? Of course my Apple dealer blames Samsung and Samsung blames the apple!
Though I must say that I had a Mini '07 for a couple of weeks in januari and that one displayed fine...
So right now I am back to VGA which is seemingly better than DVI. A bit odd isn't it ? All cables are of normal 1,5M length
The Samsung rep. by the way mentioned a MAC driver to solve the problem "since the Samsung is a Microsoft aimed TV and should be fooled by some driver on the MAC to get things right..." (...unquote) Unfortunately he could not be more specific than that!

I see others do have the same problem as well...

You really need a newer Mac Mini with a true HDMI output, because that Mac Mini's DVI output does not support Audio.
You might try a 3.5mm to RCA adapter
from the Mac Mini's headphone jack to the TV's audio input,
but that would require being able to select the Audio input in the TVs menu while using it's HDMI input.
Optionally you could also use an external 2.1 Speaker System or patch the audio from the Mac Mini to your home stereo system to enhance that older Mac Mini's audio.

External monitor loses signal to macbook pro through DVI cable and Mini DisplayPort Adapter

Hello,
So I had my external monitor connected to my MBP with a DVI cable and a Mini DisplayPort Adapter, for a while already. But sometimes, the monitor would lose signal from the laptop and gives me a white noise screen. Now, the monitor can't receive signal at all, even after I got a new Mini Displayport Adapter. When the monitor and the MBP is connected by the cable and the adapter, the monitor would say "no signal" and the MBP screen would flicker (I think it's trying to connect to the monitor, but can't). The new Mini Display Port Adapter also makes the screen flicker, so I'm not sure if it's the problem is at the adapter or the DVI cable. I'm pretty sure it's not the monitor.
What do you think? Have you ever have a screen flickering problem when your MBP is connected to an external monitor?

I have had the same problem. By following your suggestions I got to arrangements. I could not send them off to the side. When I hit the mirro disply key everyting worked. I got it solved by clicking in arrangements and setting displays to mirror display.
I am still have a problem of no sound coming through my tv.

Mac Mini and Samsung 43" DLP HDTV gets Black Screen Only

Just bought a new Mac Mini with great anticipation for some large screen viewing.
After numerous attempts the Mini has yet to produce anything but a black image with the occasional red or white horizontal line on my 43" Samsung DLP TV. Not even a brief grey start up screen. Just permanently black.
Here's the kicker: I do get a great computer screen image on this 43" DLP TV in Mac OS 8.6 off my ten year old Macintosh PowerPC. (The trouble is it's a noisy older computer and has no bluetooth for wireless mouse & keyboard: and no Front Row with remote control)
I have the VGA cable connected to the "computer in" port on the back of the Samsung DLP TV .
This is with the exact same cable and connection that refuses to work with the Mini.
Earlier attempts at using the DVI port were unsuccessful so for now I am staying with what works on the older Mac.
Some other things I've tried:
-with my Mini hooked up to a 17" CRT Samsung monitor I have tried all available resolution settings at 60 Hz, reconnecting to my large screen Samsung each time, producing nothing but the black screen.
I've tried turning the TV on before the Mini and vice versa
I always check to make sure the PC connection is selected on the TV
As well, I have re-installed the OS onto the Mini to eliminate any possibility of a sofware conflict from data transferred from my Emac
After consulting an Apple technical page (article 303406) regarding Black Screen issues and Mac Mini on large screen HDTVs, I went into single user mode and changed some text as specified. That did't help either
So far I have never seen a grey startup screen at all, only a totally black screen.
Someone in a recent post here or on MacMini.com touched on impedence issues with signals into VGA or DVI ports. The Mac Mini operates on low voltage. Could there be some connection to how strong a signal it produces compared to my old PowerPC with its ATI graphics card?? And just why would that make a difference
I haven't seem my particular issue addressed in this forum or on MacMini.com
Thanks for any help
Mac Mini 1.83 Intel Core Duo 512 Mb Ram Mac OS X (10.4.7) Emac; 604e PPC with G3 Upgrade & ATI Video Card

Just finished testing the Mini remotely with the use of the Redstone software recommended by BSteely in a previous post. Fun Stuff.
I saw the Mini "desktop" on my Emac screen and could control it remotely, even though the mini was connected to the large screen Samsung.
But the "fix" did not progress from there. When I called Apple for further help they were not able to help me tweak my Mini. Apparently there was nothing to tweak.
A second level Apple technician finally told me (after a few calls to both Apple support and Samsung) that this Mac Mini is likely not capable of producing a screen image on my large screen Samsung.
He said the Mini supports "Coherent Displays up to 154 Megahertz and Non Coherent displays up to 135 Megahertz". On his recommendation I checked with Samsung (second tier) and they are not sure exactly what that means. Same here.
Samsung did reply that the "pixel clock (of this HDTV) is 74.2 Megahertz". Again, too technical for me.
The latest second tier Apple guy just told me said that my Samsung 43" DLP is probably not compatible with the output capability of my Mac Mini.
Bottom line
It's all about the output capabilities of the Mini's "Intel Extreme Graphics GMA
The Mini's video output is not upgradeable like the other mac which works with this HDTV.

Using Cinema Display and Samsung LCD with One Mini

I have been trying unsuccessful to output the DVI of my mini to my 23" Apple Cinema and my Samsung 4669F (native resolution of 1920x 1080p). I have tried various methods including using the Gefen 1:2 DVI Splitter (Ext-DVI-144) and a DVI-HDMI cable to the samsung in conjunction with SwitchResX, all to no avail.
Any help?- I wish to mirror the same display on both LCD screen simultaneously?- However, I would settle for a solution of a convenient A/B switch? ANy tips?
What about an external USB video card for the Mini- that should work too?- any tips?
I used SwitchResX because I determine that because the 23" ACD was 1920 x1200, the Samsung was not displaying because the Gefen splitter box was sending the same signal in 1920 x1200 to the Samsung, which was not accepted by the Samsung whose native resolution is 1920 x 1080p. However, once I switched the resolution to 1920 x 1080 to force an out of the mini to that resolution, there was no display at all on the 23" ACD and I had to do a safe mode reboot to recover the display on the 23" ACD?-
One would think that it would be relatively easier for Apple to create a script that would allow a person to display 1920 x 1080p on the Cinema Display, a script that overrided the message from the ACD that tells the mac mini to stretch any resolution to 1920x1200 before it gets to the 23" - This way I could use SwitchResX and the Gefen splitter to output 1920x1080p to both displays at once (of course the 23" ACD would have to have some black borders on the top and bottom. Why doesn't apple make this available? - Spent $900 on this monitor and the Mini has a DVI output- why should the Gefen splitter be rendered useless simply because my other display is a different native resolution.

Mini DVI - DVI adaptor

This may be a stupid question but...
I have to do a presentation and need to connect my MacBook to an external monitor for the first time. I was told that they have a fifteen pin video cable to plug into my computer. Is a Mini DVI - DVI adaptor what I need?? Also, do they have these at Best Buy?

Hi,
Yes, you need an adapter. I was surprised that the Macbook comes with that strange little non-standard video connecor. I'll give Apple a criticism on this point, requiring me to both spend additional money for a converter dongle and have yet another thing in my presentation kit to get lost or accidentally left behind when I use my Macbook in a lecture hall.
I'd say, fine, go ahead and put the oddball connector on there, but also be presenter-friendly and give us a standard VGA connector. Every media-enabled lecture hall I've encountered at a university or hotel has a VGA cable hanging off the podium.
Be sure you get the correct adapter. There are three types: DVI, VGA, and S-video. They're all about $20 each from US suppliers. I'd recommend going to a computer store to be sure you get the one you want. Web sites often don't have adequate descriptions ofthe adapters to be sure you order the one you need. That's over-priced for what you get, but you have no choice.
This reminds me of the old powerbooks that had that weird mini-DIX connector instead of an RJ-45 Ethernet jack the rest of the civilized world was using.

Mini Displayport DVI Adapter Problem

I'm currently having issues with my MacBook Pro's DVI out (via Apple Mini-Displayport Adapter). Whenever my displays go to sleep (which is set after an hour) and wakes up, sometimes the external display (a SyncMaster 220WM) shows "snow" or "static" ... basically what you'd see if a TV station had no reception. If I let it sit for a minute, the second display will return (the MBP's primary display is fine, no errors of any kind). If I power off the Samsung display, the MBP treats the connection as if I pulled the cable out and reverts to a single screen setup. I have been able to reproduce this by using "Hot Corners" to sleep and wake up the displays. I'm using the 9600m GT as the computer is my desktop replacement. I never had this happen to me before with my older MBP with an 8600m GT using the same DVI cable and display. I think it's the mini-displayport adapter. Is this a common issue. Anyone else having these problems.
Thank you!

I have been experiencing the same flickering problem when using the mini Displayport output on the GT120 to drive secondary monitors at my office. Using a Monoprice cable instead of Apple's adapter provides a more stable signal, but we still get intermittent flickering where the screen goes black for a second, then a full image returns. I think this issue is due to massive loss of signal strength via the mini Displayport output on the GT120 card. Hot Plug Detect is also weak which points to low signal strength. This might be fixable by increasing the output voltage of the card slightly to boost the signal strength. Apple really should just issue a firmware/BIOS fix for this problem since the implementation of mini Displayport on these cards seems poorly engineered. Does anyone know how to do this?

New Mac mini and Samsung Tv

Dear all,
A little help please. I have just purchased a mac and mac mini. I would like the I Mac to run as the master and the mac mini to work on the tv downstairs.
The mac mini works when connected to a monitor however when I try to connect it to my tv my screen is black.
I am currenlty trying to connect via pc connector lead as there was nothing else in the store so I am connecting via mini dvi adapter to DVI cable to female connector to pc slot in the back of the tv!
And its not working.
I have downloaded chicken of the VNC onto the I Mac and have installed some program called Display config X. however whenever I plug it in it doesnt seem to want to play.
Any thoughts or should I abandon the pc connection on the tv!

I have a mini connected to my Samsung.
I have a miniDVI to DVI adapter that came with the computer linked to a DVI to HDMI cable.
I've since learned you can buy a miniDVI to HDMI cable, thus eliminating the need to the connection, which is probably a good thing.
In any case, if you can go into the HDMI slot instead of the PC slot, you will likely have better results.
This is my second Samsung TV. The first one actually had a DVI in to begin with. But it was smaller than my iMac screen, and I needed binoculars to read it from across the room.
I also had to do an adjustment to get the menu bar to display properly. It was a rescan or something. Search the forums for my name and Samsung and you will find it.

Apple MiniDisplayPort to Dual DVI adapter and 30" displays

Hi all,
I just purchased a DoubleSight DS-305W 30" display only to learn it doesn't work with the Apple MiniDisplayPort to Dual DVI adapter. I had the flickering issues described in length here:
http://store.apple.com/us/product/MB571Z/A?mco=MTY3ODQ5OTY
I thought it was the adapter firmware issue, so I drove 3 hours in the snow to the Apple store to get a replacement with the new firmware (1.0.3). After doing so, the issues persisted.
I am now wondering if anybody has experience with other 2560x1600 monitors and this adapter. I am considering buying a NEC LCD3090WQXi-BK -- has anybody tried this one? Thanks in advance.

My apologies for reading your mail after almost 2 years !
Perhaps my reply may still have some relevance after 2 years. I am using HDMI to DVI connector to connect my Mac Mini Mid 2010 to Samsung XL2370 Monitor.

New Macbook won't send DVI signal to Samsung 226B LCD monitor

I have the mini-DVI-DVI adaptor going into a Comprehensive DVI-D cable that goes directly into my Samsung monitor. My monitor won't show any signal from the Mac. I went nto Display and "calibrated" the signal but i never see a signal on teh SSung.

Sorry I didn't see this thread before or else I would have jumped on it.
The question is when, if ever, did you update to 10.5.5? Before or after you noticed the problem?

Connecting to a Sony TV via Mini DVI - DVI

I have an older iMac 20" Intel core duo with the ATI Radien 1600 graphics card and bought a Mini DVI - DVI adapter and a DVI-D cable to connect to my Sony KP57WV600 projection television using the DVI input on the back of the tv. Well, after hooking everything up, my iMac still doesn't notice the tv as a display (or anything for that matter). Yet when I turn the tv on or off with the comp on, the screen on the mac turns blue for a breif moment. So some kind of signal is being transfered to the computer but no go for the use of a display. I've asked people on a few sony tv forums but they say to ask a mac expert. I've read others that have connected this tv via DVI to their PCs but have yet to find anyone that has done so with a mac.
Please help me.
Thanks in advance,
Nick

hey there xav_101 & welcome to Discussions
there's no way to directly connect 2 mini DV cams to your Mac & i'm not aware of any software that will do what you ask. if i were you i'd get an analog switcher w/ S-Video in & out, send output from switcher to the projectors using a distribution amp & also send to a VTR. the VTR could be a mini DV cam that converts analog to DV & send that into the Mac. i suppose you could use an analog>DVl device like a Canopus 110 instead of a cam to convert video out of the analog switcher to send to the Mac. i also use external mics(2 for an overall stereo mix of a musical performance) &/or take a board feed & a small audio mixer to get good, clean signal(no cam noise) into the cam/VTR/convertor.
when i've done a multi-cam shoot i've used 2-3 cams for shooting, an analog switcher & another cam to record & convert, then input to my Mac, or just record onto the non-shooting cam like a VTR, then dump that into my Mac later. mostly for short programs up to an hour. i do a bit of editing. maybe replace/add something 'cause i record onto my shooting cams as well, add credits then burn to DVD.
i know you didn't ask but anyway... for editing i've also just shot w/ as many cams as i need/have(up to 4) then dump footage from all cams into Final Cut--i've used both Express & Pro versions. it can take a little bit of tweaking to get everything lined up & synched, but that's part of what it does well, using multiple Audio & Video tracks.
good luck, hope this helps.

Macbook mini-DVI - DVI - HDMI not working with My 32" Vizio

Okay so my Macbook mini-DVI - DVI - HDMI is not working with My 32" Vizio. I've connected an 18 pin plus one slot DVI to HDMI cable to my 32" Vizio HDTV, this cable is connected to my macbook via a Mini-DVI to DVI cable, this one has 24 pins plus one slot on the DVI side. My Vizio display is blue, no signal, it reads. I'm wondering if the reason it's not picking up the display is the lack of pins on the DVI to HDMI or because I dont have any display options aside from screen size and color on my display menu. BTW I hit the detect display button and nothing happened.... I know I just wrote alot here but hopefully someone will read it and come to the rescue. thanks

Oops, I guess all I had to do was restart my macbook. I feel like an idiot.....all is well.

Problem trying to connect mini-dp dvi to HDTV

Hi, i just came home all happy from buying a mini displayport to dvi, had all the cables set but it seems its not working... I dont know if i have to do something but as of now can´t see anything in the tv.
I´m using the mini displayport to dvi and a cable that is dvi-d single link to hdmi.
Might the cable be the problem? do i have to press a button in the mac? i´m totally lost here.
Thanks!

I know certain devices require an HDMI connection to work. Part of the implementation of HDMI was to try and curtail pirating by digital copying, so many devices look for a "handshake" in order to function.
I have personally just purchased a new MBP, so I don't have personal experience with what you are trying to do yet, but I did get a Mini Displayport to DVI adapter and we have a DVI to HDMI cable at our church. If I have time I'll try it out to see if it works or not and let you know.
I do know that my Mini Displayport to HDMI adapter I just received this afternoon from monoprice.com DOES work on my Panasonic plasma TV. For $10 it might be worth getting instead of wasting time troubleshooting what you have.

Using the mini DVI - DVI cable with HDMI LCD screen?

Hi,
I bought the apple mini DVI - DVI connector to connect my imac to the back of my plasma. I have a 3 meter DVI cable to extend the mini DVI - DVI connector.
It worked fine but the plasma is not so good for my purposes as i am using the set up to display images.
I have just bought an LG LCD TV for a very good price.
However the LG LCD does not have DVI socket! It has HDMI.
Is there a cable available that is DVI (female) - HDMI?
And will this work in theory?
Any advise is much appreciated...
Thanks

Hi Network 23,
Im not sure what you mean exactly?
Which adapters and cables are you using between TV and Mac?
My PowerBook and MacBook Pro have a DVI port, so I start there. I guess you're starting from the DVI port at the end of your adapter cable. At this point we both start from a standard DVI port.
From there I attach the DVI-HDMI adapter I linked to earlier, and then between that and the HDMI port on the TV, I use a simple, inexpensive HDMI cable also bought at monoprice.com. While you could also use a DVI-HDMI cable, I chose to use a DVI-HDMI adapter so that I could use standard HDMI cables, since I anticipate buying more HDMI components in the future.

Mac mini, macbook + DVI to HDMI + projector = No soup for you!

This is driving me nuts!!! I have tried 3 different macs, 4 completely different cables/adapters and they all do exactly the same thing.
1. I connect the mac to the DVI to HDMI cable and/or adapter combo, then connect to the projector
2. I get 2-30 seconds of wonderful projector screen usage (it works, picture looks crystal clear)
3. Then POOF! No projector signal, though it appears mac recognizes the projector.
I can repeat from 1 using a different adapter and/or cable and I get exactly the same results, but if I re-use the same cable I used previously, I get no signal at all.
What the $%@! is going on here??? Is Apple black-listing my cables or something??? I'm using everything from cheap-o cables to $$$ cables with exactly the same result.I run this projector with absolutely no problem from a dell desktop via DVI to HDMI.
For what it's worth, I'm connecting to a LG HS201 projector.
using Core-2-duo macs either with pure DVI or mini-DVI

DVI to HMDI is not supported on the Core 2 Duo Mac Mini.
You need to connect via DVI or VGA to your projector.
I have had Core2Duo Mac minis working with Sony LCD TVs and a Toshiba Plasma via DVI to HDMI cables with no problems. Obviously audio has to be run separately. There have been many reports from others that this works. It should do since both DVI and HDMI support HDCP and both are digital video connections, this after all is why a simple DVI to HDMI cable works.
What can be an issue is if your trying to do things like 3D or YCbCr colour encoding. However standard video works fine. Another common issue is if your are switching inputs to the TV perhaps via an AV Receiver or if the TV is allowed to sleep or be turned off, in these cases the Mac can see the handshake signal disappear. It is for this sort of situation Gefen makes the DVI Detective+ and the HDMI Detective+.
Since in your case the common factor is your projector and not the computer or cables it might be it at fault. Early HDMI products did have HDCP handshaking problems.
People have been using Mac minis as media center computer with HDMI for ages since the Mac mini is small and quiet, this probably goes back as far as G4 models let alone Core2Duo models.
