Scanlines with DVI-out

Hi,
Like many others I'm a new switcher and my experience with Mac has been good all along so far - except for this one thing; My external monitor is behaving quite strange since I began using it with OSX (formerly used with Win XP). The problem is that all the mid tones are covered with faint horizontal lines (about 2-3 pixels high). First I thought it might be a hardware defect on the monitor but when I installed Boot Camp and installed XP it all worked flawlessly again. I've been adjusting the color and display settings for a while now but there's still no improvement.
External monitor: LG L204WT (20", 1680x1050)
Please,
Any help would do since I really don't know how to solve this.
MacBook Pro 15" 2,4Ghz Santa Rosa Mac OS X (10.4.10)

Hi
If the graphic card of the notebook DOESN`T support DVI (Digital Visual Interface) standard and can NOT convert analog into digital signals. That means: it can not be integrated into multiport connector of your notebook.
I dont know how old is the unit but I think that this model is about one and half or even two years at the market and you can not expect the same picture quality that can be given by newest units with much better and powerful graphic chips. Please dont be mad on me. It is just my opinion.
Good luck!

[GeForce PCe] Help with TV-out and DVI on NX6600 PCI express

My NX6600-TD256E doesn't give me any output on TV-out (S-vid) or the DVI. The VGA is okay.
On my old Radeon card you had to switch the TV-out on in software. On the NX6600, I can't find anything in software to let me do this. Should the TV-out work all the time or does it need enabling somewhere. I've been through every tab on the Nvidia driver in the system tray and the display properties. The manual doesn't cover my card but a similar model and the screen shots are different.
The DVI doesn't work if I go DVI from the card to DVI on my monitor. The Card is DVI-I and the monitor is DVD-D. I would have thought that this should work. If I use the DVI out through the VGA adapter to go DVI from the card to VGA in on my monitor it works, but this just means there is an analog signal coming out the DVI.
Any help?

Not sure about your card but with most geforce cards, you have to go into the nvida control panel to enable tv out.

Clear enclosure 23" cinema display with DVi connector?

Hi all,
I went to a local Mac store (Not Apple) where I was shown a supposedly 23" HD cinema display (clear enclosure) with a DVI CONNECTOR directly built in. I was under the impression that all clear enclosure versions natively came with the ADC connector and that if DVI was warranted, a converted was necessary. To my surprise, Apple apparently made two clear enclosure versions, both ADC and DVI. I've verified under the spec. area of this site. But, there were no 23" clear enclosure with DVI, except of course, the current 23 version which is the aluminum. So, was the more likely scenario that this rep. had shown me a 22 with DVI or is there really a 23 version with DVI. I was convinced at the time myself that it was a 23 clear enclosure version with a DVI connector. I saw with my own eyes that this display did not have a converter connected and it looked like the 23 as opposed to a 22. The 22 & 23 looks so similar and can be mistaken for each other. One of the ways of identifying readily is that the 22 has the power/brightness controls near the bottom right of the casing. Could someone confirm either way. Thanks!

Hi-
I agree that the rep probably showed you a 22" DVI model. See page 8 of the 22" Cinema Display Manual for the cabling of the display.
You will see the DVI version of the Cinema Display listed in this article. The article was put out prior to the Aluminum housed ACD release.

Dvi out screen size

I've attached my macbook (leopard 10.5.5) to my Samsung LE26R73BD LCD TV via the mini-DVI to DVI adapter and DVI to HDMI cable.
I can see the desktop on the TV but the outer edges of the desktop are "off the screen". The preferences finds the monitor and notes it as Samsung and selects a default resolution. If I adjust the resolution it makes no difference the problem remains.
Clearly the macbook can identify the LCD TV and the Samsung is receiving and displaying the screen from the macbook.
I can find nothing in the Samsung's menus that resolves the issue. There is a zoom and alignment option but the amount of the edge that is "off screen" is too large to adjust with the TV options.
Has anyone experienced this type of issue. If I use the VGA adapter to connect it displays the screen correctly. Why the difference between the VGA and DVI? The LE26R73BD is older technology now, but it is HD ready. I am keen to use the DVI rather than the VGA to get better picture definition.

Welcome to Apple Discussions:
The DVI input is purely digital. The VGA is analog. With VGA, the settings for the TV set are automatic because there is a single standard for VGA.
With DVI there are many standards, may resolutions, scanrates, etc.
On my Sony Bravia, there are many menu settings for compatibility. The computer does its best to detect the best resolution etc on the monitor, but for older monitors, you may need to set the vertical/horizontal/refresh rates manually. If there are not an option, then there is not much to do.
You can play with the resolution setting on your Mac, that might work.
What resolutions does your Samsung display? Most Digital TVs today include the standard 480, of course, 720 and 1080.
If you TV erroneously detects a resolution, it will display improperly. Does your computer just detect a generic Samsung? Or does it actually list your model number?
It's not clear what "HD-ready" means. There are older HDMI standards and specs that may be the problem. The TV and computer "talk" to each other but if there is some error in the signals, then it won't work properly.

Z97M GAMING no hdmi signal with DVI converter

My monitor has VGA/DVI only (Samsung SyncMaster 213T), I have a HDMI to DVI converter in the DVI port, this works with the HDMI out from my laptop.
Am putting together a Z97M/4790K rig. I get no signal at the monitor from the Z97M's HDMI out, if I connect it to a TV I do get a signal.
Am using the same (short) HDMI cable and adaptor with both the laptop and the new Z79M, used the same cable to connect the Z79M to the TV.
So the cable and converter are good (they work with the laptop) and the Z79M HDMI port and cable are good with the TV.
Anyone have any idea why the Z97M HDMI output wont display on my monitor? (Any bios settings to make the HDMI signal more compatable?)

Yes, to be clear, there is no GPU. When I say the Z97M's HDMI out I mean the output from the Z97M motherboard. I have tried it with a second screen, the TV (it worked).
Logically one of two things must be happening... either the Z97M's HDMI signal isn't making it through the DVI/HDMI adaptor (when the laptop's signal is), or the monitor cannot process the Z97M's HDMI signal (when it can process the laptop's).
HDMI and DVI signals are the same, so the adaptor is just a plug converter ('square plug in round hole') and unlikely to be the issue, especially as it works with the laptop.
But both the monitor and laptop (which work together with HDMI and the DVI converter) are >5 years old. The Z97M is very new and could be it's HDMI output just isn't compatable in some way with the (relatively) old monitor.
Hence am wondering (for example) if there are any Z97M bios settings which might make it talk nicely to the old monitor.
Be interested to hear if anyone has had issues (or even success!) using the HDMI out with DVI monitors, especially old Samsung SyncMasters ?

Cant use DVI-D port with DVI-D cable from Pav 500-100a to HP W2207 monitor

I have a new Pav 500-100a factory standard with no mods. A HP w2207 monitor.
Currently connect fine with VGA to the DVI-D port with the adapter that came with the pc. I've setup Windows, updated to 8.1, put in my files from my old PC and all was well except video isnt that good.
I got a DVD cable form work but its a DVI-I cable. It took 5 mins before windows comes up and then whenever the background picture changed in the theme it hung for a few seconds. I read that I need a DVD-D cable which i purchasd today.
The packet says its a CL-DVI2M - DVI M/M 24+1 CABLE 2M. The tech in the shop says its a good calbe and will work fine.
When connected and I power up I get teh hp logo and rolling dots then it goes blank.
I reconnect teh VGA cable and its all fine - using the VGA to DVI adapter.
I ran msconfig and turned of safe boot - restarts and comes up fine in safe mode. I set the resolution to 1280x800 and restarted and reconnected the DVI cable - blank again.
If I put the VGA cable back in it boots fine. The monitor has been factory reset and seens the DVI connection but Windows remains blank. Also tried booting first with no cable - connect teh DVI and the monitor remains in sleep - power reset teh monitor and still blank also shows no DVO conenction.
I fI power up with DVI connected I can get to BIOS, and i see the HP logo and dots as Win 8 starts.
I dont know what else I can try. I have no other usable video card with DVI
Any ideas out there?
Pls help - Steve
Although I am an HP employee, I am speaking for myself and not for HP.
This question was solved.

Hi Steve,
Only connect one active video cable to the monitor and do not use any adapters.
Use a flashlight and examine the DVI connector on the monitor. Which DVI type is it?
Some of the older HP monitors have DVI issues so you might want to check with HP Support and see if you have one of those models.
An older post a long time back indicated that audio also had to be feed to the monitor (claimed by a poster). If this is indeed true then it's a monitor design flaw. So, you could use a native HDMI cable and test out that claim.

MacBook Pro DVI-Out and FrontRow Color Anomalies

ok, so i've got one of the first generation MacBook Pros 2.0GHz processor, 2GB RAM, etc. i want to use the DVI-out to connect to my Sharp Notevision projector, which has a DVI-input. i have a standard DVI cable and when i connect, everything is fine. i can display at the projector's 1280x1024 native resolution and finder and other application windows look just fine, color-wise.
however, when i jump into FrontRow (or play any Quicktime movie or use iTunes to play movies), the color shifts and looks horrible. the glow around the icons in FrontRow are oddly red, and other nuetral colors look greenish or otherwise. its almost like you've got a component cable connected with two of the channels swapped.
the same projector works fine and displays accurate color with my AppleTV and if i connect the laptop to one of my Cinema Displays, the colors for movies are all accurate. i thought maybe the DVI cable was bad, and bought a replacement and the new cable produces the same off-color results.
any help or guidance here would be greatly appreciated!
thanks,
scott

Another update, I did some research and it seems that ATI are cagily admitting to the fact that there might be a problem with the X-series;
http://support.ati.com/ics/support/default.asp?deptID=894&task=knowledge&questio nID=26586

http://support.ati.com/ics/support/default.asp?deptID=894&task=knowledge&questio nID=25682
You'll notice that ATI tell you to contact the manufacturer of your computer if the graphics are integrated into the motherboard. Like with Apple. Much joy to be had there.
I phoned their technical support and got talking with a specialist who was mystified and suggested 'turning off the airport'.
Also, it seems that Apple rather significantly "underclocked" the GPUs in their macbook pros;

Could be running the GPUs are running on a lower voltage and maybe they're not working right, or the signal isn't stable enough to pick up an EDID? It seems to be quite a mystery. Perhaps the osx86 community will have some tricks up their sleaves for twisting the x1600's arm. Still doesn't explain why the monitor worked that one time.
This probably isn't an issue for anyone who doesn't want to plug their laptop into an external display, but I suspect it's a widespread problem just waiting to rear its ugly head, especially as HDTVs become more ubiquitous.
Anyone else struggling with external display devices, or with solutions, I'd appreciate your input.

T400 DVI Out through Mini Dock

The T400 has no DVI output plug. However with my old A31p which likewise has no DVI-out, I can get DVI from it through its docking station. Is it the same for the T400? When docked to the ThinkPad Advanced Mini Dock, will I be able to get DVI from it?

Unfortunately, according to the Specifications posted at
http://shop.lenovo.com/ISS_Static/merchandising/US/PDFs/t400_and_t500_datasheet.pdf
the T500 has DisplayPort but the T400 does not. So no digital video output from the T400 unless through docking station.
I would strongly prefer the brighter WXGA+ LED-backlit screen which is only available on the T400 (T500 only has WXGA), AND the DisplayPort that is only available on the T500.
It seems you can't get both the higer resolution LED and the digital output on the same Txxx series notebook.

MBP freeze DVI out to a monitor

When I first got my 13inch 2010 MacBook Pro about two months ago, I connected it with an external monitor via MiniDisplayport to DVI cable. And since then I had experienced random freeze, the screen would suddenly turn to light green or some other color, keyboard and everything else stopped working, and I had no choice but to reboot. However in the last 10 days I removed the connection to the external monitor and so far I have not experienced any problem. I think I have isolated the freeze issue. Does anyone know what's going on here?? Is it possible for me to reestablish the connection without experiencing any crash in the future? thx

I have the same problem. When no external monitor/TV is used, no issues ever. When using HDMI-DVI and using HDMI as sound output, freezes every 15-45 mins. When using just video, no audio, freezes every 30-90 mins.
When I called apple support, they said no known issues. I ran the low level Apple hardware diagnostics (ASD 3S138) OS and EFI, and my mac passed every single test. (DVI port is not listed on the diagnostic)
Everything is up to date, and my MBP is was purchased in August (3 months old).
My buddy has a MBP 13" from a year ago, before they added the capability to output sound through DVI-HDMI, and he has never had an issue.
This seems to be a hardware issue, and only seems to be happening on the 13" MBP with the new DVI out that allows sound that was released mid 2010.

DVI out to component in (DVCPro HD)

Repost... Sorry, accidently posted in FCE, would like to ask again here.
Other than buying the Matrox MXO, I'm stumped.
I need to capture a clients PowerPoint into a FCP HD timeline so that they can see all their transitions, then I'll use Compressor to create an HD file which will play on their digital signage box. (plasma HD screen)
I already have a successful workflow with evey aspect EXCEPT getting PP in a HD sequence. PowerPoint is on a MacBook Pro (DVI out) to a quad G5 with a BlackMagic HD extreme card that accepts component in. I've tried a scan converter that has component out, and a simple DVI to component cable. BlackMagic card sees nothing in HD.
Matrox MXO says it'll do DVI to component (Y, Pb, Pr) all day long for a grand.
I would really like to explore my options at NAB this year, but the client won't wait that long.
And yes, the signage box will play PowerPoint presentations (.ppt files) that look great right now. However, when playing a PP presentation you can not overlay an instant messanging system crawl which is a must for them. This is why the PP must play as an MPEG2 HD file.
Any help is most welcome!
--Bob

Understanding the client wants their own transitions, so there would be a bunch more work. But if you do go this way I would suggest putting a "proxy" clip of the entire show (point a camera at the original PowerPoint playback) on V1, then cover that with your clips and transitions on V2. Should make the timing a lot easier.
But it does seem ridiculous that you should have to do that at all. Maybe a post house can help with a quick translation.

Sdi to dvi out vs. dvi preview monitor

i have an aja kona lhe pci express card with sdi out. i am getting another dell 24" 1920x1080 monitor for playback of hd. if i go with the kona as an output, i still need the sdi to dvi converter box ($700). is there a real picture quality difference between the sdi converter box solution and just setting the 2nd monitor as a playback (using only dvi) in fcp?

You'll still want the converter. Reason is, that the monitor is a progressive scan only display, so you need the converter to see the images without a lot of tearing in the picture. I really think you'd be better off buying the real deal here. Panasonic has a 17" wide screen HD flat panel that can be had for about 2800 bucks... no need then for the converter, and you gain a true external video monitor which can actually be setup to show you the true color of your material. The dell won't do this at all because you can't set it up properly without a blue only button which I'm quite sure it doesn't have.

MSAI FX 5600 VTDR DVI out & LCD monitor problem

I'm having problems with the card if I connect my TFT monitor using the DVI out on the graphic card. The problem usually occurs when resuming from standby mode or durring the initial startup of the system.All over the screen i see moving golden dots . This stops when I change resolution. If i connect the monitor using the VGA out everything is fine. I've tried the monitor on different card (gigabyte Ati Radeon 8500 Dvi out) and everything was OK. I've checked the cables and tried different driver.
Is there any sollution for my problem, and second can this do a damage to my monitor.

Macbook DVI out?

ok so I just bought a new dell 20" 1650x1080 display as a secondary display for my macbook, replacing my old 17" crt. I was using the mini dvi out to VGA plug which I am also using right now on the new dell display. but my dell monitor also has DVI in, so is there a mini dvi to DVI cable I can get? and is it a big difference? Thanks!

I too use a Dell 20" LCD as a monitor for my MB. I have used both the DVI and VGA adapters and the picture is a bit clearer with DVI, but probably not enough to notice if I wasn't looking for it.

DV playback quality DVI out to TV vs. DVD to TV

I've exported from Final Cut Express, using Quictime Movie, unchecking the make self contained box a 1:15 min. movie.
As I've played back that movie from quicktime 7 Pro and Quicktime X, no surprise, the DV movie does not look so good on my MB Pro screen, or on my attached monitor. But, when I connect DVI out to HDMI in on a vizio HDTV the quality is only so so. I have not deinterlaced in any steps in my process.
I then went ahead and burned the movie with iDVD. The DVD playing to the same TV from the connected DVD player looks terrific.
What am I missing to have best quality Quicktime movie file for playback on a TV from a connected media server?
Quicktime Movie specs:
CODEC: DV
File Format Mpeg 4
Stream Bit Rate 29.6Mbps
NTSC, 720 x 480 29.97 fps
A Ratio 4:3
Interlaced
Colorimetry 4:1:1
Thanks.

This actually makes since to me. If you're trying to play a movie that is 480 wide on a 1080 screen then you are blowing it up over 2x so the quality will suffer greatly. The reason it looks better from a DVD is most DVD players uprez, or upsample the video playback. SD directly from your computer to an HDTV likely won't look as good. You might try playing it through a device like a cable box or sat tuner that allows uprez.
However, here's the positive side, you can play back HD 1080 movies directly through your HDMI cable without the need for a Blueray player and get stunning quality HD. In short, use a DVD player for SD movies, and the DVI>HDMI cable for HD stuff.
