Diminished resolution using DVI Adapter

Had to buy a Mini DisplayPort to DVI Adapter for my new MacBook Pro. My previous MacBook Pro had a DVI port. As soon as I started using the Apple Cinema Display (Aluminum version), I can see the the resolution is lower/diminished. Why should this be?
The resolution it is set at now is: 1680x1050. Any thoughts? Thanks.

Is it a 30" display? That needs the Mini DisplayPort to Dual-Link DVI Adapter

Mirroring must be off ("Arrangement" tab of "Displays" system preference) to use external displays at resolutions higher than the laptop's display.

Maximum resolution using DVI adaptor?

I have a Macbook pro that has 1 nvidia geforce 9400M and 1 geforce 9600M GT (it's the last mac book pro before the current one offered online) and I would like to know if my 30" HP Monitor LP3065 will work at its native resolution which is 2560x1600 using the mini to DVI adapter. Thanks!

A dual link adapter is required for any resolution larger than 1920 x 1200.

What is the maximum resolution available for use with the Apple Mini DisplayPort to Dual-Link DVI adapter?

Hey guys,
I found out an answer by myself...
The missing link : the MacBook Pro needs to be powered... as in you need to plug the charger in...
In conclusion, you simply plug everything, turn on the MacBook Pro, close the lid, and there you go !

Will my Airbook (11" late 2010) w/ NVIDIA GeFORCE 320M 256MB using the Mini Display Port to Dual-Link DVI Adapter support the Dell 3007WFHC (30") monitor at full resolution (2560X1600)

Works fine at 1280X800 (with out without MDP DL DVI Adapter) - cannot get any higher resolution

Hi ddickson01,
The MacBook Air 11 inch late-2010 model does support 2560 x 1600 resolution on an external display. See this specifications article for reference -

Thanks for using Apple Support Communities.

HDMI to DVI adapter not allowing full resolution when using Mac OS but does with Windows 8.1

I have a Mac Mini and using the HDMI to DVI cable that came with the computer the maximum resolution it will allow is 1280 x 1024. I have 2 of the same monitors. The other is connected with DisplayPort to VGA adapater and displays full resolution (1920 x 1080) on both monitors but the HDMI to DIV will only show 1280 x 1024. I thought maybe it was my DVI cable or the adapter but when I boot up in Windows 8.1 through bootcamp both monitors display at full 1920 x 1080 resolution. Why does Windows give me the option for full resolution on both but the Mac OS doesn't? All the latest updates have been installed. I've contacted support and all the things they had me do didnt work. I see all these posts with people complaining about the same resolution issues. Is it that difficult for this to work?

Humm... the dual Samsung 21.5" monitor setup on my 2010 Mac Mini running Mavericks works a expected.One is on the HDMI to DVI adapter and the other in on a Kanex Mini DisplayPort to DVI adapter.
Try > Display Menu from the Mac App Store and see if you can select 1920 x 1080 for both monitors using it.
Addtitionally, are you sure that it the HDMI to DVI monitor that is not getting the correct resolution...? Most people are complaining that it is a VGA connected monitor that is not getting the correct resolution.
If it turns out to be VGA connected monitor, then try using a Mini DisplayPort to DVI adapter and DVI cable for that monitor instead of VGA.

Trouble with 30" HD Cinema Display using Mini DisplayPort to DVI Adapter

I bought a new MacBook Pro and I am having trouble getting the full resolution to work with my 30" HD Cinema Display (purchased in 2007 max resolution 2560 x 1600) using a Mini DisplayPort to DVI Adapter.
According to the specs page, http://support.apple.com/kb/SP581 , the max resolution of the HD external display is supported. Unfortunately the max that I can set it to is: 1280 x 800
Has anyone else had the same issue?
If this isn't resolved I'm likely going to exchange my MacBook Pro for one that can support this display.

So I went and bought the Mini DisplayPort To Dual-Link DVI Adapter as suggested and it seems to work great.
Now the problem that I have is when I open up Apple's DVD player, the screen is blank but I can still hear audio.
If I unplug the display, the movie will display properly. Rebooting with the display plugged in doesn't help either. I also deleted all the DVD players enc setting files so that they would re-initialize but no luck.
Any idea what this problem might be??

Static using HDMI to DVI adapter on 2011 mini

Hi,
I bought my first Mac last week, the i5 2.3ghz mini. I originally set it up on my TV (using HDMI), downloaded/installed the updates, and messed around a bit before deciding that a 42 inch display isn't as convenient as I thought it would be.
Using the HDMI to DVI adapter that came with the mini I hooked it up to my 19 inch acer monitor. While booting can see the boot screen, but the display is very staticy. Once it logged in I was able to barely see well enough past the static to mess around with the display settings thinking that maybe the mini was trying to push an unsupported resolution to my monitor (because I set it up on my TV at 1080p).
I read up on the issue and it seems that some have had problems with static while waking up from sleep. Mine has static all the time.
By a stroke of luck I happened to have a HDMI to DVI cable on hand. I tried it out and it displayed beautifully. No static, works as I expected.
So the problem seems to be the adapter that came with the mini, the DVI cable that I was originally using (the cable works with my PC), or the HDMI port on the mini itself not working well with Apple's own adapter (not likely).
I was just wondering if anybody else has had this issue, and if they fixed it did it end up being the adapter or did replacing the DVI cable with a higher quality cable do the trick.
Thanks,
Corey

I just posted a similar issue here. The weird thing is that on my system, a Dell monitor works with the HDMI-DVI adapter but the Acer monitor doesn't. Do you think getting another adapter would resolve it fo rme? What kind worked for you?

Using DVI to Video/ S-video Adapter

I have been trying to use my DVI to Video/S-video adapter with my Daewoo Flat Screen (not flat panal) TV. I have tried every resolution and still everything is small and Fuzzy and it is extremely hard to make out anything. Im wanting to use that adapter to play my game. I am connecting using a S-Video Cable. Please any help. It is a regular Television set NOT LCD or Plasma or any kinda of flat panal just has a flat screen.
Thanks.
SaL

Not necessarily. It will depend on what eventually solves the problem. I think you still have a couple of choices to try:
1. Download (& purchase) a copy of DisplayConfigX. This utility will allow you to "manually" set resolutions that your mini can provide, basically "overridding" what the mini thinks is connected to it. (ref: http://www.3dexpress.de/)
2. Replace the DVI-to-S-Video adapter to rule out the adapter being the problem. (You may want to try this first.)

Resolution problem with Mini DisplayPort to DVI Adapter

Hi,
I have a unibody MBP 15', running on 10.5.8. I use 'Mini DisplayPort to DVI Adapter' (http://store.apple.com/us/product/MB570Z/A?fnode=MTY1NDA5OQ&mco=Nzk2MDk5OQ) to connect to my external HP LP3065 30' monitor. I get max resolution of 1280 x 800 for external monitor which supports resolution of 2560 by 1600.
This monitor used to work fine with old MBPs, but not with my unibody MBP. What could be the problem? Adapter or MBP?
I am missing high resolutions
Thanks in advance!
Rohit

You have the wrong adapter. The one you have is single-link DVI, which does not support 30" displays. You need the Mini DisplayPort to Dual-Link DVI Adapter:

Why no use a DualLink DVI Cable with the MiniDP-DVI adapter to power 30"?

I'm a bit confused here...
looking at my Mini-DisplayPort to DVI adapter, the pinout appears to be a Dual Link DVI port. Is this true?
Can someone explain to me why I can't just buy a Dual Link DVI Cable now and use this to power my 30" monitor at its native resolution?
I would have thought this was gone over many times already - but I have been unable to find it.
Am I missing something?

A Mini DisplayPort to single-link DVI adapter just has to connect pins between to two connectors. The computer detects the adapter, and send DVI signals over the Mini DisplayPort connector that end up on the correct DVI pins. Unlike DisplayPort, DVI uses separate data and clock video signals, and there are not enough DisplayPort signals to handle clock and video for dual-link. The Mini DisplayPort to dual-link DVI adapter contains circuitry to separate video and clock signals from self-clocked DisplayPort signals, so can drive all the required pins on a dual-link DVI port. This circuitry gets power from a USB cable that plugs into the computer. This makes it more complicated and more expensive than the single-link version.

T520 and WQXGA (2650x1600) resolution with Active DisplayPort- DL-DVI adapter

Howdy,
I'm seeing a lot of posts saying I can connect a T520 to a WQXGA monitor using an Active DisplayPort->DL-DVI adapter.
I've got a BizLink brand one which has been confirmed working. But when I use this with my T520 the maximum resolution it offers me is 2048x1536 (this is 4:3) resolution.
Is there something I need to do to get access the WQXGA resolution? I tried creating a 2560x1600 resolution but it just comes up with an error message saying it is not supported.

Well I just set my display to discrete (instead of optimus) and after some fiddling around I was able to get it working - both via displayport and my displayport->dl-dvi adapter.
I also tried to set it to integrated, but was unable to get it working. So I guess the intel video (or more likely drivers?) are the weak link here.
It's a little disappointing as I was hoping to still use optimus tech - although I haven't bothered to fully explore the settings (I am not familiar with the technology, I assume thre is no way to switch between integrated/discrete/optimus at runtime?) it wouldn't surprise me if this was not possible.
As an interesting aside I also had to physically power off the monitors I was playing with. As in, if I had connected to the monitor with my laptop in optimus mode, it would only offer me 2048x1536. After switching my laptop to discrete and booting back into windows, it would sitll only offer 2048x1536, even after plugging/unplugging the cable. I had to turn off the monitor (and additionally reboot laptop again, although not sure if this made a difference) before I could get QWXGA working.
It may be worth updating the knowledgebase article to include this information.

How do i connect my mac mini to a kvm switch using the hdmi to dvi adapter?

I want to connect my Mac Mini using the HDMI to DVI adapter to a KVM switch cable. I have an Iogear KVM switch. The cable from the KVM switch has a male VGA end connection. I have been trying to determine the right adapter to connect the female DVI connection to the male VGA connector. I will be using the Mac mini and a PC running through the KVM switch. This is doable as the iogear switch is compatible with both a PC and a Mac. Any ideas out there? Thank you.

You would need to get HDMI or DVI to VGA CONVERTER, not a simple adopter. The converter requires USP connection for power. HDMI is only digital while VGA is analogue.

If your MIni has a mini displayport or Thunderbolt port yu can get a les expensive mini displayport to VGA afopter.

Having problems connecting a late 2011 Macbook Pro 2.2ghz i7 to a Sony KDL-32L5000 using a display miniport to DVI adapter (DVI to VGA cord). The TV is not detecting the macbook. Anyone have this problem?

You really have to mess with the resoluton, espescially the refresh rate, as it varies from projector to projector, monitor to monitor. Even within the same brand! Because so many manufacturers are trying so many different things to become the next cool kid on the block, and the way the formats are being configured that's now part of the game.
That's why so many professionally produced corporate shows hire a dedicated projectionist for the video presentations. Too many bugs in the honey.
Refresh & sesolution are the first things to look at.
Just so you know that colors in PowerPoint PC, and PowerPoint Mac, don't exactly match... go figure.
I forgot to mention another thing, sometimes it's the projector that needs to be tweaked.

New iMAC to Dell 3008 using Mini DisplayPort to Dual-Link DVI Adapter

I just brought the new iMAC 27" iCore7. Previously I was using old MBP with dual link DVI to DELL 3008 and they did fine.
But Today I connect the Dell 3008 to my new iMAC using Mini DisplayPort to Dual-Link DVI Adapter...They could not work properly...
The dell shows images in red with flickers....
I've contacted the phone for help...and they said nothing could be done????!!!!!
Anyone could help??
THX

just update my progress...
I had made calls to Apple technical support center in HONG KONG for help...
To my surprise...they even did not understand what I was saying(Or just pretending...)....One interesting guy said I could take the new iMAC back to service center to change the 4850 display card to older version...or call DELL for help!!!!!
Fuxking Apple technical support center in HONG KONG
I was almost hopeless until I found a minidisplay port to display port cable in Circuit Assembly:
http://estore.circuitassembly.com/products/Mini-Displayport-to-Displayport-Adapt er-Cable.html
ONLY $14.95 !!
They sent the cable to me in 3 days time...and I hooked it up right away when I received it today...my Dell 3008 could display 2560 x 1600 normally again!!!!!
The problem is: Apple is still selling its FUNCTIONLESS Mini DisplayPort to Dual-Link DVI Adapter at high costing....sounds like cheating others....
What' s wrong with the Apple nowadays???

Black & white screen using DVI-to-Video adapter

I've got a strange problem. I'm connecting my MacBook Pro to a Sony TV using Apple's DVI to Video adapter and a composite video cable.
As soon as I make the connection, I see the Mac's screen appearing on my TV, but it is in black & white! And it flickers a little every few seconds. The only way to get to a colour screen seems to be to re-boot the MacBook. It's quite annoying.
Previously, I've always had a colour picture come up immediately. The problem started to crop up right around the time I installed Snow Leopard, in fact, although I'm not sure whether it's a coincidence or not. And I don't think it's related to my TV. Any thoughts?

same problem here... first time i plug it in after a reboot it's in color. when you disconnect it and try again later it'll be in black and white and there's nothing you can do to fix the problem. only choice you have is to reboot your computer. as you can imagine, having to reboot the computer every time you want to use the adapter is REALLY annoying
