DVI, HDMI or DisplayPort

Hello,
I'm a Windows user but getting a rMBP 15". I was wondering which would be the best way to hookup an external monitor to the MacBook?
I have a high-end 27" monitor with 2560x1440 resolution (LG 27EA83) that has dual-link DVI, HDMI, and DisplayPort connectors. Since I can get a Thunderbolt DVI connector for the rMBP, but the laptop also has HDMI and DisplayPort connectors as well, which one of these would suited the best to connect the monitor to the rMBP?
Since I have no speakers, at this point I'm only focusing on display quality and don't care for audio.
Thanks.
PS: In case if I were also concerned about audio, would you recommend HDMI or DisplayPort?

Conveniently, I did order a DVD-D cable by sheer luck. I just picked the first one that had male connectors at both ends.
Now that I've got that in place, I seem to only be able to get a max resolution of 19290 x 1080 according to the options I see in the Display control panel. I've got the DVI-D cable out from the monitor and into a DVI to mini-display port adapter that connects to a Thunderbolt port on the rMPB.
I think the display is now a little sharper than when I was using the HDMI connector, but that could just be my imagination.
Time to start Googling this to see if I can sort out higher resolutions.
I had no idea there was so much variation in cable type when it came to this stuff.
Thanks for your help!
UPDATED: I finally did what should have in the first place and looked up the specs on the monitor I purchased. 1920 x 1080 is the highest resolution the monitor offers. I can live with that. It's still nearly 2x as large as my rMPB's 15" screen. [http://www.lg.com/us/monitors/lg-27EA33V-led-monitor]

Mini Displayport - DVI - HDMI 5V?

I kind of have an odd setup desire for an external display. I want to send video and audio to my entertainment unit from my MBP across the room. I already have audio sorted out (mini optical -> 30ft optical cable), but the video is a bit more difficult.
What I would like to do is have the Mini Displayport from my MBP go into my Mini DP -> DVI adapter (http://bit.ly/do7McJ). From there, a DVI to HDMI cable would take me to a HDMI over CAT5e/6 wall plate (http://bit.ly/C0bJg). This extender would then go to the TV.
The problem here is that the HDMI over Cat5e/6 extender needs the HDMI's 5V power source. Now, I have followed the pins all the way from HDMI (http://bit.ly/P2wWx - Pin 18) to DVI (http://bit.ly/TNJv5 - Pin 14?) to Mini Displayport (http://bit.ly/BCpof - Possibly pin 20)
Now I guess my real question is does anyone know if this will pass through 5V power: Mini DP -> DVI -> HDMI?
Thanx in advance.
EDIT: My other option would be this (http://amzn.to/gV9PKH), however it is much more expensive and the single Cat5e/6 cable would probably reduce quality.

@Lambstechie - Now that I read into it, if the signal is converted, it can pass over 1 cat6 cable. What I was referring to is a cheaper converter, where an HDMI channel is connected straight to a Cat5/6 channel. And since HDMI 1.3 can work 100% perfect on 16 channels (just no ethernet, audio return, etc.) it seems like 16 channels over two 8-channel Cat5e/6 cables seems fit.
Also, I did not specify this earlier, but the total HDMI (not Cat5e/6) running distance will be under 10 feet, probably around 6 feet. Now when you say the loss of signal strength will happen around 15 ft of HDMI, does that include the distance running Cat5e/6 (approx. 30 ft), or just the HDMI length (6 ft).
@Eww - I see where you are coming from, and I did not see the price of those cables until now. That seems like a great deal. Thank you.

HDMI doesn't work, but MDP- DVI- HDMI works

Hello!
I just got my new Mac Mini and tried to connect it to my TV (a Samsung LE22S8) over HDMI, but this doesn't work since the TV reports "unsupported resolution" (it's the TV's native resolution of 1680x1050, where I also checked all frequencies using an external program and they are as written in the manual of the TV).
However when I connect the TV over a Mini Display Port to DVI adapter, and then use a DVI to HDMI adapter (so that the TV is still using the HDMI input) it works fine.
So what's the difference between MDP->DVI->HDMI and HDMI->HDMI (all resolution and pixel frequency settings are identical)? What can I do to get the HDMI->HDMI solution working?

It also appears that there is no conversion when HDMI-video is extracted from DVI, only that the pins are shuffled.
If direct DVI works on that port, then HDMI-video with an adapter should work as well. As I mentioned above, VGA is present on DVI-I ports on a separate set of pins, and VGA working or VGA not working has no bearing on your problem.
If a Mini DisplayPort is involved, the most common issue is that the Mini DisplayPort connector is not inserted firmly enough. It has a lot of pins and you have to press hard to seat it.
Other possibilities are that the resolution you selected is beyond the capability of the display device, or that the adapter is bad.
Is this the stock display card, or one you added later, and what model?

Have a 2008 iMac 24". How to convert from mini-DVI to mini-displayport?

I bought this awesome device recently:
http://www.monoprice.com/products/product.asp?cid=104&cp_id=10428&cs_id=1042802&pid=6331&seq=1&format=2
It takes the TOSLINK audio output and the minidisplayport output and combines it into HDMI to use in a home theater. However, I just found out that older iMacs (2008) have mini-DVI out, NOT mini-displayport. I've searched high and low and I cannot find a cable/adapter combination that will convert this for me so I can use it on my 2008 iMac. Any suggestions?
IDEALLY it would be a male mini-dvi to female mini-displayport. This doesn't seem to exist.

Well, there is this one
http://www.atlona.com/Atlona-DVI-to-Mini-DisplayPort-Converter-p-17859.html
but it is expensive. Going from DVI to DisplayPort is not simply a matter of changing the shape of the connector. And you would need a Mini-DVI to DVI adapter to connect to this device.

Differences between adapters? (MiniDVI- VGA/HDMI and DisplayPort- VGA/HDMI)

Hello everyone
I'm going to buy a new Late 2009 Mac mini, wich for the time being will be connected to my old 17 inches Samsung LCD using VGA (I know, it's not the best solution but I can't afford buying a new monitor now) and occasionally to my Samsung FullHD LCD TV. So here are my two questions
1) What's the difference between using a Mini-DVI to VGA adapter and a Mini-DisplayPort to VGA adapter?
2) What's the difference between using a Mini-DVI to HDMI adapter and a Mini-DisplayPort to HDMI adapter? Are both HDCP compliant?
I know these may be stupid questions, but I'm a ex Windows user and the "Macverse" is new to me Thanks

One important difference between the VGA versions of the adapter is that DisplayPort does not output analog video. As such, the adapter is expensive because it has a D to A (digital to analog) converter built inside of it. It may be more prone to trouble, but it is also able to be firmware upgraded, which has already happened one time. Anyway, I would tend to choose the DVI version of the VGA adapter if for no other reason than it being cheaper.
The difference between the DVI/HDMI adapters is not so big I think, so it wouldn't matter which was used to drive an HDMI display. Either port on the back of the mini will support HDCP, and that is important with HDMI.

HP LP2275w Monitor HDMI to DisplayPort possible?

Hello forum,
In the proccess of connecting my monitor HP LP2275w to computer HP Pavillion. The computer has HDMI and VGA output, the monitor has DVI and DisplayPort inputs. Recently bought a HDMI to DisplayPort adapter, in order to use the HDMI-cord, but it does not work. My computer does not "find"the monitor what so ever.
Why does the adapter not work? Do I need som sort of drive-updates?
Hopefully the forum has all the answers.
/HP owner

Hi,
In theory they are BOTH using digital signals therefore just straight one to one BUT practicality, this is a hit and miss business in many cases. Back to your connection: have you tried to use F4 key which tells the machine to send signals to the monitor ?

2008 MBP -- DVI out -- DVI/HDMI converter -- HDTV ?

Hi guys,
I'm gonna go ahead and apologize in advance if this has been asked before, I'm having a bit of an emergency.
The backlight on my 2008 MBP (model A1260) has gone out -- I can still somewhat see the screen but it's extremely dim. I'm wondering if I can buy a DVI/HDMI converter and run the video out to my HDTV. Are there any extra supplies I'll need?
Also, any instructions for enabling the HDTV as my external display would be greatly appreciated as I'm barely able to read anything on the screen in its current state.
Thanks so much!

HP Elite L2201X HDMI to Displayport

Hi,Operating Systen - Windows 7 64bitI have a Lenovo Y460p laptop. It has a HDMI out on the video card. I also have an HP Elite L2201x with a DisplayPort in. I bought a Startech.com HDMI2DP which is supposed to actively convert the HDMI to DisplayPort. When I plug up both to the converter, the monitor just blinks orange. The monitor has been installed using the CD. The converter has been hooked up correctly. I don't know what the problem is. Can anothing help?

gsuren, Here are the specs for your HP Elite L2201x 21.5-inch LED Backlit LCD Monitor. According to the specs, your HP L2201x monitor has a single DisplayPort input and no other video connections. You must connect the monitor to a computer with native DisplayPort output or use an "ACTIVE HDMI-to-DisplayPort CONVERTER". From "HP ZR24W and Displayport"11-05-2012 06:53 PM - edited 11-06-2012 07:46 AM @ off1c3r, mikasa, bcody79, and others with the same DVI-D or HDMI to DisplayPort issue. The problem isn't with the monitor... it is with the way you are trying to connect your computer to the monitor. The monitor has a DVI-D input and a DisplayPort input. If your computer doesn't have native DisplayPort output, you can't use the monitor's DisplayPort input without an expensive active converter. But you say you purchased a DVI-D or HDMI to DisplayPort adapter cable??? Wrong, unless it is an active converter there is no way to go from DVI-D or HDMI at your computer to a DisplayPort monitor. The cables you have purchased are designed to go from a computer's DisplayPort output to a monitor's DVI-D or HDMI input. This is facilitated by the graphics adapter sensing an active DVI-D or HDMI connection (via adapter cable) on the DisplayPort output and switching the signaling to DVI-D or HDMI. Please read DisplayPort.org/FAQs for more information on the subject. You can also check out wiki/DisplayPort for more information as well. From DisplayPort.org; Q: I just purchased a monitor that only has a DisplayPort connection. How can I hook this up to my computer that only has VGA, DVI or HDMI?A: There is not a cost effective way to do this. The adaptors that are available only work from a DP computer to a VGA, DVI or HDMI monitor and not the other way around. If you have a desktop you can purchase a graphics card with DisplayPort. Our best advice: Before you purchase a DP only monitor make sure you have DP on your computer.

Cinema 30" PC Monitor can use w/HDMI or DisplayPort?

Hello,
I have a 5 years old 30" Cinema Display I use as PC monitor. I want to upgrade my motherboard, and the ones I am interested in do not have DVI ports anymore, only HDMI and DisplayPort. Is it possible to adapt my display DVI cable to either of these ports and still retain 2560x1600 resolution? What do I need to do?
thanks

Macbook Pro 2011 DVI HDMI out does not work with TV when the power cable is connected

My Macbook Pro (Early 2011) DVI HDMI out does not work with TV when the power cable is connected. If get the blue screen and then can use the macbook but nothing is displayed on the TV. If i go into display I can see that there are two screens but nothing displayed on the TV. If i take the power cable out at this point the TV shows the second desktop as expected. If i then reconnect the cable, the screen flickers, as though it is being affected by the power cable, and the screen goes blank on the TV. Only if i remove the DVI cable do i get the blue screen again. If i remove the power cable and reconnect it will do it every single time, so i cannot see it being a TV issue or a minor glitch.
I have had this working previously but at the minute it seems to not be playing ball....any thoughts
Thanks
Dan

Any ideas?

I've just hooked my 20" iMac up to my Toshiba 37" HDTV using a mini dvi-HDMI adapter, and works well, EXCEPT for the green tinge (or hue) that is showing up on my TV. Any suggestions or ideas?

I've just hooked my 20" iMac display up to my Toshiba 37" HDTV using a mini dvi-HDMI adapter, and everything works well, EXCEPT for the green tinge (or hue) that is showing up. Everything else looks pretty good though..... The color that is on my iMac is still good, Its just green on the TV.
Anyone have suggestions or ideas?

Try opening the Display System Preferences, then click on the Color options in the Display preferences window that appeared on the Toshiba display. Click on the Calibrate button and follow the instructions for creating a custom ColorSync profile that will hopefully solve the green tinge issue. The Apple Display Calibrator Assistant software that launches when you click on the calibrate button will walk you through the process.Assuming that the green tinge is minor and that you don't have a more serious cable or hardware issue, I am hopeful the results will be worth it.

Mac Mini + DVI- HDMI + Toshiba 42RV530U = black screen

Hi all, I have a new Intel Mac Mini 2GHz and a Toshiba 42RV530U REGZA HDTV that I'm trying to connect, with only a black screen so far.
I believe the DVI output on the Mini is working - I can at least get a picture with a DVI-S-Video cable, but it's obviously lower resolution. The DVI-HDMI cable works - I tried it on our cable box.
When the DVI-HDMI cable is hooked up to the HDMI-1 input on the TV, the "No Signal" warning vanishes, but it's replaced by a black screen. No amount of fiddling with SwitchResX has worked so far.
I've tried coming up with values for SwitchResX based on these numbers from the manual (don't know why the H Freq and V Freq give 2 values for each). I couldn't get exact values, but pretty close. I'd ideally like to get 1080p working.
Name Resolution Vert Freq Horizontal Freq Pixel Clock
480i 720 × 480i 59.940/60Hz 15.734/15.750kHz 27.000/27.027MHz
480p 720 × 480p 59.940/60Hz 31.469/31.500kHz 27.000/27.027MHz
720p 1280 × 720p 59.940/60Hz 44.955/45.000kHz 74.176/74.250MHz
1080i 1920 × 1080i 59.940/60Hz 33.716/33.750kHz 74.176/74.250MHz
1080p 1920 × 1080p 23.976/24Hz 26.973/27.000kHz 74.176/74.250MHz
1080p 1920 × 1080p 59.940/60Hz 67.433/67.500kHz 148.352/148.500MHz
I've also tried repairing permissions, rebooting many times, deleting the windowserver.plist files, zapping the PRAM, etc. SwitchResX identifies the TV as "TSB-TV", which sounds the same as other posts with different Toshiba TVs. I'm able to remote into the Mini via Remote Desktop Connection to play with settings, etc.
Any suggestions? Would a DVI to Component cable work? The TV does have an analog RGB in, but this won't support high def. Thanks for any help!
-Frank

An unforeseen twist... I tried hooking up the Mac Mini to a DVI computer monitor, also with no picture. When I hook up my Powerbook to the Toshiba via the DVI->HDMI cable.... Picture! So, looks like my new (refurbed) Mac Mini has a bad digital video output. Seems a little strange though, since the analog video output on it is working fine.
Off to the Mac store tomorrow.

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.

Connecting MacBook to Sony Bravia via DVI-HDMI!

Hi I am having major issues with my Macbook connecting to my Sony Bravia KDL-32V4000 I now have 2 different DVI-HDMI leads as well as the Apple Mini-DVI-DVI and still have absolutely no luck.
The Macbook is picking up the Television absolutely no bother at all but there is just nothing at all coming up on the Television its self it doesn't even recognise that I have the computer in the HDMI slot nothing at all just blank!
Any help would be greatly appreciated as it will save me buying more and more cables if this fails to work will have to go with the DVI-VGA I guess would rather fix this though!
Thanks!

I bought a mini-DVI to HDMI and an HDMI to HDMI cable. Once I went into settings for the display, I found that the TV was acting as a second monitor and that it was off to the right of the macbooks own screen. Thus if i moved the mouse to the right it could control the second monitor. You are able to move the screens so that they have the same data on each or use them as two screen with different info on each. Each screen is clearly visible in Spaces and it works a treat.
It is also possible to use the TV as the only screen. The way to do this is to connect up and close the lid on the mac. Once the light on the front starts blinking you can wake it up by using your mighty mouse or external keyboard. once awake, assuming you have chosen the correct HDMI connection from the TV the TV will act as the only monitor at full resolution.
The problem I have, is that I have not been able to get the sound to work. I have used the earphone socket and connected that to external speakers as I cannot seem to get the analogue signal on the TV on anything but an AV channel (not an HDMI channel). Thus the sound works on one channel and the image on another. My TV is a Sony KDL40w5710 - thus if anyone know the solution to getting the sound running through an HDMI channel on my TV it would be appreciated if you could contribute.
Cheers
