HDMI to DVI No Signal Detected

I have a late 2006 MacBook Pro running OS X 10.6.6. I recently purchased an LG LED-LCD television as well as a HDMI to DVI adaptor cable, both from Amazon (the cable is an Amazon Basics cable). When plugged in to both the laptop and the television, there is no signal detected by the television and no display detected by the laptop. I've tried each of the three HDMI ports on the television, but to no avail. I returned the cable and exchanged it for an identical one, but the problem persists.
In searching through the forums, I've seen that quite a few people have had issues with this same setup, and I'm wondering if somehow I need more than just the cable to connect to my television (which doesn't make sense, but could still be the case). I've run a diagnostic on my laptop during startup, and found no issues with the hardware, so I'm 99% positive that I don't have a bum DVI port. At this point I'm just not sure what to do to get this to work, so any assistance would be wonderful.

Sorry for any confusion, my last post was sent before reading your second post.
The VGA test proves nothing about the DVI output. The DVI ports on these Macbook Pros is a combo DVI and analog VGA port (DVI-A). The DVI-VGA adapter does nothing more than connect the VGA to VGA, and does not convert the DVI to VGA. You have to use an actual DVI device to test the DVI. The 4 pins and large blade on the end of the DVI connector are the VGA pins - they can be omitted on a DVI-HDMI adapter with no harm.
I really don't know if there could be a problem with the software on the Mac and/or TV, and the cable just fine.
Perhaps try to seek out someone who has a working DVI-HDMI cable to try? Or try a store that will demonstrate that it works and has a money back guarantee?

Lenovo K1 1304 Tablet - Micro HDMI to DVI No Signal

Hi,
I'm having a problem here. I want to connect my Lenovo K1 tablet to a TV or monitor with DVI input using HDMI cable and HDMI to DVI Adapter. This should work perfectly fine since both hdmi and dvi are backwards compatible with each other and I've succesfully connected a different tablet like that before, yet I get no signal when trying to output a video from Lenovo K1 Tablet.
Micro HDMI output port on my K1 works fine since I can output signal to HDMI input on my TV but not to DVI input using HDMI to DVD Adapter and like I said this should work just fine.
Any ideas anyone?
Thanks.

It doubt the adapter has to be HDCP "compliant", because it should just provide a mapping of pins/wires from HDMI to DVI, so any handshaking would occur between the endpoints (tablet and display device). In case it helps, here's the pin mapping:
http://pinouts.ru/VideoCables/hdmi_dvi_cable_pinout.shtml
There are some different flavors of DVI, such as DVI-D versus DVI-I, with single or dual links - is it possible that there is a mismatch between adapter, cable, and device?

No signal apple tv3 to projector via hdmi to Dvi-d

I have a 3rd gen Apple TV. Works great on my 1080p tv, with optical out to my surround amp. When I connect to my Panasonic pt-ae500 720p projector via hdmi to dvi-d I get no signal at all. The projector is HDCP compliant and I can connect my ps3 to it at 720p no problem.
I have tried changing the edid settings on the projector, and changing resolutions on atv.
Any suggestions? I really need to set up my home cinema incorporating ATV
Thanks
Steve

It's an inherent problem between the ATV 2 & 3 and certain older models of TV / Projectors. Something to do with negotiating the signal between the two devices, the ATV falls over.
I also have this issue. I dug out my old PT-AE500 only to find that my ATV 2 was getting stuck on the Apple logo. No solution yet though, unfortunately.
There is another (old) thread on it here: https://discussions.apple.com/thread/2631562?start=0&tstart=0
There are a couple of ideas there, one of which was to switch the ATV on *before* plugging in the HDMI cable, let it boot up (give it 2 mins or so) then plug in the cable. This solved it for one person on that thread, but I can't get it to work here! I'll give it another try.
It's only the Apple Tv that has this issue as well. My MBP, Mac mini, etc, work perfectly. Just inconvenient having to lug them to the projector each time we want to watch a movie
Sorry I can't be of much help, but maybe have a read through that thread to see if any of the tips there work for you.
I'll also report back if I manage to find something that DOES work!

HDMI to DVI Problems (Detailed in Post)

I have two brand new Core i5 Mac Minis running Snow Leopard. They shipped with the usual HDMI to DVI adapter, to which I plugged in an HP S2031 displays; however, OS X is detecting each display as two separate displays. In addition, if the computer goes to sleep at any point, the HDMI port will stop working alltogether until the computer is restarted.
I tested it with an Asus 19" display and a Dell 20", and the same thing occurs, so it's not display-specific.
Any thoughts, comments, or suggestions?

I just installed the 10.6.8 combo update to be sure I have the latest drivers, but no luck. Also zapped PRAM, but that didn't help either.
Monitor remains responsive if only the display goes to sleep, but if the whole computer sleeps, then the HDMI stops sending a signal.

HP x2301 no signal detected?

Okay, so here's my setup. I've got two computers with me; one, a desktop PC I built (nVidia GTX 670 graphics) and two, a macbook pro ''13.
My desktop is set up with dual monitors, both 1080p; one an Asus and the other the problematic x2301. They are connected directly to the GTX 670 with a DVI and HDMI cable respectively. They both worked absolutely fine until this morning.
I dual boot Mac OSX 10.8 and Windows 8 on my desktop, and this morning when I tried my newly installed Windows 8 the x2301 suddenly decided to turn black. The computer still thinks its plugged in though and it recognizes it in the displays preference pane, but the monitor itself is black and says no signal is coming in from the HDMI. When I tried to switch them around, as in HDMI into the Asus and DVI into the HP, the Asus had a fuzzy image and the display settings had changed. When it was set to the native 1080p, the image wasn't perfectly aligned onto the screen and it was dizzying to look at. The HP showed nothing. When I plugged both the HDMI and the DVI cables into the Asus, I could cycle between HDMI and DVI and get both pictures (the only thing was the HDMI picture was fuzzy again).
The only thing that could be wrong I thought was the hardware in the monitor itself. I broke out the Macbook and plugged in a VGA cable into it, and lo and behold a picture was shown on the HP. It was set to 1920*1080 at 60Hz but there was oddly some black space (about a centimeter) at either side of the picture. The image itself was clear though; it didn't seem as if it had been compressed.
By the way, I tried all of these tests on Mac and Windows on the desktop. Neither would recognize the HP. Even when the Asus was disconnected and the HP solely connected by either DVI or HDMI the BIOS wouldn't show onto the HP.
Taking all of this into account, it means that:
1. The graphics card is fine, as an image was displayed on the Asus and just not on the HP,
2. Both the HDMI and DVI cables are fine, as they can both be connected to the Asus.
3. The HP doesn't seem to be totally broken, as the macbook can show a picture on it.
What's up with the monitor? I have no clue what could be wrong because the HP does detect VGA and it was working absolutely fine not five hours ago. The desktop PC is totally fine too — I'm typing this post on it using the Asus monitor. Should I send in the HP to a technician? I tried to reset it to factory settings using its OSD, but no luck.
What about the fact that the HDMI signal is fuzzy on the Asus? That has absolutely nothing to do with the HP — after all, the HP is disconnected!
This is making me tear my hair out!
Apologies for the tortuous post, I will clarify if need be.

Contact HP and arrange to send it in for warranty service.
Best regards,
erico

Does Mac Mini's HDMI-to-DVI cable support analog DVI monitors?

The Apple website shows that the new (late 2012) Mac Mini comes with an HDMI-to-DVI adapter cable in the box :-)
The DVI video connector standard supports both analog and digital video signal modes, but not all models support both modes.
I have an old PC monitor with a DVI connector, which is probably analog only. Will this work with the new (late 2012) Mac Mini?
In other words: does Apple's HDMI-to-DVI adapter cable support all DVI monitors, or only those with a digital input?
Many thanks!
- Martin

Your right about the DVI standard support both analogue and digital. The three types are
DVI-A (analogue only)
DVI-D (digital only)
DVI-I (supports both)
In this case the HDMI to DVI adaptor will only support digital DVI. This is because the HDMI port only supports digital.
Generally monitors with a DVI port support digital DVI, if you compare the socket and pins layout on the monitor to the one on the Mac adaptor if they are the same layout then that should indicate the monitor indeed supports digital DVI.
Note: The maximum resolution supported by the Macs HDMI port is 1920x1200, if your monitor supports a higher resolution then you should get a Mini Displayport to DVI adaptor or if needed a Mini Displayport to Dual Link DVI adaptor (for the highest resolutions).

Mac mini display is flicking via HDMI to DVI adapter and DVI cable

i have received mac mini server (mid 2011) recently. mac mini is connecting the display via HDMI port using DVI cable with a HDMI to DVI adapter.
the display shows constant flicking. white dots/lines show randomly. it is like those signal noise when watching analog TV.
the same display works fine and well with macbook pro (early 2008) via DVI port.
please help. please advise.

So you know the display is working.
It seems to me you have a few possible problems.
1 HDMI-DVI cable is bad
2 DVI-cable is bad
3 Connections between cables or computer or monitor are bad.
4 HDMI port on the computer is bad.
I assume you've tried #3, and re-connected cables and wiggled inputs. So then try replacing 1 and then replacing 2 which are cheaper fixes than replacing/fixing 4.........
FYI, I'm connect my mac mini using the same setup you describe, with no issues....also inspect the cable ends carefully to look for any problems.

HDMI and DVI port not working on 880GMA-E35

Hello,
I want to use the HDMI port of my 880GMA-35, but the monitor is not getting a signal. I know that the board has two jumpers to switch between the DVI and the HDMI port. In the delivery state the jumper is set to HDMI, but I don't get a signal. There is also no signal, if I switch the jumper to the DVI pins. I have tested this setup which different cables (HDMI and DVI) and two different monitors.
After this test I get a guarantee replacement of the board. The new board is also not working with HDMI or DVI. The VGA port of the first board was working as supposed and I don't see any Bios settings to activate the monitor ports.
Are there any suggestions to solve my problem?
Thanks in advance and kindly regards
Daniel

Mac Mini (Mid 2011) display artifacts HDMI to DVI at native res

Hello,
I recently changed monitor configurations and in the process moved my Mac Mini (Mid 2011) to a HP LP2065 monitor. The connection is made through the stock supplised HDMI to DVI adapter.   The monitor and the DVI cable work successfully with other machines.
What occurs is only certain colors, usually black, result in the display being red and/or sparkling and/or static (like TV static) when the monitor is set at its native resolution of 1600x1200.
If I bump the resolution down to 1280x1024, or lower, the black color returns and I see no display glitches.   If I bring the resolution back up to 1600x1200, the display artifacts return.
A few google searches suggest I use a DisplayPort to DVI adapter instead as some monitors are "finicky".   Does anyone agree with that? It seems peculiar to me -- why would a digital signal have analog-looking glitches?
Any ideas welcome.. thanks for reading

Your monitor has a native pixel resolution of 1920x1200. There is no point in trying for 1080-p or -i.
I run two 1920x1200 monitors via HDMI (with passive cable adapters where necessary) and I use these choices:
...and they are both pixel-sharp, filling the screen, and yet menu bars totally visible!

Using DVI to VGA adaptor with HDMI to DVI port on Mac Mini Server

Hi - I couldnt find anything on this, so I decided to post a new topic. We just recently purchased a Mac Mini server at work for iOS development. Before we launch in in one of our data centers and start remoting into the system, we need to conduct basic setup on the system.
For this, we pulled out an old stock VGA montior we have around the office, and found an apple DVI to VGA adaptor (http://i51.tinypic.com/2mzb4lc.jpg)
The problem is, the pins dont exactly line up... on the DVI to VGA adaptor there are 2 extra pins above and below the horzontial pin on the left hand side (http://i52.tinypic.com/2mxhg1j.jpg) that do no exist on the Mac Mini HDMI to DVI adaptor (http://i53.tinypic.com/2ywesrp.jpg).
Ive checked other converters and it seems that all of them are setup the same way, with two pins above and below.
Has anyone else had to deal with this issue? I really dont want to go and buy the Mini DisplayPort to VGA adaptor for one-time use.
Thank you!

Welcome to  Discussions!
What you are seeing is the difference between an analog and digital DVI connector, as DVI as a specification can provide both types of signal, depending on implementation. When used in a mode where only one or the other type of signal is provided, the different connectors prevent a mismatch. VGA being analog, the DVI to VGA adapter is using an analog DVI connector. The other connector you are dealing with is a digital only connector. HDMI is digital only, hence the HDMI to DVI adapter being digital only. Thus you can not adapt from the HDMI port to VGA with just passive adapters, you would need a conversion device between. It would be cheaper and more effective to use a Mini DisplayPort to VGA adapter.

No HDMI or MiniDP-to-VGA output, but HDMI-to-DVI is okay

I purchased my Mac Mini almost a week ago and I've been having strange issues with getting my various monitors to work with it.
I don't own any Thunderbolt or native MiniDisplayPort monitors, however I do have a number of VGA monitors, as well as some HP LP2475w monitors which have VGA, DVI (DVI-D and DVI-A), HDMI, and DisplayPort inputs.
When I have OS X installed on my Mac Mini, the Apple MiniDP-to-VGA adapter works with my VGA monitors, but only when OS X has loaded. My monitors all say "no signal" during the boot-up phase. However I had no problems when I connect my LP2475w monitors to the Mac Mini via the HDMI-to-DVI adapter: I see the grey screen during bootup, can see/access the boot menu, and everything works fine.
Today I purchased a HDMI cable to connect the Mac Mini to my LP2475w monitors to see if that would work. Well, it does work... almost, sometimes, but not most of the time.
When I use a direct HDMI connection my LP2475w says there's no signal, unless I plug the cable in during the text-mode portion of Windows' bootloader (under Boot Camp). As soon as Windows loads, or during the grey-screen bootup section my monitors all say there's no signal. There is nothing wrong with the cable or my monitors.
Here's a table:
Connection
Can see boot screen/boot menu
Can see OS X (when loaded)
Can see Windows (when loaded)
HDMI from Mac Mini to LP2475w
No
Not tested
No
HDMI-to-DVI from Mac Mini to LP2475w
Yes
Yes
Yes
MiniDP-to-VGA from Mac Mini to VGA monitor
No
Yes
No
So what's going on here then?
Has anyone else had the same problems as me?

SOLVED - I purchased a third-party MiniDP to DVI adapter instead and it works a treat.
Quite what the difference can be to a supposedly passive adapter I'm unsure - but glad it's fixed anyhow.

Philips HDMI to DVI connection....is this possible?

Hi, I just recently got a 32" Philips LCD with VGA and HDMI capabilities. I want to run my 12" G4 PB to it. I have a HDMI to DVI cable that I am connecting via the mini-DVI cable that came with the G4 but I get no signal. I called philips and they had me mess with the resolution to no avail. The customer service rep suggested I make sure the hertz is at 60 but I can't find that on the G4 (newish to macs). Could anyone lend some expertise in this area? Thank you

Found my answer.

HDMI to DVI-D

Hi,
I'm trying to connect an external HP 2510i (WD005AA) monitor to my M6-K125DX HP Envy notebook. I'm using an HDMI to DVI adapter cable but the monitor says it does not receive a signal. The display shows no image en after a while, the monitor goes to the standby mode.
First i returned the cable to the supplier, but the new cable they send us gave the some results. According the specifications of the monitor it is equipped with a DVI-D input.
Do i need a special cable or adapter to connect this monitor?
Could this be cause by single-link or dual-link capabilities of the laptop or monitor?
Hope you can help me out.

H67MA-E35 (B3) HDMI and DVI-D no output

Just did a new build consisting of:
Mobo H67MA-E35 B3
CPU Intel i5-2500 3.3 Ghz
Mem 8GB DDR3 1333MHz
Win7 64bit
I am not getting an output signal from either the HDMI or the DVI-D. The VGA works fine.
I flashed the Mobo BIOS to E7680IMS v11.6 and installed the newest driver for the graphics on the CPU to version 8.15.10.2361
In the BIOS I have the graphics set to:
Initiate Graphics Adapter (IGD)
Integrated graphics share memory (128)
DVMT memory (maximum)
IGD multi-monitor (enabled)
Any ideas on what to do next? Thank you

Glad you got your issue sorted out. I'm am a little confused with the explanation of your solution.
You monitor has only VGA and DVI inputs. Your mainboard has VGA, DVI, and HDMI. Correct so far?
You bought an HDMI to DVI cable, which solved your problem, but your problem was a faulty female DVI on the monitor?
How is this possible? The only way that cable would even fit is going HDMI on mainboard to DVI on monitor, but you stated the port didn't work.
Or was this all done with the new monitor after you found out the DVI port was broken on the old one?
Have you tried the old monitor on a different system to check if it's the DVI port?
The reason I ask all this is if I'm wondering if your issue was really a broken port on monitor, or the MSI display bug that is effecting so many core iX H and Z chipset boards.

DVI-D - HDMI switcher - DVI-D

Hey friends,
I've got a fairly convoluted and confusing HDMI situation. As DVI matrix switchers are so expensive, I decided to get a HDMI switcher and HDMI to DVI cables. I have two Mac Pro towers, each with two DVI outputs, and two 24" Cinema HD displays. So, my signal flow is:
Mac Pros - DVI to HDMI cables (x4) - HDMI matrix switcher - HDMI cable - HDMI to DVI adaptor - Cinema HD tail
The monitors simply flash three short lights, which Apple support tells me means that they are recieving an invalid format or resolution. I thought that HDMI and DVI were completely compatible formats... Any ideas as to why this is not working?
Thanks!

Going through a lot of "adapters" in that setup (cables "adapters", switcher, dvi adaptor). I guess my first question would be to supply all the details of all those components to verify they are the proper components to handle the signals. So, list url's to all the stuff:
1. dvi-to-hdmi cable
2. hdmi switcher
3. hdmi-to-dvi adaptor
4. hdmi cables (including lengths)
Maybe there's something in the specificaions of these things that would indicate the problem.
Update:
As an experiment you might want to try a single monitor and macpro without the switch. mac pro --> dvi-to-hdmi cable --> hdmi-to-dvi adaptor --> monitor. If it works then obviously the switch would be the culprit.
