HDMI vs DVI on same monitor

I just bought a mac mini(2010) and connected mini to samsung P2270HD(Full HD 1920 X 1080) via HDMI gives a very bad picture quality. Took the mini back to the store and they reproduced the problem on the same monitor. Then the guy took a dvi cable and via HDMI-DVI adaptor connected it to the same monitor but on DVI input. Picture quality was fantastic.
Now why did that happen? Same HDMI port but different input to Monitor

I have a Mac mini (new version) connected to a Samsung LN32A450 HDTV via:
Mac mini (mini-display-port) > mini-display-port VGA adapter > VGA cable > TV (VGA port)
And it looks fantastic. I recently got an HDMI cable so I could free up the mini-display-port adapter and connected the Mac mini to the TV via:
Mac mini (HDMI port) > HDMI cable > TV (HDMI port)
And it looks horrible. I tried both HDMI ports on the TV, adjusting various settings on both the TV and Mac mini (resolution, underscan, profiles, etc) and can't find any way to fix it. I've read of similar problems elsewhere and some think it's that the HDMI output on the mini is crappy but your post indicates the HDMI from the Mac mini is fine. Just to confirm, yours looks as good as being connected to a computer monitor when connected to your HDTV like this?:
Mac mini (HDMI port) > HDMI cable > HDMI-DVI adapter > TV (DVI port)

DVI and HDMI feed to the same HD monitor

I am adding a Black Magic Hd extreme card to my Mac Pro and currently have a 23" Apple display only for editing with FCP (I've been using a Sony Trinitron 14 " CRT TV for SD monitoring in the past). I can't afford a pro HD monitor so will be going down the route of an LCD TV connected via HDMI. I saw a 24" 1080i LCD TV yesterday with both HDMI and DVI inputs and wondered if I could connect the LCD TV monitor to the second DVI output on my Mac Pro AND to the HDMI output from the Black Magic card. I could then switch between the two - 1 way giving me extra deskspace when editing and the other way an HDMI fed HD TV monitor. I'd need some sort of switching unit though. Do you think this is feasible ? Would Final Cut get confused ? Can anyone suggest a way of switching between the two ?

Maybe I'm tired...
No, I'm definitely tired, but...
Why do you need a KVM switch? Just switch between the inputs of the display.
OX 10 has no problem if you switch the display from the DVI extended desktop output to something else.
I have both my computer screens on KVM switches and I almost never have a problem making the switch to the alternate side - even while rendering in FCP or Color.
If you must go the KVM route - I really like the Belkin DVI KVM switch with the button on the desktop. I have nothing but problems with KVMs that rely on keyboard shortcuts. As an FCP user they frequently conflict with editing keyboard shortcuts.

How do I connect Monitor without HDMI (but DVI-D) to laptop with micro-HDMI?

I have a Samsung NP900x400D-A02US laptop... the video connections are:
- a micro-HDMI
- a "monitor port" (which the manual says supports 15 pin D-Sub interface.. or you can connect VGA adapter),
I would like to buy the Dell Ultrasharp u2412M which has 1900x1200 resolution.... BUT it does not have an HDMI port. It has:
- a display port
- VGA input
- DVI-D with HDCP Input
- USB ports (but I don't think it's the kind that will allow me to hook up thge monitor to the laptop with USB)
How the heck do I connect the 2 of these... in a way that retains the 1900x1200 resolution? if I can't find a good way I might have to find another monitor with HDMI....
Thanks so much for your help! It's a bit frustrating to sort through it all....

I ended up finding it by item #, because I would have missed it, too. I wasn't sure if the product image was correct until I saw this:
Connector on First End: 1 x HDMI (Micro Type D) Male Digital Audio/Video
You got it figured out. Hooks up exactly like you said. HDMI and DVI will result in same picture quality, but as you mentioned, HDMI doesn't carry audio. They are the same, for all intents and purposes, in all other regards.
The DVI cable should have thumbscrews on each end, to help secure it at each end. The Adapter I linked has 'receptors' for the thumb screws, so the connection will be secure. The monitor should have the same 'receptors' for thumb screws. The weakest point of the connection, physically, will be the Micro-HDMI, so just be careful to not put pressure on that connection.

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!

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).

2011 Mac Mini and Acer x222w monitor incompatible? HDMI to DVI adapter issue

I am totally bummed because I just bought a new Mac Mini thinking I'd be able to use the display from my old system, an Acer x222w, which has both DVI-D and VGA connections. I hooked the monitor up using the HDMI to DVI adapter included in the box with the Mini. On boot, I could see the Apple logo, though it was not centered, and when the set up screen came up to the select language screen, it flashed quickly and then turned to snow.
I was on the phone with Apple support for over an hour trying to troubleshoot this issue. I was a little disappointed that tech support didn't even seem to be aware that the Mini came with an HDMI to DVI adapter. It was then recommended that I try an adapter for the mini display port, which the 2011 Mini doesn't have.
I was able to borrow another monitor, a Dell with DVI-D, and it worked.
I have searched for specs/requirements that might explain why the Acer monitor doesn't work while the Dell one does. I cannot find anything from Apple. I just assumed any DVI connection would work. Has anybody else encountered this problem? Most of the issues I've found on the forums involve trying to hook up to a home theater LCD TV, which I'm not trying to do. If I had known my monitor wouldn't work, I probably would have just saved up for an iMac.
Thanks in advance for any thoughts or tips!

Mac Mini Newbie + Viewsonic VX2450WM monitor. Need HDMI to DVI adapter? What cords needed?

Mac Mini Newbie here.
Getting the Viewsonic VX2450WM monitor for it. There is no HDMI on this monitor, but reviews said it's Mac mini compatible.
Do I need to get an additional cord? HDMI to DVI adapter cable? Does the supplied short white cord inside Mac Mini packaging suffice?
Thank you!

No, the HDMI on Mini only support digital VGA is analogue
Can the HDMI port drive analog displays (VGA displays for example) using adapters?
No. The HDMI port will drive digital connections—such as DVI—using the adapter that came with the Mac mini, but cannot be used for analog displays such as VGA. You can purchase a Mini DisplayPort to VGA adapter separately to drive analog displays.

HDMI to DVI to VGA to Monitor?

I just purchased a Mac Mini and totally forgot that Apple upgraded to Mini DisplayPort (I still have the mini-vga to vga cable on my MacBook).
So what next? Do I have to buy a Mini DisplayPort to VGA adapter? Or can I somehow hook up the Mini to my VGA monitor with the HDMI to DVI adapter that I got in the box?
Also, I have one of these, but it doesn't seem to fit in the DVI:

Dual Monitor HDMI and DVI

I bought a new Mac Mini. I have a Moshi Thunderbolt to HDMI connector and an HDMI to DVI Connector. I want to use one monitor connected to the Thunderbolt and the other to the DVI. When I do this, the DVI Screen works fine but the Thunderbolt one cuts in and out.
Any ideas how to do this or do I need both to be DVI?

Sorry,
The problem above is solved for me.
With thanks to Joseph.( See discussion Mac Mini 1 feb. 2013.)

G41TM-E43 - DVI and HDMI output at the same time?

I am looking to output to 2x 1920x1200 displays...nothing 3D and nothing that needs to be decoded...just some power point presentatinos and some flash within a browser window.
I am pretty sure the resolution isn't going to be a problem, but using both the DVI and HDMI ports at the same time is something I am concerned about. I am looking for people with actual knowledge that this works...no guessing please.
Regards,
Dan

The likelihood is that you won't be able to use DVI & HDMI at the same time, but you could use one or the other in conjunction with the VGA (D-Sub) port.
But as this is a user-to-user forum, and you may have to wait for someone with actual experience of this to see this thread and respond, for a definitive answer, contact MSI Support direct:

But please do post back with the answer, as this could be useful for others in the future with the same question.

1. I didn't really 'get' the 'iX' syntx for the topic .....so any 'i' series socket....yeah makes sense .....maybe put a couple '' for denotation. and a space bar.
2. re: hjking....wasn't intentional ....just typed....'h57m' in the 'search' box. the ' G41TM-E43' only one that came up; so I ran with it.
this is more appropriate though.

Re: HDMI to DVI Monitor

I just purchased a K330 with the Nvidia GT420 graphics card. I was surprised that the card did not have a DVI connector. My Samsung 2033 only accepts VGA or DVI while the card has VGA and HDMI. Will a standard HDMI to DVI cable allow the mnitor to operate in digital mode?
Thanks.

I bought a HDMI-DVI cable and hooked it up. It works. I'm going to remove the video card and install my GT430 in it. It worked much better in the Vista 32 bit machine. We'll see.

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.

I cannot get the video output from the HDMI to work. I have been using DVI to DVI and replaced the cable with HDMI, however only get a "no signal" message when I try to. I have adjusted the input type on the monitor to HDMI but nothing is being displayed. Is there anything I need to do to output video on HDMI (I assume it should happen just by plugging in)? I haven't had a chance to test the monitor on another PC as yet, but this will be my next option.
Any suggestions welcome.

Yes, I initially set it up with the HDMI as the only connection, but I also tested having both DVI and HDMI connected at the same time - in this case it detects the model number of the monitor through HDMI and gives me the option for extended desktop etc - however, if I try selecting duplicate screens and then cycle through the input types on the monitor, when it gets to HDMI the screen is just black.
I'll swap the monitor with my TV when I get back home tonight and see what the results are then.
On other thing issue (probably unrelated) is I get noticeable ghosting, especially when scrolling down webpages (dark text leaves a white silhouette) - I'm using the same DVI cable and monitor that I was on XP, the only difference being the OS and the graphics card.

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.

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.
