I had a 2006 Mac Mini with native DVI and I had it plugged to my 22" Acer Monitor with DVI input. The display was perfect, sharp, great!
Now when I connected the new Mac Mini using the included HDMI to DVI converter, the image almost look like VGA (not that much, but still, not quite near the image I get with the old Mac Mini. That doesn't make me happy.
What could be the problem? why does the old mini looks better on this monitor?
Wilfredo.
Apple and others also make a mini-DisplayPort to DVI adapter. Perhaps it would be the better choice.
Have you confirmed that the Mac's display resolution settings are set to the monitor's native resolution? If not, make the appropriate settings. If the correct resolution is not appearing, there's probably an issue with the monitor being correctly recognized by the Mac, which may be caused by a defective cable.
Regards.
Resolution is set correctly at 1680x1050 @ 60hz, also the monitor brand and model are recognized. The DVI cable is fine, because the old mac mini looks incredibly good with that cable.
I will try the mini-display port adapter and see what I can get.
Thanks.
Wilfredo.
It's possible that it's the HDMI to DVI adapter is defective.
I found this post because I am having a similar issue with my 2011 mac mini. I have it hooked up out through HDMI-DVI adapter to my 23" Samsung LCD Monitor. Every now and then for no apparent reason, the screen blinks off and then back on again. Its random, it did it when opening up safari. It cannot be the monitor as Ive used this for a while and it didnt happen with an old PC i had attached to it, but that was a DVI output out of the PC also.
Also, worth noting, I went to the apple store and had them switch out the HDMI-DVI adapter, and it still does it. Not sure if its it the HDMI Port or something to do with video chip.
Could be monitor power supply or cable.
I only challenge that suggestion because Ive never had a problem with it before. It seems unlikely or too coincidental that the power supply or cable I use is bad only when starting to use a mac hdmi-dvi out.
I also connected this to my apple TV and ran it for a while with the same adapter and havent seen issues. I think its the HDMI port itself, or something to do with video processor.
But ty for the reply.
Same problem here.
I have a LG LCD TV.
hdmi-dvi connection is awful, even worse than vga connection.
But thunderbolt connection using mini-dp to dvi adapter is ok.
I have the same problem too with the poor HDMI/DVI display quality.
I purchased a MacMini some 2 weeks ago and retained the relatively new Samsung monitor (model B2430 Sync master, which has a DVI and a HDMI port). The said monitor works perfectly with my "old" Windows PC and IMO the picture quality was relatively good and acceptable via DVI-DVI connect.
However I have problem when I tried connecting the Samsund with my MacMini via HDMI to HDMI - the Mini is unable to detect the Samsung. Fyi, I tried swapping the HDMI and monitor cables, swap monitors and change display resolution but to no avail.
It is works when I connect it via the HDMI/DVI option, but the display quality is lousy and not as sharp as I have expected (compare to "old" Windows PC).
This is my first Mac and just kinda of disappointed with this.
Thanks & Rgds

I don´t know if this might shed any light here, but after spending more than 2 months dealing with no-display issues on the same type of machine (Radeon 6630 adapter), the mini finally decided not to display video at all, even after going through all recommendations from Apple (resetting PMU, SMC, Parameter RAM). I have an LG 22-inch monitor.
Fortunatelly I had a spare HDMI-DVI adapter (not from Apple), so I decided to give it a try, and to my surprise it started displaying video again. After that, I switched back and forth between both adapters and finally concluded that the Apple HDMI-DVI adapter was bad. The funny thing is that the problem did not happen all the time, which made trobleshooting very difficult.
Cheers

I am now also having the no video problem over hdmi-dvi from apple adapter. I have to start the mac with the monitor with no video, with the ipad / VNC I click on detect displays and after that I restart. After that restart the video comes back. I have to do this everytime I turn on the mac.
I am going to purchase another adapter from another brand and will report back my results.
Thanks for the update. Drives me nuts that it doesnt work. I had to end up using a mini display to vga adapter to get it to work with no problems.
aaaargghh, just bought my first mac ever, because I want to start developing apps for the iPad.
The HDMI-DVI adapter was included, bought a 25 euro DVI cable, connected it to my HP Compaq LA2405wg monitor and, nothing!
Bought an Apple VGA adapter (another 29 euro) to connect to the monitor, connected it, nothing!
Monitor works just fine with my Windows 7 PC.
Connected it at the office with a HDMI cable to another monitor, Mac Mini works.
But my monitor at home at home does not have a HDMI connector. Tried it again at home, stil nothing.
Anyone any ideas about why my Mac Mini does not work with the HDMI-DVI and the VGA adapter? This starting to get a very frustrating and expensive start with Mac computers....
I am using a standard Female HDMI to Male DVI Converter for my DVI Monitor and a standard HDMI to HDMI Cable for my Mac Mini 2011 and It is work . For a VGA Monitor I Use the Apple MInidisplay to VGA Adapter connected to the Thunderbolt port, and It is work very good.
Sorry for my English.
