Feels cheaply made, but works. Incompatible with Radeon 5870!,
Amazon Verified Purchase(What's this?)
This review is from: ATLONA AT-DP400 Dual Link DVI to Mini DisplayPort Converter (Electronics)Picked this up to hook my PC up to my 27" iMac because the Radeon 5870 in my PC will not communicate with the iMac over DisplayPort. The dp-400 does work, but with the 5870 it refuses to go any higher than 720p. I tried to use Powerstrip to force the resolution, but had no success. I also booted in to Linux and added the proper resolution (2560x1440) to xorg.conf, but it still refused to go higher than 720p. I hooked it up to another machine which has a GeForce 210 and it worked right away at 2560x1440. It may be possible that this device will have issues working with other cards in the Radeon 5xxx line seeing as almost the whole 5xxx line refuses to work with Apple displays over DisplayPort like the 5870. The 5870 has been out long enough...this incompatibility should have been made known.
The build quality of the device is poor and the box that it comes in is full of typos. I almost thought I received a Chinese rip-off. The device itself is made of plastic and is held together with a few plastic clamps in the ventilation holes. The two halves of the casing move around a little and feels like it could fall apart quite easily. Although the device does work (as long as you don't have a 5870), it is definitely not the quality you would expect of a $150 converter.
The picture quality is perfect. There are no artifacts nor any lag from the converter and the fact that it handles audio as well is a plus (I did not notice this until I got it).

I wish I read reviews more carefully before buying.
I have NVidia NVS 5200M. This device works only in 1280x720 resolution. Forcing higher resolution via NVidia panel makes it work in 2560x1440 but all pixels are blurry.
It doesn't work in 1920x1080 at all.
Native resolution of my DELL monitor is 1920x1080 and it works fine with my video card.
Very disappointed with false information in the description of this converter.

The same exact thing happened to me.... Poor information provided by this company.. They should let us know which PC Video Cards will allow max res.

The name of the product is "Dual Link DVI". Did you look at the specs of your video card to see if you have a dual-link DVI model? Personally I don't think that's the responsibility of the adapter manufacturer.

I'm having the same issue as you, however it is not the graphic card but rather AMD's drivers. I get the full resolution without any problem when I boot into ubuntu.
