MBP w/ Retina - External monitoring problems

Brand new 2.6GHz MBP Retina, 500GB SSD, 16GB RAM...

Upon connecting an HP Dreamcolor 24" display via Displayport and HDMI, all text is jagged, aliased. Images and movies themselves look OK, though when I move them between the laptop screen the Dreamcolor, the colors flicker a little, as though changing colorspaces. Never saw this before when connecting my 2007 MBP via DVI.

Changing all resolution options for both displays did not affect the issue.

MacBook Pro with Retina display, Mac OS X (10.7.4)

Hi,

I'm seeing this too. Retina Macbook Pro -> HP LP2475w via HDMI at 1920x1200. The text is jagged although screen graphics look ok.

If I connect to the same screen using Mini Displayport to DVI then it looks fine.

Did you find any solutions?

Cheers.

Support was not very helpful. They said it's a scaling issue, but scaling is blacked out for me. I was able to make it slightly better by using an HDMI to DVI connector. That it least got the color to full RGB (vs. YUV), but scaling is still blacked out, and because its DVI it's only 8-bit. Apple apparently does not have a 10-bit RGB monitoring solution for this machine -- unless one is to use an external video adapter (i.e., Ultrastudio 3D).

I also tried an HDMI to DVI connector and that worked ok - seems to be HDMI to HDMI where the problem lies.

I'm going to wait for Mountain Lion which is not far off now and hopefully has better handling of retina/hdmi macs.

I have the setup as you, and this is not only a font aliasing issue – I see some sort of unsharpening effect (like the photoshop filter) on every element edge, accross the board. That happens only when using the displayport port on the display. I thing is just a poor displayport implementation on the LP2475W, once I did not have the same issue with other HP displays over displayport. And by the way, it all works fine over DVI with an original Apple mini displayport to dvi adaptor.
