josh256 Posted January 5, 2008 Share Posted January 5, 2008 Curious if anyone has gotten their Mac to nail 1080P (over either DVI-D or DVI-to-HDMI)?? Have tried a MBP and a MP on a couple FullHD/1080P Sammys (HDMI 1.3) and haven't gotten above 1080i so far. *** EDIT: Got it sorta workin'. Looks like a lot of folks had issues from 10.4.10 onwards w/ it dropping/forcing 1080i (apple changed EDID driver behavior): http://discussions.apple.com/thread.jspa?m...32 Anyhow, can't get the picture to align (nor can most others). w/o overscan I have columns/borders, w/ overscan my hdtv is cropping the oversized output (as it should I suppose). *** Link to comment Share on other sites More sharing options...

josh256 Posted January 6, 2008 Author Share Posted January 6, 2008 I thought HDCP was optional... (EDIT: EG. HDCP device doesn't require HDCP transport, only HD-DVD/Blueray playback does) so w/o HDCP 1080p should still be possible over DVI.. (I'm pretty sure my card supports HDCP anyhow...)

ph363 Posted January 10, 2008 Share Posted January 10, 2008 DVI to HDMI with mbp works great. 1980x1080 fits the screen perfectly. Link to comment Share on other sites More sharing options...
josh256 Posted January 10, 2008 Author Share Posted January 10, 2008 What are your settings (mirrored vs. extend, overscan) and what model TV are you connecting to (My MBP as well as both my friend's require overscan enabled to fill the screen [which drops/crops a bit of the desktop]) J Link to comment Share on other sites More sharing options...
ph363 Posted January 10, 2008 Share Posted January 10, 2008 extend with overscan. The tv is a panasonic TH-42PZ77U I also have a last gen mbp with an ati gpu. Link to comment Share on other sites More sharing options...
josh256 Posted January 11, 2008 Author Share Posted January 11, 2008 yeah extended w/ overscan is likely overrunning your tv borders too and you haven't noticed. To verify: Open quicktime play something and select view: fit to screen.. you should loose the quicktime frame and some of the video (compare to fit to screen on the MBP screen, or when using a DVI to VGA cable instead of HDMI). The bigger problem is there doesn't seem to be any way to achieve 1:1 pixel mapping over DVI-to-HDMI for 1080i/p.. so whether or not you care about loosing ~10% of the screen the remaining 90% is far from perfect pixel-wise. EDIT: I have the same MBP I think (Fall 2007) Link to comment Share on other sites More sharing options...
ph363 Posted January 11, 2008 Share Posted January 11, 2008 Im not getting any over run. I tried quicktime, vlc, mplayer, and a few browsers: none of them were cut off. I even set up geektool entry's in all four corners of the screen...nothing was cut off. Maybe it is a scaling issue with the tv? Link to comment Share on other sites More sharing options...
josh256 Posted January 14, 2008 Author Share Posted January 14, 2008 Awesome dude.. looks like it was the "Mirror Displays" option that messed it up for me (I thought I needed mirroring to get full-screen games running on the TV but didn't). When in mirror displays mode my MBP is not nailing 1080 because the LxW ratio on the MBP is not 16:9.. Now when I run extended w/ overscan I get a perfect fit now (and the picture is perfect pixel-to-pixel using Samsung "Just Scan" option so I'm not sure why it's called overscan since it's clearly outputting a perfect 1080p). Since most games only run full screen on primary display I was also able to switch the external display to primary by dragging the toolbar over from within the display->arrangement tab.. Thanks dude - **EDIT** Posting my calibration settings for use on an LNT-4661F 46" 1080P display: TV: Dynamic, Contrast 100, Brightness 45, Sharpness 0 <-- IMPORTANT, Color 55, Tone Cool1, NR/Active/DNIe all off <-- also important Also set HDMI black level to normal Mac: Extended desktop + overscan + show displays (necessary to access both interlaced and non-interlaced modes), Ran manual calibration but can't tell the difference from the EDID default Samsung profile so no biggie Link to comment Share on other sites More sharing options...
