Just an update, I connected the MBP to the TV using a VGA cable and the DVI to VGA adaptor that came with the computer. Works nicely and the picture quality is markedly better than using the DVI to HDMI cable. But I'd still like to be able to connect through HDMI and my receiver, so any help with getting true 1080p through the DVI to HDMI cable would be great. Thanks!
I have the same problem.. tried on two Full HD LCD Samsungs using a 6' DVI/HDMI cable I bought at the Apple Store. In both cases DVI/HDMI drops to interlaced.. I suspect this isn't the issue however what do the pins on the DVI-side of your cable look like as per: http://www.datapro.net/techinfo/dvi_info.html
(see end of page)
I'm going to test w/ more cables however I think this might be an OSX issue as my friend is having the same issue w/ a Mac Pro (Nvidia 7300 GT)..
It is interesting subject for me as well since I have bought Sony Bravia 40X3500 and I am waiting for cables came through. I got DVI to HDMI crossover.
The thing is I have ordered HDMI v1.3. Apparently those version of HDMI cables are design for 1080p. But I will see myself next week and I will tell you about my experience.
Others have reported that 1080p is a missing option within Displays preferences and have found the following procedure to restore 1080p as a selection, though I don't understand why it works. Anyway, here is the procedure to try:
With the TV hooked up through the DVI port, go into Displays preferences and click on the "Show displays in menubar" checkbox.
Go the the resulting icon in the menu bar and click on it to drop down the menu
Select "Number of Recent Items" and set it to 5 (or 10?)
After doing the above, you may have to restart. Some have claimed that the above procedure causes a 1080, 60 Hz (1080p) timing to show up in Displays preferences. Good luck.
Hi guys, I just got my Samsung LE40M87BD working on my MacBook Pro running Leopard in full 1080p resolution. Steps:
Install DisplayConfigX from www.3dexpress.de
Select the correct monitor in the top dropdown list
Under Monitor, my settings are (mostly default):
Refresh rate 45.00-61.00
Horizontal frequency 10.00-120.00
Pixel Frequency 138.50 (specified in the Samsung manual)
Default refresh rate 60 (specified in the Samsung manual)
Under Resolution, I created a new setting:
Kind = Timing
1920 Active 1080
48 Front Porch 3
32 Sync 5
80 Back Porch 23
Untick Interlaced if it is ticked!
Select Pixel Frequency and type in 138.500
Check the following (if the numbers are not correct, you have made a mistake above):
Check that Horizontal is 66.587 KHz (specified in the Samsung manual)
Check that Refresh rate is 59.934 Hz (specified in the Samsung manual)
Go to Install, click Install
Restart the system as suggested
Your monitor not here? The challenge is to find the Front Porch, Sync and Back Porch settings that work for your monitor. The trick is to check if they are in the manual, and if not, assuming that the horizontal and vertical frequencies are, Google the horizontal and vertical refresh rates - they are pretty certain to yield the right settings! E.g. I Google'd '66.587 59.934 front porch'. Alternatively, try this if you are more technical: http://www.vesa.org/Public/CVT/CVTd6r1.xls
Hope this helps!
Thanks for the tip! Only 1920 x 1080 (interlaced) was showing up in my display settings for my HDTV. For a while I was a little disappointed that the settings did not go higher to 1080p (non-interlaced). But for some reason setting the "Number of Recent Items" to 5 or 10 shows an additional resolution. It now shows:
1920 x 1080, 50 Hz (PAL), Millions
1920 x 1080, 60 Hz (NTSC), Millions
1920 x 1080, 60 Hz (NTSC), Millions
The second 1920 x 1080 resolution is sent to the TV as 1080p!! The Display preferences panel still states that is is the interlaced setting, but just ignore that. Thanks again for the tip, and I hope that the setting becomes standard in the settings in the future.
