MacBook Pro DVI-HDMI 1080p doesn't work correctly

Hello,
I've just bought new Samsung LCD TV LE40B550. This TV is Full HD and support 1080p. I've connected it via DVI (macbook pro) -> HDMI (TV) cable. It works ok, when I set 1080i. But when I set up 1080p, it shows few dots (pixels) on TV not correctly. The picture is not that good as 1080i. Shouldn't it be reversely? The 1080p should be 1080i, shouldn't be?

You probably want to post this in the MacBook Pro forum:

Theres almost a trick to it for first time users, goto SETTINGS...General......Cellular (if Verizon) ....Personal Hotspot, turn it on.....turn on wifi on your Mac, select your Iphone. Enter password.
If you take too long doing it, youll need turn turn off and on real quick the "personal hotspot" slider on the Phone.......then go quick again thur the Mac.

Macbook Pro, Leopard, & Graphire4--it doesn't work

I have been reading the posts for the wacom tablets, and I have deleted the tablet driver, repaired permissions on the HD, installed the lasted driver from the Wacom site, have a powered hub, since the hub on the macbook doesn't have enough power, and I have restarted the computer. All of this is done on my Macbook Pro with Leopard. When I click the pen tablet in preferences, it says a supported tablet can not be found. Does anyone have a solution? I'm at my wit's end with this.

I have MBP-17, Leopard 10.5.2, Wacom PenTabletDriver 5.0.5-3, and it seems to be working fine (also in 10.5.1), from powered hub and directly plugged. Didn't have trouble on PBG4-12/Tiger, either, with lower USB power.
This sounds like bus power problems. Have you tried resetting the SMC followed by a couple of unplugged cold reboots, then hot-plugging the Wacom by itself to a different USB port than usual? That should help calibrate problematic bus power tolerances... see these articles:

Core i7-2720QM on Macbook pro 2011: Turbo Boost doesn't work! It's possible?

I test my core speed with MacCPUID that show real time cpu frequency. I try it in normal condition and running extreme application. Everytime my cpu frequency is something like 2.199 - 2.200 but never more than 2.200 ghz.
So I have to think that Turbo bost is not active on macbook pro and all the things in apple website about this feature are false!
Is it possibile? Who knows something more about this?
Greetings,
Stefano

Yes, there is Turbo Boost active on all MacBook Pros. There is no real way to measure turbo boost unless you're in BootCamp, using Intel's Turbo Boost Monitor. The Intel website states that not all CPU measuring software will correctly display the turbo frequency because it's either not current, or doesn't support turbo boost. If you have BootCamp installed go ahead and search Intel Turbo Boost Widget. download, and install it, this will give you correct results. You can't really measure turbo in OS X.

Macbook Pro Retina - nVidia card does not work correctly

Hi,
having a MacBook Pro Retina. It ran fine till yeasterday when I fired up a game which was laggy and it was running fine before. It took me several hours to find where the problem is and it seems to me that the nVidia dicrete card is not working. But strangely not working. I installed gfxCardStatus to see whether the card is being switched to run the game and it actually is. But the performance is the same as running it on an internal Intel. I took another test and downloaded CINEBENCH to see the differences and sadly the results are the same if I switch to nVidia or to Intel and run the benchmark.
Obviously something is not right here. It happened over night. Before it worked corectly. I do not remember installing something that day/night that could have broken it (in case it is a SW problem). Only one thing comes to my mind - Apple Java update. But I tried to uninstall it and got the same result. I did try to restart several times. But otherwise there is no visible flaw, e.g. flickering or black screen when swithech do nVidia - nothing. gfxCardStatus shows that the system switches the card and I notice no change. Only in heavy load it is obvious that it is slow (slower than it was).
Is there a way to see if the nVidia card is working? I suspect that even if the system is trying to switch to a discreet card it still runs on the Intel in reality. Any way how to distinguish this rather than to rely on gfxCardStatus? Any log that would make this clear? Any test I can run (Apple HW test shows "no problem detected")?
Many thanks for hints.

To show what I am talkin about I did another test. I downloaded and ran LuxMark. There it is possible to test CPU and GPU separately on a same benchmark scene. FIrst I let the system switch to nvidia and did the test:
Then I manually switched to Intel/CPU in gfxCardStatus and also selected CPU in the LuxMark and did the same test. The result is:
You see? How it is possible that in OpenCL computation CPU with internal graphic card is even faster then the descreet one? This is what I am experiencing now and cannot figure out where the problem lies.
Would the Apple HW test discover a dead nvidia card? Because nothing shows that the card is dead but as you can see it is not performing as it should.

15 inch Macbook pro Retina HDMI port will not work

One day it was working fine then all of a sudden the screen when blank and i have not been able to get it to work since. I use to plug the HDMI cable from my MAC to my TV now there is no acknowledgement on my tv and my MAC will not detect that a cable has been connected like it use to. Please help.

If available, try connecting to another TV, try another cable and/or another Mac. An appointment at an Apple store genius bar can determine if the fault lies with the MBP. There is no software solution in this case.
Ciao.

Macbook Pro SD Card reader doesn't work

Hey all. A few weeks ago I plugged in my SD card like I've always done, but my SD reader didn't work. I've tried SMC reset and PRAM reset. Nothing works. The SD reader doesn't show up in apple system profiler nor in Disc Utility. I've tried different SD cards.
What can be done?

i tried that since Yosemite killed my SD Card reader... its so annoying. i don't even know if its a hardware or software issue. however, the check didn't worked... and all my 3 SD Cards are working well...

The macbook pro keyboard media buttons doesn't work for itunes

hi,
since i installed the snow leopard the buttons doesn't control (play, stop, forward...) the itunes.

Hey ARM77,
Welcome to the BlackBerry Support Community Forums.
There is a few things I will suggest to hopefully fix this issue for you.
1. Is mass storage mode currently enabled when you hook your BlackBerry to the Mac? If not please read KB13564.
2. Is your iTunes updated to the very latest version?
3. Verify that your media card has a sufficient amount of memory available for the playlists. To check this, perform the following:
In BlackBerry® Desktop Manager, click Device Options. On the Media tab, decrease the amount of memory that is kept free for files other than your music files.

Macbook Pro 15" - clamshell mode doesn't work after installing Mavericks

So I've upgraded to Mavericks, but my late 2011 MBP 15" has stopped working in clamshell mode (closed lid with external display on) – display just does not detect an input after closing the lid. Anyone experienced this?

This was het same problem as in upgrade to Mountain Lion before... Apparently the NVRAM reset should fix this (PRAM-reset for non-intel based macs)
>>>
OK, after upgrading to 10.8.2 and then doing a PRAM reset gives me clamshell mode back!
