I just got my Sammy HDTV/Monitor, which is a 23" 1080p HDTV. However, when I connect my MBP via my mini-displayport to HDMI adapter, the screen gets cut off on the top and the bottom. I have tried to switch the resolutions from 1080p to 720p, but it still does the same thing. It gets off both when I use the external as a secondary monitor and when I mirror the displays and use it as a primary monitor. When I turn overscan off in System Prefs, the 1080p image shrinks and there are black bars around all sides (however, it does show the entire screen). Does anyone know how to fix this? I want to get the most out of my recent purchase, and I know this is possible because I've seen it. Thanks.
 
Strange, you definitely want overscan off, but you shouldn't have black bars around all sides. The mac should detect the native resolution and everything should work fine. At least it does on my 50" plasma.

But then I read this: https://forums.macrumors.com/posts/5838767/

Sounds like there are some strange combos that just don't work right.
 
Well I just solved it. I had it connected previously through HDMI, but I tried it using a VGA cable and it works. Weird but it works for me. I appreciate the reply tho. I probably should have tried that earlier but I never figured that was the issue.

I am also connected to a Sammy 23" HDTV with my 15" i5 and VGA works very well...I like using the clamshell mode with my Magic Mouse and Apple Wireless keyboard...perfect combo
 
same issue.....

So I bought my mom a new macbook pro 13" with a samsung P2370HD monitor. I bought a Mini Display Port to HDMI adapter to hook up the monitor. I'm having the same issue that was described, it cuts off the menu bar and there are black bars on the side as well. My bigger concern is that the picture quality just isn't great. This setup compared to my own imac 21.5 inch display seems like night and day. The picture just seems pretty pixely and not very crisp. When you switched to using the VGA cable did you notice any difference in the picture quality? Just comparing the two I feel like I'd rather look at the 13" inch screen on the macbook than the 23 inch monitor which obviously defeats the purpose.
So...I just spent $20 on this MiniPort to HDMI adapter, was that a waste? is there no way to get it to work properly? Is VGA the only way to go with this setup? Thanks.

Well I never did get it working with my HDMI cable and adapter, so is it possible to return the HDMI adapter? In terms of picture quality, the VGA is heads and shoulders above the HDMI (this should not be the case, but it is). My MBP automatically detects the 1080p resolution when I connect it (with a few exceptions but you just disconnect it and reconnect it and it will work) and the whole screen is shown. The HDMI looked terrible on it. However, that was just with connecting my computer because my friend hooked up his xbox 360 to it via HDMI and it looks great. Unfortunately, I think VGA is the only way to go for this monitor, so you'll need a Minidisplayport to VGA adapter (I got mine from Apple because I didn't want to go messing around with crappy third party ones and have them fail on me) and a VGA cable, which you can get for pretty cheap on Amazon or something.
 
I'm having exactly the same problem!

Just got my Samsung P2450H 24" monitor and I bought a mDP -> HDMI converter, as well as a HDMI -> HDMI cable, and I can't get the maximum resolution to display properly on the external monitor. The pixels look blurry as well and not as sharp as I would have liked. Plus, I'm experiencing the same problem with the edges being cut off.

I've actually heard contrasting reports saying that mDP -> VGA does not work on Samsung TVs/Monitors, and the DVI on the other hand works perfectly. I need to get a new converter now, but I'm having doubts as to which one will work nicely.

Another question. I need to be able to get audio out from my MacBook Pro to the external monitor. The newer MBP have the ability to combine audio and video out using the mini Displayport. Now, there are some 3rd party cables that supposedly get the job done by simply providing a mini Displayport to VGA/DVI slot, but I'm a bit skeptical about this.

Bump. Kinda need a quick response so that I can order a cable in time for Christmas!
 
just registered to help you guys out as I once had a similar problem connecting a windows pc to my p2370hd, its in the settings of the monitor:
In the menu --> input --> sources --> select HDMI and then press extra and set the HDMI device name to pc, this way the monitor doesn't apply overscan and the image should be normal.

hope this can help you
 
Thank you very much! The settings were different from mine, but I think the main problem was the monitor being set to AV instead of PC. I changed this, and now the clarity is much clearer!
 
i had similar problem!!!

MBP and Samsung P2370HD

I just solve it, I'm using MCP 13", Samsung P2370HD via HDMI, when I connect the monitor automatically my mac detect it at 1080p resolution, the image looks fine but the text looks very fuzzy.. weird.. So, I change the monitor picture size to 16:9 and then I went to system preferences - displays and use a little underscan to reduce the resolution because using 16:9 it's a little bigger than my display.. and voila.. it's working like a charm using HDMI at 1080p

If you need something just write..

Cheers...
 
Thanks and my two cents

Thanks to all of you on this thread, I was finally able to connect my Macbook 2008 to Samsung 46" HDTV just purchased. I have summarized the steps I took below for my self (I had to check the Mirror Displays box on Mac preferences per below, without which the connection did not work--that is my only addition to the advice you all gave). Thanks!

To connect Macbook (2008) to Samsung HDTV (2011):

1. Shut down the Macbook and HDTV (no need to disconnect power cord).

2. Connect adapter/cables:
a. Video from mini-DVI port on the Macbook, to the HDMI/DVI (Port #1, lowest) on the Samsung HDTV, and
b. Audio from headset output on Macbook, to PC/DVI “Audio In” port just below the HDMI/DVI input on the Samsung HDTV [Do NOT use AV Input port closer to the center of the Samsung HDTV].

3. Power up the computer first and, when fully done, then the Samsung HDTV—so the Samsung HDTV can recognize the Macbook when the HDTV is powering up.
a. If the Samsung HDTV is not on HDMI/DVI (Port #1), press SOURCE on its remote and scroll to this port.
b. The Macbook screen will appear on the Samsung HDTV
c. But text, audio or video on the Macbook may not appear on the HDTV. If this happens, do the following:

4. On the Macbook:
a. Click on System Preferences
b. Click on Displays
c. Displays, Arrangement, Color will appear on the screen
d. Click on Arrangement
e. Two overlapping screens will appear
f. Check the Mirror Displays box at the bottom of the screen
g. Text, audio and video on the Macbook screen will appear on the HDTV.
h. You are done!
