External samsung monitor slow

I have just bought a SAMSUNG TA300 - 27' monitor.
I have two problems - the screen seems great when playing video. But is not sharp compared to the LCD on MBP. I have already done all the obvious and suggested on the forums - that is use DVI to DVI cable ; also edit name to DVI PC, placed in 1081i NTSC 60HZ mode. Spent more money on buying two adaptors as well, the second being the Apple overpriced miniDV to DVI adaptor.
All of these thing helped greatly, but it still seems that the sharpness of the text on the screen is not great. In fact it seems like 'vertical bands' of blurriness across the screen. The bands appear to be about 3 cm across. Can see it now on as I am typing this text.
The second problem is that the mouse is slow when I have a browser page up on the screen. All activity seems to be slightly delayed. As I switch the browser to the MBP screen, it is all okay.
Can anyone help with these two problems ?....would really appreciate it, feeling desperately ****** off after spending best part of £275 on something that doesn't seem work and aggavates me everytime I switch the computer on.

I have solved one part of the problem with an amount of fiddling of the various controls.
1. You have to set the 'display preferences' to 1080p NTSC.
2. On the monitor, set the input to DVI PC by 'EDIT NAME' under the input menu on the monitor.
3. On the display preferences, make sure that the underscan is set to 0. This was causing the blurring in vertical bands. Also now the display area on the monitor occupies the full screen without need to resize ( this is why I had adjusted the UNDERSCAN setting in the first place).
The slowness of the display seems to be okay now. I am still testing that aspect. BUt the above seems (I really hope so) that problem as well. Thank God ! I was really getting frustated overall with the new monitor and considering going out to pay the extra £500 for the Apple Thunderbolt. Certainly, in some ways can understand the need for the extra pixels on the Apple display when you get into 27" monitor range.

Connect MBP to external Samsung monitor

Hi all, I see similar q & a's but not exactly this :-
I have a late '09 MPB (pre thunderbolt), I want to connect to a Samsung SyncMaster 940MW.
I currently run 2 of these synmasters as a dual display for my MacPro with no problems using two DVI cables.
I purchased a (I admit 3rd party) Mini DVI to DVI adaptor and I get no picture - just black screen
I am not sure if that's the correct name for the port on the MBP but its the correct plug on the adaptor cable.
The DVI end is the same dual link DVI as mates with the cable to the monitor.
Not sure if i've described it well enough, and I don't think I can put a picture of the adaptor cable up?
Any ideas folks?
Thanks Graham

Mini-divi? According to MacTracker 2009 MBP's have a mini-displayport. So you need a mini-displayport to single link dvi adapter (since that monitor's max resolution is only 1440 x 900).
Assuming you are just wrong about the terminology because I don't know how you could plug a mini-dvi into a mini-displayport anyhow make sure the mini-displayport plug is pushed firmly in so that essentially all the metal part disappears inside the socket. Mini-displayport plugs can be a little tricky in that you need to make sure the plug is fully seated in their socket.
On your computer, if you open the Displays preferences and do not see an Arrangement tab (or there is an Arrangement tab that shows only a single monitor) then there is something physically wrong with the connection. Try clicking Detect Displays just to see if the computer can now sense the presence of the connection.
If you do have an Arrangement tab, and it shows two screens, then click Gather Windows to bring the monitor's Displays preferences on to your main screen. Set the proper resolution (1440 x 900 I hope is shown). Set the refresh rate if that preference is shown. Hopefully you should see a picture at this point.
The DVI end is the same dual link DVI as mates with the cable to the monitor.
They all are physically compatible. They only differ by which pins are used. See the pictures here.
Dual-link dvi adapters look a bit different and require additional power supplied by usb. You only need dual link adapters if the video resolution is greater than 1920 x 1200.

MacBook Spring 2010 Snow Leopard won't work with External Samsung Monitor

Hi,
I have a MacBook I purchased about a month ago and it's not working with my Samsung SyncMaster 940 BW. I am using Mini DisplayPort out with a Mini DisplayPort-to-VGA adaptor which goes into my SyncMaster Monitor. I have tried rebooting, and also playing around with my laptop resolution, but otherwise I have no idea what to do about this.
I've read on the discussions that this is a known Snow-Leopard issue but I thought I might post to see if this has been resolved. I run all the updates but the monitor still isn't working?

A better place to post would be in the The MacBook Pro Display (2008 and Later) forum:

External HDMI Monitor Slows Down Macbook Pro to Unbearable Speeds?

I have my 2011 17" macbook hooked up via a Moshi HDMI adapter to a 24" Acer 1080p monitor... While the image shows properly it makes the computer completely unuseable. I can't play videos and it lags up the machine really bad. I don't get it... i paid $3000+ for this machine and it can't output a smooth HDMI signal without crushing the system? Is this happening to anybody else? Any solutions?

Yeah i was just about to post the Activity monitor before / after results.... here is what happens.. the results are stunning to say the least:
PRE-Thunderbolt-->HDMI Adapter:
CPU:
User - 1.5%
System - 2.5%
Idle - 96%
Memory:
Free : 5.9 gb
AFTER PLUGGING IN THE ADAPTER AND HOOKING UP THE MONITOR
CPU:
ALL CORES JUMP TO 80% +
%USER: 4.25
% SYSTEM: 77.33%
% IDLE : 16.70
Memory remains stable.
THE PROBLEM IS OBVIOUS.
Something is causing the system CPU to become completely innefecient. It takes about 10-30 seconds for this proccess to occur. At first, the CPU remains low, but as soon as any content hits the second screen every core jumps to being 70-80% occupied, and this is JUST with firefox running.
Any help? Could apple store do anything to help me out?

MacBook Pro 10.8.2 stopped detecting external Samsung monitor

Hello,
My MacBook Pro stopped recognizing my extenal monitor that I use as an extended desktop. I plugged the same monitor into my old machine and it worked fine so I know it's not the monitor. I reset the PRAM and ran disk utilities to repair disk permissions and that didn't help. I have tried every combination of plugging and unplugging the devices I can think of. I am pretty sure the cause if this is a system software update and not the hardware.
Any suggestions?
Thank you!

Crap, same thing here, I used to be able to connect my MBP Late 2008 to Philips hdtv with no problem using Snow Leopard, but as soon as I upgraded to Lion it wouldn't work. I was waiting for Mountain Lion to come out and upgraded hoping for the feature to work again but no success. Money spent on cables are being wasted. Any fix soon to sort it out?

External LCD Monitor Flickers for 10 - 15 minutes before it settles down

I have a Lenovo 3000 N100 with a samsung syncmaster 931B as the second monitor. When I activate the monitor, it flickers for around 20 minutes before it settles down. I have the resolution set at 1280x1024 32-bit color 60hertz refresh rate.
I've had this monitor for more than one year, without any problems. I've recently updated the nVidia Ge Force 7300 video drivers on my Windows XP Pro SP2 system.
Actually, the problem is not the monitor. I can connect this monitor to a second laptop and it works fine, with no flicker.
I have PC-Doctor 5 installed and the video tests for the nVidia GeForce 7300 and the external monitor itself ran with no problems.

I have a similar issue: external Samsung monitor worked fine on Vista, but I could not stand Vista. I put Win Xp Pro on... and I cannot get any signal out through the VGA port now. The monitor works fine (still), tested with two other latptops.
My suspicion is that the nVidia driver files, possibly the .INF, may need tweaking / replacement / etc.
Any assistance appreciated.

I have an aluminum MacBook with Lion OS. I have hooked up a Samsung external HD monitor, but the image is slightly blurry.I also see a message for a second which says Analog.What to do??

I have an aluminium MacBook and have just connected an external Samsung HD monitor. The image is blurry and I cannot seem to fix it.
The MacBook display is 1280x800 but the maximum for the external monitor is much higher. Also the external monitor sometimes displays a (rapid) message implying that it's getting an Analog signal.
How can I fix this??

FWIW, reformatting a USB disk is almost never an issue, and it's quick.
Buy a cheap external USB disk (regardless of the provided Windows or OS X or other disk format) (that's larger than your internal disk by some measure) and preferably buy a disk from a vendor that offers the right to return the disk if it doesn't work, connect the disk to your MacBook, wipe the disk and reformat it with Disk Utility, perform the backup (probably also using Disk Utility from the Utilities menu, while your MacBook is booted from the installation DVD), and then commence with the OS X upgrade.

Monitor = slow performance

Hey everyone, I own a 2.5 GHz Intel Core 2 Duo, 2GB DDR2 SDRAM, 17" Macbook Pro (08) running Leopard v10.5.8
I recently purchased a 23" Samsung SyncMaster B2330 LCD monitor. Which I have connected to my Macbook Pro via DVI/HDMI cable.
I'm not sure why, but it seems that my computer is running fairly slower! A performance rate that is very noticeable in the work I do. Even small things such as browsing the internet I notice a huge difference. Now when I plugged in the monitor the only settings that were changed was obviously the Screen Resolution which changed to 1920x1080 instead of the old 1600x1200. I did not install any drivers for the Samsung monitor, I don't really think there is a need to.
Before this monitor I had a 19" or 20" Acer LCD monitor which was connected via VGA and I had no problems with performance with that monitor, everything was the same. Is it maybe because the screen resolution is higher that the performance is going down? I mean it's only a 23" monitor, not a huge flat panel 70" TV display!
Can someone please explain to me what is going on, or maybe guide me in the right steps of fixing this issue or even providing information as to what I may be doing wrong.
Thanks! Very much appreciated!

In other words some monitors just do that.

View video on external HD Monitor in PP 5.0.3

Hi, I'm new to Premiere CS5 and I've been searching for a couple of hours and can't figure out how to playback HD video to an external HD monitor within Premiere Pro 5.0.3 and my Blackmagic Design card. I can see and choose all the Blackmagic presets, view the video in Source and Program monitors in Premiere, but nothing shows up on my Samsung HD monitor. It works in FCP where I can choose from over 2 dozen HD video monitor playback options or Apple Cinema Desktop. Any guidance will be greatly appreciated.
Jim

Great suggestions. Thanks for your help. Going back and making sure those settings were in play has given me playback through the Blackmagic card to my monitor!
best,
Jim

External LCD Monitor Connection - Unacceptable Quality

Hello,
I have recently purchased a Mac, hoping that I would be able to connect to my external LCD monitor (19" Samsung SyncMaster 920NW - only VGA connection).
I have easily hooked up my monitor to my Mac. However, what I see is of unacceptable quality. When compared to Macbook display, the display on the external monitor is darker and the text looks horrible. I have played with few settings but nothing good.
I have read other threads where people complain about similar things. But, I thought Samsung's monitors would be of higher quality. Mine is a relatively cheap LCD but not this cheap
I am just willing to confirm that I am not missing anything. I simply can't believe that the display quality could be this bad. In the worst case, I will have to buy a new LCD.
Many thanks in advance.

Hello stedman1,
Thank you for your quick reply.
Unfortunately, it is not running in the Mirror mode. The display with the mirror mode was even worse! But after reading the posts in the forum, I have learned how to change it to the extended display. It is better than the mirror mode, but still not good enough.
Maybe I am making a mistake comparing the external monitor with the MacBook's monitor?? There is a huge gap between the two. It is a lot darker, and the text quality is way worse.
Someone with a similar monitor having solved this issues?
Thanks,
Guven.

Samsung Monitor for MacBook Pro

My husband just purchased a Samsung Monitor, model # 226BW for my MacBook Pro. The instructions for the monitor only refer to Windows with no mention of Mac OS X. Can this monitor be used with the MacBook Pro? My husband researched monitors that were supposed to be compatible with MacBook Pro and this one came up as one that would be. Thanks.

That is completely normal behavior. How do you want to use the monitor?
Most of what you want to adjust is in System Preferences -> Displays. If the display is on and connected, you get a separate control window on each monitor. You can control how the external display appears to connect to the laptop screen (right, left, above, below, etc.) You can also turn the display on to "mirroring" which will show the same thing on both screens.
If you want to use the external display alone, you'll have to attach a mouse and keyboard (USB or bluetooth). Then, you can close the MBP and it'll just use the external screen.
There shouldn't be any compatibility issues at all.

External Video Monitor with iMac possible.

Dear friends,
recently i have bought one imac 21.5" mid 2010 model. i am a film maker. i make TVC s, corporate docu, docu and short films. previously i worked hiring differnt post production studios but with growing volume of work i there was need for a personal edit setup. i have FC Studio 7 installed in my imav. i wanted to connect one external video monitor to facilitate the edit work flow. 1st i bought and connected a mini dp to vga adaptor and connected my 6 series samsung lcd tv with it. but the result was not satisfactory. now the lcd tv have become the second monitor and the system was working as dual monitor system. i wanted 1 video monitor as we get in pro studios. then i bought 1 mini dp to HDMI adapotor and connected it with the lcd tv throgh HDMI cable. fantastic. system took it automatically. Now i opened FCP, set a/v display to full screen, audio out to HDMI then view>external video>full frame. and u are through. now yuo can see the time line output in the LCD tv with sync audio. cheers. any better way to calibrate the second monitor?

Thanks a lot for your help.
If i consider an old model, maybe one with a DisplayPort input (late 2009 or mid 2010 iMac), is there a chance to connect the card with the DP input with a simple cable, or to verify the compatibility? The card has a DP output but many articles say that screen flickering or blue screen is the result...

Andrea

White dot (not dead pixel) on external LCD monitor.

Hi all,
I recently noticed a strange situation. I've owned a MacBook Pro 13" since October, and usually run it with an external Samsung T260 LCD monitor by MiniDP to DVI. I run the monitor at its full resolution of 1920x1200.
When I arrange the monitors so that the Samsung is on top of my MBP, there is a white dot about the size of a pixel approximately 3 inches from the left and 1/2 inch from the bottom of the screen. I thought it was a dead pixel, but when I move the external monitor to be on the left of the MBP, the white dot moves to 3 inches from the top and 1/2 inch from the right.
* The white dot does not appear when I arrange the monitors in any other configuration.
* The white dot appears when using MiniDP to VGA adapter as well.
* When I zoom using the modifer key+scroll method, the white dot grows bigger.
I've tried using the JScreenFix applet, but as I said, it doesn't look like a dead pixel.
Can anyone offer any other suggestions, that may involved poking around in the Video RAM space?
Thanks,
-Tony

Hi all,
Just returning to provide more information:
While playing around with my screen layouts, I found that the white dot is actually part of the menu bar graphic. I arranged my monitors and captured the screen to show the placement of the dot.

I hope Apple is able to fix this in the next SW update.

Ground Noise Problem Possibly Attributed to Samsung Monitor

I have a Samsung SyncMaster 730b and a 15” Apple Powerbook G4 (1.67 GHz), powered by the standard Apple 65 watt power adapter. I typically connect my Samsung 730b monitor to my Powerbook to use it as a second display connected through a DVI cable. For some reason my power adapter plugged into the Powerbook is turning itself off, which fails to charge my battery and eventually drains the computer to nothing. I am able to get the power adapter to start charging again if I unplug it from the wall and then plug it back in.
I have been troubleshooting the problem for months and have spent a lot of time researching online, including all of the pertinent Apple and Samsung support forums I can find. Apple says that the power adapter shutoff occurs because the AC adapter's over voltage protection feature senses ground noise and turns off the adapter. The company also says that it may not happen if the power adapter is plugged into an uninterruptible power supply (UPS).
I have not tried a UPS yet because it will require a significant purchase and only some users on the support forums have found the UPS to be successful at stopping the power adapter shutoffs. I have reset the PRAM, NVRAM, and PMU that Apple and individual users have suggested and I continue to have the problem. The problem persists no matter what outlets, surge protector, or combination of the two is used for the Powerbook and/or monitor. I normally have additional peripherals connected to my computer, but the problem has persisted without any devices (other than the Samsung monitor) plugged into my computer.
I have had the problem at my current apartment and my previous apartment. I have never had the problem in any other location I have used my laptop, but I have also never used my Samsung monitor in any location other than my current and past apartments. I have connected the laptop to a Westinghouse LCD television for more than a week and used that as a second monitor (to troubleshoot the problem). I have not had a problem with my power adapter while using the Westinghouse as a second monitor. I have only had the problem when my Samsung is connected to my Powerbook. The problem persists whether or not I use a VGA cable with DVI adapter or a straight DVI cable from the monitor to the laptop. The problem does not occur if the monitor is not plugged in to my laptop, regardless of whether or not it is powered on (e.g. my monitor turned on and searching for a signal that isn’t there does not cause the Powerbook to have a problem). The problem also persists whether I set the external monitor to a 60 hz refresh rate or a 75 hz refresh rate.
*To recap, the problem is not solved by:*
-Using a different monitor cable
-Using a different power outlet for the computer
-Using a different power outlet for the monitor
-Using a different power outlet for the surge protector
-Using a different surge protector for the computer
-Using a different surge protector for the monitor
-Bypassing the surge protector and plugging the computer straight into the wall
-Resetting the computer’s PRAM
-Resetting the computer’s NVRAM
-Resetting the computer’s Power Management Unit (PMU)
-Using a different refresh rate on the Samsung monitor
-Unplugging all peripherals from the computer except for the Samsung monitor
-Using the computer and monitor in a completely different apartment (on the other side of town)
*The problem is solved by:*
-Using a non-Samsung LCD TV as a second monitor
-Not using an external monitor
My troubleshooting leads me to believe that the Samsung monitor is causing a problem through its connection to the computer. I do not believe it is a problem with the monitor’s connection to the power outlets in the apartment because the problem does not occur when the monitor is powered on and unconnected to the computer. I therefore do not believe plugging the monitor and/or computer into a UPS will solve the problem.
I do not believe it is possible for the monitor to be sending electrical noise out of itself and into the apartment’s power outlets, but if it is, I have one additional troubleshooting configuration I would try.
I understand this is an elaborate description of my situation, but I hope it is helpful in showing the isolation of variables and troubleshooting actions I have followed. Have any other users encountered a similar problem? What do you believe the problem to be and what suggestions do you have for me to continue using my Samsung monitor?
Thanks in advance for your assistance.

Hey Lou and eww,
Thanks for your quick replies.
The problem started about a year ago in my previous apartment. I do not have any AC line control devices, but I don’t think my current neighbor’s connections are relevant because I had the problem in my previous apartment. My previous apartment was actually a room in a house and that is where my problem first appeared. I had the same setup there as I do in my current apartment, so I counted that as my “second location.” Eww, Are you recommending I try another?
I don’t think I mentioned this in the original post, but my problem doesn’t happen at consistent time or time intervals. It happened about five minutes ago, but that was the first time it happened since I posted on the forum about 14 hours ago. Sometimes the adapter goes off twice in an hour, sometimes it can be several hours or days before it happens.
I am using the grounded three prong cord that attaches to the white apple power block.
If I were to get a new power adapter, I’m thinking the igo juice70 or igo everywhere85. If I were to get a UPS, I’m thinking the APC UPS BE550G or BE550R. Please comment if anyone knows any specifics about these products that probably won’t help my situation. Like I said originally, I am trying to avoid purchases unless I am pretty confident they will solve my problems. I will try to borrow a friend’s power adapter soon and see if that is less sensitive.
Any additional comments or suggestions by anyone are always appreciated! Thanks!

External LCD monitors with DVI PowerBook: Banding Issues

I have a DVI PB and would like to attach an external LCD monitor. I've looked at both Samsung 20 inch and ViewSonic 19 inch versions but whenever I attach them, I get "banding" around the edges of the external monitor. Tonight, I went to CompUSA to look at the Samsung 204B 20 inch. Taking my PB with me, I hooked up and set the resolution to 1600 x 1200 and the Samsung had huge, fat black banding all around the monitor. If you don't know - banding looks like a large, black border going around the screen. The sales guy pushed some auto-set buttons (which is said always work to remove the banding) but it didn't fix the issue. Any suggestions? Is there some secret that I'm not aware of on how to attach and use an external LCD monitor with the PB? One note: I did set the resolution down to 1280 x 1024, which worked fine to remove the banding but it monitor looked horrible. Not the best resolution for a large monitor.
Thanks,
B. Rose
TiBook 800 & iBook SE Mac OS X (10.4.6)

Hi, Bill. I can't speak to whatever happened with the Viewsonic monitor, since you didn't tell us about that, but it sounds as though the Samsung was in display mirroring mode rather than extended-desktop mode. The F7 key on your Powerbook's keyboard toggles an external monitor between the two modes. In mirror mode, the external monitor displays exactly the same thing as the built-in display. In extended-desktop mode, it functions as a separate portion of your desktop, and you can drag things (windows, icons) from one monitor onto the other. If you're going to use both displays, extended-desktop mode is probably what you'll want: why keep two copies of the same thing in front of you?
In mirrored mode, the fact that your Powerbook's display has a maximum resolution of 1280 x 854 means that only 1280 x 854 pixels of the external monitor can be used — leaving wide black borders of untapped pixels around the copy of your PB's display that's centered on the external monitor. In extended-desktop mode, the external display's native resolution of 1600 x 1200 can all be used, provided that your 32MB of VRAM is sufficient to drive the total of (1280 x 854) + (1600 x 1200) = 3,013,120 pixels, at the bit depth you've selected. (You might have to use the extended-desktop mode in Thousands of colors, rather than Millions.)
Another issue that comes into play with display mirroring is that the 4:3 aspect ratio of the 1600 x 1200 Samsung is different from the 3:2 aspect ratio of the Powerbook's display. If you set the Samsung's resolution to 1280 x 1024 to match the pixel width of the PB display, the top and bottom of the Samsung will be black bands, because the PB isn't manufacturing any pixels to fill those bands. And it will be blurry, because the Samsung has to interpolate to make 1600 pixels look (sort of) like 1280 pixels. Unlike a CRT display, the actual number of pixels in an LCD is fixed. When you change resolution settings on an LCD from its native (maximum) resolution to anything less, the image is always blurred. Only the native resolution can be really sharp.
