TFT LCD Samsung SyncMaster 193p Display blacks off

in the past few months my Samsung LCD c. 2004 has begun to sporadically
black out/shut down on its own. the screen goes black and the small blue power light shuts off.
just this week it has gotten especially frequent. today when i was working it flashed off/black 5 or 6 times.
to get the display up again my patchwork MOA has been to do the shut-down, un-plug, re-start, re-plug, or any combo of such things.
usually it takes several versions of any combo of these actions to produce results, and i will then get a couple hours of work in before the monitor goes black again.
i connect to the G5 with the DVI adapter.
and actually right now i have hooked the LCD up to my old iBook to check out its behavior here, and it has done the same thing...blacked off.
so ummmm my question is whats the deal? is it a problem with the power cord/source? or with the LCD? and how do i fix it....
thank you.

hi - thanks for the reply. the 193P is a great monitor! great looking and very functional, i get compliments on this monitor all the time and until now i have never had problems with it. it did have a 3 year warranty as well, of course that has expired so if my black screen problems continue i will do like you have suggested and look on ebay for new power supply.
one other thing i noticed tho was that the DVI connection seems to have loosened up somehow, i mean on the DVI port on back of the monitor - when i unscrewed the DVI cord to detach, with it came the little bolt that is supposed to stay ON the monitor. so i then had to tighten by hand that little bit back on to the monitor. but that connection being kind of loose would not be causing the power light to go out and screen to go black...would it?

Samsung SyncMaster 215TW display goes black for 2-3 seconds on DVI

My SyncMaster 215TW goes black (blinks off?) for 2-3 seconds while connected to my PowerBook by DVI. After trying to get help from Samsung's support site (lot's of the widgets seem to be broken), I found a page ( http://erms.samsungusa.com/customer/sea/jsp/faqs/faqsview.jsp?PG_ID=1&AT_ID=15272&PROD_SUB_ID=28&PRODID=-1 ) that suggests such behavior is a result of a cable or video card. This behavior happens at most, only once per session. I'm not sure if this is a problem, and if so, if it's the display or the PowerBook's Nvidia chipset. Has anybody had any problems like this?
Thanks.

Hi rossmatt06,
If you are having intermittent issues with the external displays connected to your MacBook Pro, you may find the following article helpful. In particular, if at all possible I would test with different adapters to try to rule out an incompatibility.

Samsung SyncMaster 204b goes on and off

I have a 20" Samsung SyncMaster 204b flat panel that I purchased not two weeks ago. I have it connected to my PowerMac G5 dual 1.8Ghz through the digital connection on the graphics adapter.
Every now and then it just goes black and then comes back on. It's off for about a second, maybe two, before coming back on. Sometimes it happens when I'm switching pages using Safari. From what I can tell it usually happens when I'm doing something. In other words, when I'm not actively using the computer it doesn't ever seem to turn off/on.
Has anyone else seen this? Does anyone have any suggestions?
Thanks,
Tom
Dual 1.8 PowerMac Mac OS X (10.4.7) 2 GB RAM

I've got the same Samsung display as you, but I'm running it on a brand new $599 Mac Mini Core Duo bumped up to a gig of RAM. The computer just arrived yesterday and I've got the exact problem you describe. Unfortunately both the Mac and the Samsung are brand new so it's impossible to isolate the problem (I lack a second desktop or display), but I'm willing to bet the Mac is to blame.
The infuriating thing about the problem is that 98 percent of the time the computer and display work great. There's no predicting when the problem will strike. I've tightened my DVI cord connections so I know that's not the issue.
My problem actually seems worse than yours, since the problem often comes in waves with the monitor repeatedly switching off and on for a second or two at a time -- and then finally often blanking out entirely. Once the problem begins, I'm usually hosed --- the shutoffs get more frequent and ultimately keep coming every few seconds and then they start lasting for increasing periods until the display doesn't come back on.
Interestingly, on two occasions already, I've sat back and watched a 40 minute TV show on DVD without incident, but the moment I head back into the finder the problem begins.
The good news is I've found a fix...a fix for my problem anyway, which I think is just a severe version of what you're experiencing. On two occasions when the monitor wouldn't come back on, I hit the power button to put the Mac to sleep. After waiting just a second or two I hit the power button again to awaken the Mac, and the monitor again functioned perfectly. A few seconds asleep was all it took. You'd think there had never been a problem.
I've been doing some reading on these forums and elsewhere and this post seems of interest:
http://discussions.apple.com/thread.jspa?threadID=634474
It describes a "dancing pixels" phenomenon that neither you nor I have experienced (if you search for "dancing pixels" you'll find plenty of posts). BSteely's response to the above post suggests a possible culprit...the possibility that our blank screens are the culmination of our monitors going out of phase with the computer's timing. Some people have said that lowering the hertz setting for your monitor through DisplayConfigX or SwitchRes X can solve the dancing pixel problem, so perhaps that can solve our problems too. But I'm unwilling to do this for now, since I don't want to degrade my screen's otherwise amazing display quality.
Right now I'm in the awful position of having a brand new computer and display with an intermittent problem that I don't know how to resolve. But discovering that it can be temporarily corrected by putting the system to sleep is at least a help.

Samsung SyncMaster 2243 Shows Only Black

I've just purchased a Samsung SyncMaster 2243 monitor and changed its resolution. When rebooting my Mac the monitor shows only black with an alert exactly saying: 'Non optimum mode - Optimum mode 1920x1080 60Hz'.
The point is that I have no chance to go and change the resolution, because the monitor won't show other than black. I tried to restart from the system DVD pressing the C key on restart but with still the same result.
Don't really know what else to do. Can anyone eventually help me from out there?
By the way, I must say (and this is the strange part of all) that the first three or four times I switched my Mac on, after the advice the monitor showed, I could see my desktop and operate normally.
Thank you in advance
Giovanni

I would connect it to another monitor that I knew will work, once at the DT I would go to system preferences and set the display to a setting I know will work, say 1024x768, shut down my mac, connect the samsung and start. If you have a graphics card that has duel video ports and connect both up and set the video settings that way.
Does the samsung have a menu that allows monitor settings that can be changed?

Photoshop and monitor profile (Samsung SyncMaster 244T with EyeOne Display 2)

I've just calibrated my Samsung SyncMaster 244T with EyeOne Display 2 and
created a monitor profile. Should I use it as the Photoshop working color
space now?
Thanks.

So my monitor profile is just for the OS, and photoshop should use either sRGB or Adobe RGB, or whatever color space specific to the output destination. So, say, if I plan to edit some files for a video slide show that I'm making using ProShow Producer I should edit those files in one of the NTSC color spaces and save that profile with the files. I used to just leave them in sRGB and saw some weird color results watching those slide shows on TV. Thanks a lot for your info, Christopher. <[email protected]> wrote in message news:[email protected].. > No. Your working space should usually be a color space with well-behaved > characteristics such as black and white points being equal RGB values, as > well as the values for grays.

Mini Display Port to VGA cable can't detect Samsung SyncMaster 2693HM.

Just conected a Samsung SyncMaster 2693 to my Mac Mini (2.5 CPU mid 2011) with an Apple Mini DisplayPort to VGA adaptor it only sees the monitor as a VGA display and is limited to 1920x1081. I was using the same adaptor with an older Mac Mini (mid 2009) and had no problems getting the full 1920x1200 resolution. I've resarted and reinserted the cables, with no joy. Any ideas?

Looking into my problem more deeply it seems that the adaptor is a fault
As stated by BSteely @ this thread https://discussions.apple.com/message/9447077#9447077 it seems that the 1600 x 1200 @ 85Hz is most likely beyond the capabilities of the DAC onboard the adaptor.
Apple does make reference to this slightly in this FAQ http://support.apple.com/kb/HT3382 stating "The resolution available with the Apple Mini DisplayPort to VGA Adapter is 1920 x 1200. VGA displays that use higher refresh rates (such as 85 Hz) at resolutions of 1600 x 1200 or greater may not generate video properly until you lower the refresh rate."
Begin Rant: "May" As far as my understanding goes the chip inside this adaptor is either designed and the firmware is progamed to support 1600 x 1200 at 85 Hz or it is not. No "May" about it.
The solution is as simple a providing a list of resolutions and refresh rates supported by the adaptor in some sort of "Technical Specifications" not simply the description provided by the overview in the apple store which makes no mention of any limitation other that the requirement of a display port.

Problem (ugly display) with Samsung syncmaster 2243

Hello
I just plug my Samsung Syncmaster 2243BW on the mac mini (DVI). The resolution set is the good one : 1680x1050 @ 60hz, but the display isn' t clear, accurate, especially with the fonts.
any ideas
thanks in advance

Without knowing exactly what it is you see and object to, I will say that a 22" monitor with 1680 x 1050 resolution is at the low end of the scale among most monitors on the market in terms of density of pixels on the screen. If you consider one square centimeter of area on your 22" monitor, it will have approximately 1250 pixels within that area. Then consider that a 17" MacBook Pro will have 2750 pixels within that same area of one square centimeter.
Obviously text will look a lot more clear when there is a pixel density of more than double on one display compared to another. Again, I am not sure if this is the underlying reason for your complaint about your new monitor, but it's something to consider.
Samsung also make a 2343 monitor, and even though it is only one inch larger in size, it is quite a bit higher in resolution. You might be happier with that.

3rd Party Display Resolution Issue - Mid 2011 iMac 27inch Mavericks- iMac wont allow max resolution of Samsung SyncMaster SA850

Hi Guys,
I just updated my 27 inch iMac to Mavericks and can't get my third party 27inch Samsung screen to run at maximum resolution. Even when using the "Alt" Click and select Scale shortcut I cant display the 2560 x 1440 resolution the screen is capable of.
I've called apple support and they couldn't rectify the issue nor could samsung. I've even tried the monitor in another iMac updated to mavericks and have the same issue.
Im connecting using a mini display port to DVI cable through my thunderbolt port.
My machine is Mid 2011 27inch iMac 3.1ghz core i5 with AMD Radeon HD graphics card upgraded to Mavericks
Monitor is brand new 27 Samsung SyncMaster SA850. I was able to get it to work at max resolution on a Windows 7 PC.
Any help would be appreciated. Thinking of returning the screen, hopefully Samsung will take it back.

The standard > Mini DisplayPort to DVI Adapter only supports 24" monitor resolutions up to 1920 x 1200.
For a larger monitor you need either a > Mini DisplayPort to Dual-Link DVI Adapter
or perhaps a simple Mini DisplayPort to DisplayPort Cable if your monitor supports DisplayPort input.

MMacBook Pro (13-inch, Mid 2010) switches on but internal display remains off/black .There is no start-up sound and the fan starts off normal but after about Five minutes begins to run even faster

Hi ,
My MacBook Pro (13-inch, Mid 2010) switches on but internal display remains off/black .There is no start-up sound and the fan starts off normal but after about Five minutes begins to run even faster as if the machine is running a heavy load.It displayed a question mark some time back then a friend borrwed it ,he flashed the system and put windows 7.Then a few days pasted and now it wont display as stated.I have tried to Reset SMC and the Command + P + R + Power but still no response.Please assist?
Regrads Josh

I think your "friend" caused a problem (or two).
I do not know what "flashed the system" means......
Based on what was done, I would probably erase the HD and restore the system from a backup before the software changes were made.

Lenovo T60 - External Monitor Samsung SyncMaster 213T 1600X1200 problem

Hi All,
I have my monitor (Samsung SyncMaster 213T) hooked up as an extended desktop to my T60 (directly, no docking station). I'd like to use my monitor at its full resolution of 1600X1200. (It works in this resolution fine with my desktop and my other laptop a sony Vaio). When I set the monitor to 1600X1200, the screen is displayed compressed with black bars on either side of the monitor.I tried updating with the latest driver for the monitor but still the same results.I'm copy-pasting the information below from the Intel graphics settings tool below. Any help in this regard would be greatly appreciated.

Connecting a Samsung Syncmaster 205 BW widescreen to a Powerbook G4 alumini

synchronizing a Samsung widescreen TFT BW 205 with a Powerbook G4
Posted: May 20, 2007 2:42 AM
Click to reply to this topic Reply email Email
I recently bought a Samsung Syncmaster BW 205 (widescreen) to work on my Powerbook G4. Problem is I can not get it right (my apple screen is 1280x840 and the Samsung is 1650x1080 (or something like that). The Powerbook recognizes the Syncmaster but somehow it does not match. How do I solve this problem?

Possibly your PowerBook is running in mirror mode. This means both screens will be set to 1280 x 854. Try turning mirror mode off in Display Preferences and see if that helps.

MacMini looks terrible with Samsung SyncMaster 225BW

I have the latest Mac working with a Samsung SyncMaster 225 monitor, and the font aliasing look terrible! Is there anything I can do about this? I have gone through the colour calibration and it is slightly improved, but it still looks pretty poor.
I have connected this monitor to a PC and the font display looks good, except for Apple's webpages (such as these discussion forums)! What fonts are used here? And why do these look so poor on this 22" 1680x1050 DVI connected TFT monitor?
Any clue would be appreciated?

Thanks for the reply. I think it is half and half, the problem is both Apple and the Samsung. I believe the graphics adapter (Intel GMA 950) in the MacMini is pretty poor and what you said about Apple's font smoothing... and I think the actual Samsung panel is somehow not good with this adapter.
I tried the MacMini on an NEC 21" and it looked better, and I also tried it on a BenQ 24" and this was pretty good. I also have a iMac 24" and whatever panel they use in that, the fonts, etc looks pretty **** good!
So there must be something going on with the Samsung 225BW and the Mini itself! (Although, to be honest, my NEC 1770NX 17" LCD monitor is not giving that good a display at the moment!)
Is there a way of updating the driver for this Samsung (or this NEC 1770NX) monitor?! Are we all stuck with whatever driver the Mac uses when it detects the display?

Traditional TFT LCD of the N900 and the new SLCD !

Can anyone here explain me is S-LCD the next generation of the TFT LCD does it offer a dramatic improvement in display ( I am not really looking out for a very technical explanation just need to know from a user perspective) is it great fun watching in SLCD compared to the traditional TFT LCD display that the N900 has. if yes, How much the difference between the TFT LCD of the N900 and SLCD would be ?

@CP...
such a nice post...needs to be said again without needing to re-finger it in! +1 m8..
cpitchford wrote:I meant it's not the right place to ask as there are other forums that seem to specialise in talking about LCD panels
So I really dont know what you mean when you say the resolution is the same between OLED and SLCD...It is not the same
Huh??
OLED and SLCD do not define resolution.. you're wrong for thinking that.. They are types of displays.. OLED is not fixed to 800x480, SLCD is not fixed to 960x640.. Its like saying diesel engines are 2liter where as petrol engines are 1.5....
OK.. The HTC Desire (and google Nexus one) originally shipped with OLED displays..
Due to shortages of OLED panels, HTC decided to change the display type to the more commonly available LCD.. Now HTC Desires are LCD..
However..
The resolution is exactly the same.. they are both still 800x480.. The type of screen does NOT dictate the resolution of the screen..
You could have a crud low resoltion 640x360 OLED screen on the Nokia N8, and a high res 800x480 LCD screen on the N900.. both are 3.5" screens!
As for the difference in visual quality of OLED and LCD:
OLED screens are tiny light bulbs.. each pixel produces its own light (actually multiple red, green blue lights per pixel)
LCD, however works using filters.. There is a white light behind the screen, and the LCD lets some of the light through coloured "holes".. That is the MAIN difference between LCD and OLED..
All OLED displays work like this and all LCD displays work like this..
So, because it is easier to make a filter of a certain colour, LCD screens can often produce more realistic colours..
OLED displays however, have the ability to go completely dark.. Look a black screen on a LCD display (like your phone) it still glows.. thats because the LCD cannot filter out ALL of the white back light.. it just filters out most..
OLEDs, however, when they are black they are OFF meaning they produce ZERO light!!
LCDs range from blight to dim.. whereas OLED range from even brighter to totally black..
This is called the contrast ratio..
It also might mean OLED displays seem "saturated" the colours are too vibrant..
Now, that's OLED v LCD
Going back to your question in your second post..
The Desire PS IPS LCD display (that's the S-LCD display if you want a brand name) is technically a lower definition because the pixels are larger when compared to the N900..
The colour reproduction (how accurate the colours are) and the contrast ratios however will be BETTER than the N900 because the Desire can display 16Million colours rather than 65thousand.. and the LCD technology is a generation newer than that used in the N900...
The N900 screen, although high resolution for its size, is fairly old tech..

I just bought Mac Book pro; trying to hook up dual monitor with Samsung syncmaster 2033 but no signal; I am using dvi to hdmi converter. Please assist.

I just purchased a Macbook Pro but unable to set up dual display with samsung syncmaster 2033 via DVI to HDMI port.
Thank you in advance for help.

There has been quite a lot of discussion here about driving twin displays with the mini, and more recently about the potential for USB video adapters to facilitate this, particularly in the light of several vendors claiming they have suitable MacOS devices and drivers 'almost ready'.
The DisplayLink solution seems to be the one most suggested as viable, though it's a pity they have not yet been able to move their drivers from beta - I suspect that puts a few people off. It's therefore good to hear of a real-world experience that should help others decide whether or not to go this route!

MacMini mid-2011/ Yosemite w Samsung Syncmaster monitor

Hello all.
I have been happily working with my MacMini mid-2011 (2.3Ghz Intel Core i5, 8GB RAM) with a Samsung Syncmaster B2440 HDMI-connected to it for a long time.
Since the upgrade to Mavericks and later to Yosemite, the following problem occurs: when switching the monitor off, and later switching it back on, no video signal is sent to the monitor, which remains blank and tries to switch through all its different inputs. Unplugging the hdmi cable and plugging it back in also gives no joy. It looks like the whole video output services are switch off at OS level or something.
The only thing I can do to get the monitor on, oddly enough, is to connect to the mac mini through a remote desktop from another device, and switching the display to my AppleTV. This action does switch also the Samsung monitor back on.
So I then thought, great, I will create myself an apple script and a workflow associated to this AirPlay monitor switch and associate it to a keyboard shortcut, but this does not appear to work either (no, the shortcut is not in conflict with any other global shortcut).
Any help will be much appreciated.
Thanks
Joe

Hi lllass.
When I tried that it appeared to work, but after some days it started doing it again. I am really puzzled by this.
