Monitor red problem

I have a MacPro 2011 model connected to a Samsung 37" HDTV(2009 model) via a Apple DVI to VGA adapter and a belkin high quality VGA cable from this to TV. I use switchres in osx to make a custom resolution to get the 1920x1080 res.
I did have a Samsung 37" (2007~) model connected same setup and all was good until it died. My 2009 Samsung TV tho has a wired red problem, it's like overblown, red text is slightly blurry. All other colours are fine.
It's the same in osx and in windows xp(running off boot camp)
I've tried the monitor on a old advent pc with a VGA output and its fine.
Anyone know what's wrong?

Thanks
I live in the UK, would something like this work?

Wierd monitor compatibility problem

Hi all,
Got a wierd monitor compatibility problem. G3 works fine on a sony 21" CRT.
Connected it to a Daytec 15" CRT which works fine with a windows 98 PC.
With the G3 I get the apple and the spinning up logo then the screen just goes blank.
Is this monitor PC only or something? It is an old monitor but I thought any monitor should work
if the vga connector fits?

So you are using this directly plugged into the stock Display card in a Blue & White G3 with NO adapter?
The Mac is probably still set for a higher resolution that the SONY can do, and has not noticed the display has changed.
Video pros says that Video can be plugged and unplugged all day long with no bad effects. If your old display is still around, try setting it to 640 by 480, save changes, and swap the other one in "live" at that resolution.
Other tricks:
Reset the PRAM. This will send you back to a default setting while booting up, but may change when the system becomes active.
Boot from a CD. This ignores the settings on your Hard drive, and boots to a very simple resolution like 640 by 480 to ensure that Most Macs can start up with it.

Monitor hardware problem

I've got a DV2721nr, and the monitor seems a little loose for the past six months or so, and in the past week its starting to glitch. Today it started SERIOUSLY glitching whenever I turn it on, during the login screen (so far it only does this during the login screen) it looks like its skipping, bouncing around a million times, then looks like the color is whiting out.
anyone else ever encounter this problem? I think tis a hardware issue and not software cause if I apply pressure to the screen, it affects the glitching and sometimes (if I'm really lucky) fix it completely so I can login.I dont know what is wrong with it, so any help will be greatly appreciated.

There is only one combination of Red, Green, Blue, HSync, and VSync that will run a high quality monitor.
When you change the switches on your adapter, most of what you are doing is changing the wiring of pins 4, 7, and 10. These pins, and their connections with wires and diodes, are read by the Mac at startup to tell what family of genuine Apple displays is attached. (The code is like a promise that a certain display is being used.)
The Mac uses this information, read at startup, to decide what resolutions and refresh rate are valid for the display you said is attached. No others are provided by your Mac, because they might damage your display.
You have been focusing on the display as the likely source of the problem. I doubt that the display is the problem. The display is a slave. It takes the rows of dots given by the computer and attempts to paint them on the screen, and adjusts the frequency to match what the computer is sending if it can, and otherwise goes blank.
If you take that same "adapter" and cable, and connect it to the Apple display, I expect you will get similar good results.

Monitor window problems in CS4?

I just upgraded to CS4 from an older version. I have Premiere Pro 4.2.1. I'm using it on a Windows XP machine.
The monitor window is not behaving at all as expected.
I imported a Photoshop file to use as a still for a few seconds. The thumbnail in the upper left corner of the project window looks fine, but the colors in the monitor window are really bizarre. For example, the white background of the Photoshop file is displayed in the monitor window as a horrid salmon color. The places that should be red in the Photoshop file display in the monitor window as royal blue. I tried exporitng the sequence to an AVI file, and the colors came out fine in the AVI file. So the problem appears to be confined to the behavior of the monitor window.
When I move the slider back and forth in the timeline window, I would expect the monitor window to display whichever frame I'm passing over. But it doesn't. It'll update the view (with incorrect colors) when I pass the slider in the Timeline window over a still, but if I pass the slider over a clip, it just preserves the display of the most-recently-displayed still.
I have also noticed that there is no longer a help file local on my hard disk - when I click o nthe "help" choice from the menu bar, and then pick "Adobe Premier Pro Help", instead of accessing a local help file, it goes out to Adobe's web site. This was EXTREMELY annoying when I was trying to use this stuff on an airplane without web access! How am I supposed to get help when I don't have Internet access?????
Can anybody point me in the right direction to solve these problems?

The links in this ARTICLE might prove useful. Most often, this is caused by either an outdated video driver, or perhaps a setting for Hardware Acceleration, OpenGL, or similar.
Also, as Harm mentions, make sure that your PSD is RGB 8-bit, and is also appropriately Scaled in PS to near the Frame Size of the Project. Usually, CMYK, or 16-bit PSD's will yield error messages.
Good luck,
Hunt

Nokia 5800 express music monitor "screen" problem

hi all,
i've a nokia 5800 device and i've faced a very serious problem:
when i lock the phone and unlock it the monitor or screen dont appear as previous normally, instead of that shaked colored lines appear, so i can't see who is calling. But the touch is working normally so i can play music or answer calls but without knowing who is calling.
if i switch the phone off then switch it on i see the the screen normally, and when it locked then unlocked the same problem appears again.
i've tried to solve the problem by formatting the device but it is no use
the same problem faced my frien
i don't know what to do, please give me a hand......
Solved!
Go to Solution.

I've been having a very similar problem with my nokia 5800 expressmusic.
it started off like yours but then the screen went fully black.
the green, white and red buttons at the bottom work so does the small touch button at the top right.. those lights always come on when i unlock the phone so they're fine.
I know that my phone is still working because i was randomly touching the screen when the phone was unlocked (even though i cannot see anything on it) and i ended up calling somebody. my only problem is that i cannot see the screen at all!!
i've tired turning my phone off, taking out sim and memory cards, putting different sims in and charging it.
nothing works!!
is there anything i can do?
can anybody help me with this?
or is my phone just past its 'use by' date?
please, please help me!
thanks

Mini DVI to external monitor (VGA) problem/firmware update does nothing

Hi,
Four months ago I bought a new white 13-inch Macbook (2006 model I believe) along with a handy mini-DVI - VGA adapter. I used a Hanns-G HU196D external monitor which worked fine for a couple of months but then stopped, and had the same problem with a (much cheaper) 'LiteView' monitor. I find it bizarre how they work absolutely fine and then stop, with no damage to the adapter, cable or ports. I've since bought a new adapter and cables + trying out a different monitor and still the same problem...
I've installed a firmware update that describes the exact symptoms, but it's done nothing. Can anyone help me resolve my issue?? It's still under warranty so is it an unusual problem that'll need to be fixed by Apple?
Thanks

Are you using the mini DVI to DVI followed by a DVI to VGA adapter? That may not work if the mini DVI to DVI adapter does not pass analog video. If that is the case, you need the mini DVI to VGA adapter:

G5 DVI to VGA Dell Monitor Connection problems, need help!!!!!!!!!!!!!!!!!!

hello,
I'm running two dell monitors both of which were connected via DVI to my g5 quad dual dvi. My tv broke and I'm using one of my monitors to connect the cable boxes HDMI input to the dells DVI input, it works great.
My problem is that i still want to run two monitors from my mac and still be able to switch channel sources from the Dells source button allowing me to switch from TV to Mac. Since I took up the dvi port on one of my monitors to connect to the cable box via HDMI, I have a free DVI cable. I purchased a tiny converter that allowed to change one end of the free DVI cable to VGA. I used this method to connect the cable to my g5's dvi port and the configured end to the VGA port on the monitor with no luck.
The Dell monitor does not pick up any signal and just goes to sleep as if my computer does not exist. The TV works fine and I'm able to switch sources. Please note that I'm not using the DVI-VGA adaptor that came with my g5 and don't know if this would make a difference. If it does, how do i set this up because this adaptor is like 5 inches long.
Does the adaptors DVI end need to be connected to the back of the g5 or does the VGA end need to be connected to the monitor or does it not matter. I need a longer dvi-vga cable as well, do they make them. This all depends if the problem actually is that that I'm not using the DVI-VGA cable that came with my mac to connect to the monitor in the first place.
Can anyone help me out here. I'm using the Dell 2208WFP Ultra Sharp.

Bad adapter?
The G5 ports are DVI-I. Any good DVI-I to VGA adapter should be fine.

After OSX.4.11 update external monitor unresponsive+problems w/sleep etc

I've read some of the recent display problems. Here is my problem and what I've tried, my problem just started 6 hrs ago. I updated to OSX.4.11 a few days ago - eveything worked fine, yesterday I reinstalled epson printer driver as it was crashing and also yesterday I worked for several hours in iMovie 08. Nothing else unusual. This is STRANGE!
Today went to wake my MBP, 2.4 GHZ, 4GB ram, Cinema display 20", wireless keyboard/mouse up from sleep to check mail. Cinema display flickered and then changed to dark blue solid - and unresponsive. Couldn't get external display to function. Never had any problems with it. Tried to restart everything, unplug all cords, etc. Everything started up I got the log in password screen on my external cinema display - typed in my password - then saw my desktop photo for a second and the cinema display flickered to dark blue again and wouldn't change. It was unable to mount the desktop.
I went to my MPB while still connected got the screen on the MBP and saw the desktop but there were sort of black lines through the names of my folder files on my desktop. I then disconnected the cinema display, restarted just the MBP and the screen (of the MBP) that mounted was perfectly normal - no black lines through file folder names.
Then I tried various things. I assumed my cinema display was broken (almost 3 years old). But then I hooked my MBP up to an old 20" cinema display (they kind with 4:5 ratio and plastic all around), I think it uses some kind of converter to the DVI port anyway my MPB worked with that old display fine, desktop fine, but it would not stay asleep - no matter what I tried. I've never had that problem ever before.
Then I took the "newer" 3 year old cinema display (aluminum one) that I use all the time I I suspected was busted and hooked it up to my old Powerbook G4. And it mounted the desktop and worked fine!! The G4 just got updated to 10.4.11. Interesting thing is though when I closed the lid which usually made the G4 PB sleep it shut it down instead of making it sleep. Very odd.
Then I ran down to Apple store and bought new version of Disk Warrior and ran it on my MBP. I've never had anything Disk Warrior couldn't fix. It rebuilt my directory. I then hooked the MBP back up to the cinema display (aluminum) and the same thing happened I got my log in screen after startup, logged in password saw the photo desktop for a second then the cinema display went back to a dark blue screen that was unresponsive. I then ran Disk Warrior again with the cinema display attached to see what would happen. Disk Warrior mounted and I saw the whole process on the cinema display. The cinema display will mount disk warrior but it will not mount the MBP desktop as of 6 hours ago.
I then read these recent posts and tried a "safe" boot. I got my MBP desktop on the cinema display (aluminum) but as soon as I clicked on system prefs the cinema display went to dark blue unresponsive screen.
But the same cinema display (aluminum) works fine with the Powerbook G4 except for some issue with sleep
And the MBP works with an old plastic cinema display except again, it won't stay asleep.
But the MBP and the aluminum cinema display that I've been using together for my photo/video editing for 4 months straight now and I've never had any problems with - they won't work together as of 6 hours ago. That is when I get the dark blue unresponsive screen on the cinema display (aluminum).
Upshot is:
1) Something is up with sleep mode and the OS X.4.11 update on 2 different machines (G4 PB and MBP)
2) Something is affecting the way both the MBP and the Powerbook react with both my cinema displays. The MBP and the 20" aluminum Cinema display are the ones I need to work with and the ones that as of 6 hours ago just lock up in cinema display dark blue screen (almost black but not quite).
Is this a problem with sleep, startup or DVI output and OS X.4.11?
What can I do about it? I need to use my 20" aluminum cinema display it is clearly the better one of my 2 cinema displays. And even if I switch to my 20" older plastic apple cinema display the computer won't stay asleep any longer?
Please, Please I need some help.
Also since this is happening on 2 separate machines and 2 separate monitors there is something odd going on.
Apple tech people, is there a major problem with .11 and sleep and external displays?
Sincere Thanks, Carol
PS Note, I tried all this numerous times with both bluetooth and regular wired keyboards/mice along with MBP and PB keypads.

Sorry please forgive me, I'm so exhausted I posted this in MacBook instead of MacBook Pro, I'll try to move it but if I can't I'll try to copy it and post in MacBook Pro, regardless I think there is a problem with the .11 update.
Thanks, C

Dual Monitor Startup Problem on MacPro - Solved

I have a model 53135LL/A = mid 2010 MacPro with 8 cores, DUAL monitor cards and monitors, 24GB memory, running Lion 10.7.3. It is important to note that I am also using the Apple bluetooth Magic Mouse and the smaller, bluetooth keyboard (no numeric keypad). This unit was supplied with Lion in December 2011 and has had a startup problem from the beginning as follows:
1 - when starting from a cold start the dual monitor positions are reversed from the correct position
2 - additionally the USB and firewire connected devices (e.g. Wacom tablet, 2 card readers) do not function properly.
The workaround for me has been to start the system, wait for the logon screen, then click restart. Upon restart everything comes up and functions correctly.
Specifics on my setup and starting problems:
1 - My main monitor (Monitor #2) is a large gamut monitor that is located to the right. This monitor is connected to card slot 1 as that is the faster card slot (pcx16). The second monitor (Monitor #1) is an ordinary unit and connected to card slot 2 (pcx4). The monitors are set up as an extended desktop.
2. The Wacom tablet (Intuous 3 wide) is connected to USB port on rear of machine. CF card reader by Delkin is connected to Firewire on rear of machine, and an SD card reader is connected to USB on the rear of the machine.
3. My dock is positioned on the left side of the left monitor. The menu bar is along the top of the left monitor, and all desktop icons are on the left monitor. The right monitor has no items on it.
On a typical cold start, as mentioned above, the apple logo appears on the right and then the logon screen appears on the right.
If I proceed to logon at that point, all the desktop items move to the right monitor and the computer thinks the positions are reversed. In other words, it behaves as though the right monitor (#2) is on the left of the desktop and left monitor (#1) is on the right.
Additionally, the Wacom tablet using either pen or mouse does not map over the full desktop range. If I use either card reader and then eject the card, no further card insertions will be recognized.
To fix this, I simply restart the machine thru the apple menu and everything comes up correctly.
I had discovered, that instead of completing the logon on a bad cold start, I could simply restart from the logon screen and all would work correctly.
On occasion, the logon screen would come up on the left monitor (as it should do) and in that case, if I log on all works correctly.
I have worked with Apple support on the phone, clearing setup ram etc. Have had the unit in to Apple store for hardware check, all OK. Next suggestion was reload OS and start over - no thanks.
SO - Here is the latest.
If I turn off my keyboard and mouse before starting the machine, then wait for the logon screen to appear - It starts correctly, with the logon screen on the left. I can then turn on my keyboard and mouse and all works as it should.
Bottom line - there appears to be a startup issue with Bluetooth devices from a cold start. Note that once the machine has been used for a bit, I can turn it off for short periods of time (e.g. 30 minutes) and it will start correctly even with the mouse and keyboard turned on.

That's how dwm behaves. I believe dwm's multihead support is rather lackluster out of the box. You might want to check out some of the patches they have, and ask around in the dwm hackers thread.
I currently have dwm simply draw status on all monitors, but I'm investigating separate status bars per monitor. We'll see where that takes me. Dwm is a tinker's WM!

MONITOR SCREEN PROBLEMS - has anyone else had this ? HELP ..

Friends,
I am going nuts ( no don't answer that one ! ).
Recently ( possibly after the 10.5.2 graphics update - I can't exactly recall ) my LG flat screen monitor has started to look like a grainy 60's acid art house experiment !!
It is subtle but most disconcerting as I use my beloved G5 every day with Logic P8.
I have tried changing settings - calibration the lot... but still it looks strangely weird - like a TV that is not quite tuned in.
Gradients and shaded areas have weird lines instead of fine tones and artifacts appear around type and lines where was once beautiful and clear graphics.
When I first bought the LG 204WT 20" monitor 5 months ago it was fine !.
I have been using the recommended DVI output and tried different cables and the alternative input - the effect is still there but not quite as bad when using connector to RGB input.
The shaded areas in finder and Logic are almost transparent and grainy with a light blue / pink halo like effect around windows and graphic boxes.
I *don't know how to explain it really but I do hope someone out there may have some answers or at least have an inkling of what I'm trying to describe..*
As if I couldn't make matters worse I did an archive and install to roll back to 10.5.1 early hours of this morning - this didn;'t cure the problem and I lost the use of some music plug -ins and authorizations in the bargain.. Maybe it is time to call it a day and take a long break.
Really I should get a pen and paper and sit with my guitar an a darkened room for a few days.
I called the Mac shop where it was purchased then LG but with no help, advice or offers to replace it.
I guess the monitor basically works but this strange behaviour is arguably quite subtle and may not be considered 'serious' by most people !
*In the meantime if any of you lovely people could take my situation seriously and offer any practical advise I would be most appreciative.*
Many thanks - not quite lost it yet - Paul

Hi Pancenter,
Many thanks for taking time to message.
The resoloution is set as it should be and millions of colours is selected etc.
The screen has had several contrast / brightness adjustments and a factory reset with no improvement.
Also someone suggested the screen zoom might be on but this is all set as normal.
I have an imac which works fine and the difference is quite noticable - on the G5 w/ LG screen there are light blue and pink 'halo's ' around gray areas, graphics have strange patchy dots like a screen print and as I am looking and typing into this forum the gradient shaded area that says 'Apple Discussions' has very poor quality shading with horizontal blue lines !
I've also tested the cables and made sure there are no interferences - this is really weird...
I will try another monitor when I get chance - thanks again.
Paul

Recent Windows 7 update causing monitor sleep problems/Windows loop in some HP desktops?

After perusing this forum, I wonder if there was a recent Windows 7 update that has been causing problems for some HP desktops and displays. My office has a 3500 Microtower desktop running Windows 7 Pro. While Windows 7 Pro is running and in use (as in, not prompted by any user-set power management option), the dual HP displays (via DVI split to VGA) will enter sleep mode ("No Signal", I believe) seemingly randomly/chaotically and without warning. No amount of mouse-waving and keyboard-smashing will wake the displays. The displays will not receive a signal after being turned off then on. Then, not immediately but after some undetermined time, the desktop hard drive light will begin to blink at a consistent 1-second interval (approximate), as though it is stuck in a loop.
My guess, based on both our office's experience and the posts I've read with the same problem (see below for links), is that this update would have become available either November 16 or 17, November 15 at the earliest.
Thank you for your attention to this conundrum!
Aaron
One more piece, not sure if relevant: a user connected remotely in order to monitor the desktop, but detected no problems with the machine. Unfortunately, I was not able to remain with the desktop to see if the displays had shut off at any point during his monitoring.

If you think that the issue is related to a recent Windows 7 update then try going back to a known good restore point before the issue occured.
