Dual Monitor displays weird colors

Hi there,
Yesterday I bought a Displayport to HDMI adapter (Mini DisplayPort Male - HDMI female) for my MacBook Pro 15" (Late 2011 version). I use this to connect my MacBook Pro to my Philips 32" television. Everything has been set up (I've adjusted the resolution of the TV to 1080p and put my refresh rate to 50 hz since my TV doesn't support 60 hz). But once in every 5 - 15 minutes or so, my screen turns green for a brief second and suddenly my background or whatever is on my second monitor turns in to weird colors. Sometimes it takes about 2 or 3 seconds and it switches back to how it normally was, but sometimes it takes way longer. I don't mirror my screen, I use it as a second display. But I can't figure out why the screen it switching betweens there colors and don't know how to fix it. I've looked it up on the internet, but couldn't find anything useful. So I hope you guys could help me with this.
Thanks in advance.

Oops, I see that I'm in the wrong forum. Sorry about that.

Dual Monitor display/firmware difference

I purchased a Pavilion 27xi monitor from the HP Shopping site in October 2014 and purchased an additional 27xi to be used in a dual monitor setup. I received the new monitor this week. The newer monitor does not match the color/white of my existing monitor. When I move a white rectangle so it displays on each monitor, on the new monitor it appears as greenish gray instead of the white of the older monitor. I have done the factory resets, switched display adapter outputs (NVIDIA GeForce 9800 GT), tried one monitor at a time on either adapter output. All with no change in the behavior of the new monitor. The internal setup/control menus of the monitors differ in content and style/color.
Older monitor info: manuf: April 2014, Rev: RIM111
New monitor info: manuf: Dec 2014, Rev: RIM232
I have talked with HP "support" and one person thought it was because of the revision level difference.
I want the display quality of the older monitor, Rev: RIM111. If the monitor difference is because of the revision level, can the newer monitor be put at the RIM111 level. I tried to purchase a monitor with the RIM111 level and was told by HP Shopping that they do not have any at that level. I this a firm level that can be changed? If so how do I accomplish that?

Hello @tomas44,
Welcome to the HP Forums, I hope you enjoy your experience! To help you get the most out of the HP Forums I would like to direct your attention to the HP Forums Guide First Time Here? Learn How to Post and More.
I understand that the newest monitor you have connected to your desktop computer does not match the color/white of the existing display, and I would be happy to assist you in this matter!
To ensure that your system is properly configured for dual monitor displays, I recommend following the steps in this document on Using Two or More Monitors with One Computer (Windows 8). If everything is setup accordingly, I recommend following the steps below for the newest monitor:
Step 1. Unplug the power cord from the back of the monitor and the wall
Step 2. Hold the power button down for at least one minute
Step 3. Plug the power cord back into the monitor and then into the wall outlet (not a power bar or surge protector)
Step 4. Press the Menu button on the monitor
Step 5. Navigate to the Factory Reset option and select it
Step 6. Try a different cable connecting your monitor to your computer
If the above steps did not resolve your issue you can try the monitor on a computer or other device to see if the issue persists. Please call our technical support at 800-474-6836. If you live outside the US/Canada Region, please click the link below to get the support number for your region.

Dell Optiplex 780 standard size tower PC dual monitor display port graphic cards

Yes, only my boss informed me that they have to be display ports, he didn't tell me why.
I'm unable to buy from ebay or craiglist either & my local vendor doesn't have any in stock.

Quite a mouthful I know! but I need these specific graphic cards, ideally with next day delivery:

Dual monitors, ICC profiles, color management...problems

Problem:
An image displayed in Safari and then pulled off the web into Photoshop shifts colors noticeably. This is esp. apparent in a side-by-side comparison on the same monitor with the Safari window open next to the Photoshop file window…they look very different.
Possible clues?
When I drag an image in Photoshop from one monitor to the other it shifts color after I release the mouse. In my two-monitor setup one is a large LCD (that's the "main" one) and the other is a MacBook Pro laptop. Even though they both have ICC profiles the laptop is slightly more saturated than the LCD…and Photoshop seems to mirror this but exaggerate it. For example: I pull the same image pulled off the web into two separate Photoshop files and then I display one on each screen: the one on the laptop will be /much/ more saturated than the one on the LCD.
In the end, if I have 4 windows open of the exact same image (2 on each screen: one in Photoshop and one in Safari) I am looking at 4 differently colored images - with the Photoshop images appearing even more exaggeratedly different than anything.
Obviously I understand that the two monitors will never look identical, but Photoshop seems to be imposing some extra color management on my files that makes it impossible to use with my previously very helpful dual-monitor setup.
Specs:
- Dual monitor setup: both are calibrated using an i1Display 2 from x-rite and have their own different profiles (this is new as of this week)
- Mac OS 10.6.6 (w/all current updates)
- Photoshop CS3 10.0.1 (w/all current updates) :: Edit>Color Settings : set to North America General Purpose 2
Help?

Just read this entire thread and wanted to leave a few comments and qualifications, first a couple of FACTS for all to consider.
1) I am not "new" to color management - in fact I am quite experienced in color management at a commercial level since the days of film back when getting "accurate color" was actually difficult. At this point it should be easy if the involved software is working correctly and impossible if it is not.
2) I have the top of the line color management solution provided by one of the top players in the color management market and am using it properly as verified by their technicians.
3) I am running 10.6 on my main computers. Mac Pro, 2 27inch iMac sandy bridge quad cores, and am using mac cinema displays (new ones) on all of them.
Now the rant - I have been trying to run down this or a similar and related issue for over a year. If you happen to be experiencing the same issue as I am, which I will summarize as trying to get 2 displays to display anywhere near the same color (even identical monitors) do not bother upgrading to CS5 as I am using CS5 as well as a bunch of other tools (Aperture, LR, etc, etc) - this is BROKEN and all I can get from any of the vendors involved is finger pointing from one to the other. Each of them wants to blame the other vendor for not doing something correctly but NONE of them can actually give me any details as to what exactly is the problem.
At this point in time I am holding the color management vendor I use to create the profiles responsible - the reason that I am doing that has nothing to do with what exactly the technical problem is. It s purely because they claim that the product is compatible with OS 10.6 and they claim that their software does EXACTLY what I want = mach two monitors. Now we all know that different monitors have slightly different gamuts but at the end of the day if two identical colors fall within the gamut of both monitors they should display the same. They don't. I have worked with my color management vendor for 6 months on this, they agree that it is not working properly, they blame apple but they cannot tell me exactly what the issue is.
If a company advertises and sells a product they claim to be compatible with a particular brand and version of hardware and software and they claim that it will manage color consistency across multiple monitors (even on differing machines) then I believe they are ultimately accountable for ensuring it actually works and resolving the issue - whatever it is, if it fails to function properly.

Video displays weird colors with normal sound

I recently downloaded the newest version of quicktime (itunes said it was required) and also service pack 2 because that was required for the newest quicktime, but now when I play videos, they are playing (I can hear the sound), but the video is just a weird display of colors and shapes.

Open the QuickTime Control Panel / Advanced tab and check the box for "Safe mode".
Quit and relaunch QuickTime Player and try the files again.

W530 Dual monitor display

Is it possible to set the graphics card for the laptop display to use the nvidia Quadro instead of the Intel integrated chip?
Right, now the resolution for the laptop screen is at 1920x1080
and the resolution for the external monitor is 1600x900 (native)
The external monitor display is fine, but the laptop display is shrunken and there are huge black bars on all four sides.
Solved!

BIOS setup -> config -> Display -> Graphics device -> discrete graphics.
And I also set "OS detection for nVidia Optimus" to DISABLE (from default of ENABLE).

This guarantees using only Quadro graphics, for both internal laptop screen (if you want to use it) and external monitor (if connected).
If you really want to use BOTH laptop LCD screen as well as external monitor (simultaneously, in "extended desktop mode") then in nVidia Control Panel you must activate both monitors in the "set up multiple displays" dialog.
Link to picture
I have my external 1920x1200 monitor connected using the DP connector from my K1000M on my W530, and the laptop screen is 1920x1080. As you can see from the above, each screen is independent and can be set at whatever resolution you want ("native" or otherwise). I have no black bars anywhere when both monitors are enabled and active. Each monitor runs full-screen in its own unique "native" resolution (set through nVidia Control Panel's "change resolution" dialog), as the above graphic implies and as we want.
And of course, you also need to have Windows desktop display properties (right-click on desktop, select "screen resolution") configured for "extend mode".
I do not use the VGA connector. I use the DP connector, and "discrete graphics" in the BIOS, with "nVidia Optimus" disabled in the BIOS. I'm also running native nVidia 332.50 retail drivers, downloaded from nVidia site (not Lenovo Optimus driver).
NOTE: I normally do NOT run with both external monitor and lapsop LCD screen both enabled, in "extended desktop" mode. Instead I only have ONE monitor enabled with nVidia Control Panel. I see no point in using a tiny 15" laptop screen at 1920x1080 along with a 24" external monitor at 1920x1200. One or the other is fine, depending on the situation.
Then, in this single monitor mode, if the external monitor is connected and powered on Windows comes up using the external monitor (and not the laptop screen) at its native 1920x1200. If the external monitor is disconnected or powered off, Windows comes up using just the laptop screen at its native 1920x1080.
No internal Intel HD graphics used at all. This is all using nVidia K1000M exclusively with external monitor connected via DP connector, one monitor or two (in extended desktop mode or even "clone/duplicate" mode if I wanted).
For me this is perfect.

[SOLVED] Dual monitor acting weird on Fluxbox after system upgrade

Hello.
I'm using Fluxbox on Xorg. I have two monitors and for more than one year my setup has been this in ~/.xinitrc:
#!/bin/sh
if [ -d /etc/X11/xinit/xinitrc.d ]; then
for f in /etc/X11/xinit/xinitrc.d/*; do
[ -x "$f" ] && . "$f"
done
unset f
fi
xrandr --output DVI-0 --mode 1920x1080 --pos 0x0 --output DVI-1 --mode 1680x1050 --pos 1920x0
exec startfluxbox
Now, I just upgraded my packages (fluxbox and some xorg-* packages were upgraded, like xorg-server, as well as xf86-video-ati) and, although the dual monitor setup works, it seems like each monitor is not recognized individually. My Fluxbox toolbar spans on both monitors horizontally (whereas it used to reside on the left one) and when I maximize a window, it's maximized on both monitors (whereas it used to be maximized on one monitor only, the closest).
Before reverting the upgrade, anybody knows why this is happening?
Thanks,
Phil

Freezes, Goes All Crazy or Displays Weird Colors

I have the latest 14 inch iBook (1.42 GHZ, 1G RAM) purchased at the end or Sept. 05 running Tiger 10.4.4 and these problems have been happening just about the entire time. I've never had it repaired and I just recently did an Archive Install to try and fix it but nothing.
Every day my monitor will get one if not all of these problems:
1. Big squares of a red to green gradient show up over icons, text, palettes etc. out of no where. When I switch out of the program with the squares and back in they're gone but it happens all the time.
2. My monitor will have a seizure; it's the equivalent of having the TV on the wrong channel, it going all black and white and making that loud noise. Mine's all different colors and doesn't make a noise but the rest is the same. I have to hit the power button and restart to get rid of it.
3. The last is the OS just freezes; it freezes about 4 times a day. I've done the hardware test and everything passed but nothing's changed.
I need my computer every day for work and can't spare the time to send it away to get fixed. I was hoping this was a common problem and there was a fix I could do myself before I have to ship it off.
Bah?

The last event was at 11:50 this morning. Machine froze and took about 3 restarts before it would boot back up without erroring out.

Macbook Pro late 2011 with Thounderbolt, will it support dual monitors display?

I have recently working on this Macbook pro, and wasn't able to find accurate information about the dual display solution for this MACBOOKPRO model.
It has thunderbold port.
Have anyone happen to have this model and successfully connected with two conventional monitors?
Conventional monitors I mean, VGA, HDMI, or DVI.
Thank you.

Hi O,
According to MacTracker, the answer is a clear no for the 13" and yes for the 15" and 17".

DUAL MONITOR DISPLAYS

Anyone know of a way to keep the second monitor active when an application on my iMac screen is set to use "Full screen" mode. I can be anything from a game application to Aperture or even YouTube videos; any full screen mode seems to do it.
I bought the Apple brand Mini DVI to DVI adapter to connect the second display.
Thanks in advance for the help!

It's up to the application as to what happens to the second display when full-svreen is used.
For example, MPlayer OSX Extended can be set to run in full-screen mode and leave the second display useable while watching movies or DVDs.

Seamless Windows and Dual Monitor Display

Seamless windows open spanning both display monitors regardless of the settings I use to prevent it. It's like the SGD thinks both monitors are one big display and doesn't open things in just the default monitor. An application that opens maximized will cover both monitors!
Has anyone else had this problem and found a workaround? We are using Windows XP client (Dell laptop), IE6, 2 display monitors (NVidia graphics card), and the application server is Windows 2003, SGD is 4.2.

It is an individual application we are publishing in the seamless window, but that one application launches many applications from there -- it is basically a toolbar for launching a whole host of other applications.

My iPad screen suddenly started displaying weird colors

Hello, well I was using Twitter on my iPad 3 when suddenly the screen started to got really weird.
(The picture: https://twitter.com/rgonzalezagui/status/469652534236561408)
I'm not sure if the pixels are dead now, I have never ever dropped my iPad, I have never had an accident with it. Please help me.

First, try a system reset. It cures many ills and it's quick, easy and harmless...
Hold down the on/off switch and the Home button simultaneously until you see the Apple logo. Ignore the "Slide to power off" text if it appears. You will not lose any apps, data, music, movies, settings, etc.
If the Reset doesn't work, try a Restore. Note that it's nowhere near as quick as a Reset. It could take well over an hour! Connect via cable to the computer that you use for sync. From iTunes, select the iPad/iPod and then select the Summary tab. Follow the on-screen directions for Restore and be sure to say "yes" to the backup. You will be warned that all data (apps, music, movies, etc.) will be erased but, as the Restore finishes, you will be asked if you wish the contents of the backup to be copied to the iPad/iPod. Again, say "yes."
At the end of the basic Restore, you will be asked if you wish to sync the iPad/iPod. As before, say "yes." Note that that sync selection will disappear and the Restore will end if you do not respond within a reasonable time. If that happens, only the apps that are part of the IOS will appear on your device. Corrective action is simple - choose manual "Sync" from the bottom right of iTunes.
If you're unable to do the Restore, go into Recovery Mode per the instructions here. You WILL lose all of your data (game scores, etc,) but, for the most part, you can redownload apps and music without be charged again. Also, if you have IOS-7, read this.

SL500 dual monitor display

I was wondering if someone could help me. I have an SL500 and need to hook up 2 projectors to it to display the same image from the laptop on 2 screens. I have done a little research, but there are so many options and I'm not sure if I am considering the most efficient method of doing this. I also am a bit intimidated by all of the specifications and am not sure if what I was going to purchase would be compatible.
The 2 projectors I need to connect to are a Dell M410HD and a Dell 2300 MP. I was looking at splitters on this site, but don't know which one is the best/compatible for my laptop:
http://www.startech.com/AV/Splitters/VGA-Splitters/
Thanks in advance.
Solved!
Go to Solution.

vga splitters will do, but if your cable is too long, the signal will degrade.
Alternatively you can use the Dell M410HD with your HDMI port, and the Dell 2300 MP with the vga port. This will give the highest quality.
