OS X :: Screen Resolution Gone Awry - Blocky With Bold Colors
Aug 1, 2009
Everything is very difficult right now as my iMac has turned into a print by that "15 minutes of fame" bloke. The screen resolution has gone completely strange and everything looks really blocky and boldly coloured... but only for one user. If I log in under my wife's account everything is fine. I've been through all the system settings a dozen times, and tried changing the resolution back to max and colours back to millions, but nothing helps. Googling for the problem doesn't find anything either. I've even tried a time machine restore of my area to earlier in the day, but that doesn't seem to help (although it won't let me restore my home directory, as the restore button is grayed out). When I switch users, the resolution jumps back to normal for a fraction of a second... just before I switch away to another user. A kind of "here's what you could have won" teaser. Likewise, when I switch back, all looks OK for a split second.
1440x900 resolution of the new MacBook Air 13.3" screen is simply too high, making everything way too small and straining on my eyes. Is there a replacement LED LCD panel with a lower resolution (1280x800 like the old MBA) that could be retrofitted?
i am using a hackintosh for a week now. I am using it just to get used to Mac OS X because i am switching to a Macbook Pro in a couple months. I switched from PC to Mac officially now. OK, let's come to the main topic of this thread;-At first, my hackintosh couldn't get my gfx card, i couldn't find the driver(kext) so my resolution was very bad. Everything was huge and blurry. I couldn't even look at my 17" Samsung LCD screen. I made an entry to file which was something like this
I have a late 2006 Macbook, and my dad has an early 2009 Macbook. I was comparing the two today and noticed that there was a significant difference between their LCDs. My dad's Macbook has a lighter, more normal display. While mine has a yellow tint to it and is darker. Both computers were on the same display profiles and both had the same brightness set.
Is this just how LCDs are as they age? Or is mine really not supposed to have that yellow tint? The new Macbook is on the right in the pic.
Using the ati flashing tool I flashed the XFX 4870 1GB ZFWC. When I start up a dialog shows up saying the cables are not connected, when in fact they are (I have double and triple checked). Also when I put the computer to sleep then wake it up a weird distorted blocky pattern appears and I have to restart the computer to fix the problem.
It seems that in his nasty habit of taking naps while resting a body part on the keyboard, he has managed to press some obscure key combination that has inverted the colors on my screen (like a color photograph negative). I've searched everywhere to try to revert this, but had no luck so far. When I restart, and/or log out and back in again, the screen is normal during the booting sequence till I choose the account I want to log in with, then it immediatly goes into "x-ray" mode. If I choose another account, it will boot and log in with no screen problem whatsoever. So this must be either a preference option has been changed via keyboard command or the account is corrupted. Right?
Today while working with an InDesign document it crashed and I had to reboot the hard way. After starting up again the colors of my screen was all twisted and strange. It's like a very high contrast/bad resolution. Except for the screen-issue the machine works fine. I tried changing setting in preferences/display (no. of colors, resolution and color profiles) didn't work. I then tried resetting the PRAM, which didn't have any effect either. I tried creating a new user and logging into the account - and it looked fine? It's probably just a pref-file that need rebuilding or the like, but I have no clue as to where that might be. I work on a G5 PowerMac with Tiger on it.
In display in system preferences there is a tab with "Millions," "Thousands," and "256" colors,but 256 colors is dimmed. How do you set your MAC display to use 256 colors so I can play an older game?
1. Today, I turned on my MacBook running 10.5.7 bought in the Summer of 2006 and the colors were washed out/faded. They were noticeably more bluish-purple. This is the third time it happened over the past year, so it is incredibly hard to replicate for a genius. A restart fixed the issue. I did not mess with the color schemes (I actually don't even know how to use them), nor have I dropped my laptop in the past three years I have owned it. Anyone know what is the issue here? I'm pretty sure it's hardware-related. I am concerned because my AppleCare is expiring this coming September, and I don't know how to replicate the problem.
2. Also, after a good period of nonuse, one-fourth of my screen (the lower left corner) is noticeably "darker" after I turn it on. The area goes back to its correct brightness after 10-15 minutes, like the screen has to warm up first. I've had this problem since I first purchased the unit but this dark spot has definitely gotten bigger. Is this normal for a laptop?
3. Coconut battery says that I have only gone through 4 battery cycles. I've calibrated the battery and the program still says the same thing. The battery I replaced quite a while ago did not have this problem.
I have a 3.06 GHz, 4 GB, iMac running 10.6.1. and I have a weird problem: while I was running Windows 7 under Boot Camp, during a simple task, my screen suddenly turned a solid shade of gray. Having no other option, I held the power button, turned off the computer, and turned it back on.
When I booted back to OS X, it happened again immediately upon opening iTunes. This time the color was solid black. Concerned, I turned off the computer, waited a moment and booted it back up in Safe Mode, where I currently have no problems whatsoever. From Safe Mode I repaired my disk permissions, cleared my caches, and zapped the PRAM while restarting my computer back into normal mode. Unfortunately the problem persists, this time my screen turning a solid shade of dark purple.
I'm going to call Apple Care in the morning, but has anyone heard of an issue like this? I searched the forums for a solution, but wasn't sure what terms to search for.
When I turned on my computer this morning the display was off center and could only see one half on the screen and the other half was black and all the colors were off lIke all the things that are normally blue were a weird reddish orangey color.
Well today I was using the screen capture (in Quicktime X) on the 9600M GT and the result every time was that the colour was all screwed (see in attachment) I tried it on the 9400M and the screen capture was fine. I'm wondering if this is specifically a hardware issue or something that software may be able to fix. Currently, I have not ran into any other problems with the 9600M GT. Is this happening to anyone else, or can anyone else test it out to see if it happens to them?
Suddenly yesterday when I powered mi iMac I had some horizontal green bars on the startup screen then it powered normally. But it happened two times, now every time I power on my iMac the screen stay black, and i can use my computer, everything else is working normally (i still can use Alfred to turn off my computer).
I already tried resetting the Command+Option+P+R, it didn't work. Also the Safe mode.
Thing is I got hold of a 1ghz 17" iMac almost for free, it had a dead logicboard (I checked it with a voltage-meter), but I figured I could fix it and have a small hobby project-thingie going on. Well I just got a new logic board today, for a 1ghz 17" iMac g4.
Things is I only get a bright grey screen from my Mac when I boot. I've tried connecting it to a external display and that works fine. Everything is there.
I then reinstalled Tiger on it, with the computer connected to my external screen. And I still have the same problem. (I have now disconnected the ext. screen and is controlling the iMac from my MBP). So at least it isn't the installation.
So what is the problem? I can via an Apple Keyboard control the brightness on the blank screen, which would indicate that it does react to input of some degree.
I've read that if the inverter is dead or anything else is dead, you would get a rolling grey screen, flicker or something like that and not a steady bright grey. One thing I'm thinking is. What if somehow this logic board was for a 15" 1ghz imac g4? Can I check this?
I read that long thread about guys buying hi-res displays for their MBPs, and they had to replace some display profile? Could I maybe fix it with a different display profile-file?
I'm really confused by all this, and would appreciate any help I can get.
Model: PowerMac6,1 CPU-Type: PowerPC G4 (3.3)
and
the gfx chip is a GeforceMX4 with 32mb.
The display is a mode 9c27, manufacturer 610, serialnumber 00000, manufacture date: B84D7200.
My tibook .867Ghz was working fine this morning, but now when I restarted it this afternoon, the colors are all off (lots of green and rapidly vibrating pixels in background). The computer works, I can run programs and so forth. There are no changes to the displays settings, still 1280x854 and colors "millions". When I switch to thousand or 256 colors there is no significant change.
How much battery life do you loose when going for the High-res screen. Some people are complaining about low battery life with their high resolution screen and I was wondering if there is a connection.
Do the standard screen get better battery life. If so, how much better?
while i am using my macbook the screen will suddenly go blue and flash between different blue colors like it is trying to work. sometimes it comes back on but most of the time it stays like that. I have to force shut down with the button and then restart...about half the time it is still flashing blue after the restart and if it does work, it goes blue eventually.
dont know if its a problem with the screen or what because the computer continues to work...if there is a movie on, you can here it in the background and the screen just flashes.
My wife and I have near perfect vision - for being average adults within our mid 40s. Within our Win XP and Win 7 systems, we set their Control Panel - use "large size" fonts and both fonts and menus become larger. Thus, allowing much better "comfort reading" on their default 1600x900 scren resoutions. Within one location, we simply change its "global level" font sizes and menu sizes, and still have clear screen images.
I just purchased a Mac Mini and am using a DVI to HDMI cable to connect it to my 42" Sony KDF-E42A10. I am unable to achieve full-screen resolution and downloaded SwitchResX to manually adjust the display. Does anyone know the timing parameters for the Sony or how to achieve full-screen resoltuion?
i changed my resolution on my mac mini to a size my screen cannot support and now have no picture to change it back. is there anyway of restoring the settings in startup
I hooked up my MP to an HDtv and chose an incompatible resolution. Now the tv says incompatible signal and won't fix upon restart. I tried resetting pram, but that doesn't work.
I set up SL 10.6.2 image using vmware player, and I installed Mac VGA driver for VMware. [URL]. Indeed I can change the resolution now, however it seems only the screen size is changing but everything else it still acting according to the default res. Meaning, the windows maximize won't open all screen (I have to stretch it myself), the tray icons (safari, system preferences etc..) are all very small, and more.
Recently replaced my internal hard drive and had to re-download and update everything... Forgot which version of Safari I had before with my OS X 10.4.11, so I got Safari v4.1.3... It works great, but I know the bold fonts were never THIS bold. Here is what I'm currently looking at:
I tried selecting "Never use font sizes smaller than 9", and I even tried "Empty Cache" as well as "Reset Safari...", but it's still ridiculously bold.
I've got a Samsung LCD HD TV with the resolution 1366x768 My TV (nej means no, and ja means yes), and a Macbook Pro 13" (2010 version, 2,4 GHz). I connect those two with a standard VGA cable, but I can't get the right resolution (1366x768). I've tried to make my Macbook sleep, so my TV id the primary screen, but I can't get the right resolution. 800x600 is the lowest, 1900x1080 is the highest, and the closest to 1366x768 is something like 1340x760 (not exactly that number, but it's pretty close). Can I get 1366x768 resolution my TV when I connect my Macbook?
I have just installed Windows XP Professional on my 13" mac using VirtualBox. Everything is working fine but i can not get the screen resolution right.
OSX is running at 1280 by 800 but Windows doesn't have this option, the resolution closest is 1280 by 1024.
