External LCD recognized as CRT. Weird?

I have a new Neovo F-419 19" LCD connected to my 12" G4/1.33 via mini DVI to DVI, but the monitor is listed in Apple System Profile as a CRT. Also, in the monitors OSD, in the Signal Input window, the setting always remains at Analog. I'm unable to select Digital. When I save the setting (Analog) the screen goes black for a second as it resets, but a message appears onscreen "No Signal". Weird, no?
I'm asking all this because, while the monitor is okay as it is, I am still not 100% happy with what's onscreen. Text is not as sharp as I'd like. I am expecting a little better performance out of it and I thought a DVI digital connection might really improve things.
Any chance that there's some incompatibility with the powerbook's mini DVI port? Shouldn't be, but who knows.

Equium A100-147 - Native resolution on external LCD doesn't work

Hi,
My Equium A100-147 has 1 VGA and 1 S-Video output, so I'm using the VGA output on a external LCD monitor with native resolution of 1680x1050@60hz, but the integrated Intel 945 graphics card doesnt give me the right resolution to choose for this monitor, the most close is 1600x1200 and some another weird widescreen resolutions that make my monitor scaling show a ugly image.
So I tested another external monitor with native resolution of 1920x1200, and the closest resolution the Intel drivers gave me was 1920x1080, even installing both monitors drivers, removing and reinstalling the driver and even formatting the machine and reinstalling everything from zero didn't give any different results.
I have another laptop MSI Wind with the same graphics card built in and the very same driver version, and the laptop detects both monitor and the right resolutions for them, so it's not a monitor driver problem.
Seems for me that is a problem with the S-Video output that makes this mess, but there is no way to disable it in the BIOS or any another place in device manager I have seem yet.
Does anyone can give me some advice for what can I do?
Thank you!

actually the resolutions available to external monitors here on the intel control panel are
800x600
1024x768
1280x1024
1400x1050
1600x1200
1856x1392
1920x1080
1920x1440
2048x1536
so it seems possible to use another widescreen resolution at least to match aspect ratio without matching the right resolution.
I've just hooked my 1080p hdtv via VGA and I'm able to use 1920x1080 16:9 aspect ratio
seeing this another resolutions that aren't on the manual, maybe its possible to make custom resolutions as well.
I've tried make a custom driver using the intel ones and power strip but without success because I don't know exactly the range of frequencies to setup the driver .inf

Blackmagic Intensity Pro problem plackback on external LCD TV

Hi there,
Recently installed Intensity Pro card on my Mac Pro and trying to work on FCP6. I use a 1280x720 9 sec footage for testing but there's a problem to playback on a external LCD TV via HDMI cable. The playback on FCP canvas plays fine but the LCD TV just showing a still image. I've tried to test on a SD 720x480 footage which works fine both on FCP canvas and LCD TV even a general CRT 4:3 TV. Sure I have select the Video Playback under View to "Intensity HDTV 720p 60". Are there any other settings need. Will anyone knows what happen or need any settings? Please advice.
Many Thanks.
Kory

Kory - the BlackMagic card is temperamental.
With FCP, I've found that if I capture using the card, for a few seconds, that the output to the HDMI monitor gets 'fixed'.
Or, sometimes it will just start working on its own. Maybe after I stop and re-start FCP.
I even returned my card for replacement. Unsure why they have such issues. But once you figure, by trial an error, a technique for getting the display to work, it does basically work. It's just quirky.
With Motion output, sometimes I have to use the wrong output rate to see the output, and - then suddenly it will decide it wants the correct output rate.
But, I'm going out at 1920 x 1080 - and haven't tried other resolutions.
Good luck. Try complaining to BlackMagic and see if you can escalate the problem up the food chain. Maybe if enough complain they will fix it (they were telling me that it wasn't supposed to display 1080p, but it certainly does - well, somehow converted to 1080i by the card or by FCP).
One other thing you might try, is an HDMI switch from monoprice. Might help with locking on the hdmi output. I use one of those for monitoring from hdmi input of camera, and I seem to remember playing with it while dealing with the no picture, or still picture issues of HDMI output to my monitor.

Your Suggestions on Adding External LCD / LED Monitors to MacBook Pro?

My current work station is a PowerPC G4 Dual 867Mhz with dual 19" CRT displays. I use this for design work (Adobe Illustrator); photo restoration (Photoshop); & online sales.
I was down to my last two CRT monitors, and wanted to perhaps start porting some of the graphic intense work to a faster computer so I bought this MacBook Pro:
http://support.apple.com/kb/SP499
I have not actually had a chance to use the MacBook Pro - it and all the accessories are still sealed - I couldn't afford the down time to set it up.
I am wanting to add a external monitor to the MacBook Pro that would be suitable for detailed design work with accurate color, true blacks, and the ability to be correctly calibrated. Since I may be still doing work on the G4 with software that will not run on the MacBook Pro I'd like to perhaps buy 3 matching monitors , 2 to replace my crt units and 1 for the MacBook, so that I can closely match the design output between the G4 and MacBook Pro.
I briefly tried a inexpensive LCD TV with a PC hookup on the G4 to get some idea of how an lcd would look. The LCD TV had a native resolution of 1440 X 960, which is a 3:2 aspect ratio, but that resulted in designs elements being distorted (i.e., squares look like rectangles). In 4:3 mode the TV did not distort the design elements, but the picture was not crisp / sharp and appeared soft. From what I've read this is because the lcd, unlike a crt, can't correctly emulate resolutions other than the native resolution built into the screen (i.e., its software guesswork). I also did not like the fact than in 4:3 mode it left black areas on the right and left edges of the screen.
I typically work in a 4:3 aspect ratio with a resolution of 1024 X 768, but a higher resolution of say 1600 X 1200 would be o.k. So what are your suggestions as to finding a lcd / led monitor that has a 4:3 aspect ratio? So far I've found limited information on what appear to be old monitors - there's one on Dell's site; for example, that says it has 1600 x 1200 native resolution, but a review also says its the same monitor they've been making for 5 years (besides I don't think I'd like the idea of hooking a Dell into my Mac). Found a few references to Lacie and NEC.
I really don't understand the monitor manufacturers, including Apple, that claim their monitors are for design work, when they don't offer native a 4:3 aspect ratio. How exactly am I to complete designs when circles are ovals and squares are rectangles?

"Take a flash drive with some representative PDF files saved from Illustrator to your nearest Apple Store or Apple reseller and ask for a demonstration using one of Apple's beautiful 27" 2560 x 1600 monitors. It would replace both of your 1024 x 768 CRTs with lots of additional desktop real estate to spare."
1. Well, actually no since I do not have fixed 1024 x 768 crts since crts do not have fixed resolutions. I can easily set each monitor to a variety of other resolutions including 1600 x 1200. Actually the Apple display would be a step down in total working area if I used the largest common resolution of 1792 x 1344 and certainly not worth the extra cost for the space gained if working at 1600 x 1200.
2. Unfortunately the display requires 10.6, which does not work on a G4 Dual 867Mhz. It would not even work on my MacBook Pro that I've not had a chance to use yet as it comes with 10.5. Also, 10.6 drops supports for PowerPC emulation so that means buying hundreds of dollars in new software. I use Apples only, but one thing I hate about the company is what many perceive is their "elitist attitude" toward their users - do they really think most people in the real world have so much money that in order to use Apple's new 27" display that they have to go out and spend more than the display costs on updating their computer and software. I am not a zombie fanboy willing to buy anything just because it has Apple on it.
3. Like most people I do not live by an Apple store or a Apple reseller, even the local Best Buy does not carry Apple computers in their store because the retail space does not justify the resulting sales (not that I would buy anything there anyway as they are over priced). I am really not interested in driving several hundred miles to the nearest store.
4. For a $1,000 I expect a monitor to offer a native 4:3 (1600 x 1200) aspect ratio - certainly Apple knows that this is the preferred working environment of many CAD and graphic users but they chose not to offer this in the display, thus the Apple display is really seems geared toward pop corn munching movie watching consumers.
5. This display is not actually made by Apple, its probably LG or one of their other suppliers.

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.

External LCD flicker (timing standard problem?)

My external LCD panel flickers when connected via DVI. It basically looks like a CRT refreshing. If I connect it with VGA, it doesn't flicker. It doesn't flicker when connected to a different machine. And it doesn't flicker if I boot the machine into Windows.
I've tried setting different refreshes on it with SwitchResX to no avail. Again, it works perfect in Windows, but my built-in LCD has whine in Windows when not at full brightness. So, in handy chart form:
OS X
Built-In: Perfect
External: Flicker
Windows
Built-In: High pitched whine when not at full brightness
External: Perfect
The only conclusion I can draw from this is that it is related to the use of different timing standards or something of the like. Clearly all the hardware is fine.
So, does anyone have any idea how to go about changing the timing standard used in OS X?

I'm experiencing almost the same problem as you: When I connect an external LCD projector to my Macbook Pro via DVI/VGA adaptor, I notice a flickering of the LCD projektor. The intensity of the flickering seems to depend on the frequency I adjust in the monitor control panel. Unfortunately there's no frequency that fits the needs of the LCD projector.
Any idea to solve this problem is most welcome!

Screen no longer works, help getting set up with external LCD?

So my Titanium Macbook Pro's screen went out yesterday and it's no longer covered so I've been trying to figure out how to get it to work with an external LCD monitor.
I can get it to boot up, and I can even get it to open itunes via Spotlight and hit play and hear music, so I know all else is (hopefully) fine.
The monitor I have is an "Acer LCD Monitor AL1916W A" and I have the adaptor going out of my MBP to a VGA cord that then connects to the Acer.
I read this page to get the idea to do this: http://osxdaily.com/2010/12/21/broken-macbook-pro-screen-turn-it-into-a-desktop- mac/
But I cannot get the Acer screen to recognize the MBP and show an image. The Acer powers up and shows it's logo but then says 'no signal'.
I tried to blindly Spotlight > System Preferences > Displays but can't get anywhere from there. I tried to restart it and close the screen but no-go.
Help?

How to switch off laptop screen when you connect external LCD?

Hello, being new to Mac I'd like to ask if it is possible to completely switch off the laptop screen when you connect an external LCD screen and use it as your main desktop. My MacBook Pro does that automatically when I launch a full screen game, say World of Warcraft, but I would like to be able to do it manually.

If you have it connected to a keyboard and mouse, you just shut the lid and use it that way. Of course, I'd be curious why you wouldn't want to use the screen. Having two screens can be extremely useful. The only problem with it is that then you may miss it when you are away from your second screen!

My New External LCD is blurry with the Macbook but not my PC

So I recently bought a widescreen 19" LCD (1440 x 900 native). When I'm using my PC through the monitor's VGA connection, the image is nice and crisp. When I use my Macbook through the DVI port, the image is significantly blurry. Both are running at the monitor's native resolution.
Any ideas what might be going on here? It's usable but very annoying and disappointing.

I believe the max resolution for macbook is 1280 x 800 (internal/built in), which is lower than external lcd native resolution. But here is said :
Extended desktop and video mirroring: Simultaneously supports full native resolution on the built-in display and up to 1920 by 1200 pixels on an external display, both at millions of colors
taken from the macbook specs table.
Do check the system preference of what resolution displayed on the external one, and change the resolution back and forth and see which is the best resolution for it.
Good Luck

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.

Brand new macbook pro 15" when connected to external LCD display in high resolution ,flickers often

Hi,
I have brand new macbook pro 15" with retina display.
I have connected external LCD display (Samsung B2230) using Apple VGA adaptor & thunderbolt port. But LCD display flickers quite oftenly. I read community blogs where many macbook pro users like me are facing similiar issue.
There is no problem with LCD display as it works fine with Lenova laptops.
Can anybody please provide me the solution to this problem.?

External LCD Monitor - Older MBP

I have an older Macbook Pro, 2.16 C2D. The Graphics Card in it is an ATI Radeon X1600. I want acquire an external LCD monitor and I want to get one that is at least 1920x1080. Will I be able to use an HD monitor with my MBP and will it still look normal? Thanks.

The very first MBP (CD 2.16) supported external monitors up to 2560x1600,(such as the Apple 30") psiforce. So does the C2D with ATI Mobility Radeon X1600. See http://www.everymac.com/systems/apple/macbook_pro/stats/macbook-pro-core-2-duo-2 .16-15-specs.html
Any of them can do little 22 & 24" 1920x1080 monitors with one hand tied behind their back!
Cheers

Quality of screen color flashes after connecting to external LCD monitor

After connecting my Powerbook G4 to an external LCD monitor via s-video, the quality of the image on the built-in screen flashes back and forth between what seems like a 8 or 16-bit image and a 32-bit image. I have run the hardware test and everything checks out fine but the image is grainy and washed out and only sometimes returns to normal. I have also reset PRAM and PMU to no effect, as well as tried recalibrating the display. And oddly, the external display is fine.
This is terribly frustrating as all colors are washed out and I can't truly gauge what I am doing design wise. Any help is greatly appreciated.
Thanks

Thank you, Silly Rabbit. I actually only hook the Powerbook up to the external monitor (LCD TV) to watch movies, show photos, etc. I don't actually use an external monitor on a daily basis.
Your suggestion is a good one, which I appreciate. I am going to the Genius Bar this afternoon, so hopefully they can provide a solution for the built-in screen.
Thanks again!

Windows 7 Laptop to external LCD monitor show low resolution

Hello,
I'm connecting my laptop to external LCD 1920*1080.
When Extend the display, each screen works with its full resolution allowed (Laptop has lower than 1920*1080 and the LCD works with resolution of 1920*1080), but when duplicate the display, the LCD has a black frame and the desktop is only at the center
of the screen and not an all the screen.
Is it possible, when duplicate the display, that each monitor work with full Resolution? or when
dup the higher resolution will be according to the lower resolution?
thanks.

Connecting Powerbook to External LCD Monitor

The D-BUS port on the external LCD monitor is a female port, so is the VGA port of the DVI Adapter, How can I connect these 2 if both are female ports, what do I need???

Sounds like you need a VGA cable with male VGA plugs at both ends. Quite common, for VGA monitors that don't have hard-wired cables.
