Lost full hd resolution output via VGA to monitor

Hello Everyone,
I was happily recieving full hd output from my macbook to my monitor via a VGA cable. I then disconnected the VGA cable (and the connected mini-displayport to VGA adaptor) from my macbook. I then plugged them back in as before. However, this time I can no longer select 1920*1080 (Full Hd) from my macbook's display settings for my external monitor. What went wrong?
Thank you

Not sure; you may try and check all settings after a reset
of the System Management Controller (SMC) to see if
that makes a difference. Or spend some time with a whole
pile of things, as some of us said in the early Mac OS X
days, throw the kitchen sink at it.
Boot into SafeBook mode, repair disk permissions, check
or verify the hard drive, get a coffee. Check the wires to
see if one of them went on permanent vacation, & so on.
Looking at 1:14AM here, so not sticking around...
Good luck with taming gremlins!

Forcing output via VGA on a MBP

So I have four monitors hooked up via an active VGA splitter, only problem is that while my MBP recognizes the VGA adapter (screen fades blue for a second) it refuses to actually output any image to the VGA port.

I am having the same problem. It seems to be an apple hardware problem. I find it very fustrating that all the windows driven computers i have been using over the many years have NEVER had any problem with output on external vga device.
how on earth can you use this computer for presentation when it simply dont work? (using DVI works with out any problem at all, its only related to VGA)
I have searched the internett and found out that the seems to be some devices it works on and some it don't. Maybe it outputs too low power on the vga?? but apple, can you fix this problem?! its very fustrating and it seems to me that there are sevral people having this problem. if this problem still persist, i have to drop using MBP's in the company i work, and move back to hp or lenovo.

Video Output via VGA "not authorized"

I have the VGA output cable for my iPad, but on my newer videos, it gives me an error message that the display is not authorized to view the content. Do you perhaps know how to authorize a display?

Rental movies and maybe some other purchased videos will not display on video out because of licensing reasons. There is really nothing you can do.

Resolution via DVI lower then via VGA

Hello,
I need your support for my new HW composition.
I have a new DELL Latitude E5440 and the fitting DockingStation DELL PR02X.
Connecting my monitor via DVI I get a max. resolution of 1440x900.
Connecting my monitor via VGA I get a max. resolution of 1680x1050 (max of monitor).
With my former laptop of FSC I could use the monitor via VGA in the highest resolution.
Can you please help me to get the high resolution via DVI?
Thank you very much for your help in advance,
Scorino

Hello,
the Docking station is using dual link DVI.
The docking station has two Display Ports...one under each DVI port.
Currently I don't own a display port adapter and no display with a display port.
Furthermore DVI dual link should be able to get a resolution of 2048 x 1536 Pixel, not 1280 x 1024.
I would like to use this docking station with DVI and high resolution (Full HD).
Currently I don't understand why this is not possible.
My last laptop was able to produce Full HD to my displays via the same cable.
Just the Laptop and the docking station changed. I'm sorry that I cannot connect DVI directly to the laptop, because there is no port available.
Thanks for your answer in advance.

Cannot get full widescreen picture (16:9) via VGA

I'm trying to setup my LCD HDTV as an external monitor for my MacBook. The issue is that the TV is not displaying a full 16:9 image from the MacBook; it's only showing a 4:3 image, so there are large black bars on the side of the picture.
Setup
- TV: Samsung 40" LN-T4061F HDTV (full 1080p resolution)
- Connection: mini-DVI to VGA, VGA to TV
When I go to System Preferences > Displays, it finds the Samsung without an issue. It even defaults the resolution to 1920x1080, 60Hz. But for some reason (in both mirror and non-mirror mode) the display on the Samsung is 4:3 so I don't get the full widescreen capability.
I can certainly try something like SwitchRes X but I thought I'd check the forums first to see if anyone could provide some help. Thanks in advance.

hey there jsizz,
does your TV have over/under scan? you might be able to get "fullscreen" w/ a miniDVI to DVI +DVI or HDMI cable. the MacBook "officially" only supports up to a 23" display, but i've successfully connected to my 42" Sony LCD Projector HDTV & gotten fullscreen using a miniDVI + DVI>HDMI cable, which has over/under scan control.
good luck.

Running a presentation via VGA out with Firefox/Safari open. When I hit 'esc' to come out of slideshow, monitor stated resolution too low. Now Safari and Firefox browsers are still open, but I can't see the browser window on either. Ideas?

If you use Lion, go to Applications/ Mission Control and, if you have more Desktops, as attached, it means you have more, and you must select the one you need for a certain app. If default settings has not changed, this is Control with left / right arrow
If in Snow Leopard and earlier, you have these settings in System Preferences only. In Lion, you also have some settings in Sys Prefs.

T61p and 1920x1080 via VGA?

I have Thinkpad T61p (6457-CT0) with NVIDIA Quadro FX 570M and internal LCD with 1680x1050 running on XP SP3, and now I bought Samsung SM2333HD 23” external LCD monitor with 1920x1080 (HDTV) resolution and I want to use dual view (int. 1680x1050 + ext. 1920x1080). The problem is when I connect ext. monitor via VGA with 1920x1080 - picture on ext. monitor is cropped from left, smaller and positioned beyond borders of visible area. Picture adjustments aren’t helping at all. When I lower resolution to 1680x1050 it is ok, but the image is blurry because it’s not native resolution of ext. monitor, so I don’t want to use it. When I try only ext. monitor with 1920x1080 with disabled internal LCD, there is still the same problem, and on 1680x1050 picture is ok, but blurry. Resolutions higher than 1920x1080 are not possible in Display Properties/Settings/Screen Resolution settings or in NVIDIA Control Panel.
I have borrowed Thinkpad Advanced Mini Dock with VGA and DVI output, and when I use DVI to connect ext. monitor, everything works fine and picture is ok, but via VGA on docking there is the same problem.
I have latest drivers for NVIDIA Quadro FX 570M from Lenovo 6.14.11.7715 (2009-01-08), and latest IBM Presentation Director 4.03 (2009-02-12), but I have also tried with older drivers and Presentation Director, but it’s all the same, only picture is differently cropped, smaller or wider. Also, strange thing is when I, , try to make a new Display Scheme in IBM Presentation Director on internal LCD + ext. monitor via VGA, it offers max. resolution of 1680x1050, which is not the case with DVI.
Just to be sure, I connected T61p via VGA to LG 32” full HD LCD TV, the picture has identical problems, so it’s not up to monitor. I have also tried to connect HP 6710b laptop via VGA to same Samsung SM233HD monitor and there are no problems, it can produce 1920x1080 with clear picture. I have also connected T61p via VGA to Lenovo L220x monitor, and now Display Properties/Settings/Screen Resolution settings (other than 1680x1050) offer 1920x1080 and 1920x1200 resolutions. When I set 1920x1080 the problem is identical, but when I select 1920x1200, picture is ok.
So my conclusion is that T61p is not capable of producing 1920x1080 via VGA correctly, although it can produce 1680x1050 and 1920x1200. The main difference is that 1680x1050 and 1920x1200 are 16:10, but 1920x1080 is 16:9, so I am guessing that VGA output on T61p has problems with 16:9? Or is there problem with sending analog signal via VGA when it exceeds internal LCD native resolution (1680x1050) only for some resolutions? I have tried searching Internet and forums, but there are no answers. Maybe it is the problem when internal LCD is 16:10 and external monitor via VGA is 16:9 and I use dual view? I think there should be no problems with Quadro FX 570M and I don’t want to buy Thinkpad Advanced Mini Dock just because 1920x1080 only works with my monitor via DVI which is present on casing of T61p (and because it’s firm’s laptop, not mine). Do you have any suggestions what is wrong with graphics adapter, drivers or VGA output or how can I solve it?
Solved!
Go to Solution.

Through NVIDIA Control Panel, which you should have if you installed drivers.. You can get it via Display Properties -> Settings tab -> Advanced button -> Quadro FX 570M tab -> Start the NVIDIA Control Panel.
In NVIDIA Control Panel on the left side in the tree select Display, Manage custom resolutions, select external display on the right and click Create...
In the Custom Resolutions window click on Advanced >> and (in Back-end parameters section) in Timing Standard select Manual. You'll be able to enter (in Advance Refresh Rate Parameters) under Desired refresh rate value from 59.500 to 60.499. I have tried 59.500 and it worked... You can also try to change other settings, if you understand the meaning. There is a Test button in the upper right corner.
Hope it helps...

DreamColor Monitor from PC via VGA: Color-Space & Settings?

Context:
Premiere CC on a WIndows 7 laptop with an external DreamColor monitor connected via VGA port (for convenience rather than bit depth).
What color space is appropriate in the DreamColor settings, i.e. what is the VGA likely to be supplying? DreamColor's config options are: [ Full | AdobeRGB | Rec.601 | sRGB | Rec.709 | DCI P3 Emulation ]. I'm guessing sRGB, but is that reasonable e.g. is it the Adobe kind?

Several questions spring to mind ... first, are you calibrating this with an actual "real" calibration tool, such as the i1Display units, anything? Because ... if the answer is no ... well, the output isn't set to any particular "there" before you even start, is it?
Next ... what are you going to be outputting for? B-cast TV? Critical web use? Your own YouTube/Vimeo channel for the heck of it? Family records? Whatever is going to be the "heaviest" output (meaning demands on color space) sets the minimum from what your choices can offer. Critical web work or such, you would either want the Adobe RGB or the Rec.709 I would think. For just fun stuff, the sRGB would work ok.
Fwiw ... Adobe RGB is a wider color space than "standard" sRGB. Rec.601 & Rec.709 are "broadcast" standards that include specialized base/gain/gamma settings. Rec.709 is the newer and far more common one of the two ... and it sets "black" as at value (in 8-bit terms) of 16 and "white" at 235. Data outside those values are used for technical purposes within the "system". Some modern video cams record in Rec.709, btw.

Static electric shock when hooked up to TV via VGA

I have a 2007 MacBook Pro and have been hooking it up to a new Samsung HDTV via the display output to VGA, as well as the audio out port. I have been streaming video off of Hulu or Netflix and after about 20 minutes of me sitting on the couch away from the computer and TV, I get up to cue the next TV show or change something with the computer and I get an electric shock when I touch the computer.
Any thoughts on what may be causing this? Its not the biggest deal but I don't look forward to it every time that is for sure.
Thanks in advance.

So is the solution just to wait till the seasons change?
Not sure if either one of us would call that a solution, but if it is static, the problem should get less and less as winter wanes and humidity rises (depending on what climate you're in, of course). I can't recall seeing any in the recent past, but there used to be products available claiming to lower static in households. I've never looked into them. I do try to be careful and touch something else grounded before touching my MBP as electronics and stray electrical charges are not a particularly good combination.

How to get MacBook Pro to recognize full 1366x768 resolution of Plasma?

When I hook up my MacBook Pro via DVI to my 1366 x 768 pixel Samsung plasma screen, the computer recognizes it as a Samsung PDP at 1024x768. The resulting image is stretched to fit the full 1366 horizontal pixels and thus ruins the aspect ratio. I know that I can switch the display mode on the Samsung to display 4x3 with black bars on the side, but what I really want is for the computer to take advantage of the full 1366x768. How do I do that?

Check your documentation. Most Samsung 1366x768 monitors do not support the full native resolution in DVI mode unless using a specific card to drive them made by PixelPerfect Digital.
I'm not entirely sure why that may be, but it does figure prominently in the product information on the Samsung product site.

New monitor not recieving signal via DVI, ok via VGA

Hello,
I have one of the original minis (1.25 GHz, 512 MB, etc) purchased back in early 2005. Until now I've been using an old CRT display connected via VGA. This past weekend I purchased a new 20" AOC LCD monitor from Costco. I attached it with the supplied VGA cable and it worked great. The next day I picked up a DVI cable, attached it and after a minute or two the monitor found the signal and displayed a beautiful image. After five minutes the monitor lost the signal and I haven't been able to get it back since. I exchanged the DVI cable for a new one, but still can't get a pic displayed. The monitor itself is self switching. It knows if the connection is via VGA or DVI.
What am I doing wrong? Could it be the mini? The monitor?
Please help.
Thanks
Dave

Yes, it is a display specific issue. If you look at this Apple spec page for the original mini and do a search on the word "coherent" it will take you to the part of the spec that deals with the issue.
http://support.apple.com/kb/SP65
Apple displays are not a problem because they have always used coherent receivers. But any other monitor is a roll of the dice, especially with the original mini. The newer mini with GMA950 graphics appears to be much less affected by this even though Apple left the wording in this part of the spec unchanged between the original G4 mini and the current Intel ones.

ATV2 on SD Projector via VGA?

I know VGA output cannot be adapted to HDMI without a converter box, but can it work the other way around? Obviously the picture wouldn't be 720p, but would I be able to display the ATV2 output with a HDMI to VGA adapter? And would the audio work? The projector can display 16:9 (4:3 native) if that matters. Thanks.

VGA doesn't carry sound, so you would need separate sound connection........... I assume you use one now since there is no mention of HDMI. The picture will transmit via VGA.

X3100 and 1080p via VGA

How can it be that the DELL Latitude D630 I got from work can output glorious 1080p on my Samsung FullHD LCD-TV via VGA, whereas my new Macbook 2.4 cannot? They both have the same video adapter (Intel GMA X3100)... Apple: can we still say "It just works" ?!?!

In other posts people often talk about installing softwares like SwitchresX. I do not like that... Why should I buy an additional software to make something as basic as connecting a laptop to an external monitor?
I have even read of people that have installed Vista on their Macbook and then got 1080p right away, while still not being able to get it in Mac OS with exactly the same equipment... I am a bit annoyed by this situation
Any help will be much appreciated!

Find monitor instance name , device name , resolution and frequency of multiple monitors (VGA and HDMI)

hi,
In my system multiple monitors are connected (VGA and HDMI). In need to know the
monitor instance name , device name , resolution and frequency of each monitor.. any solution?
i used wm class 'WmiMonitorConnectionParams' to determine Video output technology connection type and InstanceName.
But i didn't get the device name , resolution and frequency of each monitor.??
There are other wmi class like :
WmiMonitorBrightnessEvent
WmiMonitorConnectionParams
WmiMonitorRawEEdidV1Block
WmiMonitorListedFrequencyRanges
WmiMonitorDigitalVideoInputParams
WmiMonitorAnalogVideoInputParams
WmiMonitorID

WmiMonitorBrightness
WmiMonitorColorXYZinCIE
WmiMonitorSupportedDisplayFeatures
WmiMonitorBasicDisplayParams
Win32_VideoController
Win32_VideoConfiguration
Win32_VideoSettings Win32_DisplayControllerConfiguration
Win32_DisplayConfiguration
But unable to determine monitor having its corresponding values? please help me to find a solution .
is there any other method to get multi monitor details?
thank you

Hi sumith,
I read some documents about WmiMonitorConnectionParams class, it should be able to get the video putput technology by the D3DKMDT_VIDEO_OUTPUT_TECHNOLOGY enumeration.
D3DKMDT_VIDEO_OUTPUT_TECHNOLOGY enumeration
So what happens when you are using WmiMonitorConnectionParams class? What prevent you? Anyway, please see a example of using WmiMonitorConnectionParams class, maybe you could get some hints on it.

Sanyo 26" HD LCD DP26640 - digital via VGA?

I own a Sanyo 26" DP26640 that I've used with a Mac Mini (HDMI to HDMI) for almost 2 years. One of the HDMI ports has become dislodged from the inside and I'm exploring using the VGA port.
I've found several cables (HDMI to VGA and Thunderbolt to VGA), but they all indicate that they will only work if the TV supports digital output via the VGA port.
Does anyone know if this TV supports digital output via the VGA port? Thanks in advance.
