VGA No Signal

What does it mean when i get the message that says "VGA No Signal"? Do I need to replace something?
This question was solved.
View Solution.

It means that the monitor isn't getting a VGA (blue analog video cable) signal from the pc. This is normal if you use other video cables such the DVI (white) and HDMI (black) cables. In this case VGA won't be active.
I would check the video cable from the pc tower to the monitor. If it's the blue VGA cable then make sure it's plugged in correctly at both ends.
Do you get any video display when you turn on the lcd and pc?

VGA output signal is present but my VGA monitor won't display it --- why?

When I connect the iPad to a Samsung SyncMaster 570STFT display (with the Apple iPad Dock Connector to VGA Adapter) and try to play a movie, the audio plays and the image on the iPad is not updated (which I would expect, since it's supposed to be playing on the external VGA), but the monitor reports "Video mode not supported" (which is what it says when the display resolution is out of range).
I've verified that the monitor works fine at iPad resolution (by plugging it into a Mac Mini and confirming that it is operating at 1024x768).
Is there something unusual about the iPad's VGA output that is incompatible with some displays? Has anybody else run into this problem?

Scan rate and frame rate are different item. VGA is analogue and is based on CRT in which the electron gun scan the phosphors on the screen. Frame rate, as you seem to know, is how many screens there are per second.
If you look at the properties of your video what does it say. Does it play on your iPad?
The tech specs for the iPad say the following. Note that it says:
"640 by 480 pixels" for MPEG-4
TV and video
Support for 1024 by 768 pixels with Dock Connector to VGA Adapter; 576p and 480p with Apple Component AV Cable; 576i and 480i with Apple Composite AV Cable
H.264 video up to 720p, 30 frames per second, Main Profile level 3.1 with AAC-LC audio up to 160 Kbps per channel, 48kHz, stereo audio in .m4v, .mp4, and .mov file formats; MPEG-4 video, up to 2.5 Mbps, 640 by 480 pixels, 30 frames per second, Simple Profile with AAC-LC audio up to 160 Kbps, 48kHz, stereo audio in .m4v, .mp4, and .mov file formats; Motion JPEG (M-JPEG) up to 35 Mbps, 1280 by 720 pixels, 30 frames per second, audio in ulaw, PCM stereo audio in .avi file format

No vga/dvi signal , sends monitor into sleep mode even though I disabled sleep mode.

I have a HP Pavillion Media center PC system # RX883AA-ABA with a NVIDIA GeForce 7350 LE graphics card. The monitor is a HP w1907, it is connected to the desktop vga(monitor end) and dvi (desktop end) due to there is no vga port on the desktop.
It started randomly saying no siganl and monitor going into sleep mode. Now that is all I get. I know the monitor works because I hooked it up to my sons computer. I even did all the updates to all drivers on my system before it quit on me. So after the process of elimination it can only be video card.
So, my question is, does anyone have a suggestion that I may have missed? And if it is the video card, where can I get a replacement and how do I replace it?
I need to get the desktop up and running optimally before my 4 year old starts cyber school.
PLEASE HELP!!!!

In checking the SPEC page for that model, I see that PC does have onboard graphics. Since it does, you can easily check and even use the PC by removing the graphics card and connecting the monitor to the VGA out from the onboard graphics. Once the step is done and still it works, just not with the graphics card, then replace the card. With only a 300W power supply, not much of a card can be installed. It would appear sometrhing similar to THIS would be compatible.

Samsung P400 Projector not working with mini-DVI to VGA

I've never had so many hardware problems with a computer before... sigh.
Why they labeled a 100-240v 50/60Hz power supply with a sticker that says 100-120V 60Hz is beyond me (Sony did the same with their original US PS3s but that's another tale). Anyways, here's my issue.
I just bought the new 2009 Mac Mini along with a Samsung P400 Projector. This is one of those new pocket type with the LED bulbs.
The Samsung P400 has a native resolution of 800x600 60Hz and can accept analog composite or VGA video signals.
So, in my blind belief that Apple would sell me the correct adapter to go from mini-DVI to VGA, I went and I purchased said adapter. And lo and behold, it doesn't work.
Now, I'm a computer guy, I've built my own systems. I know the difference between analog and digital, DVI-I and DVI-D, etc. So, when I read the specs on my merchandise and they all use the same connection labels DVI, mini-DVI, VGA, etc. it really irks me to find that they are all incompatible with each other. I don't understand how this is supposed to help the customer. It's ridiculous. Apple is supposed to be user friendly but this is downright evil.
But, I've invested over a thousand dollars in this venture and I want it to work. *SO, before I go and run out and spend another $30 on a mini-DisplayPort to VGA adapter, can anyone tell me if it will work with my projector????*

Thanks for your help.
But I had just figured out a solution today. I guessed that the resolution wasn't holding when I switched monitors so I went and picked up a mini-DisplayPort adapter to run the monitor along side the projector at the same. This way I could see what was going on.
Turns out that projector was automatically being set to 1600x1200. I changed the resolution to a lower one and it was fixed. Of course, when I tried to switch back to the mini-DVI to VGA adapter, OS X forgot the settings again and I had to redo everything.
I'll try your solution as well but for now, I think I am okay. I will just use the mini-DisplayPort to VGA and not unplug the projector unless I really have to.
I'll test your solution just in case I need to reset the resolution again.
Thanks once again!!!

Pavilion h8-1128 w/Radion HD 6750: VGA disables DVI!!!

I need to run 2 SAMSUNG monitors of of my h8-1128 that came with an Eyefinity Radion HD6570.
Operating system is Windows 7 Home Premium 64bit.
Both monitors support DVI and VGA inputs. The HD6570 has DVI-I, HDMI, and DisplayPort outputs, and a DVI to VGA dongle.
After looking into cables a bit, I located this cable:
StarTech.com DVIVGAYMM6 6-Feet DVI-I Male to DVI-D Male and HD15 VGA Male Video Splitter Cable
by StarTech
Product Features
Connect a DVI-D and a VGA Monitor simultaneously to a single DVI-I video source
Easy to use and install
Backed by StarTech.com's lifetime warranty
DVI-I Male connector to DVI-D Male and HD15 VGA Male connectors
Connector A 1x DVI-I (29 pin) Male, Connector B 1x VGA (15 pin; High Density D-Sub) Male, 1x DVI-D (25 pin) Male
That appeared to do what I santed by splitting the 6570's DVI connector's digital and analog signals into appropriate connectors.
I connected the cable to the graphics card, then connected the DVI-D male connector to the 1st monitor and verified operation. Next I connected the VGA connector to the 2nd monitor and turned it on. Immediately the DVI connected monitor's screen went black, altho the monitor did not indicate signal loss, and the VGA connected monitor came on & displayed the desktop as the primary monitor!
The screen resolution window only showed the VGA connected monitor as a generic plugNplay monitor. When that same monitor was connected using the DVI->VGA dongle that came with the system the monitor is correctly identified as a SAMSUNG 245BW.
I could not get the screen resolution window to recognize the DVI connected monitor until I disconnected the VGA cable from it's monitor.
Is this expected operation? I thought the VGA analog signaling was independent of the DVI-D signaling?
This question was solved.
View Solution.

Use the DVI->VGA dongle on the 6570's DVI connector with a VGA cable to the monitor that's being shared with the CATV box, then either a HDMI to DVI cable, or a DisplayPort to DVI cable.
You are correct... that would be the way to do it.

VGA unplug, replug needs xrandr off, xrandr on since recently

Hello,
I need to plug and unplug my laptop several times a day to an external VGA beamer.
Before recently, I switched on the external VGA (DP1) ONE time by:
xrandr --output eDP1 --mode 1366x768 --output DP1 --mode 1366x768
and no matter how I pluged VGA in and out, the VGA output stayed active and usable.
But since recently, when I unplug VGA and plug it in again, there is no signal at the VGA output. I have to do
xrandr --output eDP1 --mode 1366x768 --output DP1 --off && xrandr --output eDP1 --mode 1366x768 --output DP1 --mode 1366x768
in order to get the VGA output working again.
So I would like to have it still the old way, with VGA output staying on, no matter how I unplug and plug. How can I achieve that?

Try dropping the --brightness switch, and set it with xbacklight instead From man xrandr:
--brightness brightness
Multiply the gamma values on the crtc currently
attached to the output to specified floating value.
Useful for overly bright or overly dim outputs. How‐
ever, this is a software only modification, if your
hardware has support to actually change the bright‐
ness, you will probably prefer to use xbacklight.

Problems connecting my macbook pro to my samsung led Tv

Hi. I try to present some pictures and videos by connecting my macbook pro to my samsung led Tv but my mac doesn't recognize the Tv (or it could be that my TV doesn't recognize the mac). What should I do?

I have problems too with some projectors and the DVI--VGA adapter that came with my MBP. The projector is recognized by the computer, but does not show any signal.
With the help of Stéphane Madrau, who has written the excellent tool SwitchResX, I found out that the projector reports that it takes digital input when I connect the MacBook Pro, but analog when I connect it to my 12" PBG4. From the DDC information (collected with SwitchResX):
MacBook Pro, DVI--VGA:
Input signal & sync:
Digital
PBG4, miniDVI--VGA:
Input signal & sync:
Analog input with: 0.700V / 0.300V
Separate Sync
Composite Sync
Given that the VGA cable is analog only, I would think that the MBP tries (or rather, does) output digital signals only, which don't make it into the VGA cable. If I find a solution I will post it here.
The clue was that the computer did not report any vertical scan frequencies for the external display, while it did so for a projector that worked.

Power Mac Mirror Door DVI or ADC to SINGLE RCA VIDEO OUT to a TV...adapter?

I have a Mirror Door G4 tower that I would like to use as a media center, with an old(er) Magnavox 19" television that only has the single yellow VIDEO IN jack, and the red and white audio L and R. Is there a converter cable that is similar to the one I used to use with my old G4 Powerbook which took the mini DVI and turned it into either composite video out? (I think it was Mini DVI, maybe ADC, whatever that little square video out on the Powerbook G4). I am prepared for low-res results, mostly just want to look at the itunes window and occasionally view utube clips or DVDs.
Also, does the G4 take the original Airport card (not the extreme), and if so does it need a separate antenna the way some G5s do?
And finally should I get good results with a Bluetooth dongle plugged into a USB port on the rear of the G4 when connecting a white Apple wireless keyboard?
Some of these answers will of course sort themselves out with experimentation, but any tips or experience in doing these things would be greatly appreciated.
Thanks, m.

I expect the weasel-words in Apple's description are there to be sure that whatever Video card you choose, the card does actually provide the signals needed. These are the VGA-equivalent signals around the Bar at one end of the connector. That gets you Red, Blue, Green+Luminosity, H-Sync and V-Sync. Those signals in combination are all that is needed to build S-Video or Yellow-RCA composite video On-the-Fly (not buffered).
The signals can be sliced and diced to get slightly different versions of Analog Video using adapters built around the SKART interface. There is a cheap one-chip wonder converter used in lots of converters, also loosely called SKART.
http://en.wikipedia.org/wiki/SKART
This does NOT do conversion to Digital Video, DVI, or HDMI when starting from VGA. That kind of converter has memory and scanning hardware that pushes the cost up higher than the price of an display card.

Problems connecting my MacBook Pro to a video projector

I have a MacBook Pro. I have used it many times to connect to a video projector and give presentations in my classroom. Lately, it is hit or miss concerning whether the laptop will give a signal to the computer. I can't figure out what I am doing wrong. I have followed the instructions in the MacBook guide.(Start with projector and laptop off, connect, turn on, etc. )
I am using the DVI to VGA adapter. I have also tried to use the function keys and manually tried to get it to detect displays. Can't think of what to do next. I gave up and hooked up a Windows computer and it worked.
Could it be the adapter? Does anyone have any ideas I can try? Thanks!

Apple 23 Cinema not working with nvidia 5200...help!!!

Hey all!
I have an Apple 23" Cinema that is not working with my Windows XP machine using an NVIDIA 5200 128meg graphics card. The montior, when booting Windows, just flashes its power light 3 times...goes off...then repeats the sequence.
So, I tried a Dell 2007WFP with the XP machine using the DVI port of the card. When booting, it seems like it's going to fire up the monitor (shows splash screen and Windows logo) but then goes blank when it hits the desktop.
Oddly enough, when I plug in my Apple 30" into the DVI port of the NVIDIA card, it works just great. No fuss or muss (other than a resolution change).
The 23" also works fine with my MacPro BTW so I know the monitor is golden.
Any takers on this one?
Thanks in advance!

Hi Talon, I just accidentally came across your thread. Maybe I can help. I own a 23-inch cinema HD display but mine is ADC and I have to run mine through an ADC to DVI adapter.
Anyways on to the discussion...
The nvidia 5200 is a rather old-ish card (or chipset). The feature set in these older cards are not necessarily symmetrically reciprocal (what?) throughout the feature set. In other words, the feature may work in one mode and not in the another mode...etc...
You may have seen these specs on your 5200 card/chipset:
+Dual RAMDACs (up to 400 MHz) for display resolutions up to and including 2048×1536 @ 85Hz+
and thought this would be great, my resolution is less than that @ 1920x1200 on my 23-inch cinema display. However I believe this may be referring only to the vga output signal and not the DVI. Read on...
Further down in the specs for the 5200 card/chipset you'll see:
+DVI support for compatibility with nextgeneration flat panel displays with resolutions up to and including 1600×1200+
Unfortunately, this is not enough resolution to power your 23-inch display at 1920x1200. Windows may even show the resolution 1920x1200 as available (if you're able to get to the screen) but what I think it's not telling you, it that in order for you to be able to use that resolution you'll need to switch to dual mode DVI, and the card does this automatically.
For example: 640x800 to 1600x1200 uses single mode DVI and anything above that (like our 23-inch cinema HD monitors @ 1920x1200) +using this particular card/chipset+ will be using dual mode DVI whether the monitor can support that mode or not. From my experience with my HD cinema it uses single mode DVI.
As someone said above your 23-inch is in *single mode DVI* and from my experience only accepts *single mode DVI input* from the graphics card.
From my understanding of the specs and your description of the delimma, I would suppose that you are able to get the 30 inch display to work because the 30 inch is a *dual mode DVI monitor* and your graphics card does work in dual DVI mode up to your 30-inch resolution but ONLY in dual DVI mode.
Here are the specs on it:
http://www.nvidia.com/page/pg_20040109440047.html
I hope this helps you out.
If you were to ask my recommendation, I'd go buy a new video card that has higher resolution on the single mode DVI output. I can tell you that my ATI 2600 HD Pro (AGP) (windows version, not mac only) has two DVI ports that are both dual mode DVI capable but also dumb down to single mode DVI signaling at high enough resolution to support our 23-inch cinema HD single mode DVI displays.
Good luck!

233 MHz G3 Compatibility with Sony SDM-X52 15" LCD Monitor

Trying to interface the subject items, the monitor recognizes the Mac's video output on its input #2, but shows the error "Scan Out of Range," and "Frequency 43.3 Khz/85 Hz." According to the Sony manual this means the horizontal scan frequency is 43.3 KHz, which is within the monitor's range, but the vertical frequency needs to be 56 - 75 Hz. The graphics card in the G3 is the original OEM ATI Rage II+, which Apple states "supports refresh rates up to 85 Hz." However, I haven't the slightest idea how to reduce that rate to between 56-75 Hz.
There is an adapter on the G3's monitor output which allegedly converts to a VGA/SVGA signal, and it does mate with a cable that is compatible with the Sony monitor. This adapter contains slide switches and a rotary dial, and a label on the bottom which identifies the characteristics for its various settings. The G3 was previously interfaced with a CRT monitor, and worked fine. The current settings on the adapter are for 640x480/800x600 resolution with vertical and horizontal sync signals active (these can be turned off but have not tried that).
The adapter has no manufacturer name or logo, only an icon of the Liberty Bell molded into its case.
Would anything I do to this adapter's settings change the vertical scan frequency?
(BTW, the monitor works perfectly on its DVI-D input #1 with my G5.)

Hi, Bill -
The reason I asked if you had another monitor, is that the initial settings (the ones used at the beginning of startup) for the monitor are stored in the Mac's PRAM. After the OS has loaded sufficiently for additional or other settings (if they are different than those in PRAM - not common, but possible, especially when switching from one OS to another) in the appropriate prefs file(s) to be read, those take over.
If you had a different monitor to use, you could use it to get the machine running, then use the Monitors control panel to reset the resolution and frequency to a combo acceptable to the monitor. Then shut down, swap monitors, and give it a try. When the machine is shut down, the applicable settings in the prefs files are transferred to and stored in PRAM, making them the initial governing settings at the next boot.
You might try a reset of PRAM (zapping the PRAM, in old lingo). Doing this should reset the settings in PRAM to the default ones, probably 480x600 @ 60Hz for your model. Later model G3s and G4s default to 600x800 @ 60Hz.

If that works initially, then immediately press the Shift key and keep it held down until the desktop has loaded. This will prevent the Monitors control panel (along with other control panels and non-critical extensions) from becoming active - and with a bit of luck will prevent the prefs file from being read.
If that works, then go into the Preferences folder in System Folder and trash the Display Preferences and Monitors Preferences files. Empty the Trash. Then try a normal restart.

Monitor keeps going to sleep

Hello there
I have a HP Pavilion Elite HPE-063uk Desktop PC, product number: VG251AA, serial number {Content Removed}, with Windows 7, my monitor keeps going to sleep and a message saying VGA NO SIGNAL comes up. The only way to awake it is by switching the pc off at the power button (the F2 or "half moon" button should awake it but does not) .
I have checked everything from the "Save Power settings (which is on off)" to Screen Saver (off as well) and done anything what I can find on the HP help and support, troubleshooting problems, testing this and that, even connected a different monitor and restored it to an earlier date, but I cannot solve the problem.
Please can you help. Thank you.

Hi vitolaterza,
Are you getting the no VGA signal after the computer goes to sleep? If so this is normal.
Turn off all sleep mode options; make sure everything is set to never sleep.
Check the cables on the back, you only need one video cable going to the monitor. Also go to hp.com and download the latest BIOS and Graphics driver.
Here is a link to download the drivers.
Let me know if this helps.

HP Pavilion p6240f Dual Monitor setup problems

My HP Pavilion p6240f desktop has two on board monitor conections. VGA and DVI. Can I connect two monitors to my computer? My operating system is windows 8. Only my VGA monitor is working. Only one monitor shows up in Device Manager.I also tried using detect in display settings. Please help

dighaysus,
Yes, your HP Pavilion p6240f Desktop Computer can support two monitors at the same time. One monitor must accept a VGA analog signal and the other monitor must accept a DVI-D (HDMI with adapter) digital signal.
Please provide the brand and models of the two monitors, so we can determine if you have a supported configuration.

No HDMI port

Two years before I buy G570 from Fry's. Today I need connect my computer to HDTV by HDMI output but alas there is no HDMI port . There is three side by side USB (one of them different appearance) , one RJ45 and one VGA connector at the left side. Between USB and RJ45 there is no HDMI connector.
İs it normal ?
Can I add a HDMI port ?
Thanks

hi Psawed,
If the system does not an HDMI port it means that a transcoder is not included in the Board and VGA Port cannot output a Digital Signal. Only analog.
What you'll need is an external Signal transcoder, From VGA analog signal to HDMI Digital Signal.
You'll need one of these VGA to HDMI Tanscoder.
Hope this helps,
Cheers!
