A: no signal input from input a - help

That message is coming from your monitor itself I believe and not from the computer.

Its saying that there is no video signal, which idicates that the computer has probably not even booted up?

Is the computer actually booting (keyboard lights flash, HDD light flicking) after you power it on?

Windows automatically updated last night before shutting down. When I turned on the computer this morning, the HP w2207h monitor was not functioning properly. Each time I rebooted, I received the message "HDMI Input: No Input Signal" before the monitor went to sleep.

I do not believe it is a problem with the sleep and display settings as I have dual monitors and the EN9910 is functioning properly; both are set to NEVER anyway. Further, I have plugged our SONY television into the HDMI port and it works just fine.

I have also plugged the monitor into another computer, using the same cable, and both worked just fine. The hp monitor also functions in the utility mode. Problem seems to exist only when Starting Windows.

This has happened once before with a Windows Update, but I don't recall the solution.

Please help.

Hello and welcome aspen can you just make sure the driver for that monitor is ok.

Software & Driver Downloads HP w2207h 22 inch LCD Monitor | HP? Support

But mate I also think you may have answered it yourself in another way. Can you remember when this started happening? If so system restore back to before that date.

Then it is just a matter of downloading any updates if this is what is - one or two at a time until you find which one is the culprit. Make a not of that one and each time it comes up untick it to download / install.

I have an HP Pavilion A6421.uk computer with an HP w2007v monitor. (The OS is Windows Vista).I've been getting the message "VGA Input - No Input Signal" and the monitor appears to be in sleep mode permanently. I've checked all the connections, cables etc and I have also connected the monitor to an old computer, where it worked fine. I'm guessing I need a new graphics card but don't know how to go about changing it. I have
opened up the box and cleaned it all out, but am not sure what to do now.

Could I take out the graphics card from the old computer and put it in the new one? The old computer is a Dell Dimension 5000 (Windows XP).
Or would it be an option to swap hard drives? (I urgently need to access my work but the old computer got a virus and doesn't work properly).I don't know the first thing about hardware really, so wondered what any of you would recommend I do:
1. Just buy a new graphics card and replace the old one - in which case, what would I buy?
2. Put the graphics card from the old machine into the new one. How do I do this and does anyone have any diagrams?
3. Swap the hard drives so that I use the old box with the new monitor. (this is probably a stupid idea, but who knows).

Please help!!

A:VGA Input - No Input Signal - New Graphics Card?

Hello, I have a pretty old CRT monitor hooked up to a computer which has a P4 3.2GHz, 1GB RAM, 256MB Geforce FX5500 video card, and is running Windows XP Professional. All had been working fine until recently, now when I turn the computer on it comes up with No Signal Input on the monitor. I opened the computer checked that the video card was still in properly, tried disconnecting it and reconnecting both the video card from the motherboard and the cable to and from the video card. I also tried to put it on the inbuilt video card that's on the motherboard and same result. I know its not the monitor or the monitor cables, because I plugged it into my laptop and it worked fine. So I don't know what it might be. If anyone can help that would be great.

Since my husband is an over-the-road trucker, he doesn't need access to his computer often. Therefore, I used it for a couple of school projects this past semester. I removed his hard drive and put a different one in to install Linux and do some other Linux-related projects.

Anyway, I just finished the semester, so I went to switch the hard drive back so that my husband could use his computer when he's back for a few days this weekend. I turned the computer's power on and saw all of the usual starting-up stuff. I even saw the desktop icons, etc., come up. I left the room briefly. When I came back, the screen was black. I pressed the power button on the monitor twice and then saw this message: RGB No Input Signal.

What exactly is that all about? It was working less than two minutes before, when I'd left the room. . .

I appreciate any suggestions you might have. Thanks!


A:RGB No Input Signal?!?

It suggests one of 2 things to me:

1, the monitor has slipped into some weird RGB input mode (look on the back of the monitor, see if you can see any places for component or RGB cables to plug in to).

Or 2, the video card on the machine has gone bad, or windows has crapped out on you...and an easy test for that would be to replace the linux drive and see if it runs ok then.

my pc takes to long to start, and when it starts, I always get a message saying ( no input signal ) .
Have I got a problem ?

Read other answers

Ok, I have this issue that I am going to guess is related to my video card but would liek some input from some more advanced people.

When I boot the pc I see the bios mfg screen and then it happens. The next thing I see on my screen is "No signal input" At other times, like as I was typing this, after the pc had been on only about 7 minutes, the monitor will show "No signal input"

What has me a little confused is this. I use a program called teamspeak, which allows me to talk with my gaming friends. When I get the no signal input and the screen goes blank, I cannot continue to talk to my friend and I cannot hear him either. If this was solely a video card issue wouldn't I still be able to talk and hear?

I have tried another monitor and unfortunately this MB does not have on board video.

Thank you

A:No Signal input

Double check all of the connections and that the Graphics card is seated fully in its slot.
If trying another monitor try another cable to eliminate if the cable or connectors have become faulty.
Ensure you are using the native settings of the monitor, or even try it with reduced resolution to see if that makes a difference. If using DVI try a VGA cable if you can.
If you can try a different PSU as well.

When I first start my computer I get a message in a small green box "no signal input, check video cable". It sometimes takes 15-20 minutes before I can get into my desk top?

A:No signal input

That message is being generated by your monitor. It is telling you that there is no signal coming from your video card and PC. You would get the same message if you disconnected the video cable.

So what is going on with your video card? That is the question.

The fact that it eventually comes on is curious. That suggests to me that there is a driver error or driver conflict going on and it is taking 20 minutes for Windows to resolve it. But it could be several other things too.

Is there any other information you can give us regarding the behavior. Any error messages? Problem devices in Device Manager? Any other unusual behaviors?

Let us know.

So... I have HP dc7700cmd tower and an Acer x193wbd monitor running xp that has an ATI Radeon x300/x550/x1050 (rv370), i just got this computer (and 2 more that are almost identical) at a computer sale at school (I've had the monitor for a few years and haven't had a problem yet (minus this)).

I turn the computer on, then the monitor (or vice versa), everything is fine. After the computer boots, if I turn off the monitor, then turn it back on, it says "No Input Signal" and to get it to come back on, I have to leave the monitor on, unplug the dvi cable, and plug it back in, and every thing is fine.

I just tried the monitor on another computer, it works fine... I tried a different monitor on this computer, it works fine too... it's something about this combination that something doesn't like.

Hey guys, can somebody give me an idea what is wrong with my desktop?

This was built/assembled in 2010. Everything works fine until I got the No input signal on monitor recently. Replaced my old graphic card "MSI GeForce GTS 250 N250GTS Twin Frozr 512MB 256-Bit GDDR3" with "EVGA GeForce GT 610 2048MB GDDR3." Computer turn on fine with display. Went to manufacturer's website to install latest driver. Selected Win7's and didn't bother to uninstall old driver since it's NVIDIA -> NVIDIA?

Everything was working (almost) perfectly the other day. Upgraded from window 7 to a Win10. Did a clean reset, so there was a lot of restarting. During 1 or 2 restart, there is a black screen for a minute but the mouse arrow is still visible. Everything then seems normal.

Now I'm getting "No input signal" again. Did I get a defective graphic card? because I haven't re-update to latest Win10 driver? or is something wrong with my mobo?
Here's my computer's spec:

- Mobo: EVGA P55 LE 123-LF-E653-KR LGA1156 Intel P55 ATX Intel
- RAIDMAX SMILODON Case With 500W Power Supply
- (current) GPU: EVGA GeForce GT 610 2048MB GDDR3
- CPU: Intel Core i3-530
- memory: CORSAIR XMS3 4GB (2 x 2GB) 240-Pin DDR3 SDRAM DDR3 1600
- HDD: SAMSUNG Spinpoint F3 HD502HJ/ST500DM005 500GB 7200 RPM 16MB Cache


A:No Signal Input

HI and welcome to TSG.

What is the exact make and model of the PSU? I am assuming it is probably a cheap unit if it came in the case, and at 5 years old and a GPU upgrade it is probably at the end of its life.

NVidia driver packages are fairly generic but it is good practice to uninstall / reinstall for a new GPU.

I assume you 're using a compaq deskpro.
Two things:
1) If after you boot you hear one short and two long beeps , that means is a memory problem. Try switching the memory, clearing the cmos and removing all memories and using a different one.

2) Try changing the video card, deskpro ep ussualy comes with this problem.

3) If nothing works I will say is the system board. Are you using any power surge??

Please post back.

Hi i have a AMD Phenom(tm) II X6 1055T CPU with 4 gig RAM and a ATI Radeon HD 5700 series Graphics card and for some reason the thing just sort of shuts down the screen mouse and keyboard. It just comes up with message: (no signal input check video cable) and the screen goes black and mouse and keyborad is down to but the PC is still running.

You have to press the on button to restart it. Can any body help me with this as I have been trying lots of thing and nothing is working. There is no sign that the graphics card is getting to hot or the cpu. I also have put it on standby for nights, which seemed to help but its doing the same thing again.

It does not matter what you do playing game or just browsing the internet it does the same thing.

Ps: there are 2 of the exact same pc in the house and they are both doing the same thing.

Please help me....

Thank you

A:No signal input

I would suggest checking your video cable unplug it and check the pins of they are ok plug it back in and make sure it is in properly and snug.

Then next thing to is check the video card make sure it is seated properly.

Make sure you have the video cable connected to the right connector you will have one that came with your motherboard and one to your graphics card make sure it is in the right one.

Hello Tech support forum,
A friend of mine has a problem with her pc: when she starts the pc, after the normal bios messages and the Windows XP rolling bar screen, there is in a few moment of a blue screen with text (unreadable, because it disapears again) and then 2 beeps and finishing with the text "No input signal".
This happens in all the options you see, when pressing [F2]: Start in Save mode (with or without networking), Last working configuration and Start Windows).
I was able to come in a Dos prompt and to look on the C:\ drive with a DOS-CD.

According to her, it started to happen when she had pressed a button to install something (windows update ???), but she doesn't know what it was.

How can I find out what the problem is and how to solve it?


A:No input signal

I would start by testing the monitor. Try connecting it to another PC and see if it works properly or not. If it works, then the issue is likely with the PC. Since the problem appears to also occur in Safe Mode, there could be an actual hardware problem or Windows is corrupted and needs to be repaired/reinstalled.

Hi Guys, Had a phone call from my Brother who has a HP screen  model 1740 connected to his computer with a cable, which has started displaying sometimes a message " No Input Signal" then turns its self off ( the screen).
If he waits sometimes the screen comes back on, most times he close down the computer waits a while and turns the computer back on and no problem.....then same problem, " No Input Signal"
He has checked and all cables appear connected okay.
Any suggestions please?

A:No Input Signal

You need to take steps to prove whether the problem lies in the monitor or the computer. Usually the simplest way is to connect the monitor to another computer, and see if the same thing happens. It's also possible but probably less likely, that the signal cable is faulty, same principle applies - if the problem only ever occurs when that cable is being used, and not with another, it's faulty.
Just as an oddity, some video drivers have the option to reduce the signal amplitude to 0.7V instead of 1V - it would be strange for this to change, but if the problem proves to lie in the computer, it's one thing to check. Some monitors can tend to detect no signal at times with the lower setting.

Hi, so here is the problem, my computer worked fine for the past 5 months thought i recently moved and left the computer in my new home unused for about 2 wks. Though now when i connect the computer completly i get "no input signal" on the monitor. The computer works fine when I check it inside and such, and the monitor works fine. Perhaps on the long drive moving it, the hard drive got bumped too much and messed up? That is the main thing im wondering may be wrong, though shouldnt i have received a hard drive error instead of nothing at all.... Any help would be great!, thanks.

A:No Input Signal

Make sure that the CPU heatsink and fan hasn't come loose and check all the internal power supply connections. Check to see that the video card is seated fully and make sure you are not connecting the monitor to the on-board video connector instead of the video card connector... Don't laugh, I have seen some people do this!

A:No Signal Input

Hello preciousgreeneye, and welcome to TSG Forums....

My first thought was to check device manager to see the status of your Display Adapter drivers, but obviously you cannot do so because you cannot get a video display after booting. You might try booting in Safe mode and see what happens there. In case you don't know how, just begin tapping the F8 key after you press the power switch. Hopefully, you will get a black screen with various options listed. Using the arrow keys, highlight the Safe Mode option and hit enter. Post back what happens.

The only other thing I can suggest is to open the tower and, if you have one, remove your video card then reseat it. Possibly a faulty connection. Be sure to ground your self by touching the chassis with your bare hand before touching any of the electronics inside. Doing so allows any static build up in your body to discharge.

When I turn my PC on I get the message "No Input Signal" on the monitor. Also, I don't hear the normal boot up sounds from my PC such as the beeps, etc. Could my BIOS or Motherboard be dead? Or what?
TIA, Tkd2frek1

A:No Input Signal

Hi Tkd2frek1 and welcome to TSG.

There is probably not going to be an easy answer to this one, but don't panic just yet.
The fast that you are not hearing start-up sounds from you PC suggests its not a monitor fault (try to connect it to another PC to confirm this).
Your first line of attack should be to ensure that all leads and connections are firmly in place.

Start with the external ones, just for good measure, particularly between Monitor and CPU, but then progress, if necessary, to the internals.
Check all the add-in boards, particularly the video card, are tight and firmly set in their sockets. Remove and re-seat them if necessary. The video card is the first prime suspect.
Check your memory chips in the same way.
Try a power-up at various stages through this process to see if any changes occur - please don't eloctrocute yourself so take ALL the usual precautions, particularly grounding the chassis after each power off.

Last in the line is going to be the motherboard. If you have got to this stage - and it might not happen - and found no cure, it could mean a board failure and replacement might be your only option.

HOWEVER, do not jump to conclusions and take one step at a time. Wait a while to see what others have to say on this subject and, in any case, keep posting back with any problems or anxieties you might have.

I often tend to suspect the graphic cards in such a situation, but it could really be anything. We need more information to troubleshoot that.

Really having some wonk issues with these last two Lenovo products I've bought. It's nuts. Latest weird thing that's happening seems to be some sort of unintended input. Occasionally, I've had the focus repeatedly stolen from an input field I was typing in. I have to click on the field several times, only to have it taken away again, like the mouse is clicking elsewhere. (I've been having issues with clicking things accidentally firing double-clicks--maybe my mouse buttons are faulty? Both the X1E I returned and this X1C have done that.) The other strange thing that's happening is that in iTunes, if I pause my music, it will resume itself 5 seconds later, like the play button some keyboards have was pressed. But this keyboard doesn't even have that, as far as I can tell. It feels like my computer is inventing input. It's maddening.  Any clues? My opinion of Lenovo products has sharply dropped these last couple months.

Sorry for the silly question, but I am really lost with Windows 8. Did a quick search, but nothing came up (Keyword will only result in how to set input in Win8, not the problem presented here).
Here is the issue.

The short version of the question is how do I move the #@#[email protected]%$#^%$ (display gibberish somehow, boxed in red below) input method above Microsoft Pinyin, while keeping English as my default Display language and Input language.
Longer version here:
I use English and Chinese input, but the default MS Chinese input is "inconvenient", so I installed another input software for Chinese input (the gibberish above, or lets call it method ABCD).
The order I want is English as my default Input method and display, while ABCD as my default Chinese input (when I hit Alt + Shift, should switch from English to ABCD). However, since I can't get ABCD above MS-PinYing, when I Alt+Shift it auto switch to MS-Pinyin, not ABCD (Manually switch from MS to ABCD gets annoying).
In WinXp/Win7 I only need to manually switch to ABCD once, and the system remembers it, but Win8 for some reason automotcally load the language list on every start up =/
Also in WinXp/Win7, I can delete MS-PinYin while keeping ABCD (so I only have English and ABCD), but Win8 doesn't allow me to do that as I must have MS-input or the second line (highlight in green) in language perference doesn't even appear.  
There are some additional points/details.

Hi there @145755, I hope you find your Support Forum experience a positive one!  It is a great place to find the help you need, from other users, HP experts, and other support personnel.  I understand that you have changed a setting on your computer and now the display is not working.  I am happy to give you a hand with this. Please post the full product number for your computer. See the following, if you need help with that information.  HP Desktop PCs - How Do I Find My Model Number, Serial Number or Product Number? I would suggest you try to start your computer in Safe mode to load basic screen settings. See this document: HP PCs - Windows Safe Mode (Windows 10, 8). As you are unable to see the display properly at this time you will need to follow the process described for "Entering Safe Mode without access to Startup Settings".  If you are able to get in, then make the needed adjustments to your display settings, then restart your system normally to see if the display will come up properly. If not try a different screen resolution. Please let me know whether that works for you, and if it does resolve your issue, please mark this post as a solution. Kudos would also be appreciated.

I have a Dell D610 laptop w/ XP Pro SP2... or had.

I have a corrupted registry entry hosing the keyboard input. The mouse works fine up until the point when I kit the first key on the keyboard when under the Graphical Windows interface. After I hit any key, the mouse freezes as well. This happens if I use the laptop keyboard or an external keyboard connected to a PS2 jack.

I have performed hours of troubleshooting and it is not the keyboard hardware. Keyboard input works during all non-graphical UI (BIOS, Recovery Console, etc.). I even removed the drive and plugged it in to another computer. I made a copy of the WINNT\system32\config files (sam, default, security, system, software) and replaced them w/ a copy of these files from WINNT\repair. The computer boots to Graphical Windows and I am able to type in this session just fine.

How can I "erase" the keyboard driver corruption in the registry (or perhaps a corrupted driver file or set of files)? The problem is that I can't boot the system to a point where I can edit the "corrupted" keyboard entries. I can't use the Recovery Console because I don't have the Administrator password. So I tried to install SP3 from a bootable CD. The minute it asks me to type in the Product Key (a graphical dialog box), input is frozen a the first keystroke (even a key like Caps Lock). Can I actually edit the registry that resides on the boot drive while it is connected to another computer? Any other suggest... Read more

I have a Dell Dimension 5150 wih XP Home SP3.
After an IT shop reload of XP Home the unit goes through a routine start-up and black screens"INPUT SIGNAL OUT OF RANGE" after the Windows XP flag appears. Of course nothing moves after that.
The Dell will start in the SAFE mode.
I have attached both a CRT monitor and a Hanspree HF237 flat screen with identical results.
The Control Panel Display settings have no effect in either resolution or color bit sizing.
Is this an output frequency issue? But, why does the unit work in SAFE mode.
It appears that the OS may have been changed by the SP3.
The Dell tech guys are still chewing on this one. And may continue to for a while.
Thank you in advance for your leadership on this.


FWIW: Out of range messages...usually are monitor situations.

I'd try uninstalling the video drivers in safe mode, then rebooting.

I've already royally messed up my computer (see this thread http://forums.techguy.org/showthread.php?p=2395469#post2395469 )

And now, for some reason, whenever I turn my computer on, there's no signal. All the wires are connected and I've tested two different working monitors, so I know that there's nothing wrong with the monitors.

My gfx card is a Nvidia GeForce FX 5200 made by EVGA. Please help

Hi all, yesterday i bought a pc from a friend i saw the pc working at his house on a 40" LCD HD TV, When i got the computer back home i hooked it up to my old 17" CRT monitor plugged into a DVI connector then the DVI connector plugged into a HD connector then into the HD slot at the back my computer, when i turned the computer on the monitor said, RGB no input signal, for some reason i thought that was because my old CRT monitor was just TOO old so i borrowed a 17" LCD monitor and tried it using that but i still get the same error. So now i've hooked it up to my HD TV using a HD cable and its working fine but i cant keep it on the TV forever, i'd like it to work on either of my monitors (neither are HD)

I've looked around on the internet searching the error i cant find many answers other than, check the cables.. which i have done and, the graphics card is broken but it isnt i've just been playing COD:MW2 on it, also read that it could be the resolution, it could be set way too high to be used on a small monitor. I've tried to change the resolution on my TV to the smallest then switch to my monitor but i still get the same problem. so does anyone have any other ideas i could try

Input type for both monitors are VGA. output for the pc is HDMI only, i have a dvi connector, i put my brothers graphics card in my pc nvidia 8600gt but i still got the same error with both monitors.

heres the motherboard i have.. http://www.play.com/PC/PCs/-/... Read more

K please someone help me on this: recently when I have tried to adjust my display settings (on control panel display and settings and screen resolution) the lowest which I am used to doing, my screen has gone black when I have applied it which is normal but then it comes up "input signal out of range" this is the first time it has ever done this for me when applying another screen resolution. Usually its never a problem and because of this I cannot seem to run any games, my screen just flashes briefly when I open them and nothing happens. I have I done a windows reinstall but it did not change anything.

Can anyone help me out here? anyone else suddenly gotten this when they have messed around with display screen resolutions? what on earth is it and how can I rectify it. Thanks.

Apologies if this isnt the right place to post this, but I have a bit of a strange problem

playing star wars the old republic, when i try to start up the game in full screen mode, the monitor goes back and says "input signal out of range". from what I understand thats the game trying to run at a resolution the monitor doesn't support. went and edited the config file for star wars, get the game going in windowed mode, only now there is tremendous lag, from what i can tell its like a combination of framerate lag and network lag

was able to play the beta client (which is literally the same client they used at release) full screen just fine, no issues whatsoever, everything ran smooth

changing the resolution and refresh rate in game didn't really help anything, graphics are as low as they can be, etc

anyone have any suggestions?

Hello and welcome to Techspot.

Go HERE and read my post. A message for all newcomers.

Did your computer run ok before you took the psu out?

Make sure you have connected everything properly.

If this doesn`t work then maybe you need a new psu, or mobo.

When I turn on my computer, an HP pavilion m7690y running XP, I get a black screen with the message, "Input signal out of range Change settings to 1280x1024 60hz"
I've tried holding down f8, when I turn it back on, but no luck.

I should note this was preceded by me installing sophos, then starting it to clean what was already probably a very infected system (spybot found click.gift load, but couldn't get rid of it). Sophos found tdl3mem-b I stopped the cleaning, then right clicked it to clean a few things. It found something on what was a changed windows defender, however, The very last function I did was was my hp tv-tuner interface, and thats when it froze. I turned it off, and since then, no luck even getting into windows.
I wonder if I'm completely screwed. (at least data files we're all backed up on an external hard drive)

Any help is much appreciated. Thanks

Did you download and run Wise Registry cleaner by SOPHOS?

This is not a suggestion, only a question. The staff here at BC does not endorse the use of registry cleaners as the tradeoff isn't worth the use of these programs. More importantly, if you make an error while running one of these programs you can make changes to the registry which can result in rendering your computer inoperable.

I tried a little psychology. wanted to fix a room up in my house for an office and put my sony vio in there but knew my husband would gawk so I decided to build him a computer he could not wait to get on and the catch was that he had to finish my office so we can swap computers and he can use his new toy. no office, no place for his computer, so no playing. Thats how you have to deal with some men. :rolleyes: LOL. well he is anxious all right but I have screwed up. :blush: I should explain that all he uses the computer is for is to play tumblebugs (for hours), go to NFL.com, download and burn music, check his spam that he calls email, and check out parts for his car on eBay, So I did not have to spend a lot of money, just provide an asthetically pleasing puter.

The motherboard was a Soyo Dragon plus with an AMD Athalon 266/1000 processor, GeForce MX4000 video card (the slmx4000 version which the guy says is a 1.3v but I can not verify that), 256mb DDR, a DVD burner, CD Burner and a Westinghouse, flat panel LCD monitor. When I put it all together the lights on the case did not work and there was no input signal to the monitor. I had set the jumpers for the bus speed at 100 with a multiplier of 10. heard a long beep, long beep, long beep. changed the multiplier to 133/7.5 and still got no signal but no beeps either. changed the settings to 200/5 and the beeps went away but no improvement on the post not going through.

Ok, today I installed Windows XP to my computer. Before, I had Windows Media Edition XP, something like that. Our computer was giving up problems and someone suggested we just start over and reinstall XP and now we have XP professional. Now, when it loaded up, the resolution is at 800x600. Originally, the computer was at 1280 x 1024 so I know for a fact it's capable of going to that resolution. But when I try to change it, it says "Input status out of reach". I notice, many drivers need to be updated, but I cannot find my particular video driver. It's ATI Radeon, the video card/monitor and I cannot find it... I think this is the problem. Can somebody help me please? Also this is my second time installing it today. The first time, I kept trying to change the resolution and the screen just STUCK to the error floating and would shut off the monitor. I tried putting the video cable in and out again but nothing. Thanks for reading, help appreciated!Also, this is my computer specs.http://h20000.www2.hp.com/bizsupport/TechS...ectID=c00587142

When I start my computer the monitor power comes on fine it says auto adjusting. Then I see some activity like some dos words when the computer is booting up. Then it goes to auto adjusting again, then it says "No Input Signal". Then it goes to sleep. I tried rebooting many times I don't use a graphics card I use onboard video. Everything is connected like its suppose to be it has two options VGA and DVI. I haven't tried the DVI connection yet, but even so I would like to have VGA for right now I do not have DVI abilities on my computer. Of coarse because the normal standard video output onboard motherboards is most likely VGA. I would like help with this please!!! 

A:HP w1907 "No Input Signal"

Check the source of the monitor from the Front OSD Menu buttons. I know with my monitor, it sometimes goes off from what I am using and displays "No Input", changing the source brings it back. Cheers,
