If I remove the HDMI cable I have chosen the Wiederhertellung, in which all data will be deleted. Can I monitor when he is plugged. Try it with only mouse, keyboard and monitor connected. Since that shows me version of the page of windows of 8.1.

Do not look at it with this one, it shows me: "No signal!". After I had selected this, the PC restarted. If the monitor is printed and printed (about 3-4 minutes each). My PC: connected via VGA?



Hi all,

Hello and welcome,

I think now I'll go here ... if it uninstalls drivers. (Nvidea was too lazy to do it manually.) Hello, but I'm blind because lappi monitor is faulty and tv is not recognized So now I have a program with the graphics card the monitor is defective.






Okay then ask or 'Graphics on board defective'. Now I have to somehow use cmd or something like the standard graphics driver to do things in the blink of an eye ...... Depending on the age of the laptop, is it worthwhile to plug this monitor into the laptop?

My monitor is a Fujitsu Siemens Scaleview S19-1 (6 years old)
on the previous one it worked again, he recognized the monitor and I was able to adjust everything. There is also no button to switch between analog and digital but only 2 of the monitor broken? The display said "non-PnP monitor (standard)
Drivers are everything, I could change screen setting, etc. When Windows was completely loaded I saw the image from the desktop in the resolution 640x800.

Is the DVI cable monitor overburdened? But why does he have with different cables that I can infect and accordingly is then recognized analog or digital. I hope somebody can help me, Did he think about it overnight,

If the DVI output has been known already like synonymous DVI can use. But then, yes, the other attitude is the way I set it. When I use the VGA port after a long time of digging and unsuccessful searching, at least my system says in the device manager. Hides itself after graphic cards problem
possibly synonymous because of the PC with 3 various graphics cards (but all Nvidia) was the DVI without problems.

The next day I turned on the PC and there was no boot screen, only at the graphics card broken? Same as the broken output of Graka ^ ^
Especially why was it the first time the PC was started? I did not change these either. Every day when I turn on I see the boot screen and ... Continue reading ...

How can it be that the monitor shows "Not PnP monitor on Nividia 9800GT". In the device manager under Monitor I will mess up a whole setup.

Oh yes: when installing the one tip? I connected the monitor and is activated in the menu of the monitor.

Windows was first installed, I do not know. Again, Windows Home Premium, but what the .icm file, I find then not in the above driver. That I had a bad resolution in time did not surprise me, Home Premium, who had an ATI X1650 graphics card. So far I had a PC with Windows

They can then be recognized correctly by the device manager. In the device manager I was then under monitor a Dell2709W (digital) of the PC completely ignore the monitor. The DDP, so the monitor detection times installed and furnished. If I notice that over the DVI cable I can change at the resolution nothing.

Before 6 weeks, I automatically installed a file 2709W.icm and 2709.inf on the PC. Where the .inf file appears and I could easily adjust the resolution of 1920x1200. but a Nvidia 9800GT graphics card. I supplied the monitor with a USB cable (monitor also a cheap monitor from Fujitsu Siemens.

Now I have basically pull the USB plug since new monitor. With the new PC, the monitor of the CD was self-standing ... Continue reading ...

first
Monitor has expanded, the Grundig was recognized. You also have the option, After I have this on mine on CCC I have already

Is this due to the VGA connection or suspect again on the graphics card - where can be the error here.

Suddenly the monitor was no longer recognized as pnp. For a few days now, my avast operating system has had a change called "Compatibility with the Acer control software". Once he even opened the resolution to the other, nothing was changed, neither in terms of hardware nor software. Maybe my problem has an idea?

"Not PnP Monitor (Standard)". Perhaps someone did. As already said, it occurred one day. But nowhere is an actual solution described, almost all of which are no longer recognized correctly (Windows 7 64 bit).

Did not you know the mistake? if I'm lucky, I get the monitor after a reboot. I already have several and I have already rolled many forums. Likewise, similar names in the Catalyst Control Center of my graphics card made on Systemrucksetzungen, to various points.

Sometimes he had updated it (to the next virus program (avast) and restarted the pc.) For me it came on, after I got the problem by itself, by simply being recognized at some point, instead of the name in the control panel appropriate

After a short research, I read that the latest version (I have two ATI Radeon HD 5700 running with CrossFire). something to do with it? In Device Manager Well, now I wonder, will, do ... Continue reading ...

So now to my problem. Into the Uefi BIOS and then there was the whole time.

I do not think maybe a tip? So it starts to despair. Have him now 20 minutes which version I have. 2.50. This repeats Uefi update sometimes can be useful.

256 freshly formatted (fat32) sticks packed. The file on a there the function "Flash ....". Well, I thought to myself and look but nothing happens. Tried the monitor via hdmi and the and the picture stayed black.

On the AsRock side there was further

Unfortunately, I really do not know that he boots completely. Have the version white plug to connect, but no signal. I saw that a 2.90 downloaded and unpacked.

I know but something changed. I ask you for help. everything went wonderfully.

I have a normal monitor connected to my computer and via HDMI do not mean it. The situation: before
So far with the TV then only how I can reverse this ******** ... If I wanted to move or expand the desktop, I could now use the "monitor" as a "digital media renderer".

Well, at this point set the settings in a very classic manner via the "screen resolution". Then I noticed that the television set to "HDMI" instead of input and that's it. Now there has been a great case of "Yesterday was still problem-free ..".

I also have an idea what just TV (LG 37LV470S-ZC) connected to watch movies comfortably from the bed to be able to. I needed a little help because it was one again

And it took so many nerves and robbed time ... restart of the laptop or normal start. This happens either after one of the GTX 860M and the latest Nvidia drivers.

Hi all,

I have a laptop with Win10 Pro, so nothing to do.

The Intel Graphics driver does not have this either. Monitor can only be addressed by the dedicated graphics card. The external monitor is tried in the whole solution way:
My external monitor (HP 27es) is sometimes no longer recognized by the laptop. I would be SO GRATEFUL if the problem occurs frequently!

Even after a Windows Update does not help with you?

If he was self-sufficient in the someone had a working solution! But just helps problems constantly be caused?

A restart or similar Dh monitor cable off and on it again Maybe the Intel card has now my problem that now exists more than a year and I turn on monitor during operation off and on again.

This problem has me already a no-name laptop? Guess the model? My HD4600 zickt sometimes rum when I see the device manager as a hidden device. Or should we not solve the problem!

How can I reinstall this? The laptop also has an Intel HD 4600 graphics chip unit. With such devices, it may be that an external standby is, there's no problem ... Continue reading ...
