Great. Then you'll be marking this thread as SOLVED!

I'm assuming that power actually goes off and this is not an error code blinking on the power LED. On that assumption, logically it should be one of three potential causes:

1. The power section...

Please start your own thread and provide full details of what is happening.

I realise that English is not your first language but what you have asked unfortunately doesn't make sense.

Please mark this thread as SOLVED. By the way, what make/model is your UPS? It's a matter of interest to know which UPS brands have imperfect sinusoidal output.

No it won't damage anything if my diagnosis is correct - i.e. on battery driven UPS only. It means that the sinusoidal interference or drift is causing an electrical resonance that comes out in a...

The buzzing normally changes if you change brightness/contrast. It should reduce buzz if brightness is turned up.

I'll make an informed guess here.

I think it's coincidence - you're running...

Hi Mahela

As you know I've been dealing with your situation on the other thread.

Rik's got it right, of course. I have two viewsonic monitors connected to my HD laptop. Neither monitor...

Well, I tried it this morning.

I put both cables into a Viewsonic 2265 - that's VGA & HDMI. This is what happened:

1/
On boot, the signal definitely came through VGA because I could see the...

You can either wait for me to try it some time this week (when I eventually re-boot)- no harm will result but I can report behaviour and which cable becomes the active one after booting.

Or you...

You're welcome. Do please mark this thread as SOLVED.

Yes - the monitor is adjusting refresh rate from VGA to whatever setting the now available Registry tells the driver.

Nothing wrong; nothing to repair. My main monitor (LCD) does this.

Try it. I can see what you want to achieve.

I could try it but (sorry) can't be bothered. No harm will result. My guess is that the VGA port will be acquired first and will be retained.

Let...

There is a straightforward reason. When you boot, default VGA video drivers based on the BIOS of your graphics card are used. That is because there is nothing else from Windows loaded at boot up. ...

The browser will minimise to the last place you moved it to. So a dead pixel in a particular position will appear in the same place.

I think we're going round in circles. You have a dead pixel -...

So what happens when you move the non-maximised browser window?

Ah - that's a whole different picture (forgive the pun!).

What follows is logical deduction rather than a definite answer. If the dead spot is definitely in a different position then it could be...

A moving "dead pixel" must be due to the video circuitry and not the CRT. You might care to tell us which video card you have. It contains a frame buffer and if this is not populated correctly,...

It's tempting to ignore your question because the answer is something you don't want to hear. But it's quite clear:

Either get the screen replacement and all interfaces right

or

Forget it...

jbennet is so right! My Quaddie has a 7600 and we only took the upgrade drivers from Nvidia.

But sometimes (I've not seen it with Nvidia), Windows updates device drivers like the one for my...

The on-board graphics will be automatically disabled when you install the 9800.

So does it all work now?

You're doing some hairy stuff.

To the best of my knowledge, the identification echanism on a laptop is in the motherboard interface circuitry - but I'm not sure.

You need a cable that matches...

Laptops don't have bulbs. They have (say) 1280 x 1024 leds x 3 for the prime colours. So if the whol screen is dark, either the leds power is weak or the video settings are wrong.

Or have I...

So it's the video driver settings. I have a laptop with an nVidia card; for movies I have to go into the nVidia control panel and reset Video settings to default. It then brightens up properly but...

Please mark this thread as SOLVED.

But I don't think that your problems are at an end. Just going into the BIOS and changing nothing changes nothing.

Anyway, let's hope we don't see you...

What throws me, and I'm sure you, is that you did a reboot in the past to clear the problem. That fact could invalidate the suggestions made to you other than some malfunction or other.

have you...

I can only think of two possibilities apart from hardware or driver malfunction:

Monitor properties are set at the wrong refresh or sync rates. On a laptop that shouldn't happen, but if you get...

Do you see a full screen of information or is some cut off? And does it look 1024x768 what you can se8?

If the latter, then, diagnosing at this distance, I'd suggest a hardware problem.
