Screen Issue

[Old_Geezer]

I am seeing large black characters all over monitor screen 2. I do not know why or how to fix it. They appear over the wallpaper or over any application window opened.

It first happened last weekend, and I fiddled with the Control Panel Screen Resolution and the Device Manager and NVIDIA control panel and NVIDIA GeForce experience. I also swopped over the two monitors, and both VGA / adaptors at different times and the fault seemed to follow the monitor (or it's driver I suppose.

I thought I'd eventually found that the PC was confusing the Philips with the Hitachi in NVIDIA contorl panel, and corrected it, and the issue went away then. But it has happened again today and I can find no such mislabel and so wonder if I mistook something, and the "fix" was purely coincidental.

Every check I make claims that the present driver is the latest and best.

The PC claims the monitor is a Philips CM0700 (21B). The video board a NVIDIA GeForce GTX 470. Windows 7 Ultimate, if that is relevant.

I've tried disabling the monitor in Device Manager and then re-enabling it. I tried deleting it and then searching for it again. Neither fixed it.

This month I could do with having to scrap a monitor and buy another, like a hole in the head. Financially April is not a good month. Although there is nothing stopping me going back to a one monitor system

Any thoughts ? I'd have suspected memory issues but given it seems to move with the monitor and that presumably doesn't have memory...

Check the back of the monitor to get the Model No/Serial no. and go here and download and install the latest drivers.

Let us know what happens

Away for the weekend now, but thanks, I'll try Monday.
All very strange though. Been ok in the past.

Weird. Whilst I have been away the main monitor has been swopped to the other, the resolution on both has changed, and now both are shown as generic non-PNP monitors !!!!!

Something very strange going on.

Nice try but it didn't get far.

Can not see something marked serial number but I take it that must be the string of digits that isn't identified. Tried putting in the Model Number (21B07M) and the Product Id and what i took to be the Serial Number, and "CM0700" into the search box. Philips claims no knowledge of any.

I wonder if they make a conscious decision to ignore their CRT monitors. Even searching for "monitor" didn't help. Came up with loads of stuff, lots unrelated to screens, but where it did come up with a PC monitor it was numerous newer models.

Maybe I'll Google for some dodgy driver websites tonight and see if that comes up with anything.
