Optimist - thanks, will check drivers also.

If it is a twin screen card then disabling the other screen will reduce the load on the card and if that solves the problem try and borrow a DVI converter to see if it makes any difference.

There is a little + sign to the LHS of Monitor(s). Click on this first and then select your specific Monitor.

ie, Imagine you had three of them, all differerent makes. This would allow you to select the Sony instead of the Yamaha and just do the driver for the Sony.

docproc , see it now for uninstall but very reluctant to do it , especially as trouble shooter says the device is working OK

It looks dangerous but that is the way to do it. Windows will always supply a default monitor if it can't install the right one, which is why you have something called 'monitor'. The default monitor is just a stab at it and may explain why it doesn't work properly.

However before uninstalling it I would look on the Dell site for a driver download so that you have the correct driver to give it if it can't find it on reboot.

...and it's good experience.

Kayak , intended going to Dell to have a look , device manager does show two monitors

docproc "good experience" , I,m having enough "experience" with the trading

noticed the drivers listed are ms drivers , is this correct?

also just looked at the cd's for the monitors and says on front drivers. Should I have used the cd to install the monitors , very confused

lol, they must have sent you the CDs for a reason :-))

They should work if you run them now. Afterwards you could see if the copy on the Dell site is newer.

kayak , maybe , but the "put together chart" said nothing about using the cd's , just connect to computer and fire up!!

kayak ,docproc , optimist - found the drivers and installed and device manager now saying they are there. many thanks
Unfortunately (Ahhhhhhhhhhhhhhhh) the problem remains although it seems to be correcting itself quicker. Maybe this ATI x800 graphics card is not that good for this purpose. and I know I read everything about Matrox but considered myself not good enough for self installation.

Any further thoughts?

Check in the same way that the graphics card is named in Device Manager, and download and install the latest drivers (http://www.ati.com). The graphics card you have is well specced and should certainly be able to handle things. Try setting colour resolution to 16-bit unless you do any precise work with photos etc.

I agree with Kayak re latest drivers.

How much proccessor power are yo using? Is the problem still there if you disable the other screen?

optimist, problem still there when one screen disabled.

where do I check for processor use?.

at present only running Moneyam and big charts in two windows on extended desktop

Maddoctor

You can check the CPU usage by right clicking an empty bit of the task bar and selecting task manager. However as you still have the problem with only one monitor CPU usage will not be the problem.

says cpu useage at 2% ? not overloaded then?

Well chaps have done the following re problem with screen breakup on scrolling:

1. Switched main 20" screen to DVI
2. Downloaded and installed latest ATI driver for graphics card.

changed to 16 bit colour from 32 , made no difference

Dell support replied saying
1. check resolution,done both screens at correct resolution
2. refresh rate , cannot change this from 60hz , no other drop down boxes.
3. Install new graphics driver

so no help there

is there a possibility there is a fault with the graphics card?
NOTE THIS PROBLEM IS ONLY WITH STOCKWATCH IT IS NOT ON ORDINARY PAGES, COULD IT HAVE ANYTHING TO DO WITH JAVA?

any more ideas?

Maddoctor, could you possible take a screen print of the problem and post it here? (I will send you an email address where you can send it if you cant host it anywhere) EDIT I cant send you an address because you dont have yours set ;-)

By the way 60Hz is normal for TFT screens, it would be low for a CDR but its fine for TFT.

Maddoctor

You have tried most things so a new graphics card is looming higher up the list. It could be a faulty card or an incompatibility with stockwatch.

One thing you may not have tried is to switch your primary monitor to the other one. Also have you tried swapping the ports that each monitor uses.

BTW have you got the problem toda6y when stockwatch is not changing?

I've just seen Spacemans suggestion. Try taking a screenshot when you have the problem and see if it shows in the screenshot.

I will have to find where in the system a screenshot is derived from but it may give an indication of where the problem is.

optimist, changed over monitor ports this morning as changed main screen to DVI , I did this because I read in computer active magazine that if you have a DVI port on a monitor you should use it. And let me say Dell told me to use both screens as analogue which has p*ssed me off. You wonder what you are talking to.

I have checked again today with stockwatch still the same to worse , the worse bit because it is not refreshing

Now the "I wish I knew more bit" how do I take a screen shot and post?.

I can describe the problem , when I bring up stockwatch(during market hours) the data for the first 30 shares are fine , when I then scoll down gaps appear and the little boxes to the left appear misplaced or have bits missing from them. Leaving for a few seconds (when I assume a refresh comes in ) that part of the page I can see reverts to OK. Pressing refresh also clears problem.

also I put stockwatch onto the 15" tft and whilst the problem seems not as bad , it is still there

My neophyte brain says refresh problem but where is it coming from?
Thank you for your suggestions.
