"Screen format full" message

[#1]

I am running Windows 8, not many problems, but a persistent one is when opening up after the screen has gone to sleep I get the above message, and the top of the screen is blanked. After a few moments the message goes and the screen corrects itself. I have made certain that I have the latest video driver for my NVIDIA GEForce GT 620M display adapter. Any Ideas please?

Some conflict between your display setting and the ones that your monitor would like to see?  So you monitor wakes up with its default setting which does not match what you are using and takes a few minutes to adjust itself?  I'm just guessing.

Thanks, that could be so, if it is how do I establish it, more importantly how can I correct it!

[#4]

What are you using as a monitor?  Could this be text displayed by the monitor rather than the computer?  It sounds like the monitor is telling you that it is set to 'full' aspect ratio...
You may be able to check if this is the case by unplugging the video feed to the monitor and seeing if you get the message when you plug it back int?

It a Sony all in PC, so it is not possible to unplug the monitor independent of the PC.

[#6]

And what display resolution have you set?

[#7]

1920 x 1820, the recommended.

[#8]

Is that a typo -  1920 x 1080 is more usual

[#9]

That (1920 x 1820 is what is says!

So your screen is almost perfectly square; more so than the older 4:3 aspect ratio used before wide-screen came along?

And squarer even than the 5:4 screens (which is obviously squarer than 4:3) 

[#12]

what is the model of Sony you have

[#13]

JohnCT never came back; I wonder what happened.

Just a thought........ this may have nothing to do with "conflicts" or software... but is just and "advisory" message  as in.....

Screen Format .............. FULL  i.e defining that the "screen format "  is FULL SCREEN  ? ? ? ?

I apologise for the delay in answering, I was indisposed then my broadband was down for a week. Thanks you one and all for your replies, If you are correct RR it is a nuisance as the screen takes several seconds to get back to its correct display. The system is Sony L series 15/8/1/2/t Aio, it was purchased from John Lewis, they have offered to take it into their help desk and check it out, but that would mean doing without it for several days, especially as the nearest JL is 30 miles away. Me thinks I will just have to suck it up!
