I have a vista 32-bit laptop running vista business. I have just purchased a new NEC 24" LED screen to work as an external monitor for it. When i first installed it was picked up the correct max resolutions for the screen without a problem, however there was a flicker on the screen. So i then plugged the screen into another laptop (XP) to check whether the flicker was due to the screen or the laptop - no flicker.
Then since I have re-plugged it into my vista laptop, the max resolution it shows in the display settings is that for the laptop, not the screen.... How do I correct this? Also what do I do about the flicker, as it is a LCD i cannot change the sreen refresh rate, it s set at 60 hertz.

You're trying to use this screen as a new monitor for the laptop, rather than something like extending the laptop screen, correct? If so, make sure that in the Display Properties for the screen, the "This is my main monitor" checkbox is selected. Hopefully this will enable the video hardware to recognize the full resolution capabilities of the monitor.
Oh boy, that really is a headache. The most confusing part is that the monitor worked at that resolution before, and now is unselectable. I'm afraid I don't have any more answers, those are the only things I could think of. Hopefully someone more experienced in this area sees this question and is able to help, but I really don't know what's wrong.
Apologies & best of luck.
you need to close the lid of the laptop for the video card to use the native resolution of the monitor, if you have both monitor and laptop lid open, it will stay at the limit for the laptop LCD.
make sure under power profiles, advanced settings, that you set WHEN LID CLOSED, choose DO NOTHING from the drop down list, as with most laptops, this engages hibernation mode.
thank you. I have found the solution myself - i have deleted the HKEY_CURRENT_USER/software
Any help on this one would be fantastic...
thanks
sounds like you may have to re-install the Intel driver software manually. remove any listing in add/remove programs, and re-apply. you should get the latest driver from the laptop maker, not from Intel's own site if you can avoid it.
getting the chipset driver won't hurt either, as it will allow the system to recognise all the Intel components, such as audio, video, drive controller etc.
Quick question on the above answer - I have downloaded but not yet installed a chipset update from the manufacturers website - however the graphics update on their website is older than the graphics update that i previously got from Intel and have previously installed - should I go back or leave this as it is?
thanks done that, but still hasn't corrected the igfxrvc module - so not sure what to do next - i know there is a igfxrvc.exe file in the system, but cannot find anywhere to download a new one in case this is corrupted...
I can however now get up the monitor adjustment section of Naviset (software that comes with NEC screens, although it wont see the monitor (everything else does) just says "No DDC/CI monitors found". very stange when my graphics card does support DDC/CI as confirmed by the intel website and everything else is working!
if you unpack the Intel drivers file (Winzip or whatever you use), you should be able to extract all the files and one of them is bound to be the one you need.
search your drive for this file to get an idea of the date stamp and size of it, perhaps even renaming it and re-installing the software. These will likely be in the SYSTEM32 folder.

It may not be possible, depending on the restrictions of the video card for your laptop. However, check the manufacturer's site for updated drivers, and see if that adds any new resolution settings.
