ive been working on a problem for someone who hooked up a new HP 24inch lcd to a desktop pc. He has limited eye site so has the screen zoom set at 200%. The resolution for monitor is set at 1280/720. On certain webpages the horizontal scroll bar will not stay over to far left or start of page but will spring back to the middle of the page on its own. If you try to hold the scroll bar over to the left it starts skipping across the page and wont stay, therefore only allowing you to view the center of the page. I have the latest drivers installed for monitor. Obviously its not a monitor issue but a pc /display issue as when the monitor is hooked to a widescreen laptop it works fine. I have played with all resolutions settings and different zooms. A couple months ago i realized the proper driver was not installed for monitor, i installed it and everything worked fine for a month, now the scroll bar is back to its old tricks. Any ideas?
