Hold down on the spacebar, click down in the viewer and drag it up. Or try clicking in the lower left corner of the viewer where it says "100%" and selecting "Fit" or "Fit up to 100%"
Dunno if it's getting confused by the extremely wide aspect ratio of your monitor or what (or is it a dual monitor setup spanning both?)
Thankyou for that reply - I shall try it out and see what happens.
NOTE* It's a single Acer Predator 34" widescreen monitor.
Nah - it's still all screwy. If I do hold the space bar and drag it up the top line of the black work space seems to be masking the area. For instance - if I use the pentool to create a red diagonal line (trying to create a lower thirds for a video) and click on that black area the actual line itself appears below that work space. I'm not sure if it is the monitor but I read everywhere how a widescreen monitor is supposed to be great for that kind of work. If the monitor is the issue though then I'll have to cancel my subscription and look elsewhere I guess which is sad.
this is probably a display issue but could that could be resolved. what is your current resolution in your display settings?
try updating your display driver. what is your GPU name? try re-installing after effects and tweak your driver settings if you have it. for example here's a similar thread that tweaked his NVIDIA settings after re-installing and solved his problem: CreativeCOW
Acer Predator x34 ws monitor - current resolution is 3440 x 1440.
Nvidia drivers were updated yesterday. My gpu is a GTX Titan X (12gb ram)
