I have a RCA HD tv, the rledv2479A model. When I plug my PC in via HDMI the screen is very zoomed in, cutting off half of the windows logos and etc. On my system settings there is no "aspect ratio" or any way to adjust the fit whatsoever (beside a section that gives me the option for normal, zoom, wide and etc. except every single setting is still zoomed in) Also, on the remote there are no "aspect buttons". Help?
