I have a Toshiba 19LV506 combo unit. I've been using it with a VGA connection to Windows 7 computer but I now have a Windows 11 computer that uses only HDMI. The displayed computer screen is now slightly larger than the physical monitor screen. Small parts of the top, bottom and sides are cut off. There is a Picture Control Adjustment function in the menu displayed on the monitor screen, using the remote control, to adjust the picture. But that appears to be available only in PC (VGA) mode. When the monitor is set to HDMI mode the Picture Control Adjustment option does not come up as a menu selectable item on the screen. How can I adjust the display so nothing is truncated?
