Your Toshiba Regza display has two different inputs available for connecting to your computer. The first option is through a standard VGA cable. This connection provides screen resolutions up to 1280 x 1024. The second option is through an HDMI cable. Using the HDMI cable provides resolutions up to 1920 x 1080, or 1080p. Unlike many similar displays, the Toshiba Regza can actually accept a large variety of refresh rate inputs. However, every input refresh rate is converted to 60Hz within the display. As a result, Toshiba recommends you set Windows to output at 60Hz to avoid this conversion process. Doing so ensures maximum image quality and smoothness while minimising the risk of damage to the display device. Set the refresh rate from within the Windows display properties.
Click the "Start" button. Type "Display Refresh" in the "Search programs and files" box, and press "Enter." This opens a "Change the appearance..." window.
Click the "Advanced settings" link. This opens a properties dialogue.
Click the "Monitor," then locate the "Monitor Settings" section.
Click the "Screen refresh rate" drop-down menu, then click to select "60 Hertz." While you can also select any other listed refresh rate, keep in mind a higher or lower refresh rate is going to convert back to 60Hz on the display.
Click the "Apply" button. The screen on the Toshiba Regza will briefly turn black, and return with the recommended refresh rate.
