I want to use the NS-55L780A12 with an Atlona PROHD82M scaler/switcher/matrix. The connection is via HDMI. The Atlona unit upscales all input formats to HDMI 1920 x 1200 (16:10 format). I want to make sure that this signal will be processed OK on the 55L780A12. I believe I can adjust the monitor to fill the screen fully, or just leave narrow bars on the sides. My main question is whether the 55L780A12 will sync this 1920 x 1200 signal properly via the HDMI input.
