Dreamcast VGA to DVI

I am building a retro game room and would like to connect a Dreamcast to the DVI input of a Sony Bravia CRT TV I have. Not looking to upscale, just want a clean 480P signal. According to the manual the DVI input cannot be used for PC input and accepts only HDCP EIA-861 standard. Am thinking I cannot just go with a VGA to DVI adapter. Can connect most consoles to it with a HDMI to DVI adaptor, but believe the Dreamcast outputs different via VGA than most consoles. Before I spend money on the vga cables and a VGA to HDMI converter box (which I could then use the HDMI to DVI adaptor), would the TV even be able to accept this signal?

Appreciate any advice!
