Im trying to hook Roku Express to my just my old HP s2031 monitor via HDMI/DVI. It will show the Roku screen for about 15 seconds then no signal and goes to sleep. I've hooked the monitor up to my laptop and it works fine and the Roku works with the TV. I've factory reset and both are on auto detect. What can I do? Thank you so much.
That monitor is 1600 x 900 which isn't a resolution found in TVs. Maybe the Roku can't output that. You can try connecting the Roku to a TV and set the resolution at that or below and see what happens.
