DVI to HDMI Vizio 4K No Signal

[psigna]

I have my older DELL desktop connected by DVI to and HDMI converter, then connected by HDMI to my Vizio 50 inch 4K LED D50u-D1. It works fine, signal received and everything, until I turn the TV off. Then when I power back on the TV I get the No Signal error on the TV Screen, and I have to force reboot the computer because I cannot access the normal shut down routine because there is no signal to see the screen. I previously had this computer hooked up the same way to an older Sony 50 Inch HDTV, but did not have this problem.

Once I reboot the computer the signal is received again. I don't want to leave my TV on all of the time. Any suggestions?

I had the exact same issue with my older monitors when connected to a DisplayPort to HDMI active adapter. I'm sure this will apply to you too. I had to build a custom HDMI Coupler that tricks the computer into thinking there's always something connected to the HDMI port (in your case, the DVI port, but since it goes out as HDMI, it will have the same effect)

I didn't find the original post where I read about it but this forum has the same explanation if you scroll down a few posts:

It's an easy "hack" as long as you have a soldering iron. And if not, I'm sure anyone at any electronics store will be able to build it if you tell them what the forum says. It can be done in less than 5 minutes and the parts cost less than $6.
