I have a home-built PC with a Radeon R7-260X graphics card. This card supports DVI and/or HDMI. My monitor is a Dell ST2421L and it also supports DVI and/or HDMI. I am a hardware sort of guy but graphics are something I admittedly don't know a lot about. My main uses for my machine are browsing the internet, watching movies, and playing World of Warcraft. My question for the rest of the group here is, which would I be better off using, or better yet, which of the DVI and/or HDMI would I be be better off using? Thanks for the advice, I look forward to the replies. kb5zue
