Got a big puzzle with my screen resolution.
First go a nice amp witch is a Yamaha RXA-1000. Second i run a HDMI cable from my computer to my Yamaha all of this is fine. Now to the resolution. Usually i should select duplicate these displays and voila i should get my image on my desktop and also on my big screen thru my Yamaha since everything is hooked up via HDMI. But no for some reason i get a different image on my big screen then on my desktop. Very puzzled about this. Also if i close my Yamaha then of course my big screen closes but why does my desktop screen also closes this also is a puzzle for me. I have also tried the duplicate these screens and get the same results except i get the right screen on my big TV. I know it should work because this is my friends computer and also Yamaha and i have the exact same thing with the Yamaha and i have no problems everything works just great. The only difference between him and me is that my desktop has a 24" Asus monitor witch is about 1 year old and his desktop monitor is a 21" HP but quiet old and i would say about 15 years but a darn good one. Can it be that this old monitor is causing all the trouble as it is not compatible with all the new stuff like this video card ASUS (HD7790-DC2OC-1GD5) Radeon HD 7790 1GB GDDR5 | 800 MHz Clock, 5000 MHz
Any help would be well appreciated
