So I've been using this computer for months to game and I moved houses and i dropped the box where it was and now the gpu shows input not supported when I plug the HDMI into the monitor and I tried it on another monitor and same thing happened but then I tried it on my smart TV and it works during boot but then my TV changes to a higher resolution and it stops displaying and I went to start pc in safe mode and then it works but only on the smart TV even though resolutions are now low and it shows the same error on the monitors "input not supported" I have a r7 260x cpu is i5 3470
