The screen is located far from my office so I can't be in front of it to test, that's why I haven't spotted it wasn't working. I tought it was because when i take a screenshot with 'scrot' i get a full screenshot in 1366x768 and everything is clean, but the TV itself shows a 1280x720 display. I should've watched the Xorg's log instead of simply assuming it was working with a screenshot, but anyway now my problem is the same : The PC is configured in 1366x768, but the TV don't care and shows a 1280x720. Anyone got a similar issue and a way to fix it ? Thanks, Francis Dubé
