Im so pissed. Just re installing windows 8. Hope that help, but i dont have a 7490HD. I got an HD 6490 M.
thanx Solarstarshines you did your best dude
all you had to do was yank the lead to telly out.
Restart pc - so it only finds monitor.
Turn off puta/ plug in but do not switch on telly.
When puta is running on Monitor
Switch on TV/put it on correct HDMi setting with remote
Graphic card should 'rediscover' hdmi/TV and set up correct screen res
Help available from there if it doesn't discover correctly.
(You may have incorrect HDMI lead which should be 1.3C or 1.4)
