ATI 5450 Dual Display Problems

I just setup a new system with an ATI HD5450. I have the latest drivers installed from ATI's website. The OS is Win 7 x64. I have 2 displays, and Asus 19" LCD (main - DVI) and a Polaroid HDTV 19" (2nd - HDMI). With my last system I was able to run both displays at 1440x900 without any problems and everything would fit perfectly with no sizing issues. Now with the freshly built system they are both set to 1440x900 (according to both windows and catalyst) but on the HDTV when I maximize a window it goes larger than the screen. Is there something that I am missing or is it possible the ATI drivers are not good and I should try an earlier driver?

Thank You

  1. Anyone have any ideas perhaps?
  2. Well, your HDTV is definitely only 1280 x 720 resolution. Your old system must have been converting it automatically or something but setting the resolution to 1280 x 720 will fix it I promise.

    Actually my HDTV is 1080...but no that doesnt fix it. Already tried every resolution and it is the same for all.
  4. Ok, I plugged in a d-sub15 cable and it works at 1440x900... Maybe there is something wrong with the HDMI output on the card

    My JVC LCOS TV was 1080 but would not display 1080 from the computer input. Just got a blank screen. Second output worked fine on another computer monitor. TV manual stated that through that input TV only supported 800 lines. Video card was not the problem, TV was. Reset that second output to a lower resolution and try again.

    Check your TV owners manual, you may have run into the same issue that I had.

    Hope this helps.
