1280x720p is too big in my TV LG LCD 32LC2R. WHY?!

[matrix_qw]

Hello community.

I am using ForceWare 178.24 with my xfx 7900gs 256ram in CLONE mode
My TV supports 1280x720p and 1920x1080i

For desktop fit on the TV i have to create a custom mode with the resize option, ending with 1152x676.
Some games i tried don't allow to use custom modes and if i use 720p i can't see part of game information.
Same happens with 1920x1080i, gets too big, but i remember once using (i don't know wich driver version) 1920x1080i and it DID fit !!

So, is this a problem with my TV or with the drivers using incorrect parameters ?

Even if i could find the driver version that allowed me to use 1920x1080i correctly, in interlaced mode screen gets too much flickering its annoying, so 1280x720p is what i really need.

Any clues?
I am really desperate !!

Thanks in advance for anyone who can help me.

I had that problem too, and the problem was the hertz refresh rate on the monitor. It's likely the hardware, not anything in the software. My monitor is 1080p at 60 Hz, and the 1920x1280 was too much for it to handle, but the 1920x1200 works just fine.
