Good afternoon everybody,<div><br></div><div>My problem in a few words : my TV LG 55LW4500 is 1080p capable but Xorg seems to use interlaced mode (1080i) .</div><div><br></div><div><br></div><div>More deeply, what I did to confirm the available resolutions : </div>

</div><div><br></div><div>Strange... the very last line dos not specify Interlaced but contains a 'i', meaning it. So, I skipped this one too.</div><div><br></div><div>We got this :</div><div><br></div><div><div>(II) NVIDIA(0): "nvidia-auto-select" : 1920 x 1080 @ 60.0 Hz (from: EDID)</div>

</div><div><br></div><div>=> My understanding is that this list is the available NOT interlaced resolutions.</div><div><br></div><div><br></div><div><br></div><div><br></div><div>I put them in my xorg.conf (section Screen => SubSection => Modes), adding all available resolutions (not only 1920x1080)</div>
