Has mirado lo que te he dicho.
Mira en el manual de la placa base, que debe venir la tabla de resoluciones soportadas por la GPU, ya que es integrada en placa la tuya.
Acabo de mirar en mi placa del otro PC que lleva el mismo chipset y no soporta 1366x768.
Soporta 1360x768.
No sé de dónde c**o se han sacado esa res... Por eso seguramente no te va.
Prueba a 1360x768 a ver que hace.
De todos modos creo que mirando las opciones avanzadas del panel de control de NVIDIA, podrías seleccionar una resolución a mano, estableciendola en modo manual. Prueba, repito.
LUEGO TE LEES ESTE TOCHACO, entenderás bastantes cosas.... que cabrones son los fabricantes macho...:

Y ESTO OTRO:
Standard EDID codes dont exist for 1366 x 768 resolution ...
causing lots of angst when people buy a 1366x768 panel and try to hook it up with VGA connector to a PC or a game machine, to find that 1280x768 is really the only clean resolution they get, and pushed to 1366, everything is rather blocky/blurry... doesnt look right. I'll bet you didnt know that, or if you just bought a 1366x768 HDTV you just found this out and you are seriously pissed about it. For DVI connections its a bit different and you really need the display card MFG and the monitor to behave properly, but not a lot of systems have DVI, you need to get that as an upgrade to your PC. The best solution i have for you is to replace your Graphics card with an
nVdia 7600 GT or 7800 series graphics card. At this moment, nVidia does it best. For the technically adventure-centric DIY guy, a shareware program called PowerStrip 3 will attempt to control your graphics card, download it here:

You will need perhaps a DVI to HDMI connector cable. Get that here:
