That’s a 1360×768 panel (w-xga) and supports 1024×768 in PC mode, so in theory the “256 V.Active tweak” could work (60Hz only). Check this thread. If you’re using PAL consoles, then instead reduce V.Active to 240 and hope for 50Hz 720p.
If you manage PC mode to work, you should probably use the “unscaled” picture format for best quality.
Mine is full HD with w-uxga panel so they are not so similar after all.
