wrong, VGA as spec has a max resolution of 640x480. the VGA connector supports many VGA standards, the highest of which is double that of 1080P.
further investigation shows the xbox 360 will only allow you to choose from a list of screen resolutions that your monitor tells the XBOX it is ok to use. this happens on the data line of the VGA cable. not every video card or monitor supports this two way communication but the xbox 360 does. so does every computer monitor made in the last 10 years. my 46" sony supports the standard so its safe to say that HDTV’s also do this. my 19" monitor is running 1440x900 with the 360 since its my native resolution for the monitor. I would rather scale it all in the xbox than scale it twice.
this relates more closely with old NTSC standards than VGA. older 1080P displays will support 1080P over HDMI only while the standard at the time was 1080i for component cables.
thats a pretty fair statement but I find that it often falls on the video card and the operating system to display non-standard VGA resolutions. why would a 1080P TV not display 1080P? that makes no sense at all.
thats what it says on the package of the official xbox 360 VGA cable that I purchased 3 years ago. old information. don’t trust it.
depends on your computer monitor. the crappy LCD’s are actually VGA native. your digital inputs get scaled and converted to the native max resolution of the analog LCD. I own one of these too so I know. if you have no VGA connection on your LCD and it did not come with a VGA adapter, then you can bet it is DVI/HDMI native. VGA is still king when connecting arcade boards to anything.
sorry to spam you. just wanted to post up some good information.
