I use a Dell Inspiron mini10v netbook with LXDE (fully updated).
I have just bought a Samsung T27A300 small-TV/large-monitor. The problem is that the Samsung only has HDMI inputs (+RCA type audio-video or composite) while the external monitor output on the Dell is 15 pin VGA. (It came with a HDMI to DVIa cable, but that isn't much use.)
I've bought a VGA to HDMI converter box and that works, but there is a catch 22 situation. I cannot set the resolution of the external monitor using the PCC "in absentia" - it has to be plugged in. The converter box determines its resolution from what it is plugged in to, and picks up the 1024x600 from the Dell. Then the PCC says "this is a 1024x600 monitor" and won't let me go higher.
I tried in windows XP and was able to set the second screen at 1080p settings - but what would I want to run XP for when I've got LXDE
The main reason I want to hook up the Samsung is that we have a number of Zone 2 DVDs from the UK and would like to watch them on the larger screen. (Can't do that from XP without purchasing(!!!) some extra add ons for the WM player - and why do that when it runs well with free Linux software.)
So how can I set the external monitor signal to 1080p dimensions before
I plug it in? The 1024x600 isn't bad, but it would be nice to get the maximum sharpness.
