Maximum resolution video out?

[Dutch]

Hi,

I know it takes the 950 chipset, up to 224 shared ram.

Anyone tried 1920x1200 resolution with video out or has max resolution specs? TESTED?

Thanks.

Nope but,.....

I do have my external 24" screen running at 1680 x 1050, and the One screen at 1024 x 600. Both at the same time, in dual screen mode - not mirrored.

Thats quite cool it does not mirroe the screen!

Can you test getting it at 1900x1200 or was your setting the max setting?

Thnx.

Hi,

I have used 1920x1200 with my 24" monitor. Only mirroring works nicely. Dual screen mode is very laggy, it takes something like 10 seconds to move quite small window across the whole desktop. I use the following xorg.conf which allows me to start X without crt connection and enable it later.

I think there might be some sections that aren't necessarily needed but I decided to paste the whole configuration for reference. The command which enables external display is " xrandr --output VGA --mode 1920x1200"

I'm using debian sid as my distribution.

I hope this helps someone...

Hi everyone,

I was reading four threads regarding external VGA output. I have referred this issue with people at Linpus, it seems that Acer has classified this issue as non-critical, which is why it's not resolved until now. And, they would probably consider it as an immediate concern if more people would complaint about it.

I have a 1920x1200 screen running in extended desktop mode in windows xp. I haven't had a chance to create a good xorg.conf file in order to get it working in Linux. Once I do I'll post it.
