Lots of aliasing in footage

I don't have my computer setup yet so I'm watching the gh2 footage via hdmi to dvi cable in to a computer monitor. I'm seeing a lot of aliasing on diagonal lines. Is this normal? will it be antialiased when I use an editor later? I'm recording in 24H.
 
in my experience, thats just whats going to happen when you try to use a bare computer monitor in place of a proper reference monitor.
 
I haven't even been able to get my gh2 to work through a HDMI-DVI cable. Probably just that monitor though.

However, when working with monitors that need to scale footage from a source, they tend to do a poor job of it and it leads to aliasing, blocking and other artifacts.
 
a monitor and TV are somewhat different in how they render stuff. Monitors aren't very good at scaling their signals, especially when doing fractional scaling such as the OP's 1200->1080. They usually depend on the video card to handle the scaling and stuff(which do it much better than the monitor could). The monitor is usually designed to display full screen at it's native resolution so it has a tough time scaling stuff that isn't exactly the ratio that it is natively.

1920x1200 is 16:10, not 16:9 so you'll get pixel resizing and stuff that make it look strange. I had this happen on a few monitors until I just bought one that could scale well.

A lot of new monitors can handle this and some of the older monitors can display letterboxes but most can't deal with the odd resolution.
 
No problem.

I had an older 24" monitor with DVI and I ran an HDMI->DVI cable to it to watch stuff from the GH1. It had the same problems as the OP had, things looked strange and blocky with aliasing. I then got a newer 24" monitor with HDMI input and input the GH1 and it looked clean and nice.

What's strange is that my GH2 through the HDMI->DVI cable won't display on the same monitor that the GH1 can through the HDMI->DVI cable(with blocky look). I haven't figured that one out yet.
 
Is there a way to display content without resizing? i.e. having a content window at exactly 1920 x 1080 pixels that is smaller than the lcd screen.

If there is way it's usually in the menus to enable/disable "fullscreen" or 1:1.

It looks like I need a new monitor with my new computer. What types of features should I be looking for in a new monitor?
 
i got a dell too, the u2410, its a complete other technology than the 2405, but check if u dont have 1:1 in 'Display Settings' / 'Wide Mode'
