1:1 pixel mapping in hardware + software

[OCdude]

Would I be right in thinking that monitors that can do 1:1 pixel mapping in hardware (Dell 3008WFP etc) tend to be 'laggier' because of this feature?

I'm curious as i'm wondering if this is how the Hazro 30" manages to have really quick response times (as it has no hardware pixel mapping).

Plus - is software pixel mapping any good, or total pants compared to it being done in hardware?

I'm not quite sure I get what you mean.

In an LCD monitor the thing that creates the lag is the scaler chip, basically the input signal has to be processed by the scaler chip before being output. The 'lag' is the processing time of the scaler chip.

The scaler lets the monitor accept signals that are not at the monitor's native resolution. So for example in a Dell 3008 which has a scaler, you can set your GPU to output a 1920 x 1200 signal. Then you can tell the monitor to work in 'fill' mode and the scaler will stretch the image horizontally and vertically so that the image becomes 2560 pixels wide x 1600 pixels high. Alternatively, you could have your monitor set to 1:1 mode in which case the scaler wouldn't have to do anything and would display the image at 1920 x 1200 with black borders around the edge.

The Hazro and the Dell 3007 have less lag because they have no scaler. That is why they can only accept and display 2560 x 1600 signals.

Hope this makes sense.

Yeah that's pretty much what i meant

Does the scaler cause lag even when it's not being used? Because the 3008 seems to have pathetic lag (60ms @ 2650x1600) compared to Hazro (~7.5ms @ 2560x1600).

Also, would the Hazro look noticeably worse than the Dell if I was to say, connect an Xbox and use 1920x1080 ?
