i recently purchase a CenterStage CS-2 line scaler with the express purpose of sending 1365x768 native resolution to the NEC. My connection is via VGA to VGA. The resolution shown being received by the NEC from the Information page is 1024x768.


Question:


Do I have a CS-2 output resolution problem (Does the CS-2 only output 1365x768 via the DVI output) ?


Do I have a VGA to VGA cable problem ?


Do I have a NEc plasma problem ?


The pq is great so this is a matter of matching the CS-2 to the information of resolution being received on the NEC.

Perhaps there is no problem, just operator error on my part....



Also in researching the difference between the CS-2 and the NEC I ran across this in the NEC manual.


Supported Resolution:


- When the screen mode is NORMAL, each signal is converted to a 1024x768 lines signal

- When the screen mode is TRUE, the picture is displayed in the original resolution

- When the screen mode is FULL, each signal is converted to a 1364x768 lines signal


I have never seen a TRUE mode on the NEC. I will have to try the difference between the NORMAL and FULL modes to see if the CS-2 and NEC match resolutions. I am currently showing 1024x768 on the NEC which is mentioned in the NORMAL screen mode.

Question to NEC Tech Suport:

I am trying to achieve 1365x768 input resolution from an external Focus

Enhancement CenterStage CS-2 line scaler. Right now the line scaler is

set to scale to 1366x768 but the NEC plasma states the resolution is

1024x768 under the Information display.



Response from NEC Tech Support:


The plasma may be "thinking" that the signal input's resolution is 1024 x

768 instead of 1366 x 768 due to the signal timings &/or polarity. When you are sending the plasma the 1366 x 768 signal from your scaler, what does the plasma report for the Horizontal & Vertical signal timings & polarity?



Can the CS-2 modify horizontal & vertical signal timings & polarity ?

Off to the CS-2 users manual i go ........
