DLPLIGHTCRAFTER: Maximum refresh frequency in video mode of the LightCraft 4500

Miezekatzen Dompteur

Part Number: DLPLIGHTCRAFTER

Hi...we use the LightCraft 4500 in our project...the LightCraft 4500 is connected over HDMI and we drive the LightCraft 4500 with 800x600@60Hz-24Bit color depth...now the LightCraft 4500 is in video mode...is it possible to switch the LightCraft 4500 in a mode that we get a refresh frequency of f > 240Hz...?? Is it possible to decrease the color depth, perhapse to 2 Bit color depth and increase the refresh frequency to 240Hz...the interface frequency of the HDMI connection is the same 800x600@60Hz...a FPGA board drives the LightCraft over HDMI...Have a good day...Bye bye

Hi Miezekatzen,

For clarification, do you want to drive the LCR4500 in pixel accurate mode? Asking because if you feed 800x600@60Hz stream to LCR4500 it will not be in pixel accurate mode as HW upscaling will be happening. If you want pixel accurate mode you should only feed patterns of native resolution i.e., 912x1140.

Awaiting response.

Regards,
Hirak.
