Tool/software:

Hello.

I can't get the DLPLCR4500EVM video mode to display at 120 Hz. Could you please tell me how?

I'm using Windows 10 Pro and a GeForce GTX 1660 Ti video card.

I want to display at 120 Hz, but when I try to set it in the OS display settings, I can only select 60 Hz.

The current settings obtained using the Control Software are attached.

I checked other threads on the bulletin board, but some links were broken and I couldn't figure out how to set it.

Could you please tell me how to display and use the GUI for settings?

Thank you in advance.

Hello Atsuo,

Please see the following thread. It has the latest information on this issue:

https://e2e.ti.com/support/dlp-products-group/dlp/f/dlp-products-forum/1350509/dlp4500-is-120hz-video-mode-supported

I regret to inform you that it appears that the DLPLCR4500EVM does not work correctly with 120Hz and at this time does not appear that any fix is planned.

Thank you.

If the DLPLCR4500EVM can update the screen at a frame rate of 90 Hz or more,
the flickering that occurs when the screen is updated can be sufficiently suppressed.
For my application, as long as flickering can be suppressed, an update frequency of around 10-15 Hz for the image itself will not be a problem, so the problem has been solved.
