HD Graphics 4600 abnormal refresh rate limitation

BFoll1 — Tue, 05 Jun 2018 18:20:16 GMT

Hi everybody,

I am doing an experiment in my lab.

It´s a rapid serial visual Presentation protocol which needs a high and efficient refresh rate to present very high velocity stimuli (<10 milliseconds).

My screen is featured by a 144 HZ refresh rate but my experiment software indicates clearly a 60HZ limitation.

I've done the updating of the graphic card and I have a HDMI connectic but the problem persists.

Please could you help me to fix it ? I need to improve my refresh rate imperatively to do the experiment.

Thanks

Brice

Hello Diego,

Thanks for your answer.

It's possible I have found the nature of the issue but I have to test it.

I have seen in the forum it is probably due to the connectic.

Indeed, the HDMI cable seems to not allow a higher refresh rate than 60 HZ but with a dysplay port it could work.

I am waiting for this cable to do test and check it.

The best,

Brice
