    Posted: 06 August 2020 at 14:12
I've just purchased a very nice A99 body as upgrade for my A850. Had to bite the bullit an the EVF eventually. And since prices have droppen around 600 euro's took the step.

Although I'm impressed by the overall improvement on look and feel I also run into an general issue with the EVF. I can notice the refresh rate of the EVF as a continues vibration. Anyone of you have the same issue? Is there a way to increase frequency?

I know this might be an odd thing for me alone since I know I'm very sensitive to this. Back in the days when CRT monitors where running at 60Mhz I also noticed the same vibration while most of the users didn't. Solution was always to put them at at least 85Mhz when the videocard could manage it. I hope the same is possible here.

Sorry you've had no response to your question. I've looked at a number of sources and, so far it appears that there is no way to increase the refresh rate on the a99. I can share with you that this is not something that I've experienced with the a99, though I have had the experience with older CRT monitors.

Do you experience it in all cases, or mostly under artificial light?

Wish I could offer you some solution.

The a99 I think has a refresh rate of 60hz only. The a99ii can select from 2 different refresh rates 60 and 120hz I think.

That is annoying. I do not have this problem with any of my EVF's, but I notice it when the starter of a fluorescent light is going out by the flickering nobody else seems to notice. The difference might be 50hz for the mains and 60hz or higher for the EVF's. But I understand how annoying it is!

Like the others, I think the A99 only has a 60hz setting for the EVF.

I cannot find any source stating the A99m2 has a 120hz refresh rate for the EVF. It has a "display quality" setting that changes the display quality from standard to high at the expense of shorter battery life. Maybe somebody has a source telling us what it does? Like I said, I could not find it.

Thanks for the replies. Seems I have to live with it. Most noticable with bright sunny backgrounds like skies. Think I will hopefully not notice it after some period of use.
