Forums -> UltraMon™ -> 0.5 sec lag in the mirrored second screen
Jim   2021-04-02 01:16
testing the latest version of Ultramon on WIn7 64 bit.

On the second monitor, the horizontally flipped image lags by 0.5 second.

Is there a setting so there is no lag at all so everything is instantaneous like the first screen?

thanks in advance

You can change the screen update rate on the last page of the mirroring settings wizard, by default the mirror monitor only gets updated 5 times per second.

Thanks for your reply.
I already set it to fastest refresh rate and still getting a slight lag.
Trying to game on the mirrored screen...

Is performance better if you don't have a game running? For example with something like a browser or Microsoft Word?

Even with a browser,there is a slight lag. For browsing,the lag isn't a huge issue. Wanted to play a games

I am running a two monitor setup. Trying to play a fighting game like Street Fighter 2 but in the second screen I would like to see the flipped image. I'm now running a game on one monitor and a browser on the second.
Even with using a browser and moving the mouse,the flipped image has a slight lag. I'm not running a game with a browser . sorry for the confusion.

With 30 fps I think I'm seeing a slight lag on my system when scrolling in the browser, but for example when I'm typing in an app there doesn't seem to be any noticeable delay.

Not sure if that's what you're seeing as well. In general I've seen better performance with mirroring on Windows 10 (and with recent video cards), difficult to say if this would make a difference for you.

Thanks for you suggestions.
Windows,any versions,won't do a true mirror like Ultramon. Windows "mirror" screen is actually a clone screen. There are hardware solutions but didn't want to get another piece of hardware...t4ying to keep it simple as possible.
Ultramon is great for general purpose, but for gaming that slight lag makes it an issue.
Thanks again.

To OP: I use the mirrored reverse image function to see Zoom/Teams video chat participants through a teleprompter Mirror device to be able to maintain eye contact. Just curious why you would want that functionality for game play.
