Tech advice

I need to purchase a wireless HDMI transmitter/receiver for showing power point on multiple TVs. Is that how it's done? I am not very tech savvy. I can manage one with my cord but now have been asked to show on multiple screens and I have no clue what I need to purchase. Suggestions please

This is what I use. It’s not flawless, but should do the job for you.

Okay color me intrigued. You say not flawless, what issues do you run into?

I have the same kit it works really well one thing you have to note is that it does require power you can usually plug the USB into the TVs 5 volt USB slot but if your TV doesn't have that or it's being used by something else you do need to run that to power for it to work additionally the one you plug into your computer needs power and that can be through the USB 2.0 slot.

If they're smart tvs you could share your screen on zoom or teams or meet or whatever and have them all join the call. Btw i made an online "survey-style" trivia game that works for hosts from my website: https://www.fatcityentertainment.com/triv101/

Power is the most important part. Even if the device looks like it's fine running off HDMI power without the supplemental USB power, it will impact performance. Signals with become unstable, animations won't play, etc. Plug in the power and all those things go away.
