Looking for some advice.

Our church is moving in to a new facility and we are going to use a pair of TV's instead of screens/projectors.  (We are doing this because of ceiling height)  Do any of you have experience with using wireless HDMI or built in WiFI in a smart TV to connect a laptop for video/powerpoint.  I've looked at a number of wireless HDMI options but the trick here is that I need 2 TV's to sync to the laptop not just one, and the only wireless with multiple receivers costs as much as a TV.

I am hoping to do this via a wireless option because of the cable path that would be required.  The transmitters/receivers for wireless HDMI or WiFi would be less than 50' away and we have not purchased the TV's yet.

Any suggestions?  Or experience as to what works/doesn't work?
Thanks.

I try to use as little wireless anything as possible for a permanent installation.  Especially in a church. Hard wire it if you can. Cuts down on interference issues that may crop up. Much more reliable. IMO

If your cable run is not too long, I would get an HDMI splitter then convert to Cat5/6 then back to HDMI at the TV's.

This has been working pretty good for me

I have had a few dropouts but I'm in a noisy enviro. Nothing major though. I would go hardwired if I had a critical application but we just use it to play movies at the resort during holidays.

The price on that is more than my projector. Ouch!

As someone suggested, Teradek Bolt line is THE ONE, but it's pricey.

I was using Nyrius Aries Pro at one point.  It would work fine 50ft when room was empty, then when all the guests came in, it would be intermittent.

I suggest an HDMI splitter with EDID management like this:

This allows your laptop to drive 2,3,4... TVs simultaneously, without any of the handshake/no picture issue common with splitters not equipped with EDID management circuitry.

Should not have any problem with good quality 50' - 65' HDMI cables.  Any longer and you should look into HDBaseT or HDMI over CAT5/CAT6 solutions, which will be WAY cheaper than a long booster HDMI cable such as  Gefen or NTW.  You can pick up HDMI over CAT5 Tx/Rx set from Monoprice, TigerDirect, etc. for less than $50.  Works best with shielded CAT6, but I've gone unshielded less than 100' without problems.
