    In my office I want to get a big TV for the meeting room that anyone can come in with any laptop and very simply be able to screen share to.

    • Has to be wireless
    • Has to be possible from any laptop old / new etc not driver dependant
    • Would really prefer to not have to install software
    • I would be happy to buy a device / media streamer / something with a USB key you could put in the laptop and just share with
    • Have looked around a lot and most things reference video streaming or viewing folders of images, I need to just screen share for PowerPoint or documents etc.

    2 options, both require installations:

    • AppleTV and Airplay (free from Mac, you need to pay to get this working on Windows)
    • Miracast - comes with some TVs, still - you need to install drivers. Windows 8.1 comes already with Miracast.

    There is this as well but it will require connecting transmitter to teh laptop which you want to project from: Wireless HDMI Few different products are available and reviews are mixed.

    Soon you will be able to get Airtame - no drivers, just a dongle. Should work from any HDMI connection.

    Some people had success with mirroring desktop to Google's Chromecast - google it ;-)

    video - Unreliable HDMI from Gateway Laptop to Pioneer HD TV

    How to improve reliability when connecting Gateway M-1618 laptop with a Pioneer KRP-500M TV using HDMI?

    Problem is that HDMI connection dissappears every minute or so for about 1-2 seconds. That is TV goes blank. This happens when using resolution native to laptop 1280x800.

    What I have tried:

    • switched HDMI cable (no improvement)
    • tried both HDMI connections on TV (no improvement)
    • switched display mode to HDMI out only (blank laptop screen) unsure if this helped
    • changed display resolution to 800x600 (this seems to help, but is not optimal!)

    Specs: Laptop Gateway M1618:

    • graphics ATI Radeon X1270 256MB hypermemory
    • native resolution 1280x800 (WXGA)
    • HDMI 1.2

    TV

    • Technology TFT active matrix
    • Resolution 1920 x 1080
    • Display Format 1080p (FullHD)
    • 2 HDMI connections (19 pin Type A) unsure what standard it supports

    My theory is that something can't handle larger data streams that 1280x800 provide (as opposed to 800x600), or there is some sync problem. TV plays Blue Ray fine, so the problem more likely is with laptop.

    Hoping someone more experienced with HDMI can provide some ideas to try.

    Looks like in the specs for the TV it will handle 1080p which is 1920*1080 progressive; your notebook video card should support this output with it's drivers especially if you are using an HDMI cable; I would force this display setting and check it out.

    Also do you have actual HDMI output from your card or are you using DVI-I as most cards have not not the DVI-D (which is true HD ie HDMI=DVI-D)

    If you have a DVI-I and using an adapter to HDMI then you loose quality but you can use an adapter from DVI-D (dual link) to HDMI with same-same compatibility

    If you are using HDMI output dirrectly than there is no worry; just check the above.

    Hope that helps!

    Have you updated your video driver on the laptop?

    .

    "Hypermemory" is shared main memory, be sure it is set to use all 256mb of shared memory.

    Some systems you can change this shared setting some you cannot, check the bios and video properties.

    You may have to change the hertz setting (refresh rate) in video properties when connected to the TV.
