    Question Monitor - HDMI from PC to TV

    Hi Guys

    I hope you can help me to solve a problem that have occured after I installed Windows 8 Consumer Preview. A couple of days ago, I wanted to connect my Acer Aspire 4820TG laptop to my TV with a HDMI cable, but nothing happend. My PC doesn't react at all, and the TV screen remains all black. Before I installed Win 8 CP, I had Win 7, and the connection worked flawless. My Graphic Card made a change and "bing" my desktop was dublicated to my TV screen. My graphic card is a ATI Mobility Radeon HD 5650, and i suspect that it may be a driver which isn't working properly. But I'm not sure, and I can't identify wich driver it is ?

    I really hope that someone can help me with my problem, and i hope you have enough information to identify my problem.

    Thanks

    Best regards
    Mads

    Hi Mads, AMD ATI Mobility Radeon HD 5650 is fully support for playing all HD videos since it supports Avivo with low wattage (only 10w-15w). Actually AMD ATI Mobility Radeon HD 5650 is just equal with AMD Radeon 5570 of Desktop.

    I hope you did not replace your Win 7 installation, but dual booted the Win 8 CP into a second partition alongside Win 7. Win 8 CP will deactivate in October when the Win 8 RTM is released. It is time limited.

    Since this is a beta OS there is no guarantee that all the features of Win 7 are present yet in Win 8 CP and in fact many are indeed missing. For this stage of development Win 8 CP is surprisingly smooth and complete, but is still lacking finishing touches, and that may very well be one of those finishing touches that is lacking. You might be out of luck.

    Default Re: Monitor - HDMI from PC to TV solved

    after a lot of messing around and rolling back drivers and installing new drivers from microsoft and asus (I have a zen ultrabook ), I finally stumbled apon the fix for getting the hdmi output to work!!
    the trick is to go to the settings (right flick on the mouse pad) choose devices the go to "second screen" and then while plugging in the hdmi cable at the same time with the mouse choose the connection you want, either duplicate, second screen only, extend or pc screen only.
    Apparently the connection is recognized when you click on a choice WHILE plugging in the hdmi cable. I've had 100% success using this method while it would only connect one time out of 20 when just randomly plugging in the hdmi cable. Very strange but it works. Have not found this work around or any other solution for that matter anywhere else. Don't post a lot, but noticed that a lot of people were having problems with this connection. Now if only I could figure out why I have no sound on my youtube videos when going back into my browser having been listening through my bluetooth speakers before and then having them off when reviewing youtube videos. I have sound if I turn the bluetooth speaker back on, but nothing when I turn them off!!?? The only solution I've found is to do a reboot, or reload chrome in desktop version or vice versa relaunch google chrome in windows 8 mode. That will usually get my sound back in youtube videos over my asus zen ultrabooks internal speakers.
    I'm sure there are lots of other bugs to be found, but so far these have been really "bugging" me
