Older HD tvs and HDMI

I have a 2 year old JVC HD TV and the HDMI port doesn't seem to work with with any of my apple products. Called JVC and they don't cop to anything. They say they have never tried to hook-up any Apple stuff yet. I have noticed some other info of similar problems the older HDMI ports with home entertainment systems. Right now I am using component cables and plan to try HDMI to DVI to VGA port on JVC. Is there any other way to use HDMI with older HD TVs? The JVC is seeing something there on HDMI but seems to be having a resolution issue that prevents video. I will have to check to see if audio is working today, for some reason I think it is. Am I loosing any HD quality with my component or DVI to VGA work around ?

JVC may be passing the buck here. HDMI is HDMI regardless of who's equipment you are using, v 1.3 is backwards compatible with earlier versions. The only question you need to consider is whether the HDMI on your tv has HDCP, virtually all do but not all. If JVC haven't added HDCP support to HDMI then I'm afraid it won't work.
Unfortunately, your alternative suggestions are even less likely to work since DVI quite regularly has no HDCP support.
I'd confirm with JVC whether your HDMI connection has HDCP support and if so I'd be asking them to fix things, although that may be a little difficult after 2 years. I'd also ask them about DVI and HDCP, I suppose there is is the chance that they made both HDMI and DVI HDCP compliant and that you simply have a broken HDMI card.

  • Can i use both Component video and HDMI?

    Hi guys,
    Im wondering if its possible to connect both Component video and HDMI on the ATV?
    Its currently connected to HDMI on our main HD TV, however, the apartment we have has a strange setup in which you must send RF signals to a loop back in the main room to reach all other TV's.
    We dont have the capital for either another flatscreen TV or a second Apple TV until next year - so currently we've got an older (see 2004) bulk of a CRT TV upstairs and my thought was i could route a signal to the RF loop back from the ATV and use my iphone remote to control what it plays to view upstairs.
    For this id need a component to composite/rf convertor which ive found so sending the signal is no problem, but what would happen if i were to connect component cables as well as the HDMI, does the ATV output on both, or priortise the HDMI?

    When both types of cable are connected to the tv at the same time, the HDMI connection will be on by default but the component is turned off... and what happens if the source to the HDMI cable is off - eg its plugged in but its got no where to send the signal, would it still not send to the component?.. You mean if the tv was off, same thing, HDMI would take precedence.
    Are you sure about this, Winston? I have only 2 component (and 2 HDMI) inputs on my Panasonic HDTV. For this reason I invested in an Audio Authority Component Switcher (Model 1154A) a few years ago. When the TV device arrived I connected it directly to the HDTV via my HDMI-2 HDTV input and also connected the component video and optical audio to the switcher. I have no problem using the HDTV's input selector to switch back and forth between component and HDMI lines. While I admit I cannot split the screen between an HDMI input and anything else for simultaneous viewing, I can leave both lines plugged in and switch between the two lines. In addition, the activity light on the switcher indicates there is a signal present on the switcher even when I am watching the HDMI line. (Of course, this may simply be triggered by the switcher's optical audio signal since I normally watch the TV video via the HDMI line (with HDMI audio muted) and use the optical audio line to drive my receiver's AC3 decoder so I can enjoy 5.1 audio with my latest conversions.) Am, therefore, wondering if the OP may have the same capability and could then simply switch to a different input mode to "de-negotiate" his HDMI connection and allow access to whatever component device he needs as long as he doesn't need simultaneous viewing on both TVs.

  • Pb screen fuzzy plugged with mac mini and hdmi cable

    Hi all, I bought my first mac yesterday and I plugged it it this morning on my tv screen with an hdmi cable. I saw that the screen at the bottom where all the icones are is fuzzy. We set it up at the apple store and it was working well. Could you please help me.
    Thanks a lot for your answer

    Well, here's to a happy conclusion.
    After bugging the local electronics store for two days in a row, I've found a working Full-HD TV.
    Lessons learned:
    a) Be thankful for stores where you can bring in your own computer and hook it up to the TVs on display.
    b) Don't just glance at the manual.
    After trying several TVs and not getting any good picture by either connecting by VGA (consistently showed slight ghosting with high-contrast colors) or HDMI (all TVs did cut off Dock and menu bar), neither the salespeople nor I had any idea what else to do.
    The next day, it hit me: We had tried all kinds of setup/config selections from the TV's setup menu.
    What we did NOT do was to simply try it with the "Zoom/Aspect" button on the remote - partially because that didn't work with the first model I bought.
    So, Mac mini back into the suitcase, back to the store, "Ah, you again...", hook up the first TV set, press "Zoom", pick "Truescan", press "OK" -
    Problem solved. Pixel-perfect alignment. => TV bought.
    Just for those looking for a "known to work" answer: It was the Toshiba, XV 500 series, older model. It's running on "1920x1080 @ 60 Hz (interlace)", but since I'm using it as a monitor, the "interlace-only" doesn't bother me too much. No problem even when watching DVDs via the mini.
    Image is stable, text is crisp and readable at 5-6 ft. distance, dimmed-down lamp is more than adequate even at minimum brightness since the room faces north. Low-power setting of the lamp makes for only 70 watts consumption instead of the rated 180+ watts.
    Happy user here now

    Having problems connecting iMac(late 2006) running 10.7.5 to a Samsung Flat Screen TV using separate audio/speaker cable and HDMI standard cable, mini-DVI to HDMI video converter.  TV displays generic Apple galaxy background and "some" windows (e.g. screen resolution choices).   It does not show Mail or Safari menus.  System preferences'  display "gathered" the Samsung and chose its resolution.  I did not find a way to select the Samsung as my display.
    In addition to having old hardware, we have Verizon FIOS providing internet and TV access.  Is there any way to make this work for us?  We would like to stream video (Netflix) and view shows from the Web.  Do we need Apple TV to do this?  Or is it not possible with our old iMac?  My husband thinks that our Airport could be a factor. 
    Thank you

    Lately, I have been seeing a lot of posts with users trying to use their Macs/iMacs to mirror their streaming video from their Macs to an HDTV.
    There are, actually, many alternatives to choose from than just from a Mac.
    You need to have or invest in a WiFi capable router for all of these examples.
    Apple TV only integrates with WiFi and newer Mac hardware. So, if you want to have total integrated experience, if you have a 2011 Mac or newer, you might as well pay the $100 for the AppleTV box.
    If you have a older Mac, like I have noticed many users do, then you have other options.
    If you want to elimate long cable clutter and having your Mac at the mercy of your TV all of the time,  you can still use the AppleTV box independently or purchase cheaper alternative media streaming boxes from Roku, Sony, Boxee or any number of electronics manufacturers that now have media streaming boxes and media streaming capability built into DVD/Blu-ray players.
    These eliminate long cable clutter by being close to the HDTV where shorter, less expensive cables can be used.
    Another alternative for iPad users is to use an iPad with the USB/HDMI video adapter and use your iPad as the streaming box. This ties up your iPad in much the same way as it does with your Mac, but again the iPad can be close to the TV and use minimal cables to the TV.
    Another alternative to is to use a combination of an iPad and your Mac to stream content that is only available to stream online from a computer. In this case, you can use a desktop remote app on your iPad and Mac. A good and cheap Desktop Remote app is Splashtop Remote. This allows you to completely connect your iPad remotely, over Wifi, to your iMac desktop. The app streams both video and sound to the iPad which is still connected to your HDTV. The resultant stream video picture will be smaller than the size of your HDTV, but it will still be plenty large enough to watch. Again, if you own a iPad and an Intel Mac, this method also allows minimal cabling to the TV.

  • Is it possible to show a presentation from the original iPad via wireless on an older projector with no HDMI input?

    is it possible to show a presentation from the original iPad via wireless on an older projector with no HDMI input? If so, what equipment is needed?

    The ipad not support wireless projector yet.
    The workaround is you are using computer that connected wirelessly [needs 2 wireless adapter] / via cable to projector and connected also to the wireless router.
    You are controlling the computer via wireless connected to the router using remote desktop app like splashtop, teamviewer, logmein, vnc, etc. You must set the remote desktop port and app at the computer too as ipad app support.

  • VGA and HDMI

    I am going to buy a new monitor. My firend suggested me to buy a TV instead. I have an ipad 4 and a macbook air. I also have lightning to VGA and mini display to VGA. Most of the TVs have HDMI input not VGA. I am planning to get a VGA to HDMI converter to fix it. Will it work?

    Instead of getting a VGA to HDMI converter, get a Mini DisplayPort to HDMI adapter and a HDMI cable, so you don't need a converter and there are more chances to make your TV work with your MacBook Air. See > http://support.apple.com/kb/HT4241
    The main benefit of using HDMI is the possibility to use a HD resolution on the TV if it allows you to use one of those

  • Can I connect two 4k TVs and one additional monitor via DVI to my MacPro (late 2013)?

    Can I connect the following?
    - 4k TV via HDMI
    - 4k TV via Mini DisplayPort with an HDMI adapter
    - DVI monitor with 2560x1440 resolution

    I saw this page before but I am not 100 % sure if I interprete the statements correctly. For example, it is stated that "Two HDMI (HD or 4K) devices" are supported. When reading only this, it seems that the configuration in my question is not supported. However, they also wrote:
    "Mac Pro supports a total of two DVI or HDMI displays when connected via the built-in HDMI port or using the Apple Mini DisplayPort to DVI adapter. To connect additional DVI displays, use an active DVI adapter such as the Apple Mini DisplayPort to Dual-Link DVI adapter. You can connect up to six active adapter DVI displays. This requires a powered USB hub since Mac Pro offers four USB ports and you will need six to connect them all."
    Does this mean that I can also attach additional 4k HDMI TVs (and not just DVI displays)?

    Sounds like you'll need to access that drive while it is not booted. You need to replace it anyway, so do that, then one way or another (ext enclusure, et), access it and copy files.
    If you keep trying to boot it, you might kill it for good and not get your files, so just swap it out first.

  • HT1386 I have an older iPhone (3gs) and need to upgrade to a newer phone (4S).  I need to get my NOTES, CALENDAR, CONTACTS, PICTURES, etc backed up on iTunes so I can get that data loaded onto the new phone.  But not sure how to do that.

I'm assuming it's trying to tell me I have an older iTunes Library, but don't know that.  Geez, maybe people over 60 shouldn't have iPhones, iTunes just bafles me.

    Are you wanting to import iCal to the MacBook Air. Since iCloud doesn't work with 10.6 OSX you probably don't have any data in iCloud yet?

    can it be something related to wi-fi?  I have read other posts talking about loss of connection using wifi.  I'm connecting my G5 through an airport express which is expanding my wifi generated from my Apple Time Capsule. It is quite difficult for me to relocate the server close to the Time Capsule and vice versa but if it works, at least that would be something.  It was working with Lion about 3 months ago - showing up in Finder, etc.

  • I've an apple ID used to buy off iTunes and a mobileme account for the calendars and contacts. How can I move the calendars and contacts to the older apple ID and use it for iCloud?

    I've an apple ID used to buy off iTunes and a mobileme account for the calendars and contacts. How can I move the calendars and contacts to the older apple ID and use it for iCloud?

    If you remeber the password to that Apple ID then follow these steps
    1 - Make sure you have an email address that is NOT an Apple ID
    2 - Go to AppleID.Apple.com
    3 - Where it reads Manage Apple ID - Sign in
    Once you are signed in want to make sure the email address you are wanting to use is NOT set up as a "Recovery/Rescue" email for this account.
    [To check this - Main page where you see Primary ID - below do you see the email address you want to use listed towards the bottom? Yes - Delete / No - Good ./. If made any adjustments "Save" Next on the left select "Password & Security" - Answer your security questions you set up "if you have any" then scroll towards the bottom and check to see if you see the email address you want to use. Yes - Delete / No - Good] <-> Also you can change your password on this page as well. Any adjustments made "Save"
    Once this is done go back to the main page where you should read "Primary ID" and change the email address that is showing to the new email address youo want. "Save" Done
    I learned this not to long ago and worked for me. Hope this helps you!

  • HP Pavilion dv9218tx Notebook PC and HDMI audio problem with Sony TV and Windows 7

    Sound does not come through with the HDMI connection and, on investigation, there is no HDMI audio driver/option.
    Noting that there seemed to be an issue with windows 7 and HDMI audio which is addressed by updating the BIOS and the connexant sound driver I have done so to no effect.
    The Sony TV is recognised as a standard monitor in the devices for graphics but not for audio
    Suggestions as to why HDMI does not appear - including as a disabled service - and what to do t get is available?
