MDP to HDMI - Quality Issues

I just recently purchased a MDP to HDMI for my MB. I am using a Vizio 32'' and the quality of the output is horrible. I don't know what could be the issue?

Hi Anxious,
You indicated that you bought a Mini DisplayPort to HDMI adapter, I take it through a 3rd party vendor? As Apple only makes MDP to DVI and MDP to VGA. I too have a Vizio TV (42") and I went the route of MDP to DVI and then a Belkin DVI (Male) to HDMI. I've been extremely pleased with the output. One thing I've noticed with the Vizio TVs (due to their price) is blacks and bright colors need to be tweaked via the TV's setup menus. Otherwise the colors look very washed out, the whole picture will look dark and you'll get a significant loss of detail. The contrast ratio and shades of black are definitely a weak point of the budget brand.
I too tried a MDP to HDMI for NewEgg.com and the adapter was total garbage. The first one didn't work and the second one gave me fuzzy images (at any resolution) and terribly washed out colors. The only reason I knew something was amiss is because I had the MDP-to-DVI-to-HDMI setup to compare the output against.

  • MDP to HDMI video issues

    I've installed windows 7 on a Macbook because i love the total war series. I'm trying to display the screen on my 50 plasma over MDP to HDMI connector and am unable to see any video. Windows doesn't even detect that I've plugged in the TV. When i use the mac OS, it works fine. Any suggestions?
    Thanks.

    Sounds like you may have been in extended display mode. If so, all you had to do was drag a window to the projector display. Or, if you wanted mirrored mode, in display preferences select check mirror display.

  • HDMI doesn't work, but MDP- DVI- HDMI works

    Hello!
    I just got my new Mac Mini and tried to connect it to my TV (a Samsung LE22S8) over HDMI, but this doesn't work since the TV reports "unsupported resolution" (it's the TV's native resolution of 1680x1050, where I also checked all frequencies using an external program and they are as written in the manual of the TV).
    However when I connect the TV over a Mini Display Port to DVI adapter, and then use a DVI to HDMI adapter (so that the TV is still using the HDMI input) it works fine.
    So what's the difference between MDP->DVI->HDMI and HDMI->HDMI (all resolution and pixel frequency settings are identical)? What can I do to get the HDMI->HDMI solution working?

    It also appears that there is no conversion when HDMI-video is extracted from DVI, only that the pins are shuffled.
    If direct DVI works on that port, then HDMI-video with an adapter should work as well. As I mentioned above, VGA is present on DVI-I ports on a separate set of pins, and VGA working or VGA not working has no bearing on your problem.
    If a Mini DisplayPort is involved, the most common issue is that the Mini DisplayPort connector is not inserted firmly enough. It has a lot of pins and you have to press hard to seat it.
    Other possibilities are that the resolution you selected is beyond the capability of the display device, or that the adapter is bad.
    Is this the stock display card, or one you added later, and what model?

  • I have a 2011 i5 iMac and I am trying to connect it to my Samsung PS50C680 Plasma TV. I am using a MDP to HDMI cable and using HDMI 1 which is the correct input according to the manual. No matter which I turn on first the iMac still cannot connect.

No matter which I turn on first etc the iMac cannot find the display and the TV shows no signal. Has anyone else had a similar problem? Any help would be appreciated.

  • IMac 2011 Thunderbolt - iWires MDP to HDMI

    Hello all - I've had a good trawl through the communities and am unable to find a fix for my issue.
    I've recently upgraded from a 2010 mac mini, with HDMI to a new iMac 2011 - which has the new thunderbolt port.
    By my understanding, this will enable me to use the Thunderbolt Port - identical to the old Mini Display Port to output HDMI to my HDTV.
    I've bought a MDP to HDMI adapter (http://store.apple.com/uk/product/H2774ZM/A/Mini-DisplayPort-to-HDMI-Cable-2m)
    But my mac will not recognise my TV, no matter which way method I use.... ie turning tv off and then plugging in to the mac..
    Do I have a dodgy lead / dodgy mac, or both!?
    My intention is to swap the lead at the apple store - and see what happens... but in the meantime, I thought I'd pick your brains!
    Cheers,
    Tom

    Fixed.... turned both the tv and the imac off and on a few times.. eventually worked and is fine now.  I can also confirm that the sound does work perfectly!

  • Second Display Quality Issue

    I have a mid-2010 iMac 27" and it works wonderfully for me. I need a second monitor to place other applications on, so I grabbed an unused Asus VN247H monitor that my son was not using. It has a 24 or so inch display and accepts HDMI and VGA inputs. I purchased an Apple Mini DisplayPort to VGA Adapter and connected the Asus to the back of the iMac. It works, but I'm underwhelmed by the quality I get on the Asus. Yeah, I know - it isn't a top-of-the-line monitor, and it is never gonna look as good as the iMac, but it isn't a $10 el cheapo, either. It is a good monitor and has a 1ms refresh rate. Anyway, no matter what resolution I try using, the output on that second display looks, well... crappy. The text letters are a little blurry, they are a lot larger than I figured they would be, and - I don't know - it just isn't what I was expecting. One thing I notice is that in the documentation for the monitor, it shows that I should be able to go up to 1920 x 1080 but that isn't the case. When I bring up the OS X System Preferences-->Displays, on the Asus VGA part it only shows a max setting of 1600 x 1200. I tried clicking that but the monitor complains and sez it's past the capability of itself. I am supposing it's because of having VGA instead of digital??
    So, I've ordered the Apple Mini DisplayPort to HDMI Adapter in hopes that an HDMI digital connection will give me better looking display and the full compliment of resolution options. Am I out in left field on this supposition? Or, is there some other thing I've not thought about in order to get a sharp looking second display?
    Thanks, Jim

    Well, after four days, there have been a grand total of ZERO replies to this post / question. Either my question was lame, or no one else has run into a second monitor quality issue. At any rate, I'm answering my own posting - perhaps someone, somewhere might run into the issue and come across this information.
    The answer to the question is: YES, changing to an HDMI connection between the iMac and the secondary monitor made a HUGE difference in quality. Why I went with a VGA adapter in the first place is unknown. But the HDMI connection is for sure the way to go. Colors look good, text is "almost" as good as on the iMac.
    Problem solved.

  • Flash PLayer Audio Quality Issue

    Howdy,
    I am having a strange issue where I am hearing quality issues in the playback of sound on any flash content (youtube etc ..). The background music or backing tracks all play fine, but the Vocals / Voices in the video are quiet and distorted.  The best way to explain it is, that I can hear the music on a music video ... but the words that the artist is singing aren't there.
    Strange ....
    I am running Windows 7 64-bit prof. on a brand new machine.
    i7 X980X
    12 gig memory
    Realtex onboard sound from an EVGA X58 motherboard.
    I have tried clearing and re-installing the installs, codec packs ... etc ... additionally this problem is present any time I play flash content in any browser or with a stand alone flash player.
    Also, my sound works fine in games and local audio. And it passes all the surround sound tests, so I am sure the cables are hooked up appropriately.
    Any thoughts ?
    Thx !

    Sadly, none of those seemed to help.
    I was able to track down the issue. I have a new graphics card, and GTX 580
    with HDMI support. It also installs an audio driver so it can pull out the
    audio and send it out the HDMI port to a monitor with speakers / TV .. etc.
    Once I disabled those drivers, everything started working normally. It was
    some very strange symptoms.
    Thanks,

  • Canon Vixia HFM40 video quality issues in Premiere Elements 10

    Hi,
    I am trying to edit video from a Canon Vixia HFM40 camcorder in Adobe Premiere Elements 10 on a Mac, but the video playback and the exported video has quality issues.  Playback is not smooth when there is a lot of movement in the picture.  It looks similar to interlacing issues, but there are no horizontal lines when the video is paused.  Any ideas on how to solve that would be be much appreciated.
    Here are the specs:
    Video Format (Canon's XFP mode):
    - AVCDH MPEG-4 AVC/H.264
    - Resolution: 1,920 x 1080
    - Bitrate: 17 Mbps
    - Frame rate: 60i or 30p (problem occurs in both instances)
    - File extension: MTS
    Workstation:
    - Fall 2010 27" iMac, quad core 2.93 GHz Intel Core i7
    - Mac OS X Lion 10.7.2
    - 12 GB RAM
    -  Adobe Premiere Elements 10.0
    Project Preset: AVCHD Full HD 1080i 30 (several other presets had the same result).
    Thanks.
    Ralph

    OK, I've been doing some more research and I think I found the problem.  The choppy picture is due to Premiere Elements and VLCs inability to properly de-interlace the 60i video.  It gets played back in 30p, which does not create horizontal lines, but it is a lot more choppy than the native 60i, especially when there is a lot of movement in the picture.
    I verified this theory by installing the latest VLC beta (from http://nightlies.videolan.org/) and playing back my source MTS file with De-Interlacing set to "On" and De-Interlacing Mode set to "yadif (2x)".  Those settings did not work with the current official relase of VLC (1.1.12).  The 1.2 VLC beta is not fully functional yet and I am not getting consistent results, but when I play that video several times, then after about 3 or 4 tries it plays back perfectly smooth, just like it is when playing back the native file from the camcorder connected to the HDTV via HDMI.
    That also works with video exported from Premiere Elements 10 with preset AVCHD M2T - H264 1920 x 1080i 30.
    The video is still choppy when played back in Premiere, but that does not really matter, since the output file produced by Premiere can be played back with VLC (assuming that the final build of VLC 1.2 can handle the files correctly).
    -> Hunt: thank you again for your help.

  • HP Officejet Pro L7590 - print quality issue

    We've had a lot of problems with this unit since day one.  It simply wouldn't work with our XP computers.  Thankfully it does work with our new Windows 7 computer.
    The problem I'm having is that I have to clean the printheads at least once, if not twice, before every print job if it hasn't printed anything recently (even an hour or two).
    Although we've had the printer for a while, it has hardly been used because it wouldn't work with our previous computers (and I gave up trading emails with HP support because the situation just got worse each time we tried something, not better).  The myPrintMileage function says we've printed just over 300 pages (and I can pretty much guarantee that at least 250 of those have been diagnostic pages trying to get it working, not actual print jobs). 
    The only advice I can find on the troubleshooting page is to replace the printhead/s.  Is that really the case?  We have already had to replace ink cartridges before we ever got the printer working.  If we now have to replace one or both printheads this machine is proving very costly to run.  I would be very disappointed to find we had had to replace all four ink cartridges and both printheads before we ever got the machine working properly. 
    I'd appreciate any feedback you can offer on this please.

  • Iphone 6 call quality issue....

    Hi, yesterday i saw software update in my iphone 6 and i thought it will solve the call quality issue , but unfortunately it was not for that.
    Dear iphone support , the call quality in iphone 6 is really bad, I was using iphone 4S and that had great voice quality. iphone 6 voice during call is not clear , it has noise .
    When I told my friends about the problem , they told me that I might have bought the refurbish phone. But I bought it from Dubai in 750 USD and I do not think it would be the case.

    Since my iPhone 6 has great Call Quality,
    My tip would be to take it to an Apple shop. All apple Products have world wide warranty.
    If it is really they should be able to fix it.
    Hope this helps,

  • Print quality issues

    Hello
    We are having print quality issue when printing PDF's to our Canon iR C2880/C3380 UFR II.  This was the most recent print driver from canons website which was download about 6 weeks ago. version 2.9.  At one time we were having other pring quality issues and we changed from the post script driver to the ufr ii which solved the problem at the time. 
    This past saturday we upgrade the operating systems on the systems in question and they are now running windows 7 64 bit with service pack 1 installed. image 1 is the orignal pdf that was printed with a 3rd party pdf printer(PDF Xchange view version 2.5)  image 2 is the same document that was printed using acrobat reader 10.1.2
    the options for the print were pretty much identical between the program.  Print as image was not selected.  1 thing to note with the acrobat when  print as image was selected there was a slight improvement in the print quality.
    Any help would greatly be appreciated.

  • Has Apple addressed poor sound quality issues with new 160GB iPod classic?

    I just bought a new 160GB iPod classic, replacing a perfectly good 80GB iPod Video (5.5), thinking that the newer one would be superior to my 3 year old model. I discovered that the sound of the new unit was flat and muddy compared to the older model. I found that the 5th gen iPod video was more "spacial", if that's an appropriate word to use; the bass was more present and more clearly defined, as was the rest of the sonic spectrum. I searched several forums to research this issue and while there were numerous references to this issue, all of the posts I found referred to the original iPod classics (80GB and 160GB) and not the later 120GB classics nor the new 160GB classics like the one I bought. Has Apple done anything to address this issue since the first classics were released or are the new ones still suffering from the same sound quality issues as the original classics?

    Based on your observations here, they apparently have not changed the sound quality since the original 160GB classic. I noticed a clear narrowing of the sound stage (ambiance) between the 5.5G 80Gb and my 6G 160GB. You're describing the same characteristic. I don't own the newest 160GB version and came here today to see if it might have improved the sound quality back to the 5.5 spaciousness. Note that the 5.5G has a higher signal to noise ratio than the 6G, making it difficult for me to enjoy it through efficient balanced armature in ear monitors like the Shure SE530s or Ulimate Ears Triple.Fi 10s.

  • Hp Color Laser Jet 5550dn Print Quality Issues

    Good Afternoon,
    I have a Hp Color Laser Jet 5550dn that has some print quality issue.  I've attached a black and white scan, but the color is a light blue to blue that form the blotches.  On the back of the page there are blue and pink streaks.  
    I can print more sample pages or print them in color, but anyone have any idea what could be going on here?

    We are encountering a similar problem. The streaking is coming fromt the Cyan cartridge and has continued for over a year now, despite numerous cartridge changes and replacing the transfrer case. It is progressively getting worse and I have yet to find a solution to this problem online. Any help or guidance would be appreciated.
