My 5770 is struggling to play HD on my Benq G2420HDBL 24".
I dont know whether its the monitor or the graphics card.

My 9800GT plays HD better but it still very low FPS on same monitor. Im useing the 10.3a drivers for my ati card.

My spec
MSI GD65 1156
Core i5
gSkill Ripjaw 4gb DDR3
ATI 5770


Im useing iTunes, i downloaded BBC HD Planet Earth.

hmmm my 5770 eats HD content no probs, havent downloaded and tried to playback via itunes though, I have no issue with x264 .mkv/.avi, WMV-HD, MPEG2 HD etc. I also run blurays through my player in powerdvd and everthing is fine. I doubt the card is limiting you here.

I'm guessing but it maybe more of a itunes playback issue.

maybe try alterantive HD sources like the wmv samples on the microsoft webbie or some decent x264 alternatives, I think you can get 1080p trailers in that format.

I also use VLC for all media playback, I know that wont help you with itunes downloaded content but for other HD content it's a better performer.

iTunes downloaded the file as a MKV, VLC keeps crashing when i load it.
I tried a few sample HD videos what i got with windows 7. 720p seems to run fine and smooth (but its a noticeable difference i quality, 1080 is a lot better) but 1080 seems to slow.

Its the same with youtube, on youtube trailers i always use 1080p when available (toy story 3 for example). I got horrendous amount of lag

Ill try a few programs, recommened any programs that will play MKV? WMP, VLC dont recognize it.
 
ok i just tried quicktime player to play the video. a lot better but when theres slow camera movement (panning across landscape) thats when i start to notice abit of lag. But its a lot better than itunes playing it, its not laggy when i see animals moving anymore.

Is it lag or a mismatch in frame rate v refrash rate i.e video at 50 and monitor at 60? Have a look at MPHC for playing the files.
 
This is very strange ... everything in your spec should be fine for HD playback. I really dont have any issues with my 5770 playing back any HD content at 1080p.

granted Im running an i7 at 4.2 with 6gb of ram but watching HD content dosent seem to tax my CPU at all .. an I5 is more than enough CPU power.

just as a note from memory .mkv is the wrapper but the codec is X264. I also have x264 HD content as .avi, .mp4 and .flv . WMV-HD is a seperate codec again and also mpeg2 can output in HD as Bluray compliant and also there is AVCHD. Just to recap at some point or another I have used all of these formats with no issue on my 5770.

Like I said I can playback all forms of 1080p content with the exception of not testing itunes downloads and I have not had any issues so I would be more inclined to say the issue is either with itunes or else where in your setup.

I haven't got any footage from Itunes to test but if its anything like there music I'm sure there is some form of DRM protection preventing playback outside apple software.

Just out of interest have you run any benchmarks like 3dmark maybe? that will tell you if your graphics card is performing to speed as it could be as simple as your PCI-E settings in your bios bottlenecking the card.

best test to check for hardware acceleration is to run the video clip and open the Catalyst Control Centre (overclocking tool which will give you realtime ram and GPU usage and speed) at the same time to see if you are taxing the card, also keep an eye on your CPU process. That will tell you if the card is being used to accelerate the video.

Something I have done was to also install the cccp codec pack (combined community codec pack) as it installs the latest versions of all widely used video and music codecs.

maybe worth a try

hope this helps

just as a thought ... I would be very suprised if your monitor is the cause also, you say it has a refresh rate of 60Hz ... should be more than enough to playback HD.

Just as a check is your desktop res 1920x1080 or higher?

The video is ment to be played at 60 and my monitor is at 75 but not way to adjust to 60

hhmm try the guru3d webbie ... I think the app is called rivatuner? I lose track cos the names change every other release. Anyway you can force refresh rates using that but again I pretty sure having a refresh of 75Hz will only improve video quality and not have a negative effect.

i was thinking of trying that with an old monitor but i heard a lot of bad reviews for it. Will it damage my monitor?
 
I would say yes if your forcing higher refreshes and resolutions but you should be ok dropping from 75hz to 60hz ...

that is a best guess though so if your worried about damagin the monitor I wouldn't play with the refresh rates or resolutions outside of what is available by default.
 
I got abit further. Quicktime isnt as bad and itunes is just the same. Must be the program issue not hardware/driver issue. Ill try and find a HD movie whats in another format and compare.
