Graphic Cards HD4000 RIG connected to LG 47" LED Strange Problem

[terence_fdes]

What is your intel driver version? Could be an issue with that if its not the player.

All drivers & BIOS is the very latest on my system

custom sync settings dont work if EVR CP is selected in output. it works only if sync renderer is used.

Ya ... I remember that "sync-renderer" needs to be chosen & did that too earlier ...... [of the quick glance that I had of the user-guide tutorial ...... but that thingy is missing today]

hi terence_fdes, are you aware of the 23.976 Hz issue with Intel ?

please read this, dont know if it is helpful 23.976 Hz video output issue still not fixed in Ivy Bridge? - AnandTech Forums

THIS IS INDEED NEWS TO ME ...... and very interesting. Although the discussion is dated (before Ivy's release) and will need to dig deeper ..... Over 95% of my movies are at 23.976
Was this fully resolved after Ivybridge was released ???

Allow me to use just two of the quotes from that discussion .....

Well, either it works or it doesn't. If Intel has improved it with Ivy Bridge so that it stutters for example only every 30 minutes instead of every 5 minutes then I think it's still unacceptable - it will still take focus from the movie and I will be counting the minutes until the next stutter occurs.

Finally, does anyone know why it technically is so hard to produce a proper 23.976Hz video output? Why are so many hardware manufacturers having problems with this?

Incidently, the frequency of this happenning is every 3-5 minutes on my set-up ..... which is terribly irritating to me.

While 4K video support is impressive, Intel hasn’t completely fixed the 24fps issue that some people noticed in Sandy Bridge. By not quite getting the frame rate of video playback for this format of video, movies can appear to stutter.

When asked about this, Dr Hong Jiang, senior principal engineer and chief media architect for Intel, said that ‘we’ve improved the clock for Ivy Bridge, so that issue is much reduced. Compared to Sandy Bridge, it’s a major step forward.’ Tom Piazza, Intel senior fellow, chipped in, adding that ‘it’s significantly reduced – you’d have to look real hard to catch it.’

Intel must be f*^g NUTS to think that their attitude can be condoned. My WDTV Live Hub does not have this issue - glitches / flickers. I would hate to sit and watch movies with this thing happenning on my premium system.

So what kinda further tweaking on mpc-hc or VLC ..... will try out XBMC too ?

I am planning on Nvidia 660 Ti or just the 660 GPU (Asus) by Diwali ...... would this solve the problem ?

Meanwhile, I do not intend giving up at all ..... thanks to all you guys on TE for giving me the leads and everything else. Will keep updating as I run through various tests ..... I have over 1200 of the Best Movies that were ever made ..... and this silly problem needs a "solution"

EDIT: reading up on a very interesting test tight now Intels Ivybridge an HTPC perspective (the test bed matches my own rig somewhat )..... just quoting 2 things

One of the most talked about issues with the Intel GPU for HTPC purposes is the lack of proper 23.976 Hz display refresh rate support. Does this get solved in Ivy Bridge? In this review, we present our experience with Ivy Bridge as a HTPC platform using a Core i7-3770K (with Intel HD Graphics 4000)

and does RAM too have a role

As readers will see in a later section, it is possible that the memory bandwidth and latency can play a very important role in the video post processing performance.

curious ....

BACK AGAIN ..... SOLUTION FOUND to the various issues that came up on this thread

I just got my GPU - Asus GTX 660 Ti Direct CUII - TOP Edition
Nvidia Driver 306.97

My Dell Monitor is connected to the above - DisplayPort
My 47" LGTV is connected to the above - HDMI
Settings: 1920 x 1080 @ 60 Hz

1] Problem Resolved - Dell Monitor Blanking issue (or BSOD's as stated on other forums) - this used to happen earlier whenever we switched on our TV (with the PC also being ON) & when connected to the Gigabyte Z77 motherboard

2] Problem Resolved - Rolling Glitches on LG TV every 2-3 minutes.

3] Audio Output to TV : Media Player Classic Home Cinema 64-bit v1.6.4.6052 (32687bc) -> Options > Output > Audio Renderer > LG TV1 (NVIDIA High Definition (00200000)
Note: Using the above Media Player - there is no audio output on my PC Speakers BUT only for the TV - which is fine by me. As for any other viewing purpose on the Dell alone we use VLC or any other media player for sound on the PC Speakers.

CONCLUSIONS:
Problem no 1 & 2 is indeed a very serious issue with Intel & Ivybridge procs & the HD4000 too. The drivers or the Z77 boards do not offer any tangible solution.

I am extremely satisfied with the Asus GTX 660 Ti and Nvidia Driver 306.97 having resolved this issue extremely well - I do feel the Video output on my LG TV much crisper & no issues whatsoever at 1920 x 1080. Maybe it is the Nvidia Adaptive Vsync on the 660Ti which is amazing (I am not really qualified to hold this as a final conclusion to resolving these issues). However, I am really feeling very happy ...... [just that the final cost of my RIG really zoomed beyond the stratosphere lol]

I have had this card for 2 days only & yet many more things to check & finetune .... gaming

FYI - Tagging 6pack; @Vasishta.Sushant; cranky; ALPHA17; sid_donnydarko; and to spr (for pointing out a very important link Intel/Ivybridge problem with 23.976 ) - thanks to all.

Thread (temporarily) closed ..... Will confirm after a few days [system under observation].

I personally never had issues with any of my LG and Samsung HDTVs, with the Intel 4000. But I am glad that the problem got solved.

BTW I am also using the 600Ti. Wonderful card it is.

Your response contradicts my experience & could prove to be confusing to all of us.

Just curious (and confused) ..... Did you check & find things 100 percent perfect (Audio/Video output) from the motherboard with Intel 4000 onto your LG/Samsung HDTV's ! You never faced any issues of - dropped frames/video glitches on your HDTV's or your PC Monitor blanking on/off whenever your HDTV was switched on ?
- What proc / motherboard do you have ?
- What were your video output settings & what connection did you use?
- What were your "source" video files specs ?

It is important that you share your views, so that some clarity emerges about all the related problems as I have experienced (and what many other's) too about Ivybridge/Sandybridge playback issues with 23.976 - check these
AnandTech.com - Intel's Ivy Bridge: An HTPC Perspective - see page 5 comments
True or False: The Intel iGPU "Struggles at HD Playback"
23.976 Hz video output issue still not fixed in Ivy Bridge? - AnandTech Forums - quoted by @spr earlier & an extremely important link
and there are also score's of user feedback on newegg regards - Z77/68 & Ivy/Sandybridge having these issues - PC monitor blanking (or BSOD's) and video glitches on HDTV's.

Honestly I never saw any issue and it was never bothersome. Had this 3770k with Asus P8Z77 V Pro. Tried with both LG Scarlet 2 LH70YR and Samsung EH5000, using simple HDMI cable. Used KMPlayer with coreavc codec and played all types of HD formats.

Only recently I upgraded to 660Ti. For quit some time I was on HD4000, first on LG and then on Samsung.

The problem with HD 4000 was that it did not have high video memory compared to the 2GB of the 660 Ti, 1080p requires large video memory even if you are playing videos that too on a 47 inch one.

 

[Vasishta.Sushant]

It won't take more memory to play on a 47 incher than a 22 incher, as long as both are 1080p. Also iirc the HD4000 shares memory from the RAM and even 512MB is good enough to play HD videos.

I take you word.

Hmmm ..... this means that you are among those "extremely rare" blokes who has not encountered the various issues of Ivybridge 3770K/HD4000/HDMI & 23.976 playback on HDTV's.

Intel would be proud to state your case (joking). :happy14:

Hovever cheers to the 660Ti as it solved the issue for me and thanks for your inputs.

UPDATE:

INTEL (FINALLY) RESOLVES THE 23.976 fps refresh rate with Haswell
Tested with Intel Core i7-4765T - 2.00 GHz (Turbo to 3.0 GHz)
Intel HD Graphics HD4600 - Up to 1200 MHz

....
Talking of display refresh rate support, Intel has finally fixed the 23.976 Hz bug which has been plaguing Intel-based HTPCs since 2008. This is going to make HTPC enthusiasts really happy. The fact that Intel manages the best match for the required refresh rate compared to AMD and NVIDIA cards is just icing on the cake. The 4K H.264 decode and output support from Haswell seems very promising for the 4K ecosystem. It also strengthens H.264's relevance for some time to come in the 4K arena.

The Haswell platform ticks all the checkboxes for the mainstream HTPC user. It fixes some nagging bugs left behind in Ivy Bridge. Setting up MPC-HC with LAV Filters was a walk in the park. With good and stable support for DXVA2 APIs in the drivers, even softwares like XBMC can take advantage of the GPU's capabilities. Essential video processing steps such as chroma upsampling, cadence detection and deinterlacing work beautifully. For advanced users, the GPU is capable of supporting madVR for most usage scenarios even with DDR3-1600 memory in the system.
