Official LG xxLD550 xxLD520 xxLD650 Owners Thread - Page 156

Here ya go:

I suggest entering one set in Expert 1 and the other in Expert 2. Then see which you prefer or works best for you. You can also buy the Avia DVD on Amazon I think for a calibration aid.

Have you tried Djams 47LD520 setting I posted? It isn't one of mone and not in the usual place with the other settings. It actually should be more accurate than csamos for your 47LD520 which Djams also has.

If you liked csamos, Djams was done at 75% starting saturation and is also higher contrast in the end. Anyway, since you have AVS HD709 working, try that in your Expert 2 to compare. Just nake sure you read the instruction PDF to do it correctly.

First. . . Greetings Henry! Hope all is well.

If the source is a DVD it will be 60fps. If it is Blu-ray, it may be 24fps. We had a long "discussion" in this thread about the "slow down" or "frame drop/stutter". Some of remember it very well.

Anyway, a Blu-ray player usually has it's own video settings as does a game system for playing DVD or Blu-ray. I'm thinking the issue you are having may be because the game system is trying to send a 1080p 60HZ signal to the TV. 1080p should only be at 24FPS. When this discussion came up earlier, an owner with an XBox 360 also complained of this issue and resolved it I think, by changing some settings in the XBox and TV. . . I think. And, yes, Real Cinema will not be available unless a 1080p 24fps signal is sent to the TV.

You can try using the Search Thread feature at the upper right of this page and and search for "thegam3". You can start at post #473 and search his name for posts. I also think you could try a different output resolution setting of the Xbox. . . such as 720p.

Well, Otto, I don't think this will be coherent.

Ok, try reading the post I made above yours. DVDs are NOT 24fps. . . Blu-ray discs are, usually. DVDs are 60FPS.

However, you can play a DVD in a Blu-ray player and the player can usually be set to various output resolutions . . . sometimes from 480i, 720p, 1080i, or 1080p (60fps). All other resolutions should be at 60fps except when a Blu-ray disc is played which will output at 1080i 24fps (IF the Blu-ray player is set to output that resolution). The "stutter" you see may be caused by the Blu-ray player, game system, cable box, or DVD player outputting a frame rate that is not in sync with the TV. Another instance is if a computer signal is fed to the TV through HDMI. It should be at 60 fps. However, the TV operates at 120HZ panel refresh. Panel refresh is not the same as the signal input frame rate. . . . but the two are related. And therein lies a possible cause of synchronization. To confuse maters more, a 60HZ refresh rate is actually something like 59.97HZ. Which is another possible area of mismatch.

At least two of the "keys" seems to be it can be remedied by going to 720p with some input devices/source and it seems if the source is either a game system,cable box, or HTPC feeding a 1080 signal then the stuttering may occur.

It will be interesting if Henry can verify if his LG Blu-ray player does it. I Don't think it will, but if it does it may have to do with a particular main board rev level. The reason I say that is because my 42LD550 exhibits no stutter with 4 different Blu-ray players even at 1080p 24fps. I do get something that looks like occasional frame drops with my HTPC, but no video "slow down- speedup" and I attribute the frame drop to my relative slow 3mbps (1.9mbps to 2.3mbps) DSL speed.

I still believe it has something to do also, at least with some LD sub models, with feeding a 1080p 60HZ signal to the TV. This was not really a standard HDTV signal format. It also seems to be linked with the fact we have 120HZ panels, so it may have to do with faulty implementation of panel refresh verses input signal frame rate. In other words, the panel refresh (120HZ) is not syncing quite right with the FRAME rate of either 24fps and with some 60fps sources. Remember. . . Panel Refresh is not the same thing as input signal Frame Rate. . . but they are related in that the TV must be able to somehow match the two for proper display. This is a legacy leftover form CRT days when frame rate essentially WAS the same as CRT SCAN RATE. Since fixed pixel displays no longer "scan" an image onto the screen. Instead, the input video is processed into a digital bit stream, loaded into a memory buffer , and subsequently delivered as a complete picture "frame" in real time. But what if the overhead between this processing is not fast enough to keep up with the incoming analog or digital video signal? Then the TV might fail to process one or more frames now and then, till it catches up. . . resulting in a "stutter" or lost frame image. Well. . . this is just my opinion based on my understanding of how digital TVs now operate vs how they USED to operate.
