Anyone else having this problem?

I just got the Mitsu WD65734 TV and wanted to get started on COD4

So I set the Xbox to "1080p" and started playing. After a few seconds the screen started to flicker (or flash)...not really skipping, but more of a, well, flicker. After several of these instances, the screen went black, then came back on and flickered some more. I went back to the control panel of the xbox and put it back to 1080i and started playing again...no issues.

I have the xbox connected via HDMI cable (through my Onkyo 605 receiver). As far as I can tell there's hardly any difference between the 1080i and 1080p picture....but you know...the TV has 1080p capabilities...I want to play the xbox in 1080p!!!

any ideas what this could be due to?????

Let me know if I've managed to leave anything out....thanks!

Try hooking directly to the TV. Bypass the receiver. This will determine which is at fault.

Try a different brand HDMI cable. I've seen that before. It was cured by switching to a different, equally inexpensive HDMI cable.

P.J.

i would bet that it's handshake issues with the AVR. do what Kil said.

Well for one thing, your TV can only display a 1080p image...no matter what you send it, its going to display at 1080p. So if you dont get the flicker, send the signal at 1080i...you're still seeing 1080p, you're not losing any quality.....but you may get a little lag.

Then set the output to 720p and see how the TV scales it up to 1080p, that might also be a good route (remember almost no xbox games run about 720p natively anyhow).

Sounds more like your TV isn't receiving enough of a signal strength and its dropping the signal and then resynching.

this makes the most sense.

thanks all

"send the signal at 1080i...you're still seeing 1080p, you're not losing any quality.....but you may get a little lag."

As has been explained many times here, that is only true for sub-30 fps or sub 540p material.

Do yourself a favor, velozi, do not accept 1080i as being good enough.

1080i is not 540p. There is no such thing as 540p.

1080i is not 540p. There is no such thing as 540p. And if THAT has been explained here many times well... Wow.

He didn't say 1080i was 540p he said you lose frames in anything above 540p or running above 30fps if you convert it to 1080i. I suck at explaining how it works so I'll leave it to james or Shape if they feel like explaining it yet again but you should read a post properly before responding to it.

"1080i is not 540p. There is no such thing as 540p."

Do you also believe that there is no such thing as 240p? :) I figure if we're living in a fairytale land where certain resolutions just can't exist because sage11x says so, then we might as well get rid of that one too!

You might want to step on over to the HTPC section of this very forum and tell all those guys that the 540p that they ran on their HD CRTs for all those many years just wasn't possible.

As an added bonus, I didn't say that 1080i is 540p. What I said is that you can't cram more than 540 lines worth of information into a 1080i interlaced field that only has 540 lines when you are trying to deal with a refresh of higher than 30hz.

Hate to tell you this chief, but I run a 1080i set and I can see games running at 60fps.

And before you jamokes jump all over me about 1080i specifications and 60fields versus 30frames per second and whatnot....

You take a 1080i set....play a game locked at 30fps, play a game that runs at 60fps....there is a noticible difference in the crispness and response of that game on the 1080i set.

Ok... didn't think my two sentences were going to create this much controversy or hijack this thread.

I will agree that 1080i basically limits you to 30 FRAMES per second but your assertion that the OP will only see 540 lines of resolution detail is just wrong.
1080i has 1,080 lines of detail that is broken up in to two halves or FIELDS and displayed at 60 FIELDS per second. 60 FIELDS per second = 30 FRAMES per second as it takes two fields to display a full FRAME. The full image FRAME is 1,080 lines of detail- doesn't matter if it's broken into two FIELDS of 540.
The two FIELDS creating the single FRAME create an image that is very detailed- 1,080 lines of resolution detailed. But because the image is essentially the two HALVES (your 540 lines) being displayed in quick succession displays that are INTERLACED, like old CRT HDs, can exhibit artifacts during fast motion.

HOWEVER, the OPs display is NOT an interlaced display, it is a PROGRESSIVE display. As HeadRusch put it earlier the OPs display will DE-INTERLACE the signal- displaying the two FIELDS together as a single 1080[P] image FRAME at 30 FRAMES per second. Some displays will still show this as 60fps but really you're seeing the two fields displayed together twice...

In the end this is all a moot point because as HeadRusch pointed out earlier *most* 360 games are rendered at a resolution of 720p or lower and then thru hardware are scaled to meet the resolution of the display. This is not PC land where changing the display resolution changes the render resolution. While the OPs display will show 1,080 lines of resolution you will not see any more detail out of an image that is 720 lines.


Back to the OP and the original issue, I'll agree with a few posters here that it sounds like an HDMI issue. Does your display accept 1080p thru component? If so you could try using the component cables to isolate the HDMI. I used this trick to isolate an issue with my HDMI connection from my HDDVD player to my 768p display. :p
