Bad picture when set to 1080p with hdmi

For the most part, the 360 renders to 720p. The question then becomes, "Which scaler is better looking?" between your two devices. Does the 360 take 720p and convert it better than your display?


We do know that the scalers in the 360 are quite good, but also pretty sharp. So, what you are describing may simply be the aliasing that will sometimes be apparent due to the nature of displaying a 720p source on a 1080p display. If your displays scaler is "softer" than the 360's, then that would explain the lack of fluctuating pixels on the 360's 720p output as the display would be softening the hard edges of aliased 720p, but probably also softening fine details as well.


The static? Well, there lies a problem. If you are describing actual static in the image, then something is broken. More than likely, it's just a bad cable in that case. A cable that almost works.

Check the specs; if the display accepts 1080p/60, try a different port.

(You're talking direct 360-to-tv connection, right?)

If its not the cable you have a hardware problem.

definitely an issue somewhere, i've seen hdmi "sparkles" like that with a defective cable, and later with a defective AVR (harman kardon).

Now that I can see a picture, I can tell you that something is broken. Overheating framebuffer RAM could cause that, as pixels would start getting corrupted before being output. In which case, bad 360. It could also be a bad input on the panel, if scalers are failing there. The cable run is of a reasonable length, like less than 12 feet, right?


You could narrow it down if you've got a second display (like a 1080p capable PC monitor) to hook up to.

Which model is the tv? Have you tried different cables? You said you checked the cables but does that mean just checked to make sure they were connected properly or changed entirely? As asked above do you have another moniter you can check the 360 on?


I've had some similar issues on my 720p Samsung plasma when using component (original 360) in 1080p (my tv accepts 1080p/24). I get a slight halo or soft ghosting around defined lines that goes away when I set it to 1080i. It even does it in 720p which is wierd. I need a new 360 lol.

Switch the cable. That looks like HDMI sparklies.

The 360 is brand new, my old one got the ring of death so i just bought one.


The TV is a Samsung pn58b54 plasma, brand new. Has three different HDMI ports, tried it on all of them with same result. It sucks because i dont have a

blu-ray or any other 1080p hardware to verify if its the xbox or tv. I could hook my PC up to but im concerned about breaking the tv before doing that.


This issue is only when set to 1080p, no issues with 1080i or 720p.


Im gonna go by another cable to see if thats the cause for sure.


Cables are only 6ft

If it isn't the cable take the 360 and switch out then the tv if it isn't the 360.

I've seen similar visual artifacts before RROD failure. In fact, that looks a lot like what my original 360 was throwing up shortly before it got really bad and pooted.
