Right off the bat I made the same mistake I always make which is I forgot to reset to factory default before inputing my settings. Im really hoping the issues I am experiencing are simply a setting a missed.
My set up:
I have 2 displays:
Optoma H31 projector (480P) connected to component output 1
Early 2000s Sony 16:9 1080i CRT tv connect to HDMI out
I set up duplicates of all my video source inputs:
Video output config 1: Component priority, 480p, SD color space, YPbPr 4444
Config 2: HDMI priority, 1080i, HD colorspace, YCpBr
On both displays I am getting less then stellar video quality. The biggest thing is badly crushed whites in bright scenes (see picture). The green/purple stuff in the CRT pic was a camera artifact, I couldn't see that in person. Both displays appear to need minor brightness, contrast and color/tint adjustments after putting the d2 in the video chain, but much bigger changes than Ive seen when swapping out VPs in the past. The picture adjustment settings in the D2 (button 7) appear to all be at default. Any thoughts on what setting in the D2 could cause this?
The second problem is I am seeing some image distortion/ noise on both displays. On the projector (component) I was watching True Grit DVD that was included with the bluray, DVD player was outputting 480i, and I was seeing some odd gray horizontal banding across the screen in dark scenes that would kind of move up and down. This was visible in the letter box bars as well, but again only in darker scenes.
On the CRT (HDMI) I was seeing some static (as in not moving) narrow vertical lines that where either green or purple (see pics, in the picture they look gray but it gives you an idea what it looked like). In both cases the source was a Denon DVD2910 via component.
All this considered, I can't help but wonder if the video board is failing. Do these sound like a typical video board failure symptoms? The amount of video setting on this thing is amazing so Im really hoping its something on my end but I really need to determine wether the unit needs to be retuned or not. Before the d2 I was using a pio 1121k AVR and the picture I was getting from that was better across the board which leads me to believe something is wrong.
FW is 1.33
Any help would be greatly appreciated.
UPDATE: I watched some HD cable through the projector the other day and the picture seemed ok so its looking like the problem might be specific to the DVD player. Will test further...
I think a lot of the problem here could be due to sending RGB to the Component input of the D2 and having a mismatch in the Input Color Space setting (Video Source Adjust Menu > Picture > Input Color Space) for which flavor of RGB is being sent by the source. Again, this is related to the INPUT side of the D2, not its output.
In the D2, set that to Studio. If that doesn't fix it, go to the source device and look for a setting in it related to output "black levels" which offers only 2 choices. The choices could be named anything (there's no consensus on this), so just try both choices for the output of the source.
That's your best shot at fixing the white crush. (If this is the explanation your near blacks would also be wrong.)
For the horizontal interference patterns: If they are continuously scrolling slowly upwards then you have the classic symptom of a "ground loop". A ground loop is garbage current that travels between the devices in your setup along the cable shield of the cables connecting them -- trying to find a path to ground so current can flow. The devices don't even need to be turned on for this to happen. The most common interference is power line noise, and this scrolls slowly upwards because TV frames happen at a slightly slower rate than 60Hz.
There are lots of possible sources of ground loop garbage current, but these days the single most common is garbage coming in to your house on the shield of a cable or satellite TV feed. Again, even if you are not viewing that feed. To test this, simply disconnect that feed wire where it comes out of your wall and see if the problem goes away. If that fixes it then you need to properly ground that feed wire where it enters your house.
If that's not the cause, disconnect EVERYTHING from the D2 except for power and video input and video output and see if the problem goes away. If it does, start reconnecting things in logical order until you figure out how the garbage current is getting to the D2.
The vertical garbage on the HDMI output could also be related to a ground loop, although the symptom is not common.
Instead the problem may be in the "digitizing" of your Component video input to produce the HDMI video output. This could be due to a problem on the video board, or it could be you need to make some adjustments in the Video ADC settings (again, in Video Source Adjust > Picture). These control how the Analog Component video is digitized (ADC: Analog to Digital Converter).
When fiddling with the Video Source Adjust menu, keep in mind that there are a separate set of Video Source Adjust settings for each Source line. So you have to actually view each given Source line before you can view/change the Video Source Adjust settings for that line.
