How do I describe this? Well lets start with known facts. The HD source is a DirecTV HD H21 receiver. Input connection, HDMI to DVI Converter. During the setup of the DirecTV receiver, it tests to see if the TV supports all resolutions, 480i,p 720p etc... It's telling me that it only supports 480p and 1080i, even though the TV will display the other resolutions, or at least it did. Well anyway, to the problem at hand. When tuned to a HD channel, and the resolution on the receiver set to 1080i, the picture becomes somewhat skewed and blurry as if the convergence is messed up. At this point the auto convergence will not run. It starts then it quits. I can adjust manually, but there is no change in the picture. Auto convergence will run just fine under lower resolutions, but not while in 1080i. But when I switch back to 480p (on the same channel) the picture becomes just fine. Any ideas?
As a side note. When using my old HD receiver an RCA DirecTV unit, I would have similar problem. But it self corrected in an odd way. Let me explain... When the picture was skewed as mentioned above, I would enter the receivers menu, then I would exit the menu right away, the screen would go black for a couple seconds as if the receiver was resetting or something, and come back on just fine in 1080i. It would only do that when the picture was messed up. Other wise entering and exiting the menus worked just fine. But with this new DirecTV receiver, the goofy picture stays. There is obviously something wrong in that TV. I can't blame the receivers. This is a goofy one. What do ya think?

Re: Picture goes goofy in 1080i
If that's a dlp unit they are garbage ive had two and both died in same manner in less than a year one the bulb blew on in three months after purchase then went blank and started making a high pitched squealing sound had to argue with rca cust support after repair shop said they could not fix it rca finally sent me a new one but with less features after i argued with them for another three that one did the same thing after three months now rca wont even talk to me and ive got a 100lbs paperweight that does nothing i was told it was the light engine at a cost of around a grand for part so don't waste your money on a repair shop mine is still sitting there blank and i understand this is a common problem from checking the web just roll it in the back yard spend you money on one that will work im going lcd this time and i do houseld appliances not tvs so dont worry about rating me i like to pass this info on every chance i get just to help my friends at rca

Your TV will display all High Definition signals as 1080i True HDTV™ and all standard definition signals will be displayed as 480p.
Component Inputs 1-2
These inputs can be used for the connection of A/V equipment with component video outputs, such as a DVD player or external HDTV receiver. Please see Appendix B for signal compatibility.
Input DTV (480i/480p/1080i)
This input is used to connect an external DTV receiver, and can be configured for YPrPb and RGB plus H&V signal types.
As a special feature, you have the ability to adjust the red and blue light beams in reference to the fixed green light beam. This process is called convergence. There are two separate memories for convergence. One, for SD 480i/480p signals; the other for HD 1080i signals. SD convergence should be adjusted while watching an SD source and HD convergence should be adjusted while watching an HD source.
Wide Expand: Enlarges the picture, cropping some of the image on both sides. This Expand format is useful to remove or reduce black side bars on HD broadcasts of 4:3 images with black bars. Available for analog 1080i, digital SD 16:9 and digital HD signals.
This input is compatible with most standard DTV and satellite receivers with component video (YPbPr) outputs. Compatible DTV signals are SDTV 480i/480p, and HDTV 1080i. All other DTV signals, such as 720p, need to be converted by the DTV receiver to one of the compatible signal types. Please check the DTV receiver specifications before connecting.
This input is compatible with some DTV receivers using RGB with "separate H and V sync". Compatible DTV signals are SDTV 480i, 480p, and HDTV 1080i. All other DTV signals, such as 720p, need to be converted by the DTV receiver to one of the compatible signal types. Industry standards for DTV RGB signals (systems, synchronization, timing, and signal strengths) are not currently established. These inputs will not be compatible with all DTV receivers that offer RGB, HV outputs. RGB, HV signals with less than 5 cables are not compatible.
If your DTV receiver offers both DTV component video signals and DTV RGB, HV signals, we suggest you use the DTV component video signals. Check the DTV receiver specifications before connecting.
Have you tried a different input like a DVD to ensure the issue is with the TV?
If the issue is indeed the TV then replacement of the video card (Or digital board) is warranted. If there is a separate board with all of the video inputs on it that would be the video board. If the main board in the unit has the video connectors on it, that is the digital board.
If you're using an HDMI cable your display will automatically adjust the settings based upon the video source. Make sure that your source is capable of outputting 1080p. If it's an HD Cable Box or DVR, the maximum resolution it can display is 1080i. If you have one of these HD boxes, set it to only display 1080i as there will be a delay every time you change channels from a channel that is not naturally at 1080i.
If your source is a standard DVD player, it can only display images in 480i (or 480p if it is Progressive Scan) and therefore your TV will display the picture in 480 resolution. If your source is an upconverting DVD player it will display up to 1080p however, Keep in mind that DVD's are in 480 resolution and that regardless of upconversion (or upscaling, though improved, the picture will not be in HD.
The only way to achieve a true 1080p (not dpi... that's dots per inch... that's a printer term. The "p" is for Progressive Scan as opposed to an "i" for Interlaced) is from a 1080p source, i.e., a Blu-Ray disc player playing a Blu-Ray Disc with the use of an HDMI cable. Component Cables can achieve 720p/1080i only with your TV as it does not support 1080p over component cables.
As an aside, there are some media players that support 1080p output and some DirecTV Boxes and DVR's d oas well for 1080p Pay Per View movies.
I gave up on the Cinema 7 remote control. I got it to turn the HD Receiver on and off by programing the L buttons but could not change channels. Although the Sony remote is very large, I programed it to operate the Receiver.
The Scientific Atlanta box was a cable box and recieved CATV signals. The Direct TV box is satellite only. You might check if it has a built in ATSC tuner for off air digital signals. Direct TV in most locations offers the major networks in HD format.
First thing to look at would be the source, make sure that this source whatever it may be is set to display a 16X9 format. Your set may simply be showing what it see's and it may be seeing the 4X5 format and giving you a problem
