OK, I've been reading page after page of this thread over Remote Desktop and it's such a chore I just had to go ahead and ask my questions...
First of all, I made a huge mess getting this unboxed, so I decided to test my new KD-46XBR3 with the easiest thing to connect and try: my HTPC over VGA (XP Media Center Edition 2005 + 7800GS). After it warmed up, it looked amazing! I had to take it from Vivid to Standard mode to keep from being blinded.
Then I tried DVI-to-HDMI using a Philips dongle-style converter that converts the end of a DVI cable to an HDMI connector. I have the other type (Philips also) which converts it to a HDMI port at the card's DVI port, but I had no HDMI cable so I felt glad that I had the forsight to get both types when I found them on clearance. I selected 1080p and, strangely, there is significant overscan chopping off my taskbar, Start button, left column of desktop icons, etc. Why is this present with the HDMI input and not the VGA input? Are difficulties with PC input on other inputs the reason why they call the VGA input "PC input" instead of VGA? I thought I was digitally addressing pixels so shouldn't there be zero overscan?
I connected my laptop's ATI X1400 DVI port to the same cable and set my drivers to use the TV exclusively (primary display with the Laptop's panel disabled) and had a MUCH worse problem! The overscan is still present, but the icons on my dektop that I can see shimmer as if interlaced and all the text and borders have interfering lines as if the contrast was cranked up way too high on a CRT TV. Even without all the artifacts, the text is not crisp and straight. How can DVI/HDMI be that much worse than VGA?! I swaer, my VGA output looked digital, and all it ever takes is a glance for be to determine when a LCD is scaling VGA or using native resolution DVI so this speaks volumes about the opposite difference I'm seeing now.
Could it be that the cable is not a dual-link DVI cable? I thought that resolutions requiring dual-link cables simply didn't work with standard cables.
Could it be that the DVI-HDMI adapter, which has no "length" at all (being a dongle that fits on the end of the DVI cable), is not an HDMI 1.3 adapter? I mean, the resolution works, but the image is crap. If VGA looks good, even non-v1.3 HDMI should look better than this blurry artifacted mess.
My horrible results with PC connections on my Sony KV-30XBR910 (PC connection is "unsupported") are part of the reason I bought this set. If I can't get decent digital HDMI output from a PC, I don't want it. In fact, I was going to get a Vista Premium media center with CableCARD support so I wasn't even worried about the TV lacking this feature. Vista will require that DVI/HDMI for content that requires HDCP.
Other than the desktop, I had nothing to view in 1080p on the PC so I left Half-Life 2 installing and decided to see what 1080p looks like on some other non-VGA input. I'm too poor to get everything right away... I like to shop around. This meant that I have no HDMI cable for my Playstation 3. No worries, the PS3 can do 1080p over component, right? I dug up my official Sony PS2 component cables and held power for 5-10 seconds to reset the video to 480i. I selected the supported resolutions and the XMB (PS3 Cross Menu Bar dashboard/interface) defaulted to 1080p for the test. SCRAMBLED IMAGE.
It timed out and I set it to 1080i instead, but why can't my PS3 do 1080p over component?
The cables are PS2 component cables. Before purchasing them, I verified through Sony that they would work. After all, they look kinda wimpy for a 1080p set. Even before checking with them, I saw nothing in the manuals even mentioning a part number for the proper cables. It acted like there would be only one kind of cable period and did nothing to explain any potential differences or problems. So I guess my question is, would component cables not intended for 1080p cause a scrambled image or just a low-quality image? I always assumed the latter. Not rolling white lines pitched diagonally on a blank screen.
Am I going to run into any issues with an XBOX360 using 1080p over component? I've started collecting deals on all the XBOX 360 accessories but I'm still torn between getting one now or when HDMI-equipped models hit the market (mark my words: they will, and they will soon).
Also, I heard that many high-end Sony LCD TVs have video "blanking issues" with the Nintendo Wii (or perhaps certain titles for it). My friends played a good bit of Wii Play on the set last night and didn't notice anything, but does anyone know if the KD-46XBR3 is one of the affected sets?
