Thank you for starting this thread and answering questions about this new TV.
In the Bravia 2010 thread, I had posted some specific questions in post #1426 on page 48.
Link should go here... but AVSforum won't allow the link because I don't have 3 posts yet.
Oh well, here's an updated summary of the questions.
I'm really looking forward to getting the HX800 40" when it is available. You've actually already answered a question I didn't mention. I'm happy to hear the "glossy" screen is not as bad as the Samsungs. Hopefully the reflections will not be too bad for my setup.
1. The main question I had which should be easy to answer is if "AUTODIMMING" can be completely disabled.
2. The other question concerned hooking up the HX800 to a computer to see how the output looks. (1 to 1 pixel mapping/no autodimming/lag on the mouse). I realize that is potentially difficult but if you happen to get a chance, it would be nice to know how the TV performs as a large computer monitor. But I only really want to know this info with a digital connection (i.e. DVI out of computer -> HDMI in to TV ... OR ... HDMI out of computer to HDMI into to TV. I know analog VGA to the TV Input VGA is not good quality.
3. This question about watching 3D on the TV through a computer will mostly be answered when Nvidia finally releases the 3DTV Play software which will interface with a graphics card and enable some kind of HDMI 1.4 conversion?? It sounds like it may be a good solution. Lots of PC computer games will then be instantly available to play in 3D. The question is how well nvidia's 3DTV Play really works? So I guess this question will have to wait.
If you do happen to hook the TV up to a computer with an DVI to HDMI cable, try to see if you can select 120hz for the HX800 instead of the standard 60hz. Sony Engineers claimed this would be possible. I'm very skeptical of this, but if true, the TV would act like a really nice flicker free computer screen. Also, if true, nvision would work which would be another avenue for 3D...
4. You've already answered the question of input lag. If the lag is good enough for your girlfriend to ace Guitar Hero, its probably good enough to drive a mouse when using it as a computer monitor. I know I've tried other TVs a computer monitors and the lag was bad enough that the on-screen mouse trailed my movements by about 1-2 seconds. It was unusable. Hopefully the HX800 will be fine for this.
5. New question. Can 3D content be viewed while using "game mode"? I assume this must be yes because Sony is going to sell lots of Playstation 3D games!
Sorry I have so many questions. If you could even just answer the first question, it would be a big help because AUTODIMMING is painful and doesn't work at all when using it as a monitor... I've been waiting for so long to get a TV which acts like a computer monitor and I think this may be the one.
Thanks again. I hope you also get a chance to enjoy the thing!
