Ok, Agent 477, my answer is less than simple: Wait, don't buy anything for about a year, and here are some of the reasons why I advise this. First off, it should be obvious that the television manufacturers don't like having to adjust for all of these silly formats. ie 48i,480P,720i,720P,etc.. They must do it, therefore they have a lag problem adjusting for it. Furthermore, they also don't like having to adjust, still more towards the input side, for the "scaling" of the picture sizes and differences in 4:3,16:9 ratios and the fact that even within the 16:9 ratio, the movie 16:9 and the television 16:9 are different. Ask the front projector guys that sell screens to explain all the silly formats. This causes more of that lovable bit to analogs and analogs to bit BS that we have been buying into for so long. Makes you feel smart buying digital junk until you try to use it, then you have to apologize for getting outsmarted supporting companies with your development dollars. See cell phones that don't work, and the fools that own five of them to prove it. Make the marketeers pay for the marketing.
There was a PBS/BBC series called "The Fall and Rise of Reginald Perrin" and in one of the episodes a silly British buffoon news anchor, with a chin like a boat anchor, needles Reggie about how it cannot possibly make sense that he has been so successful with his chain stores that sells broken and useless junk. He goes on to say surely he should feel guilty or dumb luck guilt, etc. Reggie's reply was something like, "Actually, we would rather have it break at the store so the customer will buy two of them". This was true in the late seventies and is triplely true today. I just bought a Motorola modem and it was junk, so I wasted 1.5 hours of my time doing QC for them. I bought my first XBox and it failed within thirty days and they repaired it with a used, noisy drive, and an out of balance DV-reader, and they stole all 50 CD's of music I had on the hard drive. The first DVD writers everybody had to have in their computers and laptops were near worthless, and pretty much it still is a worthless medium for data storage. Vinyl is the best and magnetic tape is the second best. Vinyl will still play words or music 50,000 years(actually longer) after we are dead, magnetic tape thousands of years, and CD's 7 years 4 months and 4 days, as long as they do not get wet or used at all. You see, we are schmucks.
OK, if you really have to have a big screen wait at least a few days and check out the 60" XRB2 rear projection Sonys that will be about as good as it gets for picture quality and response time 2.5mS(not refresh rates). The LCD's will not cut it, the plasmas go dead if you leave them off for more than 3 months, so the best of the lot will be a none DLP Sony LCOS based system. Source what Brillion TV's use? Now it has the 2.5 version of DCM, and noise reduction, and a whole bunch of other DA to AD stuff(I consider capacitors analog), and it will stretch and shrink and manipulate colors with the best of the bit clockers on the other side of the fence(DLP). All of this trash is pretty much as dumb as not using a video camera to record film, but animating instead within a two frame split(everything non-streaming data or just say microsoft). Well they had us buying that garbage for years and we raved about how fast it was, and to me it was like crapping a walnut with the shell still on (barely tolerable, yet slow, and not going anyplace else).
Seriously. Go to the super duper gizmo, speed by the speedbump, electronic stores and hook up your game box. Play Madden, Tiger Woods, and/or MVP Baseball, and you will likely find that it will not kick, swing, or hit(respectively)in the proper timing necessary to make you go home with a chub. Still scan for sexxy women on the way in and out of the store though. Anyway, there is nothing that will play better than this new 60" XBR2 RPTV, and nothing that will look sweeter for movies and HD OTA than this 1080P, except maybe a Fijitsu Plasma, or a Panny plasma or the new Panny front Projector or the Sony pearl front projector. And as is true in porn flicks and bank accounts, bigger is better. When you play any one of these games,as mentioned throughout this thread, it is the play of the swing/kick meter that will show you if the timing is on. Game mode 480P should work, or 720P if the game and feed supports it. Don't fool yourself. If this set won't do it none of the other TV's, (likely a front Projector Sony Pearl either, since it shares the same LCOS and 3 LCD concept) will do it either. It will sell at first for $3900.00, and then for about $3500.00 before XMas. If it won't fly, try the test again with all the picture massageing trash turned off, and let's hope you chubb out of the store this time.
Why would someone buy an HD TV to have the thing dim, lose contrast, and appear washed-out, when playing games?? We are Americans, so we do quality control for manufacturers for no pay. We ship their junk that they failed to burn-in and test at the factory back to them at our expense. We buy things like cell phones that don't work, and even buy them again and again and again. Someone in this thread, as wise as me, but with much more brevity and less levity said that you must realize you cannot have what you want, and move-on. If this simple, easy to assemble, and timely test works out for you, then you are home free. If not, wait at least another year before you beat yourself up. I will be doing the same test, and I am mad as hell that this has not been corrected for the 15 years these companies have been doing this, but it is what it is, and the government was more hinderance than help(like usual). GSM cell phones work very well overseas, and you do not need to give anybody your name so Uncle Swine can track your every move(except video gamer's thumbs>refresh rate faster than 1mS), or beg to sign a, worthless for you, contract to make a crappy phone call. Nope, only here would we call that a free market. Take econ 101 to realize that having monopolies is counter intuitive to quality and free market access.
Before everyone thinks I is dumb. I realize that refresh rates and Response times are different animals feeding at the same redundant trough. I also realize that scaling is more than just picture size. I also know that we are stuck with processing this stuff coming in on the front side, and that is less related to refresh rates than I made clear. What I will say is that if on the front side, and in the middle(color processing), and if at the end (2:3 dropdown or pulldown) or anywhere in-between you have to keep synchronizing, then you will have a hard time matching the near instantaneous digit-L and ocular response times. Be careful what you ask for. Oh, and I am not implying that any of you can watch streaming data smoothly on your computers(jeez I am not stupid). And I know the difference between analogue and anal-log. IMHO everything, shy of number crunching and simple run time data acquisition, that is digital, just plain sucks. Good Luck, and don't fool yourself or buy band-aids for $4000.00 products.
I have a 6 year old Sony 32" tube TV that has a beautiful picture and works well for a monitor/game. If you don't mind buying something that works for a change(joking). Also HDVHS is a lovely medium that has more longevity in its' recordings. Just for the sake of posterity.
