I'm more than happy to host any ideas, criticisms or concerns from people who have played games on an A850 here.
One of the neat things about Samsung panels is that we allow the end user (you!) to toggle options that will allow you to get the most out of your television.
Game Mode is certainly a help. Most televisions will have additional picture processing that, while it improves the picture, may create a slight delay. Some manufacturers don't even allow you to defeat their processing (thus delay) at all, or at least significantly enough to get what you're looking for. Samsung does. But then you have to weigh your final picture processing results with the absence of lag. I don't think it will be *that* significant. But truly, you're the final judge on that.
A few things I might suggest:
1. Definitely output to the highest resolution you can from the game console.
2. Try your games without the game mode first, and then enable it and keep playing. Judge for yourself weather or not the picture difference is significant, or the lag even exists in your configuration.
3. If you have an hour to kill, pack up your game station and take it to the store and see for yourself. Make sure you like what you see, and let the salespeople address that concern.
4. Calibrate your games. Certain games like Guitar Hero have a calibration mode to compensate for delays. I don't know about all of them, but it might be a useful option.
Anyway, I hope I put some perspective on that. We have designed our sets to work great with games by specifically enabling and disabling technology so you can tweak the set to your preferences. I don't know who else who has put such an emphasis on gaming into their sets.
That's my take. Let me know if you have any questions.
Thanks for considering a Samsung.
I have already paid for an 850 and it's set to be delivered tomorrow. I'm having serious second thoughts though. Reading around online has led me to believe that Samsung LCDs have pretty severe input lag for gaming. I've also read that putting the TV in "game mode" reduces this significantly but also ruins the picture. So I don't know what to do...I do a fair amount of gaming (PS3, 360, and Wii), and though I'm not into the serious competitive gaming and don't do much online gaming either, I still want a set that will not present any issues when playing games of any genre. So, any opinions here? Should I be concerned? Does game mode really make the picture look bad? Like I said, the TV is set to be delivered tomorrow, but if playing games is a problem, then I'll have to get a refund and continue searching for a quality LCD. Thanks.
