    If anyone could please give me a hand with this. When connecting my xbox 360 to this tv model I find a slight tv lag from controller to my actions on screen. I have seen many people having this same problem but all have a resource to fix it and I cant seem to find a fix for this model anywhere. I have tried different Tv's, different xboxs on the tv as well as calling customer support. Customer support told me that because the tv was so new there wasnt much she could help me with....

    I have looked up service codes for but cant seem to find it, I have tried original cables as well as expensive HDMI cables. I have tried the Game Mode also turning off 120 hz from the menu. In the xbox dashboard I have tried changing the resolution all each one that was given and still the same problem.

    If anyone can please help me figure out why this is happening and how I can fix it I would greatly appreciate it.

    Any motion smoothing tech should be disabled and game mode usually does that on Philips so why your still seeing lag could be down to the set itself has a high response time.

    The Philips FAQ suggest turning off 120Hz and enabling PC mode, there isn't anything else you can do after that I think.

    Lastly maybe its you, some people seem highly sensitive to lag & others are not. In that case changing TV or displays on the 360 is your only option.

    Thank you for your response

    I have turned off the 120 hz and also been using the game mode, and I am positive its not just me. When I switch the Xbox to an older television there is no delay or lag at all. I could not seem to find a PC mode? If you could elaborate more on that.

    I know now it has to do with the true hd motion on the TV or something in that kind of setting but I just cant seem to get this to work.

    Took a look at the manual for the 3705D and cant see a PC mode listed despite Philips mentioning it in their own FAQ.

    PC mode disables post processing and is intended for connecting computers to the TV.

    According to the FAQ it is in Setup -> Mode Selection -> PC Mode. Also the Xbox 360 should be plugged into HDMI port 1.

    If you dont have PC mode then try contacting Philips and see what they say, cant see any firmware updates for the set either though it is capable of receiving them.

    Just forget about playing games on this TV. I've made my peace with this. Its too expensive to send back to Dell -You lose 15%, tax, shipping (and if there was a promo on free shipping you may be on the hook for that too), so I'm keeping it.

    I spent a while on the phone with a very nice support person, but in short there is no solution. I have lag with HDMI. 120Hz off and game mode does not fix the problem. They were not overly confident, but they recommended I try other input sources and I've tried the horrible composite (no luck) and tomorrow I will try component input.

    Ready to hate this TV even more? There is ALWAYS overscan even in "normal" mode. Its about 5%. I understand the need for this to prevent artifacts in 120Hz anti-judder mode, but please give us an option. What this means is we can NEVER in ANY configuration get the full 1:1 1080p of this TV. Its beyond absurd. They need to add unscaled, unprocessed format ASAP or this TV will get trashed in every review.

    That said I have to say that the anti-judder is great in most videos with minimal side-efects and it looks OK after a long an painful calibration process. So for a TV to watch movies on its good, but forget about games on this TV

    Hi after a few hours of tweaking I figured out how to make this TV perform with video games!!! I was ready to sell this and gave it one last shot so here it is. When plugged to your PC go into nvidia control panel or catalyst control center and disable the sound output for the HDMI under resolution for nvidia not sure about ati though select HDMI (dissable sound) now set auto picture to game in the tv setup menu and voila there is slightly imput lag but barely noticable anymore instead of getting 5 kills and 30 deaths in COD BLK OPS i got 30 kills and 6 death and been killing more than dying again LOL so I believe it is working quite nicely now. This tv is amazing for blu ray and stuff just enable sound output for HDMI and enable 120HZ and you can watch blu rays at 120HZ and repeat again for gamming. when HDMI sound output is disabled 120HZ option is unavailable indicating you are in pc mode. This tv is great for gaming just a little of a nuisance to switch back and forth if you use your PC as a HTPC or gaming rig with blu ray of course. Hopefully they will patch this in a future firmware update and if you did not know yet there is a firware update on the philips site now for this model nothing I use was updated but at least they finally got new firmware out. not sure about the xbox if it has an option for HDMI sound enable disable you will know you are there if the 120HZ option is unavailable (grayed out with -- for it's status. Quite frankly i would recomend this for PC gaming and for blu rays on pc since it's simply better quality than a stand alone blu ray player which not many people are aware of but if you do your reaserch you will be informed about benefits of PC blu rays vs a player!!! I had this Tv for about 4 monts never gamed on it since I have an alienware notbook but outdated and wanted to play COD black ops with AAX16 on my tri SLI rig so I got right on it to find the fix since i did not want to invest in another tv as I would have gotten a 480 HZ RCA if I had too because I am all about specs and the philips had advertised 120HZ 2ms response time so I figured it was a really good TV and it is just a little hassle, I do have an xbox 360 somewhere and sorry I cannot tell you if you can disable HDMI sound output but if you can you will love this tv once again :laugh: I hope this helps some of you's. so you don't have to waste a few hours of farting around in the menu like I did, I would suppose for xbox you would need the analog and digital optical adio dongle for sound output as most people would use a surround anyways.
