用電腦睇高清電視個畫面會"震"的問題

小弟用N記GF9300或A記3450播高清翡翠台, 個畫面會有輕鬆的上下震動, 靜態的畫面尤其明顯
但改用N記GF8800GT時, 就沒有此情況
我曾經去過電器舖睇過某些HDTV都係有此情況, 但唔知佢地用邊款機頂盒做source
究竟係我setting問題嗎? 有冇巴打可以幫一下, THANKS

It is because you are using Bob as the method of deinterlacing. (deinterlace is a must for HDTV)
N記GF9300或A記3400 are too weak to use advanced deinterlacing method.........

There should be no solution.
For A記3400, you may try to set the deinterlace to adaptive or above if it is available in CCC.
If not, you may try to use DXVAChecker.

但我見GF9300用PureVideo3, 但GF8800GT只用PureVideo2
不是VP3比VP2好的嗎?

VP3是全硬解, VP2是半硬解, 這是對還是錯的?

這是對的, but there is no great difference between VP3 and VP2 except adding support to VC-1 DXVA.
The ability of post-processing is still depending on the card's power.

我見電器舖d HDTV駁機頂盒都有此情況, 即係個機頂盒粒chips質素唔夠好嗎?

我本來打算係駁LCDTV的, 但電視機未送到黎
而家駁DELL 22" MON, 行1680x1050, 我只可以選60Hz, 就算untick"隱藏此監視器無法顯示的模式", 都係得60Hz
駁LCDTV後set 50Hz就沒此問題了嗎?
Thanks

This is due to the wrong setting in refresh rate.
In my case, 8 STB + Sharp LCD TV, 60Hz results in 震 of pictures while 50Hz does not(as that of the signal is 25Hz).

This problem will not cause 震 in the case of computer.
This will cause lag of video(happens in both TV and PC actually) as 5 frames of 25 frames will be repeated per second when choosing 30Hz/60Hz for monitor.
