[QUOTE="findftp, post: 952758, member: 115630"] Why not? My TV also have hardware deinterlacing onboard. I wouldn't be so sure. Like I said, nowadays TV are very capable of doing everything onboard, for free as well. One extra advantage is the offload of the GPU. I think it is just strange when you have a TV capable of doing 100Hz and let the 1080i25 input be doubled by mediaportal, and let the GPU to the deinterlacing and forward the 50Hz stream to TV where it again is doubled to 100Hz or even further to 200Hz. Best performance for PC would be in my opinion 25Hz (dumb) interlaced to TV and let that device decide the magic. Less GPU stress, beter picture (because TV algoritms receive virgin stream) Anyway. I put my desktop in 1080i25, and tried to get the TV client output 25Hz, but it ended up 50Hz each time. I don't really understand. I've been messing arround with the dynamic refresh rate settings, and I think either HDTV or TV is responsible for that. Probably also the reason that you cannot change their names (but CINEMA and PAL you can) So I took a DVD and let it output 25Hz but the deinterlacing went not that good, yet. I'm still experimenting with it. [/QUOTE]
