    Which one do you choose ?
    I'm using Philips 7007 3D TV 40"

    Auto Select (Recommended)
    Desktop Programs
    Photos
    Movies
    Games
    Full Screen-Videos

    Do you see any different ? cause I can't see anything it does or change

    I have only desktop programs and video available but I leave it as auto. My TV is set to PC mode so I don't think this option makes any difference. Just make sure your output dynamic range is properly set (nvidia) and same with hdmi black levels in your TV. Those made the biggest difference in colors for me.

    Unless you need the audio through HDMI, use CRU 1.3 to disable the extension bits to have it be detected as a DVI connection. This helped with frame times, TV mode related latency and proper color spaces and black levels with my 47" LG 1080P TV.

    I need 3D .. can I disable all and keep 3D option ?

    Can you show me what you disable or such and what you have in the CRU option ? I use it already to delete the 59Hz because it drove me insane. now 60Hz works fine but I'm still looking how I can improve it more. but I don't know how or what while keeping the 3D option available.

    It still works for me. I've tried it with movies and games like Sniper Elite 2/3 and Diablo III.

    Can you show me screenshot what you disabled or how you do it ?

    I want to see it , do you have skype or anything so we can do it faster ?

    Because I still need it to be detected as HDMI so I can watch Bluray movies, if it doesn't detect as HDMI it won't detect the Real 3D or Sequential 3D , no ?

    Also I want to use DSR and such.

    I'm not sure what to do so it detects as DVI cable + 3D support + Bluray3D support + DSR and no audio.

    I only know how to make it work as HDMI with full 3D and full 60Hz without 59Hz.

    this is how it's now , it is using PC resolution and not TV or ULTRA HD thing. do you mean this mode or there is other mode which mean HDMI ? cause now it's HDMI-HDTV

    I might be able to help more at a later time tomorrow. It is 3 in the morning where I live and I'm heading to bed. It was really simple for me, quite surprising in fact. All I did was use CRU 1.3, export my HDMI bits just to be safe, delete them from the "Extension blocks" box and then use the "restart64.exe" provided by CRU. That is the ONLY thing I did and every single thing I've done since then has been exactly as intended or better than before.

    Pretty sure all you have to do is delete/use a blank extension block.

    Then I lose 3DTV and I can't play games using the 3DTV. only play 3D movies . so I guess I can do that cause I don't use it much and only for movies and can always import back.

    But I'm not sure why there is the Default Extension and the Hdmi-Audio and such.

    What exactly I need to choose, to delete all the the TV Resolution and use Default Extension , that's it ?

    but if I delete ALL of them then I will lose the Colorimetry and all the things they won't work after like 12bit and such. and maybe 3D at all

    I'll be damned...

    Just tried this on my Samsung 4k TV in PC mode over HDMI and its noticeably improved frametime in games. I wonder why the hell this isn't a native option in drivers or TVs at this point. It might be just my imagination but it seems to reduce input lag a tiny bit as well.

    Good to know I'm not one of those placebo driven whack jobs... at least in this case.

    Dang. Not quite sure what to tell you. My TV is passive 3D though, maybe that has something to do with it? You can try deleting each individual "bit" under the HDMI extension stuff as trial and error to see what does and doesn't work for your TV.

    Awesome! Glad you found this and that it helped. Just to be clear, I am *NOT* the first person to discover this or mention it. I just spread it like wildfire now to help as many people as possible using TV's for gaming rigs. It was a 4 year (on and off) quest to get my TV working perfectly as a gaming rig and only through Guru3D was I able to do it.

    No placebo here for sure, my frame times leveled out perfectly compared to horrible stutters in every game/engine with standard HDMI. I just helped one of my best friends build a 6600k/RX480 machine and he hooked it all up to his TV after I left. He bought a Vive, set it all up and asked me why it stuttered and skipped so much. I went back over, did this CRU extension bit thing and PROVED to him, via MSIAB graphs, that his frame times were terrible before and perfectly stable now. He also shouted out "Holy crap!" after loading up a VR game post fix.

    Yeah, its rare finding tweaks that aren't complete snake oil this day and age. I usually try anything I find either way just to be sure but this definently works and is certainly something worth passing along. Thanks for sharing Builder, cheers.

    This is just a compatibility setting for programs that do not treat a selected color space properly set within the control panel.

    Desktop Programs is geared towards the RGB color space and Full-Screen Videos towards the YCbCr color space. If the graphics driver isnt properly switching to the correct colorspace automatically for content running on your computer (depends on if the software is coded properly to tell the graphics driver to switch), you can force the type of content through this setting.

    Could someone please make a screenshot of how it looks? (The old img/link is deleted) Whenever I try and delete all extension blocks for my Tv's resolution the image gets scewed somehow. I have a lot of lag in my TV and this would be really helpful.
