I got this 3dtv for $50 but I didn't get any of the 3d stuff.
I am wondering if it's possible to do 1080p120 on this TV.
I can't get into the 3d settings because the transmitter is not connected, since I don't have it.

Re: Sony KDL-40NX711
Don't use 3D settings, but instead follow the instructions at True 120Hz From PC to TV, a method for tricking 120Hz modes on old 3DTVs that used frame-sequential shutter glasses.hyperlogos wrote: ↑09 Mar 2024, 12:43I got this 3dtv for $50 but I didn't get any of the 3d stuff.

Re: Sony KDL-40NX711
I'm on Linux, and I didn't see how I could apply too much of that to my situation.
I've tried creating some custom modelines, but the nvidia driver doesn't seem to make use of them. I am using a recent (hopefully latest) binary driver.
These are the modes which are announced by my display, from xrandr --verbose:

I found it interesting that there's two slightly different 1080p modes.

Re: Sony KDL-40NX711
I did figure out how to get the TV to accept my 1080p120 modeline, not sure if I constructed it right though.
In the /etc/X11/xorg.conf,
In the Monitor section:
ModeLine "1080p120" 297.00 1920 2008 2052 2200 1080 1084 1089 1125
In the Screen section:
Option "ModeValidation" "DFP-3: AllowNonEdidModes, AllowNon60HzDFPModes, NoMaxPClkCheck, NoEdidMaxPclkCheck, NoHorizSyncCheck, NoVertRefreshCheck, NoEdidDFPMaxSizeCheck, NoPredefinedModes"
It's DFP-3 here anyway, I got it from the Xorg.0.log file.

Re: Sony KDL-40NX711
Great! You've effectively done a Linux modeline equivalent of the old FAQ.
Does TestUFO properly show 120Hz nowadays in your web browser? Old Linux distros weren't very high-refresh-rate friendy.

Re: Sony KDL-40NX711
Unfortunately, when I tell it to do 1080p120 I get input out of range.
I guess one of the 1080p modes is 59.96 maybe, but they both show up as 60Hz (just with a (1) and a (2)) in nvidia settings.

Re: Sony KDL-40NX711
I also found another way to easily switch to/from 120Hz on Linux:
$ xrandr --output HDMI-1 --mode 1920x1080 --rate 120
$ xrandr --output HDMI-1 --mode 1920x1080 --rate 60
This probably requires at least some of the mode validation options above.
Still get out of range though.
$ xrandr --output HDMI-1 --mode 1920x1080 --rate 120
$ xrandr --output HDMI-1 --mode 1920x1080 --rate 60
This probably requires at least some of the mode validation options above.

Re: Sony KDL-40NX711
Try 720p 120Hz instead.
Some old 3D 1080p 60Hz TVs only support 720p 120Hz.
Make sure you recycle the broadcast standard ATSC 720p HDTV modeline, except with refresh rate multipled exactly by two. It's twice the dot clock.

Re: Sony KDL-40NX711
Not interested if I can't get 1080p120. This is already not very many dots for a 40" when I am sitting at it. I'll just keep saving my pennies for a 4k that does at at least 1080p120 if not 4k120.
