Stuttering display on TV when connected to PC

[Zeus07]

Good morning

i'm hoping one of you guys have had this problem is able to help me with a solution for it.

I have a Hisense LEDN40D36P TV that has very choppy playback when connected to a PC. With other devices it doesn't do that at all. It's not the PC itself, it works fine when connected to an LCD monitor @ the same 1920x1080.
I assume this might be either because of the TV's attempts to smooth video, or a TV refresh rate & PC framerate mismatch, though I assume the latter would create screen tearing and not the constant stutter of games/movies that I experience. I've looked in the nvidia control panel and am searching for some settings that might help the PC output a display that might solve this issue, but so far no luck.

I see no settings in the TV's menu that relates to smoothing etc, so I don't think I can do anything on that side to fix the problem.

Any advice would be greatly appreciated.

Have a look what Windows has set the refresh rate to. Connect the PC to the TV, then find refresh rate in the Windows display settings. It might also be visible in the Nvidia control panel but I recommend using the Windows setting rather.

If it is set to 50Hz, set it to 59 or 60Hz.

have you tried the following..?

- different hdmi ports on the tv..
- different hdmi ports on the graphics card if available?
- onboard hdmi port with graphics card removed from the pc, if available?
- different graphics card if available?
- different tv if available?

dont think your graphics card is buggered, but it may not play nice with the hdmi ports on that tv..

I have a sort of similar problem when outputting Kodi to my tv vs to my computer. Either it's dropping frames or messing with the playback speed.

The only way for me to fix it is by first exiting anything else that's running, then it's fine. I don't get the problem when running on my main display.

Yes, it does strange things helping motion pictures in interlaced mode. Look for "PC mode" in settings.
On the PC side set graphic resolution to native mode of TV (1920X1080).

HDMI might not be certified or is an old HDMI version.
