all games locked @ 24fps @ 1920*1080

[MonKENy]

But if I switch to 1176*664 It goes back to 60fps.

Im using a Panasonic TC-P50S60 50-Inch 1080p 600Hz Plasma HDTV
I had the PC hooked up to a Samsung UN65KS8500 Curved 65-Inch 4K Ultra HD

but Its been shut down and restarted, all the settings say 1920*1080 so its not still at a diff resolution. Even Nvidea CP says 1920*1080 native.

It used to run @ 60 before I hooked it up in the other TV.

Any ideas?

 

[MonKENy]

I dont know why but the TV seems to be locking @ 24hz.

I would try the following in order or in combination:

1. Delete all custom resolutions in NVIDIA CP
2. Ensure you are set to 1920x1080, 60Hz, 4:4:4 (RGB or YCbCr) and bit depth to whatever works best (8, 10, 12, etc.) Sometimes going to the Windows display dialog box advanced settings allows you to select resolutions not exposed by the NVIDIA driver (stupid but true)
3. Check to see if there's a "game mode" or "PC mode" in the TV menu
4. Try each HDMI input on the TV
5. Create new custom resolution in NVIDIA CP if necessary
6. Download CRU if NVIDIA CP fails

Bonus Point:
Are you passing the signal through an AVR (receiver)? Are the settings for that AVR and input/output configured properly?

 

[MonKENy]

If I switch to windowed (no border) it sets @ 60hz. Going back it reverts to 24hz. Grrr

Ill try deleting any custom resolutions but I just did a fresh clean install of the driver.

 

[nathanddrews]

Definitely recommend installing CRU. You can delete all other resolutions from the EDID and only allow 1080p60 to be used. Windows/games will have no choice but to use 1080p60.

 

[MonKENy]

nothing worked.

 

[nathanddrews]

nothing worked.

And you're certain this TV used to do 1080p60 and not 1080i60?

Try a different cable? VGA?

 

[MonKENy]

doesnt take VGA, yep positive it was 1080p60.

 

[psolord]

Make a 1920x1079@60Hz custom resolution and use that in games.

Weird I didn't have any trouble with Nvidia's driver with all 4 of my HDTVs. It's AMD that gave me some trouble in the past, but they are OK as well now.

 

[MonKENy]

Im not sure either but oh well. If I play border less it works fine.

Have you disabled the silly, fake refresh rate trickery? I note that you say "600Hz" TV, which means it has some of this awful frame interpolation tech to make stuff look smoother, which is usually tuned for 24p video content. In case you're wondering, no, the TV can in no way refresh at 600Hz. More than 60 would be a minor miracle.

If your TV has a HDMI input labeled 'DVI' or 'PC', use that.

And in general, remove any and all "image enhancements" and other processing in the TV menu. Those things can mess stuff up pretty good when connected to anything but a dumb STB.

Turn off vsync.

 

[Valantar]

Turn off vsync.

...that doesn't help much if the TV is refreshing at 24Hz, now does it?

 

[wildcard-x]

Its most likely a setting on the tv not matching the setting on the computer. I have Panasonic gt50 and it has an option to do 24fps. (it's used for movies)
The 600Hz is the sub-field drive not the refresh rate.

It is 600Hz because as he said, it's a 'Plasma' TV, not an LCD.

Sure thing. Now, please tell me which display interface in the known universe can transmit a 1080p600 signal. In other words: the display itself might theoretically be capable of refreshing that quickly, but there is no way to transmit an image to it at that rate. In other words: it's not a 600Hz display, and anything above 60 is interpolation.

I understand that, but for motion, nothing beats a Plasma. Ever watch a sports game on a Plasma vs. an LCD? No comparison.

I'm not arguing against that - plasma has per-pixel response times so short they're hardly worth mentioning, knocking the socks off even the fastest LCD. And faster response times will make motion look smoother at high enough frame rates (and most sports are broadcast at 60fps). But none of that means that the TV will be capable of neither refreshing the panel nor transmitting a new image to it at a rate faster than 60Hz - which is why TVs use junky, clarity-killing frame interpolation techniques to simulate the intermittent "frames".

So your Panasonic Plasma TV supports "24p Playback (3:2)/24p Smooth Film"

I wonder if this is causing it? According to some other threads i read, you can disable 24p playback in the Advanced Settings of the TV's menu.

When this is enabled it syncs the output device and the tv at 24fps. Can you disable this?

Seems pretty clear that this particular plasma is stuck in film mode (24Hz) and needs a setting changed before it will operate at 60Hz - like the OP says it used to.

I understand that, but for motion, nothing beats a Plasma. Ever watch a sports game on a Plasma vs. an LCD? No comparison.

As the owner of a Sony Pro PDP and ex-owner of a Pioneer Kuro among others, I'm not saying plasma is bad, but LCD never had a chance at beating plasma. Likewise, plasma didn't last long enough to beat CRT in motion or response time, so let's not pretend that plasma was the greatest ever. It was great, but had its share of compromises.

600Hz (480Hz, 840Hz, etc.) is marketing fluff. Every plasma uses a sub-field drive to render out a frame of video. Depending upon the brand or model, one frame is divided into 8, 10, or 14 of differing intervals in order to correctly display brightness and color for that frame. A brand using 10 sub-fields at 60Hz = "600Hz" on the marketing sticker. For film-based content (24Hz), most plasmas operate at 48Hz, 72Hz, and even 96Hz, so you can wind up with a variety of sub-field measures - all of which are not comparable to a native input refresh rate.

Spoiler: CRT at 10,000fps

Spoiler: LCD at 1,000 and 2,000fps

It wont let me disable it when playing a game. I noticed that as well. When I full screen it locks that setting to 24p when I window it changes to 60p.

Its frustrating but playing windowed borderless doesnt seem to be an issue so since this is a temp setup Im going to live with it.

Hey OP this seems more related to a known issue that I believe originates with Windows. A lot of suggestions I came across suggested disabling Windows Gaming DVR and it helped in most situations.

Currently playing Nier Automata, and launching the game, it's locked at 24 FPS. I have to toggle Windowed to Fullscreen to get above 24 FPS< and then I got to toggle back to Windowed to get G-Sync to work.

I have no idea what causes this, and it's only on specific games. I'm using a monitor and not an HDTV hook up. So for me I know it isn't a cinema mode, it's just weird coding - some where.

That sounds about in line from what ive been reading on other sites. Oh well it is what it is.

 

[skulkingghost]

Try a different HDMI port, some only support certain HZ

 

[MonKENy]

using the same one it used to work fine on, but i did try both for good measure.
