2K resolution, but only with 30 FPS

[RM1985]

Yesterday I tried to run some games in 2K resolution (2560x1440) and they all look great, BUT somehow I only get 30fps in all games, also non-steam ones, even though they were running with 60fps before.
What could be the cause of this? My graphics card (GTX 1080 8GB), maybe my monitor (used my 4K TV)?
And I didn't even try the newest or demanding games, more like older games like Left 4 Dead 1+2 or GTA Vice City and San Andreas.
Anyone has ideas on how to fix this?

My TV is almost 5 years old, maybe this could be the problem, may have to check for settings for 60 Hz.
The cable could also be the problem, since it was rather cheap, but I still have two other, one from my receiver and one from my PS4.
But since my new monitor will arrive today, I don't have to worry about the TV anymore 😉

Definitely check the specifications for your TV's inputs.

When your TV is connected to your computer Windows can display the refresh rate it is using. Your graphics control panel may have refresh rate options.

Make sure you are connecting your TV to your GPU and not your motherboard, as motherboard outputs may not have the same specifications as your GPU. In addition, you may be locked to integrated graphics or have overhead due to having to transfer the video output from the GPU to the integrated graphics for display output.

This might help a lot to pinpoint your issue, please answer these questions.

What the display model having trouble?

What are you using HDMI, DVI, or Display port?

Did you check if the display cable not the issue?

Did you do a video driver update recently when the issue occur?

Ensure not using something that trying to press it own vsync, or messing with the game own vsync.

Did you mess with Nvidia control panel for handing vsync, or DSR?

Disconnect TV so system not seeing it, try rebooting after disconnect TV, and test out games with vsync was there any changes? Before doing this if you have lot of items on your desktop, take a screenshot so you can help yourself reorganize them for later.

1. I used my 4K TV
2. HDMI
3. How could the cable be the issue? It is intact, if that is what you're asking
4. Video driver updated yesterday
5. How should I know if something is messing with the v-sync? Where to look? Nvidia settings?
6. No, I only set the max framerate to 60 to disable v-sync and have a stable framerate!
7. So just pull the HDMI cable or what?

So if using Vsync only set things to 30FPS, then means either something wrong in TV settings, you have to check your TV manual on this to ensure not having issue running things at 60hz which shouldn't be an issue out of the box, but not sure what company will do something dumb, and gimp people on products for going cheap tvs. But less likely to be the case IMO.

If you're using a 3rd party software like rivatuner, or anything that limits game FPS, or to handle vysnc for you that might be the issue. Also if using geforce experience, ensure it not messing with game settings for you as in some cases it might do dumb things, and you have to check game settings for FPS limiter if it has a setting for that.

HDMI capble, you need to ensure what type it is, and in the past there few TV's that fight people to getting correct hz if not using HDMI 2.0 on their 4k TV by the manufacturer design, can't say for sure, as not sure which tv model you're using, and if there any known issues to it, or not.

Try using your 2k monitor you bought, see if you get 60FPS with vsync in game using same HDMI cable that you use with your TV. If you do, then likely the TV having a fit about the cable type, or just the TV itself.

It's ok, problem is solved, I got my new monitor, plugged it in and everything is fine. Problem was probably the HDMI cable, which wasn't a high speed one. Maybe my TV isn't set to 60 Hz. Doesn't matter anymore, but thanks for your tips anyway :104:

I recommend checking TV settings about, but also good to know you had cable that wasn't meeting the needed bandwidth to support 60hz.
