Friend's new screen capped at 144hz instead of 165hz.

[Euphytose]

Hey, my friend bought and just installed his new screen, the VG279QL1A.

Problem, it's capped at 144hz instead of 165hz.

He's using a DP cable, 1.2, and he tried overclocking the screen in the menu, but the image wasn't stable at all, so he went back to normal. The cable came with the screen in the box.

I'm using a very similar screen and all I had to do was let Windows download a driver, then swap the refresh rate in the screen's properties, nothing else.

I didn't have to navigate the screen's menu at all.

He's using 1080p res, updated driver, etc... No clue what's wrong here.

If you know where the problem is, would appreciate the help.

Thanks for reading and for your replies.

Enable FreeSync Premium, OC in the Menu, then go to Display Settings and see if that Refresh Rate appears in the Win Display settings panel drop-down, if so, I would then see what happens when turning off Screen OC in the OSD Menu but I am pretty sure this revolves around FreeSync Premium.

Thanks but the image was really bad and the screen was making weird noises with the OC, I don't think it's wise to try to OC again.

I'll tell him to try to fiddle with the freesync though.

Edit: He turned off adaptive sync, but nothing changed.

As for me, no "sync" of any type was enabled by default so it's a bit strange he had this.

Still, his maximum refresh rate is exactly 143.85hz for some reason.

Yes, then do the thing with FreeSync but don't forget to tell him about the Windows Display Advanced Settings drop-down menu - I say this because one time I helped someone who had refresh 240Hz and they had to ENABLE FreeSync PREMIUM in order to reach that rate (I'm not sure how it actually works because I don't have FSP nor this monitor).

Yeah in the menu it only goes up to 143.85hz unfortunately.

Edit: In the screen's menu there's no FreeSync premium, just "adaptive sync" and G-sync.

Edit 2: Forgot to tell you, he has a 4070 Super, not an AMD card, this may be why.

Tell him to turn on G-Sync then and maybe check on that Max Refresh Rate in the Nvidia App/Nvidia Control Panel or something.

If no solution works, people that own this monitor are reporting a fault with the monitor as new RMA monitors are arriving without issues pertaining to FPS limitations - Welcome to the Monitor Lottery.

G-Sync was already turned on by default on the monitor unfortunately.

One time, I had a monitor (still use it) that used drivers but one day those drivers failed but I used the MS Windows PnP drivers - my other monitors had two pairs of drivers (one signed and one unsigned) and it turned out that the unsigned drivers were more stable.

I can't remember but I will be doing this soon as well, Nvidia Control Panel had the settings for Refresh Rates also; however, I am not sure if this new Nvidia App has those anymore or any options pertaining refresh rates at all.

I'm looking at his screen's manual right now that I found on the Internet.

It states this:

"1920x1080@165Hz (Overclocking)"

So basically, 165hz is only reachable by overclocking, which is extremely annoying because like I said, the OC wasn't stable at all.

So yeah, gonna stick to 144hz basically, better to do that than to destroy his screen lol.

On the website he bought it from, the number 1 seller in our country, nothing indicated that an OC was necessary, this is really stupid.

Well that is just - all this fine print nowadays.

Return the Monitor. Buy one with 165-180 non OC

Which GPU is he using?

Cable needs to be DP 1.4

Gonna be too complicated unfortunately. He will stick with 144hz, already a huge increase from 60hz.

Edit: He's using an RTX 4070 Super.

But on the screen's page it states that 1.2 is enough since the screen outputs just that.

Like I said, for my own, I used the cable that came with the box and that was it, it worked perfectly.

144Hz seems good for 1080p.

Yeah, that is a 144Hz panel OCd to 165 which is both hardware and content dependent

Also, he will need to lower it as well with HDR if/when he enables that. IIRC that panel will do its full-depth HDR400 at 120Hz; which is what Bad Motha is essentially getting at regarding the DisplayPort cable. DP1.2 is all that display supports so depending upon the content you are trying to send to it, it will have a bandwidth limitation that he will need to choose what settings are more important to him.

[Euphytose]

The refresh rate is more important than picture "quality" to him so the current settings will probably suffice.

Thanks.
