144Hz Montior stuck at 60Hz and system only showing it as a 60Hz

Pebor · 2022-01-05 17:54:16

Hello!
I just bought a new montior (ACER XV240YPbmiiprx) and it's 144Hz, but, xrandr doesn't report on it as being a 144Hz monitor.

HDMI-0 connected 1920x1080+0+0 (normal left inverted right x axis y axis) 527mm x 296mm
1920x1080     60.00*+  59.94    50.00    23.98
3840x2160     59.94    29.97    23.98
1680x1050     59.95
1440x900      59.89
1280x1024     75.02    60.02
1280x960      60.00
1280x800      59.81
1280x720      60.00    59.94    50.00
1152x864      75.00
1024x768      75.03    70.07    60.00
800x600       75.00    72.19    60.32    56.25
720x576       50.00
720x480       59.94
640x480       75.00    72.81    59.94    59.93

i've tried using `cvt` to make a 144Hz mode but it fails when applied:

1920x1080_144.00 (0x1f9) 452.500MHz -HSync +VSync
h: width  1920 start 2088 end 2296 total 2672 skew    0 clock 169.35KHz
v: height 1080 start 1083 end 1088 total 1177           clock 143.88Hz

~  xrandr --addmode HDMI-0 1920x1080_144.00
X Error of failed request:  BadMatch (invalid parameter attributes)
Major opcode of failed request:  140 (RANDR)
Minor opcode of failed request:  18 (RRAddOutputMode)
Serial number of failed request:  35
Current serial number in output stream:  36

My gpu a GTX 750Ti

Have I've gotten hardware stuck? What could be the problem?
I never thought 144Hz could be an issue.
Any help would be appreciated.

Which brand/model GPU do you have? It may be that it's HDMI output doesn't support refresh rates that high. Can you try using a displayport or DVI-D connection instead?

Pebor · 2022-01-05 18:16:15

as said in the post, my gpu is a nvidia GTX 750Ti
It should support all of this

Slithery · 2022-01-05 18:19:42

I know it's a GTX 750Ti, I asked for the brand and model.
Different manufacturers put different spec HDMI ports in them, some of which don't support that resolution and refresh rate.

That's an entry level 7 year old card. HDMI @ 144hz requires a comparatively recent version of HDMI, it's very possible you don't support this.

Pebor · 2022-01-05 18:28:02

Oh sorry
It's an Asus one.. haven't find a way to see the exact model, but there seem to be only two
GTX750TI-OC-2GD5
GTX750TI-FML-OC-2GD5
Most probably have the first one as its the one selling in my countries shops (at least what I see online)

That would suck, but, am also planning on getting a new one by the end of this year so.. if that's the case, might not be that bad. It just takes away my option to get my money back on the monitor if it's some linux wacky thing

V1del · 2022-01-05 18:35:07

Also often relevant which cable are you using and have you tried a different cable?

Slithery · 2022-01-05 18:40:36

It's not a 'wacky Linux thing'. Even on Windows the maximum output on a HDMI 1.4 port is 1080p @ 120Hz.
Try using a DVI-D connection instead.

Pebor · 2022-01-05 18:41:53

I just tried the included one, nothing changed sadly
But that was a good call

"wacky linux thing" only if it turns out not to be a problem with the gpu
Sadly I cannot test DVI-D because the monitor doesn't have that port
only HDMI and DisplayPort, which the gpu doesn't have

A DVI-D to HDMI adapter may be your only option, but it isn't guaranteed to work..

Okay! I'll at least try that.. am also gonna try plugging it into some of my friends better graphics cards running linux to see if it actually actually works as intended
Thank you so much!

Dual-link DVI isn't going to support that either.

You can try

% cvt12 1920 1080 144 -b
# 1920x1080 @ 144.000 Hz Reduced Blank (CVT) field rate 144.000 Hz; hsync: 166.608 kHz; pclk: 333.22 MHz
Modeline "1920x1080_144.00_rb2"  333.22  1920 1928 1960 2000  1080 1143 1151 1157 +hsync -vsync

but I'd not hold my breath… you're edging on the physical limit of 340MHz and even iffff you get a signal, it's likely unstable af. (but I expect the driver to filter the resolution)

Pebor · 2022-01-05 20:27:15

Of course that didn't work.. am just gonna have to wait for a new card I suppose ?♂️
I've seen people saying that they do 144Hz 750Ti no problem, so idk, I just wanted smoother scrolling and minecraft.

seth · 2022-01-05 20:33:05

The GPU can produce that signal but the outputs on your card are insufficient.

The monitor itself may not support a high enough version of HDMI honestly (I know mine doesn't which is why I use a Type-C to DisplayPort cable).

OP - you're going to have a read up a bit on what reso/freq combos work on specific ports. This is not linux specific, your cable just can't carry 'enough' signal.

Slithery · 2022-01-05 22:49:21

Which version of that monitor do you have? Is the part number UM.QX0EE.P01 or UM.QX0AA.P01?

I have the UM.QX0EE.P01 version

HDMI should be working fine with 144 on this, plus it can be "overclocked" (I know it¨s not the term) to 165Hz when using display port.

progandy · 2022-01-05 23:51:58

The limit is the graphics card with HDMI1.4.
I know of no DVI-D source to HDMI/DP monitor adapters, so that port is useless to you.

You could also try some 120Hz, e.g.

Modeline "1920x1080_120" 274.56 1920 1928 1960 2000 1080 1130 1138 1144 +HSync -VSync

https://tomverbeure.github.io/video_timings_calculator
https://www.epanorama.net/faq/vga2rgb/calc.html
or play around with some vblank and hblank changes for 144Hz, e.g.

Modeline "1920x1080"   324.576   1920 1928 1960 2000   1080 1113 1121 1127  +hsync -vsync

Really? I've seen hundreds of them. They're just a simple physical adapter as the video signal used by both is identical but dual-port DVI-D has more bandwidth so should be able do to 1080p@144.

DVI-I (single link) to HDMI is ubiquitous. HDMI is single-link, so you'd need an active converter that recodes dual-link dvi-d to single-link hdmi. I think there are a few converters from HDMI to dual-link dvi, but not the other direction.

seth · 2022-01-06 09:11:18

The mean part is that you can buy a lot of adapters w/ the physical dual link layout but of course the second data link pins are just decoration…

For the records, HDIM 1.3/1.4 provides 8.16 Gbit/s and Dual link DVI 7.92 Gbit/s but oc. has less overhead and no audio.
