Custom Resolution Utility (CRU)

[vortex240]

Hey guys! I've looked around everywhere but I can't find an actual answer - maybe someone here knows. Is there a way to add a custom resolution on a neo G7. It has the same panel as the g8, so 240hz should work.

This is on nvidia, apparent amd cards have no issues with this. Cheers!

Hi , i have an Acer monitor V246HL @ 60hz , it has 1 DVI port and 1 VGA port. (this is my second monitor but i am intending to gift it)
It is connected to a RTX 2060 super GPU via DVI SL cable.

The DVI port on the monitor has the holes for Dual Link DVI but i coudnt find anywhere information about if the port is actual DL or not , i only have SL-DVI cable atm.
Some variation of this monitor model with the same specs have display port too and thats what makes me think maybe the DVI port could be DL.
Found a similar monitor that its rated at 75hz and it says that the DVI is dual link: https://www.displaydb.ro/monitor/acer-v246hl-bmdp
My model is v246hl bmd UM.FV6EE.005

I have some questions/ problems.
Does it worth getting a DL-DVI cable for it? (im OC-ing the monitor ofc)

I tried the patcher and it doesnt seem to make any difference, the max clock seems to be @ ~165.6Mhz, going any higher i am getting "Input is not supported".

I managed to OC it to 75HZ with this settings"
H: 32 32 32 96 2016
V: 3 4 4 11 1091

The problem is that i am getting a lot of tearing in games when i am using it at 75Hz but it seems that is working without tear at stock 60hz.

After playing a bit with the settings seems that i can get 75Hz with different timings, something like: ( i didnt try to see if tearing is gone yet with this settings)
H: 8 32 32 72 1992
V: 14 8 6 28 1108
(i started tweaking the values from CVT-RB2 standard and changed H Black porch from 40 to 32 and V Front Porch from 25 to 14 (i think it works with 16 too)

My question is what timing are better lowering/ tweaking so i can be @ max 165.6MHZ pixel clock and maybe to get rid of the tearing (if possible)?

Atm i am playing with V Front porch and H Back porch, should i lower V Front porch and leave the H Back porch higher or viceversa? It seems that is working doing it both ways with different values if i keep the pixel clock below 165.6Mhz

I am getting tearing at 75Hz with the old settings even if i cap the fps at a stable 75fps or if im uncapping the FPS, seems that capping the fps higher gives me less tearing but is still too much, only the Vsync seems to help which i do not like.

Edit: In the user manual i found this but the manual is like somehow general for all the variation of this model.
Anyway if it does indeed have dvi-DL could i get maybe a higher OC?

There's no reason for that monitor to have dual-link DVI. The patcher is for GPU driver limitations, not monitor limitations. Tearing has nothing to do with the monitor or the timing parameters. Use vsync if you don't want tearing.

someone understand what config must use in cru for 75hz for hp e190i.
as i read internet info, this is standard freq for this model. but i havnt 75hz in os

this is cru automatic pc setting:



this is original monitor setting:

That's a 60 Hz monitor.

Thanks for the reply , that is what i thought too but i had to be sure, i see no reason for DL on the monitor but in the manual says its DL (in the specs only says DVI-D) and I was wondering if indeed its DL if i could get an higher OC because of the higher bandwidth.
I was not sure about the tearing as i am not having tearing at 60hz but i am having it at 75hz and more noticeable if i cap the fps at 75fps, using like 72hz , 73hz without altering CRU timings has less tearing and thats why i was confused.

Edit: pic with the back of the board , seems that it has the pins for DVI-D DL soldered if i am not wrong:

So, I've this old Asus VH222 1080p 75Hz monitor, paired with a R9 380. As you can tell, this setup is ancient and the R9 380 is essentially a 1050Ti that consumes almost 3x more power.

Now the thing is, this setup is no longer able to hit solid 60, let alone 75. So, what I've done is underclocked my monitor to various refresh rates (40/45/48/50Hz) via CRU. When I can't hit 75, I just move down to 60 > 50 > 45 so on (48Hz is just for films).

The problem is that it's getting harder to maintain even solid 45FPS and when I set the refresh rate to 40Hz, the input lag just gets unbearable. It feels fine at 45Hz, BTW. My question is, is there a way to improve input latency?

Detailed resolutions have lots of parameters etc. so I was wondering if it's possible to somehow "tighten" the monitor's timings or something at 40Hz, just to make it more bearable? For example, high refresh rate monitors often suck at 60Hz because they introduce a lot of input lag and I feel like I'm facing a similar "phenomenon" at 40Hz on my 75Hz monitor.

Like for example, the Asus VG279QM has extremely high input lag at 60Hz, as per Rtings: https://www.rtings.com/monitor/reviews/a...#test_1435

So, is there a way to lower the input lag or am I all out of luck?

Thanks in advance.

Only certain high refresh rate monitors with FreeSync have lag at 60 Hz. Most monitors don't behave that way. Monitors that don't buffer frames usually have no significant lag at any refresh rate. You mentioned you prefer using vsync with the frame rate capped. That's where the lag is coming from. The only way to avoid that lag is to disable vsync and remove frame rate caps.

You shouldn't cap the frame rate to the refresh rate. That's the worst thing you can do for tearing because you'll get a jiggling line. Tearing looks bad when the frame rate is close to the refresh rate. You want the frame rate to be as high as possible away from the refresh rate. If that's not achievable, then at least cap it to something a few frames below the refresh rate. Capping the frame rate to 70 FPS at 75 Hz will look better because the tearing won't be in one spot. The only way to avoid tearing completely is to use vsync, but that will add lag.

Most 60 Hz monitors are hard-coded to reject anything beyond 75-85 Hz. Using a dual-link DVI cable won't change what refresh rates the monitor will accept. The monitor and GPU have no way of knowing if you're using a single-link or dual-link cable. The GPU always sends a single-link signal up to 165 MHz pixel clock and a dual-link signal beyond 165 MHz no matter what cable is being used. The patcher raises that to 230 MHz. If the monitor actually supports dual-link DVI, then you won't need the patcher beyond 165 MHz. If the monitor only supports single-link DVI and the GPU sends a dual-link signal, the monitor will ignore the other link and the resolution will have a blocky look with half the pixels missing unless you use the patcher to send a single-link signal. That 165 MHz switchover is exact by the way, so anything beyond that is a monitor limitation.

I see. I didn't realize that some monitors have frame buffers. BTW, is there a way to 'test' whether or not the monitor has a frame buffer? The thing is, I've been meaning to replace my entire setup and am thinking about getting at least a 144Hz FreeSync monitor so... just in case.

Googled turned up nothing and you're pretty much the go-to-guy when it comes to monitors so I apologize for asking so many questions!

Thanks in advance.
