Custom Resolution Utility (CRU)

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?
