LG 38GL950G Refresh rate limit question

richintheveins

Sooooo running into an issue and I'm down to my last possible bit of hope. I just bought the 38 in Ultra Gear gaming monitor to replace my CRG9 that was running a little to slow for my taste. The LG is fast and responsive; however, its at a cost due to the limited bandwidth that display port 1.4 allows. To be able to keep 10 bit and full RGB in my Nvidia settings I have to run it at 120 hz. 

 

Has anyone ever used a Fiber Optic DP cable. They say their transfer rate is 32.8 gbs which is what I need to up my panel to its native 144hz. I just don't know if its all a gimmick or marketing nonsense. 

 

Thanks in advance.

Damn that’s a nice panel.

 

how come 1.4 won’t work? It supports 4K at 120hz, so why won’t it drive 3840x1600 at 144? What’s it capped at?

I use a LG 3840 X 1200 75hz monitor. I run it at 10 bit 75hz. 

Running at 10 bit 120hz would not be a deal breaker for me since all the games I have that benefit from 10 bit run between 70 and 100fps with my 2080 ti.

Next gen(3080 ti) may average 120 frames but not all frames so it will probably take another generation(4080 ti) to get all frames over 120.

 

Unlike my 75hz version this is a future proofing monitor even at 10bit 120hz.

No it’s not capped I can drive it at 8 bit 144 and 160 hz. 
 

I can also drive it at 175 hz @ 10 bit but with chroma sampling 4 2 2 instead of RGB. 
 

basically you have to give something up. The best the monitor can do without losing rgb or 10 bit is 120 hz.

Yeah I gotcha but my system was previously running on a CRG9 which is 5120 * 1440p and in some games on max settings I was getting well over 120 fps. I had to put v sync on which caused a lot of motion blur.

 

My current system is running a i9 9900ks, 32 gb of 4000 mhz of HyperX predator ram, and an Asus 2080 TI OC’d. 

 

I was really hoping to have it run @ 10 bit, full rgb, and 144 hz. I’ll settle for 144 or 160 hz 8 bit, full rgb. After testing I didn’t notice any difference between 8 bit or 10 bit in games.

Right now I am playing RDR 2 and averaging 72fps.  Before that it was Control that I had to drop the resolution to 3440 X 1440 to get a 60fps average with RTX on.  Before that Metro Exodus was in the 60s with RTX on at 3840 X 1600.  My setup with an i7 8086k at 5.1ghz and a FTW3 Ultra that can game at 2100mhz feels more like a potato than anything else.

 

For easy to run games I play at 4k with my other 2080 ti setup, so no relief for me.

Thanks in advance. 

A different cable isn't going to change anything. Fiber optic DP cables will run at the same rate as copper ones.

 

32.4 Gbit/s is the raw bit rate, which is what your copper cables are already running at. The data rate (after line code overhead) is 25.92 Gbit/s. Doesn't matter if it's copper or fiber.
