How to run multiple refresh rates on 2 displays

NadeMagnet69 · November 7, 2020

I have a 43inch Acer CG7 which has native 120hz with OC potential to 144 if you use 2 display port cables. When I had a 2080 FE I'm positive I was running at 120hz. But luckily I heard about the 3000 series in time to return the 2080, with lol all of 2 days to spare. So now I'm back with my old GTX 660 until I can manage to get a 3080. I didn't bother checking what hz I was running at when I tossed the 660 back in until today. Today I just added a small 5 inch screen as a sensor panel. Its max hz is only 60. Now my Acer is also stuck at 60. I can only either set it to 60 or 30hz. Can older GPU like the 660 run multiple refresh rates or am I doing something wrong? Never had multiple displays before so I'm a total newb. It's not that big a deal if I'm stuck at 60 for now, it's not like the 660 can run any modern games. But if it's not a GPU problem I need to learn how to fix this. Any help would be appreciated.

You are better off waiting until you get your new GPU before trying to correct this.

Well have you tried Nvidia panel? You can set different settings for different displays. You can find it if you right click your desktop

Yes lol of coarse. I might be a mulit panel newb but not a total newb.

The problem is this old vid card. First off it looks like it's not going to be able to run 4k at anything higher than 60hz. I can either drop the resolution and bump up the HZ, or 4k at 60. That took a few hours to figure out. Then I spent hours just trying to get my CG7 to be my main screen that win boots to first. This damn old vid card can only boot in order. Dvi then hdmi then dataport, and my CG7 is on dataport since I didn't have a spare HDMI cable. The 5 inch is HDMI. lol Do you know how much it sucks to try and look at BIOS shrunk down to a 5 inch screen? Finally figured out a work around by using my motherboards HDMI while keeping the CG7 on the 660. And then if that wasn't enough lol I've had to research how to shut down my NZXT hub so the 5 inch doesn't stay stuck on saying no signal. Still haven't found a work around for that. Setting windows to shut off USB in device manager won't work. I think it might be the cable since I'm using this one to one of the female ports on the hub. https://www.amazon.com/gp/product/B002M8RVKA/ref=ppx_yo_dt_b_asin_title_o01_s01?ie=UTF8&psc=1

I picked that cable because this 5 inch display came with a 180 degree micro USB to USB thingymabob and I wanted to rout the cable directly behind the screen. And that hub is only 10inches away. https://www.amazon.com/gp/product/B08343QX67/ref=ppx_yo_dt_b_asin_title_o01_s00?ie=UTF8&psc=1

I'm hoping a long enough to run to the back IO micro USB to USB cable will fix the problem since I know I can shut off those ports when the PC shuts down

Sigh... I just wanted a freaking sensor panel. 5 hours so far for something that should have taken 5 min. But a plus is the screen is actually decent quality and is IPS. I managed to get a custom resolution on it to 1920 x 1080. It's native is only 800 x 440. Of coarse at 1920 my sensor panel would be incredibly tiny, too tiny to be good for more a than a couple to a few simple gauges instead of the more complex one I already made. But it's nice to know I can at least get a good picture if I ever use it for something else. Besides 1920 though I couldn't get any higher resolutions to work after 800 x 600. lol Don't ask me why 1920 x 1080 worked. That's waaay higher than any of the people reviewing this screen said they got theirs.

Yep. It's the GPU. Which makes sense I guess. Back when it came out, 4k at higher than 60hz was probably still a dream. Did they even high refresh monitors then? If they did I bet they were super expensive.
