Intel UHD 750 Graphics Problems

SanjS3 · May 25, 2021

Hello, I just built my first PC and I have a few problems that I hope you guys can help me solve, the build is currently running on integrated graphics, and soon, when hopefully I get a GPU, I will put it in. The build is based around an i5-11600k with a Gigabyte Z590 Aorus Elite AX Motherboard, in a P500A case. I will soon add a 3060ti or 3070 into the mix when I can get my hands on one. https://pcpartpicker.com/list/sRw9z7 This is my full list of parts. I will have my problems listed below, it will be very much appreciated if you could just give me any information on what you think could help solve these.

First off, when I first booted up my PC, the bios was flickering on the screen. I setup the PC, got into windows, it was still flickering, then I changed my 144hz refresh rate down to 120hz and it worked fine, but when I go into BiOS it still flickers, and when I come out of BiOS into windows, the BiOS page looks burned into the back of my monitor which eventually goes away some how. (144hz is my monitor's rated refresh rate. My monitor is a LG-27GN850-B) I'm not sure why this is, and I have the Gigabyte Recommended Display Driver installed. When I switched my input to my Xbox on the monitor, the issue persisted, but then it went away on that input soon as well.
I also have weird missing pixels that show up, or sometimes there will be dots in particular places that are white or red, or sometimes random lines on buttons in chrome. I think this is down to the Display Driver for the Intel UHD 750 Graphics. I figured this out because to see if I could fix this problem, I uninstalled the driver, and suddenly, the missing pixels went away, so I contacted intel support, and since I had a more up to date driver than what was listed on the Gigabyte Website, they asked me to roll it back to the version listed on the intel website, but it still didn't work. Does anyone know why this is, or do you have this problem, or do you know how to fix it?
Do you guys have any recommendations to change settings on the BiOS, I have XMP enabled, and I turned on Multi Core enhancement, but that's pretty much it, I have a Cooler Master ML360R AIO in a Phanteks P500A with 4 MasterFan MF140r's on top of the AIO, and at idle temperatures, the CPU is around 19 - 25 degrees celsius, so any OC settings or changes that you may know of would help a lot.
I have put a screenshot of a QR code below, and the QR code is distorted and it isn't able to be read by a QR Code reader, if I uninstall the display driver, the QR code is fixed, and I can scan it properly.

Once again, Thank You So Much for helping me out, even just a few tips, that aren't related to my build would be very helpful! If I find any other problems, I'll edit this post.
