Uhd750 doesn't work on my monitor

hi

 

The refresh rate of 1920 * 1080 120P can be seen in the display information support mode, but it cannot be selected in the display refresh rate. At the same time, uhd750 is not suitable for my current display. It can only reach the refresh rate of 60p in the state of 1280 * 720. My monitor is Acer ed242qr-a

1. It can support 1920 * 1080 120Hz under 8400 and 10400 CPU, the same motherboard, HDMI line and display

2. 1920 * 1080 60Hz on Xiaomi 4x TV (TV only supports 60Hz). In the same brand Acer 27 inch game model, it can 1920 * 1080, 120 and 144 in the same motherboard, HDMI and display state, but I can't use it at present

3. The current monitor has tried that Xbox s can run 1920 * 1080 60Hz. I've also tried other hosts that can run 144hz

4. Since the 11th generation CPU has been sold to the present, i been instrall all versions of the core display driver, which can not solve the problem

 

I hope you can help me solve this problem as soon as possible, thank you

 

 

 

 

 

 

 

你好

1920*1080 120P的刷新率在显示信息支持模式下可以看到,但在显示刷新率中却无法选择。同时,uhd750不适合我目前的显示器。在1280*720的状态下,它只能达到60p的刷新率。我的显示器是宏碁 ed242qr-a

1.它可以支持1920* 1080 120Hz下的8400和10400 CPU,同主板,HDMI线和显示器

2. 1920 * 1080 60Hz在小米4x电视上(电视仅支持60Hz)。在同一品牌宏碁27英寸游戏机型中,它可以1920*1080、120和144在同一主板、HDMI和显示状态下使用,但我目前无法使用它

3.当前显示器已尝试Xbox s可以运行1920 * 1080 60Hz。我还尝试过其他可以运行144hz 4的主机。自从第11代CPU一直卖到现在,所有版本的核心显示驱动都被打乱了,这并不能解决问题

 

 

希望您能尽快帮我解决这个问题,谢谢

What do you mean when you said "It can support 1920 * 1080 120Hz under 8400 and 10400 CPU, the same motherboard, HDMI line and display"...

The motherboard model in the report MSI B560M BOMBER doesn't support 8th CPUs so no way you can test the same motherboard with an 8th and 11th gen CPU...

 

And when you say "In the same brand Acer 27 inch game model, it can 1920 * 1080, 120 and 144 in the same motherboard, HDMI and display state, but I can't use it at present"... do you mean other display could reach 120 and 144Hz with the UHD 750?

 

First thing you need to do is to test with different cables... it "doesn't matter" if they work with other displays/computers... it is very common that cables may come with bad quality and present issues with some displays computers... you may find many evidence about this in this and other forums... myself included...

hi
Thank u to reply my post
I mean when I use b360m with 8400,it can reach 120hz. The same hdmi cable(cable 1)/monitor.and I use b560m with 10400.also can reach 120hz same hdmi cable(cable 1)/monitor. So I think my monitor isn’t the problem

And I’ve tried Xbox s original hdmi cable(cable 2). Also can’t reach 120hz. So i think hdmi cable is also not a problem. more like hard drive issues

And I test other monitor like 27 inch acer can reach 120hz at b560 with 11500 with my hdmi cable (cable 1) .

Thanks again

HI 

 

LOL,my problem may have been solved

 

After I confirmed that there was no problem with my monitor, because it could be read in Intel's official SSU that the display could correctly identify 1920 * 1080p 120Hz, I began to read how to overclock on the network. After I downloaded the custom resolution utility and overclocked the display to 144hz, I could set the 120Hz refresh rate in the display settings

 

so I'm pretty sure the problem is with the driver

 

thanks again

hi alx24

 

u mean my hdmi cable is hdmi 1.4. but hdmi 1.4 aslo can use 1920*1080p 120hz

 

and i overfrequency the monitor temporary solve the problem,but I wonder why I can't use it directly without overfrequency

 

thaks again

It can be noted that the characteristics of the Intel Graphics emphasize the maximum resolution and quantity
monitors, increasing Bits per Pixel (BPP) 24 to 36 not maximum frequencies. Not so long ago, there was a transition to 4K and 8K in TV. "Max TMDS Clock Rate: MHz" very often accompanies problematic displays. The frequency of 120 Hz can be reached in the Dual-Link DVI (special cable) that is in your display that is quite a significant plus in relation to the high frequency over the HDMI channel.

 

Windows:

Settings -> Display -> Blue Link "Advanced Display Settings" -> Blue Link "Display Adapter Properties for Display N" -> Button "List All Modes".

Sheets "Adapter", "Monitor".

 

Always simplest test by reloading in "Safe Mode" which uses Microsoft Corp. "Microsoft Basic Display Adapter". ( 64 Hz )

 

There is Display Driver for this Display on display manufacturer site.

 

It is very likely that 1280x720 at 60 Hz is taken in EDID from "Standard Display Modes" and "Detailed Timing Descriptor" is not accepted.

"Monitors"

There is no compatible tested gaming displays HD, 5K.

There is a possibility that this latest driver has not been tested at high V frequencies.

 

"Same motherboard" means that the performances of 2 channel memory are sufficient.

 

There is "Intel Graphics Control Center" (IGCC) "Display".

"B560M BOMBER" has only HDMI video digital output.

Xbox uses AMD Graphics.

 

In the display EDID there is standard resolution 1920x1080 at 60 Hz but it's not even accepted.

(148500000 / (1920.0 + 280)) / (1080 + 45) 60.000000000000

For 120Hz "Pixel Clock: 286MHz" ("Bit-Depth" = "8-bit"). If "HDR" is enabled, then in Windows 11 Intel Core 11th Generation Processor Xe Graphics "Bit-Depth" = "10-bit" and "Pixel Clock" exceeds 297 MHz, which is the limit of Intel Corp. for HDMI 1.4 and this graphic mode will not be set and displayed.

It is worth noting that the resolution of 1920x1080 at 120 Hz has the same video data rate through the interface as at 4K resolution (3840 x 2160 at 30 Hz), which is very easily implemented in processors starting with Intel Core 4th Generation and with Intel HD Graphics 4xx. Such performances had even a very old interface Dual-Link DVI.

 

The next stage of a very significant increase in graphics performances falls on Intel Core 11th Generation Processors.

You may publish here SSU data of display "Acer 27 inch" for compare.
