i5/i7 1135g7 (most popular) - Intel Iris Xe Graphics don't support 144hz

johntawm · ‎02-18-2023

Problem

I have i5 1135g7 and same for i7 version, doesn't support 2560 x 1440 @ 144Hz

These are most popular CPUs on the market and I have HDMI 2.0, which does support this resolution theoretically, however, the driver doesn't seem to support it.

Additional Details

Currently using Lenovo Laptop, T14 Gen2, I have looked through many forums and there is no way to set this resolution, it doesn't support it, which is weird because this is one of the most popular intel chips and display combo on the market.

The display that I'm using is Samsung CHG70 27inch.

I tried installing monitor drivers, graphics drivers, Intel auto driver, reinstalling, using CRU software to set custom resolution, troubleshooting on the internet (tried a few possible solutions), none worked.

This is really disappointing that these issues are not addressed and most users won't be able to raise them or think about them because why would you as a professional spend time on this type of things, it's really important for me that the technology I buy works together and just having this monitor and not work as intended is a huge red flag.

What do you think? It's the same for 120hz or any other higher resolution other than 60hz..

Hey there, finally someone addressed this issue . i am also facing this issue . I am also not able to use my monitor at 120hz from my intel iris xe and i5-1135G7 . The last refresh rate i can change in settings is 60hz interlaced. Infact the lower cpu like i3 are able to run 120hz at 1080 . There is no monitor issue and cable issue

If you also have a Lenovo ThinkPad T14 Gen 2 and a Samsung CHG70 monitor, please connect the devices with an USB-C/Thunderbolt > DisplayPort cable.

2560 x 1440 @ 144 Hz RGB 10 bpc = 24.3 Gbps
This is not possible via HDMI 2.0 but only via the DisplayPort 1.4a HBR3 protocol. The Thunderbolt port can offer this.

No bro , I have Dell Insipirion 3501 with monitor ViewSonic VX2779-HD-PRO(180Hz)

I know it's hard to understand, but the capabilities of an HDMI port are not dominated by the graphics card but by the other technology that an Original Equipment Manufacturer (OEM) like Dell uses on the way from the processor to the port.

Since this laptop has no other video output, you will have to live with this limitation or return the device (if that is still possible).
