Iris Xe Graphics 2560x1080 resolution support

[nutlaf]

Hello everyone. I need help with something. My computer model is Lenovo Thinkpad e14 gen4. The processor is Intel i5 1235u and the graphics card is Intel iris xe graphics. I want to buy a widescreen external monitor to use with the HDMI port. The monitor I want to buy is Lenovo L29w-30 / 29" 90Hz 4 ms FreeSync IPS FHD widescreen 66E5GAC3TK 2560 x 1080
How can I find out if my graphic card supports 2560 x 1080 resolution from the HDMI port?

Lenovo ThinkPad E14 Gen 4 User Guide (appendix, page 15):

4K @ 60 Hz HDMI = 600 MHz TMDS = 18 Gbps

Lenovo L29W-30, 29" monitor:

• 2560 × 1080 @ 90 Hz RGB 8-bit (6b+2b FRC) CVT-RB = 8.2 Gbps
• 1 x HDMI 1.4
• 1 x DisplayPort 1.2
• VESA AdaptiveSync, AMD FreeSync

The bandwidth should be sufficient for HDMI, but honestly speaking, there are frequently problems on HDMI with ultra-wide monitors (in this case WFHD, 64:27), so I would recommend connecting the monitor via DisplayPort. This also has the advantage that you can use the AdaptiveSync function of the monitor, which is not possible via HDMI 2.0.

In your case, it is unfortunate that the laptop's power supply and the DisplayPort signal path are on the same connector:

But you can use the low priced Lenovo USB-C Dual Display Travel Dock with power adapter and then connect it like this:

If you don't live in the US, you'll need to order it in your country. Different power standards!

You may have to purchase the DisplayPort cable separately.

If the DisplayPort version is too expensive or complicated for you, I would get a written assurance from Lenovo Support in advance that this laptop will work with this monitor via HDMI with the native ultra-wide resolution.

Thank you for your quick response and the information you provided. I did not receive a response from Lenovo.
In this case, it would be better to buy a monitor that can both display and charge my computer via Type-C. Because the travel dock may not be very useful for me. I have another question, is there a list where I can see all the resolutions supported by the Intel Iris Xe graphics card? It would be a bad surprise to see black areas around the edges of the monitor I will purchase when I connect it to the computer.

For example, if I buy this monitor, will I have a bad surprise? I wonder. https://www.lenovo.com/tr/tr/monitors/p34w-20/ Thank you again for your information and support.

With Thunderbolt 4 you shouldn't experience any surprises. It can do anything. It provides the DisplayPort 1.4a HBR3 protocol (with DSC if needed), which you could even use to run the largest monitor available: Samsung Odyssey Neo G9 G95NC > 7680 x 2160 @ 120 Hz.

The suggested ThinkVision P34w-20 does not support proper USB-C Power Delivery (PD) to power your laptop. That would of course be the most elegant solution. Everything via one cable. If you don't care about the make of the monitor, the most affordable monitor on the market is the Philips 6000 Series 34B2U6603CH (34").

• Thunderbolt 4
• PD with 100 watts
• 3440 x 1440 @ 120 Hz
• approximately € 650

In such a case, please use a certified Thunderbolt 4 cable, e.g. this one: Cable Matters Thunderbolt 4 cable

I checked the features of the ThinkVision P34w-20 monitor from the Lenovo website and bought it.
I started using only the Type-C cable for charging, display and wired Ethernet. The resolution is exactly as I wanted. For now, everything looks great. Thank you again for the information you provided.

The monitor i bought: ThinkVision P34w-20

Great! I'm very happy that you now have a monitor that works as hoped.

Out of interest, I would like to know how long the Lenovo monitor's USB-C Power Delivery takes to fully charge your laptop?
