Using Apple USB-C to HDMI adapter and HDMI cable both which work as I've connected the MacBook Pro to Vizio TV with no problem. The only thing I can think of is the technology in the HP 2311 can not support the MacBook Pro.
MacBook Pro 13″, macOS 11.4
Hello Grant and thank you for the quick response to my question. This monitor has all three connections (see below). The cable is marked "All Systems Broadband, 2390 High Speed HDMI cable with Ethernet E119932, AWM 20276 VW-1 80° C 30 V Copartner.
Here are the specs for the Vizio TV (https://www.vizio.com/en/tv/d-series/D40f-G9). I can adjust the 2311 resolution from 800 X 600 and higher.
Again, thank you.
HP LV2311 is a 1920 by 1080 display has two inputs:
(1) VGA (analog),
(2) DVI-D w/HDCP
¿How can you be connecting with HDMI? are you using an additional adapter HDMI <-> DVI ??
HP 2311x has three inputs:
HDMI, DVI-D & VGA connectivity
¿which is yours?

Recent Macs can detect data errors on their cables, so the types of cables required must be higher standard:
HDMI cables you want for HDMI-only Monitors (higher resolutions than 720p TV sets) are marked as Certified with an anti-counterfeiting tag and are labeled:
"Premium High Speed HDMI cable" or that + "with Ethernet" --OR--
"Ultra High Speed HDMI cable" or that + "48G"
Cables with No Certification tags are good for your standard 720p TV set, and not much more.
I suggest you try HDMI cable marked "Premium High Speed" and with anti-counterfeiting tags.
Also, keep in mind:
to get a Mac display to become active, you need the Mac to query the display, and the display to answer with its name and capabilities. Otherwise, the display will not be shown as present, and no data will be sent to the display. "No signal detected" is generated by the DISPLAY, not by the Mac.
This query is only sent at certain times:
• at startup
• at wake from sleep — so momentarily sleeping and waking your Mac may work
• at insertion of the Mac-end of the display-cable, provided everything on that cable is ready-to-go
• on invoking Option-(Detect Display) button in Displays preferences (from another display)
so try doing some of those things and see if the display comes alive.
Modern Displays with multiple ports are sometimes busy scanning the other ports, looking for an input, and miss the query from the Mac. They need to pay attention to the port you are actually using, or they will miss the query.
Some displays have On-Screen Display settings that can be used to tell the display a computer is attached on a certain port, or a certain port should be highest priority. Changing those may make your display more responsive.
Some displays include their own private "sleep" settings for the display alone. This can allow the display to enter its own sleep mode, on top of the Mac's not sending it data. A display that is sleeping on its own cannot respond to the Mac's query, and will stay dark.
Thank you. I will have to go shopping for a new cable. You can mark this closed and if I need more assistance I will post a new question. Thank you again, take care and have a great week.
