Arc A750 HDMI output compatibility with Dell monitors

ZephyrWuTWN — Sun, 22 Jun 2025 04:38:00 GMT

Hi,

In past year I used Arc A750 with an Acer 2K monitor connected by HDMI output ,it works perfectly wiout any problem .
Last week I bought a new Dell 4K monitor P2725QE ,but had compatibility problem when connected with HDMI output .

When connected new monitor by HDMI ,BIOS post screen displayed then "No HDMI signal" message shown on monitoe when Windows login procedure .
After swithced to DP output ,Windows screen showed no problem .

I used another portable monitor to test ,Windows shows second monitor but can't recongnize resolution when connected by HDMI .
In this condition P2725QE didn't show any picture no matter what kind of multi monitor display was selected ,only portable monitor display normally .
I changed old Acer 2K and another old FHD monitor connected to A750 HDMI ,and RTX 3050 HDMI output to P2725QE ,all of them worked without any problem .

Here is my test summary this week :
A750(DP) -> P2725QE : OK
A750(HDMI) -> P2725QE : NG(in Windows)
A750(DP) -> Other monitor : OK
A750(HDMI) -> Other monitor : OK
RTX3050(DP) -> P2725QE : OK
RTX3050(HDMI) -> P2725QE : OK
CPU built in UHD 770(DP) -> P2725QE : OK
CPU built in UHD 770(HDMI) -> P2725QE : OK

Currently system is running Windows 11 24H2 ,Intel Graphics driver 32.0.101.6881 .
I'm not sure if this is an issue of monitor or display ,I will also report to Dell support .
