These are older TV's, from the = 2000's, I guess the EDID might not be entirely compliant with modern standa= rds. A newish AEC monitor (not TV) did work with the latest kernels so not = all VGA connected monitors are affected. >From searching online it seems that there are numerous reports of monitors = stopping working with the 6.2 kernel in various distros. This is the commit where the problem apparently first appears: https://cgit.freedesktop.org/drm-intel/commit/?h=3Ddrm-intel-fixes&id=3Df53= 0bc60a30bee47ff51b7fb71511fdd058b774a commit f530bc60a30bee47ff51b7fb71511fdd058b774a (HEAD) Author: Ben Skeggs Date:=C2=A0=C2=A0 Wed Jun 1 20:46:33 2022 +1000 =C2=A0 =C2=A0 drm/nouveau/disp: move HDMI config into acquire + infoframe m= ethods =C2=A0 =C2=A0=20 =C2=A0 =C2=A0 v2: =C2=A0 =C2=A0 - fix typo in sorhdmi/g84 struct initialiser (kbuild test rob= ot) =C2=A0 =C2=A0 v3: =C2=A0 =C2=A0 - less convoluted flow control in nvkm_uoutp_mthd_acquire_tmd= s() (lyude) =C2=A0 =C2=A0 v4: =C2=A0 =C2=A0 - we don't support hdmi on original nv50, don't try =C2=A0 =C2=A0=20 =C2=A0 =C2=A0 Signed-off-by: Ben Skeggs =C2=A0 =C2=A0 Reviewed-by: Lyude Paul
