red pixels with high resolution - chpo7234 - 10-19-2015

hey guys i hope u can help me.

i bought a new Pi2 Model B.
I tried stable and beta-image für this model and many many config-stuf.... at last "hdmi_drive=1" helped me to get into the menu. hdmi_drive=2 doesnt work.. Without hdmi_drive=1 option the TV says "no signal / wrong format".

I do not have any problems while using 600x400-resolution, but if i increase it, i get a screen full of red pixels... take a look:

problem is still existing =/

i have tried everything..... every port, different cables, different sd-cards, different operation systems, different power cables (usually i use 5v 2,1A), different energy sockets, many config-options....


i found the following commands for openelec:
1. Run “tvservice –m CEA” to give a list of CEA supported modes.
Quote:Group CEA has 15 modes:
(native) mode 1: 640x480 @ 60Hz 4:3, clock:25MHz progressive
mode 2: 720x480 @ 60Hz 4:3, clock:27MHz progressive
mode 3: 720x480 @ 60Hz 16:9, clock:27MHz progressive
(prefer) mode 4: 1280x720 @ 60Hz 16:9, clock:74MHz progressive
mode 5: 1920x1080 @ 60Hz 16:9, clock:74MHz interlaced
(native) mode 16: 1920x1080 @ 60Hz 16:9, clock:148MHz progressive
mode 17: 720x576 @ 50Hz 4:3, clock:27MHz progressive
mode 18: 720x576 @ 50Hz 16:9, clock:27MHz progressive
mode 19: 1280x720 @ 50Hz 16:9, clock:74MHz progressive
mode 20: 1920x1080 @ 50Hz 16:9, clock:74MHz interlaced
mode 21: 720x576 @ 50Hz 4:3, clock:27MHz x2 interlaced
mode 31: 1920x1080 @ 50Hz 16:9, clock:148MHz progressive
mode 32: 1920x1080 @ 24Hz 16:9, clock:74MHz progressive
mode 33: 1920x1080 @ 25Hz 16:9, clock:74MHz progressive
mode 34: 1920x1080 @ 30Hz 16:9, clock:74MHz progressive
2. Run “tvservice –m DMT” to give a list of DMT supported modes.
Quote:Group DMT has 11 modes:
mode 4: 640x480 @ 60Hz 4:3, clock:25MHz progressive
mode 6: 640x480 @ 75Hz 4:3, clock:31MHz progressive
mode 9: 800x600 @ 60Hz 4:3, clock:40MHz progressive
mode 11: 800x600 @ 75Hz 4:3, clock:49MHz progressive
mode 16: 1024x768 @ 60Hz 4:3, clock:65MHz progressive
mode 17: 1024x768 @ 70Hz 4:3, clock:75MHz progressive
mode 18: 1024x768 @ 75Hz 4:3, clock:78MHz progressive
mode 23: 1280x768 @ 60Hz 15:9, clock:79MHz progressive
mode 35: 1280x1024 @ 60Hz 5:4, clock:108MHz progressive
mode 39: 1360x768 @ 60Hz 16:9, clock:85MHz progressive
mode 82: 1920x1080 @ 60Hz 16:9, clock:148MHz progressive

3. Alternatively you can do the following:
Run “tvservice –d <file>” to capture a monitor’s EDID.

sorry for spamming.. i can reduce the red pixel flood to a minimum while using 640x480... but usually i want to HD-TV-Stream lol.... Doesn't work, eh? =/

any tips/comments?

greetings

What if you select the video mode(s) directly via the SSH command line?
Does anything useful happen? Apparently your listings show that FullHD screens should be possible.
"(native) mode 16: 1920x1080 @ 60Hz 16:9, clock:148MHz progressive"

hey,

yes, i also tried many modes with putty:

mount -o remount,rw /flash
nano /flash/config.txt
inserting "hdmi_mode=16"
saving
mount -o remount,ro /flash
reboot

doesnt help. i think my TV is too old for PI. i ll send this Pi back to amazon... =/
