The output from my computer to TV has a flicker / flashing effect. My computer has only Displayport, not HDMI(!) so I use the Displayport-to-HDMI adapter below.
The problem is: once every 10 to 60 seconds or so there is a quick flash for a tiny fraction of a second. The 'flash' seems to be some black and white rectangle pattern, i.e. the picture isn't going to a complete 100% black screen (or white), and it's not like the image is stuttering (like on Skype when you have a bad connection). It's hard to tell because it's extremely quick. The 'pattern' is different every time. The interval between flashes is irregular. Sometimes you might even go a few minutes without any; other times it's about 10 seconds apart.
Could a bad adapter do this? The problem only started recently, after everything running fine for a couple years. This is my second adapter (different brand); the thing is, I can't remember if it started exactly when I got the adapter, which obviously would indicate that's the problem. I think the second adapter was also working fine for a couple months and *then* the problem started.

Is that is a passive adapter or an active adapter? Active adapters are more expensive but are supposed to be more reliable and don't require Displayport++.

I had this problem.
Only stopped this problem when I used a DP to DP on my monitor.
It seems to be a problem with the refresh rate on HDMI mode.
My tiny is M93p.

I guess passive because it was cheap. The active one isn't even $10 more so maybe I'll try it if nothing else works.

[QUOTE=planetrock;2394934]
My problem has solved only connecting my Lenovo thinkcentre m93p using DP to Display Port on my Monitor input. The flicker and flash is gone.
Possible problem is HDTV resolution + Refresh rates with video changes (example: play a 720p@24 video on 1080p@60 display. Sometimes its switch to fullscreen and the problem show).

Accel is often recommended.
