Hey guys,
I'm not sure if this is the right place but I'm pretty desperately looking for help. If this is the wrong thread or if I should just open a new one, just delete or move this
Story first:
I've been assuming that the HDMI ports of my old Toshiba TV were defective. For about two years I couldn't manage to get a connection between my PC and my Toshiba via HDMI working. The weird thing is, it worked before and it worked for a long time (with a 5850 and with a 660). I was assuming I somehow broke the HDMI ports of the TV, dunno exactly how. That's why I sold the TV about a year ago.
Now I got myself a Sony KDL-40W705C. I thought with a new TV I wouldn't have any problems like that. Well, I have and I have no idea what the exact problem is.
Rig (WIN7 64bit):
- Phenom II X4 955, not oc
- 8 gig Ram
- 128GB SSD and 1 TB Samsung
- Gigabyte GTX 660oc 2GB
- on a ASUS M4A79T Deluxe, no onboard graphics etc (really old board)
Setups (that obviously didn't work): PC --> TV
- HDMI --> TV. No signal, all I get is a black screen. Neither the PC nor the TV does anything, no ba-dump sound, no hand-shake is happening, as if I never connected them. both the nvidia control panel and the windows display properties/monitor setting do not show a second display.
- DPtoHDMI adapter ---> HDMI ---> TV: exact same thing.
Now based on these problem I was assuming that I was maybe wrong all over thinking that it might be the HDMI and DP port of the PC/660 that are not working. So I tried connecting my PC monitor (LG 24GM77) via those ports.
Setups: PC --> PC monitor
- HDMI --> HDMI in of PC monitor: no signal, nothing.
- DPtoHDMI adapter --> HDMI --> HDMI in of PC monitor: works. Got a picture (see pics).
So, it seems that the HDMI port of my 660 is not working. That's a shame but as long as the DP works I still a have an option to connect a second display and I'm fine with that. Nevertheless, connecting the TV via the DPtoHDMI adapter and an HDMI cable does not work.
So after ruling out that all ports a broken, DP should really be the way to go. But as you can see in the pics, with the TV connected via DP I have zero options doing anything. It just doesn't get detected, no hand-shake (the Sony TV and my laptop work perfectly fine together btw, handshake took merely a second).
Things I'm looking into right now:
- My registry is a mess (pic). There are many entries for old, unused displays (Toshiba TV "TSB106", "sony" is me trying stupid things, old LG monitor). Can't manage cleaning that up, deleting the entries does not work (I took ownership). I think the only way to get this sorted out if this is the problem's solution is a fresh wipe and re-install of WIN7. Maybe someone can help me with this point.
- Custom resolutions. I think this could also cause these problems. Afaik, I cannot create a custom resolution for a display that is not even detected. At least I can't. Also CRU needs a display to create a new resolution for. I know I can't run the TV on 120/144hz so I'm running on 60hz and 1920x1080 atm.
- The funny thing is, when I connect my PC monitor via DPtoHDMI the nvidia control panel shows that it is using a Ultra-HD, HD, SD resultion with 59hz (pic). This is still not a HDTV resolution but I think that that's pretty close to what I am actually looking for.
- TV: Maybe there something I need to do with the TV. I have no clue about TV settings (are there advanced menues?). But I guess it's simply PnP.
I hope there is someone who can point me in the right direction. Thank you for reading
