Any solution for 120hz TVs with no DP, DVI nor HDMI 2.0?

[Lawfer]

Say you have an HDMI 1.3 Full HD TV that supports up to 120Hz, how would one possibly go ahead and play PC games in 1080p 120Hz knowing that only HDMI 2.0 support 1080p 120hz and of course a TV wouldn't have DVI nor Display Port inputs?

Would using a Display Port to HDMI cable allow for 1080p 120hz, or that wouldn't change anything?

Most 120Hz televisions only accept 60Hz inputs. You can see if overclocking will get you there: https://www.blurbusters.com/overclock/120hz-pc-to-tv/

Thanks you, but in this case it is an actual 120Hz TV, so it's not about overclocking it, it's about trying to find a connection that would allow for 1080p 120Hz, I know that HDMI 1.3 can do 720p 120Hz, but since this TV is a Full HDTV I would prefer to get 1080p 120Hz, the problem is how since before the arrival of HDMI 2.0 only Display Port and DVI could allow for such a resolution with such a refresh rate.

It's not the TV that gets overclocked, it's the refresh rate on the connection. As I said, most 120Hz televisions do not support 120Hz input. The article that I linked gives you instructions on how to do it.

It's not a 3D HDTV though. It's a Motionflow 120Hz TV.

... and? 120Hz TVs were introduced so that 24/30/60 Hz signals could all be displayed without frame judder, long before 3D TVs were a thing. 120Hz input was never supported because nothing used it.

That's just the name given to Sony's frame interpolation, and has no relation at all to an actual 120Hz refresh rate.

I dare say that you'll not be going beyond 60Hz without overclocking (if that is even possible with your specific display).

We're just saying that even if the LCD panel is 120hz, the TV might not be able to process external 120hz input.

Some models that do 120Hz internally (e.g. Motionflow, 3D) can also accept 120Hz externally.

"Some" models simply means most won't (first answer to OP).
That page you linked gives all information if you still want to check your TV, and also adresses you primary concern: "Yes, 120Hz sometimes works on older HDMI 1.3 ports".
Please note the page also states "There is a much higher success rate with 1280×720 at 120Hz". That makes a lot of "maybes", but you might be lucky and get 1080p@120Hz. Who knows

I don't think a Display Port to HDMI cable would help, the issue is more likely to be on the TV side than on the PC / GPU side.

"Yes, 120Hz sometimes works on older HDMI 1.3 ports".

Really? Pretty much everywhere online the answers I seen were "no", but one person on hardforum mentioned that theoretically it should be possible because HDMI 1.3 and 1.4 do have enough bandwidth for 1080p/120, see:

What I have put in quotes is from the Blurbusters' page that was linked in the first answer to the OP, and that you also linked just 3 posts ago, maybe you could read it

Yes I know, but from what I am reading is that officially it is not possible on 1.3/1.4, it probably need some kind of "flag", "greenlight" or "handshake" to be enabled and that wasn't introduced until HDMI 2.0, because technically HDMI 1.3 should provide enough bandwidth to do 1080p 120hz, but based on what people say online it does not seem that it works unless you use some workarounds, such as the methods that were presented in the link from the second post.

I found more info:

The catch is that 1080p 120Hz is not officially listed in the HDMI Specification, so monitors will not report it as a supported mode to the OS, and thus the option for 120Hz will not appear in Windows when connected over HDMI.

Here too:

http://www.avsforum.com/forum/40-oled-t ... -hdmi.html

Basically seems like it's not possible because HDMI 120hz has never been officially supported until HDMI 2.0, someone even mentioned that technically HDMI 2.0 has enough bandwidth to do 1080p 240Mhz, but as it was with the 1080p 120Hz situation over HDMI 1.3/1.4, it can't be done (or rather "won't be done") because there is no official support for it.

What bottlenecking!

The TV in question has a VGA input though, I wonder if it would let me do 120hz in 1080p or 720p through VGA?
