Question RTX A2000 + LG C2 = can 4K 120Hz?

[FryderykChopin]

Hi! Sorry if the question is answered in the sticky already but I couldn't find it there... Anyway I want to connect RTX A2000 (which only has DisplayPort 1.4a connectors) to LG C2 OLED TV (which only has HDMI 2.1 ports). Is there any adapter that would allow a 4K 120Hz output? If so, could you please recommend a specific one? btw. are there any potential issues with using the adapter such as missing features or worse image quality)? thx in advance!

/ninja edit: Found for example this adapter: https://www.amazon.com/Cable-Matters-101101-BLK-Computer-Adapter/dp/B08XFYHFCK - it specifically says "this is an active adapter that supports DP 1.4 to HDMI 2.1 and it is capable of 4K@120Hz" - is there any reason why it wouldn't work for the purposes mentioned above? Should I expect any issues with it?

Worth a shot.

The GPU certainly could output HDMI 2.1, same chip as an RTX 3060. But if you are just using this for display, then you could potentially downgrade to something like an RTX3050. Or are you going for the small form factor of the A2000?

Hi, thanks for a reply. Well I dig the incredible energy efficiency of A2000 (sort of counterweight to the power hungry LG C2 I guess) and I can get one for a good price. The problem is that its potential return would be problematic if it turned out that I can't squeeze out the 4k120fps out of it, so I'm trying to figure it out in advance

Maybe perhaps there is some MiniDP to HDMI 2.1 that would do the job instead? Open to any suggestions. Thanks a lot

Also thinking, does Intel's UHD 770 support 4k120Hz output? I mean for general stuff, like browsing web etc

Although I might be mistaken I think DP 1.4 can only do 8 bit color at 4k 120. You monitor support HDR10

This might matter for a non gaming application, games tend to have issue getting anywhere close to 120 at 4k even at 8 bit color.

Adapters are not likely to work.
The LG needs hdmi2.1 to be able to run at 120hz.
My old graphics card had dp but not hdmi2.1
I did a lot of research and tried a dp to hdmi adapter which utterly failed.
I upgraded to a 3000 series card which has worked perfectly.

I see, I guess I'm out of luck with this one. Thx all for answers

Adaptors exist that do work, with limitations. The big one is you aren't getting Gsync support. But you should be able to get an adaptor that allows you to send a signal that falls within DP1.4 limitations.
