NVIDIA GeForce GTX 660 (Gigabyte) Windforce. HDR support?

[Oldschool297]

I have a NVIDIA GeForce GTX 660 (Gigabyte) Windforce to this screen. I guess it do not support HDR? or DRM Even if the functions can be turned on in the screen.

I bought a AOC Gaming G2 CU34G2XP/BK WLED in Sweden as i live there for 4489sek/428.62$. In US it is much cheaper but the shipping costs is around 200$. It is the deluxe model to CU34G2XE/BK. It has PiP. 2 DP 1.4 ports, 2 HDMI 2.0 ports, a 3.5mm audio output, 4 USB ports and AC power input (internal power converter). 4489.44kr. Basic HDR10 support is provided at the VESA DispalyHDR 400 level. So not very bright by HDR standards and no local dimming required – plus a restrictive colour gamut by HDR standards. But enough to give a different look to things with 10-bit colour processing put to use. A 1ms grey to grey response time is specified alongside 1ms MPRT using the MBR strobe backlight setting, approach with caution as usual. ‘Low Input Lag’ is also noted. The stand provides tilt, swivel and height adjustment and can removed using a quick-release catch to reveal provision for 100 x 100mm VESA mounting. The ports face downwards and include; 2 DP 1.4 ports, 2 HDMI 2.0 ports, a 3.5mm audio output, 4 USB ports and AC power input (internal power converter).

I read. All NVIDIA GPUs from the 900 and 1000 series support HDR display output. The presence of HDMI 2.0 provides the bandwidth necessary for the higher quality signal desirable for HDR. The 1000 series adds support for HDR over future Display Port revisions.

The GTX 660 only has a HDMI 1.4A
It might be possible (I don't know) over a Display Port cable.

Not possible, and not really a matter of HDMI version - it's the Kepler GPU itself that does not support HDR. This limitation applies even to the Titans and the GTX 690. Fortunately for you, just about anything would be a massive upgrade - buy a RTX 4060 as a replacement, or if on a very low budget, the RX 6600 will do the trick.

Anyhow... that display is one of the "fake HDR" ones and you're better off using it in SDR. Upgrade your GPU asap though, the 660 is an obsolete and unsupported midrange model that is over 12 years old by now. It's just not a good card to have anymore, even if you don't play much in the way of video games.

Thanks. Is it much quality loss between 1.4 and 2.0? Yes i will find another card. Sad it was a fake HDR screen. It is misleading marked selling. What means by fake HDR? Does it not support it at all. By the nits on 300 it is to little. When it takes 400.

There is no quality loss whatsoever. HDMI 1.4 has lower bandwidth than 2.0 or 2.1, which limits the maximum resolution and refresh rate. For a 1080p display, HDMI 1.4 is more than enough, until you're talking higher than 165 Hz refresh rates. For higher resolution monitors you will lose refresh rate, your monitor seems to be 3440x1440 @ 180 Hz and has a VA panel. It's a pretty decent monitor, but it is well beyond your GTX 660's capabilities to drive it to its full potential. To get playable frame rates that are near your monitor's full potential on modern-day games, you will want at least an RTX 4070 SUPER.

By "fake HDR" I mean that it's just not good enough for it to truly take advantage of HDR, for that you will want an OLED monitor or TV, and even the more basic models cost between twice and thrice the cost of your monitor. Don't worry about it. That doesn't mean it's bad, it's just a traditional monitor that won't have self-emissive capabilities or at the very least, localized dimming zones in generous quantities, which are really important for HDR. There's a reason the 42-inch LG C-series OLED is a favorite for PC gamers, it's one of the cheapest truly HDR capable displays out there.

I guess i need a graphic card from 3/1/2016 as Displayport 1.4 was released then. AOC Gaming G2 CU34G2XP/BK WLED is on 3440x1440 but i see 3840 * 2160. Can i run that when i see that in my computer?

Not advised. Also 4K on Kepler will result in 4:2:0 compression and the image quality will be reduced. I don't recommend it.

The minimum you should purchase is an RTX 2060, but for that monitor I recommend the aforementioned RTX 4070 SUPER or faster.

I will look into it. Since this screen have DisplayPort 1.4 i guess it is better then hdmi. But i heard you do not need more than 60-75hz since videos do not need more.

This is a 180 Hz gaming monitor, and that is the refresh rate it should be operated at. Using it at a lower refresh rate will result in a loss of smoothness. Videos are either 24, 30 or 60 fps usually. Rarely you'll see 50 and 120 fps videos, so you should run the monitor at the very least 120 Hz - ideally, at the 180 it was designed to run at.

If you do not play video games at all (I take it this is the case, since you are still using a GTX 660), then all you need is a cheap entry level card such as the RX 6600 or RTX 3050 - those will do the trick. They will support your monitor's native refresh and resolution. The 3050-6GB, while not a performance champion, does not need external power, so depending on the kind of PC you've got, it might be interesting. Note that by this I specifically mean the 3050-6GB and not the regular 8 GB 3050, those do need external power.

For gaming, targeting 3440x1440@180, don't look below RTX 4070 SUPER/RX 7800 XT. Even those cards are on the slow side for that resolution and refresh rate for 2024 AAA games.
