CrossOver 27Q LED/LED-P, 27M LED, & 2720MDP GOLD LED Monitor Club - Page 621

post #6201 of 6483
Hi all,

I'm in the market for a 1440P monitor and am looking at the Crossover 27Q. However, I also found they have these 27QW or 27QD for slightly cheaper, about $50 or so. When I look at their specs between the Q and the QW or QD, the only differences besides the case and stand is that the Q has S-IPS panel and the others have AH-IPS panel. I know that AH-IPS is newer tech so why is it cheaper than the older S-IPS? Any other differences I missed?

Thanks

So, if you only had 4 bit colour, and you wanted orange, which isn't in 8 bit colour, you could quickly alternate red and yellow dozens of times a second and it would mix to become orange. Yes, that is totally the wrong mixture of light to get orange I know. Just an example.

Same thing with 8bit +FRC. It can display 8bits of true choir intensity per channel 8 levels of intensity of red, blue or green) and can also simulate inbetween levels by switching between different levels of red/blue/green very quickly.

A true 10 bit panel actually has 10 different levels of intensity for each color channel. it could theoretically apply FRC on top of this for 12 bit colour. But that would be overkill.

The takeaway? Don't worry about 8bit±frc vs 10bit. It is unnoticeable except if you use a tool specifically intended to measure the difference.

You probably wouldn't notice a difference between 6bit+FRC vs true 8 bit to be honest. I know I have to look at specific test images that are meant to show off the differences in order to tell which is which.

Edit - oh, one more thing. 8bit panels don't show a more intense red than a 6bit panel. 100% red on a 8bit panel and 100%red on a 6bit panel are, all else being equal, the same shade of red. It just happens that the 8bit can show 256 different levels of red while the 6bit can only subdivide it's red levels into 64 steps.

Great response, thanks. +REP

The anime community are big into their 10bit releases but I haven't really seen it anywhere else. I ended up going for a Qnix but I might end up going for one of these 8bit+FRC displays in the near future thumb.gif

o.O Anime reencodes are one of the worst places for 10-bit colour. >.> Wow.

Very well?

Their source material isn't 10-bit, so it's not as if a 10-bit encode will make a difference. It would be like the fansubbers encoding 4K video from 1080p source material. Anime's not exactly rich in colour detail either, which is what 8 bit vs 10 bit colour allows you to delineate.

Or does your description of 8/10bit selectable 120hz panel mean a panel capable of 8 bit colour, with the option to strap on FRC?

8/10bit selectable 120hz panel meaning a video board capable of 8 bit colour, with the option to strap on FRC. I don't know the exact LG model number of the panel so I am just assuming thats what ehy are doing to achieve 10 bit @ 120Hz. You could use a 8 bit 60Hz video board and a 24 bit lvds cable that would make the panel 24 true. You can use a 8 bit 60Hz video board + FRC to upscale it to 10 bit 120Hz. The correct and more expensive way would be to use a dedicated video board supporting 10 bit 120Hz using a 30 bit lvds cable.You can't feed a 8 bit non selectable panel 10 bits of data and expect it to work. You'll have more data pins/wires on the lvds coming out than what there is on the panels input lvds logic board.

older technologies get higher in price because of less demand and newer technologys are cheaper because of more demand? desktop memory for example. I would buy a AH-ips panel since they are whats current. My choice would be the blacktune model 2755 or 2763 since they are 10 bit 120Hz monitors.

Wait, has it been proven that the 120hz wasn't frame skipping at all? Also, what difference does 10 bit make? I have not seen this in action and I hope to see a night and day difference with it, especially when coloring in photoshop.


Have the QC of the blacktune improved? They said that the blue spots that were on the lcd screen were annoying, and I was squeemish to get that monitor, so I opted for the 27qw, which has got to be one of the most accurate colored displays I have ever seen. I still couldn't review them together, sorry fellas, but I can say this.

The crossover27q and the qnix qx2710 without calibration (as well as the 27qw), cannot beat the 27qw in stock calibration settings, they all have similar color details, but I feel that the 27qw, while cooler, tends to be the most accurate and a bit less saturated as well. The white also look EXTREMELY white, no red or yellow tints unlike the other two.

They don't display 120 fps... They are most definitely frameskipping monitors.

If they are selling a frame skipping monitor that is horrible. Why would they market it as 120Hz when people are expecting the higher refresh rate? 10 bit there are more colors displayed in each level of color in the panel. 8 bit 16.7M and 10 bit 1.07B colors. Sounds like you were very happy with your purchase of the 27qw. I currently have the 27Q when crossover first started production. Its pretty close to the same monitor, AH-IPS Vs S-IPS, slimmer, looks like a newer revision of the 27q. I'm in the market for a 120Hz AH-IPS (10 bit preferred) monitor.

Sad, but that would all come down to your gpu right? Has anyone ever tested the monitor with say a titan or 660Ti SLI on up? Also vsync should help in game if its skipping frames right? Thats dumb they market the monitor to run at 120Hz.
