Clevo 7280 awful LCD screen

For the regular user that use this machine only for games, this might not be of importance, but for professionals users that need an accurate color rendition, this screen is less than ideal, it is only a 262K color LCD, with a really strong blue cast that is almost impossible to calibrate even with the most expensive Xrite devices on the market.

This screen :

uses only 6 bits per component, which makes the reproduction of subtle gradients full of color banding and very strong dithering.

I'm really surprised that a machine this expensive uses such a cheap LCD monitor. A huge step back in quality from previous models I owned from Clevo.

When mentioned the low quality to the reseller, I was advised to use an external monitor, which I understand the reseller might not be responsible for this low quality element in the notebook, but the use an external monitor totally defeats the purpose of buying a notebook.

I hope more people notice this and an optional LCD with better quality, or at least truly full 16.8 M color becomes available.

If I known this, I would not purchased this machine. Which is awesome talking about power, but useless for my job as a photographer and designer.

I'm very surprised after read the specifications for many LCD screens for laptop, that most of those LCDs are in fact RGB 6 bits only..... but for some reason on my other two Clevos I have, I do not see the quality problems I see on the screen of this particular model. I'm wondering if I have a bad screen on my notebook.

Can anyone check going to this website and looking at the gradient if you see banding on it or a perfect gradient?

I see banding on my notebook, bit not on the other two I have.

Thanks

Well. I've being reading a bit, apparently all the screens using this technology are RGB 6 bits, but some, are RGB 6-bits + Hi-FRC data and can emulate 24 bits color. Apparently the HSD173PUW1 does not use those 2 extra bits for dithering, hence the color banding on subtle gradients....

It does not fit, this machine is 16:9, old ones are 16:10. They should have an option for better screen, I'm about to spend 2K on a monitor, I would not mind to spend more on a better screen.

Yes it does, in fact applies to 90% of the laptops out there using TN panels. That is the computer I have, the 32 bits color is a misleading information that most people don't know what really is, you have RGB which each one have 8 bits, so you have 24 bits of color, which is 16 million colors, 32 bits it is still RGB 8 bits per color, the extra 8 are not used.

Here is the exact explanation.

Apart from the 24-bit representation of Truecolor, there are 32-bit RGB representations, all of which still represent 16,777,216 colors. (These 32-bit representations should not be mistaken or confused with Deep Color schemes explained further below.)
In some graphic cards, the so-called 32 bit per pixel display graphic mode is identical in precision to the 24 bit per pixel mode; there are still only eight bits per component, and the eight extra bits are often not used at all. The reason for the existence of such 32 bit representation is the higher speed at which most modern 32-bit (and better) hardware can access data that is aligned to the 32-bit-long word addresses, compared to data not so aligned.

So, they are not telling lies, the screen is 32 bits because receive 32 bits, but internally it uses only 6 bits per component, which is about 262,000 colors, add to that the LED back light which is around 9300 Kelvin in temperature, and you have a monitor that is extremely bright but also extremely bluish, and almost impossible to calibrate to 6500K which is the standard color temperature of good TVs and Video and Photography...

Well, actually in this case the 32 bits is just the way those 24 bits are transmitted to the device. If you check, you can't actually divide 32 in 3... Will give you 10.66667 bits per color :-)

Now, with the graphics card on that notebook and a Dreamcolor HP monitor, you could get a great gamut since the monitor is in fact real 30 bits color internally. Seem Eizo monitors like the one I use on my Flame are 12 bits per color. But we are talking about $3K just for the monitor.

The laptop itself is fantastic, I'm super happy with it, I use it mainly to run Lightroom and PAmatchit and PFtrack which are GPU driven apps, and is lighting fast. It is just when I want to do a print job or serious color correction, I need to use another monitor
