That just means it can output 120 Hz using frame interpolation. The review doesn't mention if it can handle 120 Hz input.

This sounds like a possible EDID problem or a driver bug. Use the power cycle trick to get it working. Then use MonInfo to save the real-time EDID to a .bin file and post it here so I can see if there's anything wrong with it: http://www.entechtaiwan.com/util/moninfo.shtm

thank you so much, its strange in this page some one ask this Is this a true 120hz panel TV? Not a 60hz, right? and the answer is Yes, it is a real 120Hz TV.

Looks like you also asked here: http://www.rtings.com/tv/reviews/samsung/h6203/settings

He gave the same answer:

Quote:There are no Samsung TVs that accept a 120hz input at the moment. They are only able to display 120Hz internally via interpolating a 60hz or lower signal. You can see the full list of TVs that support a real 120Hz input here.

Quote:Screenshots represent the pixel data, not the (card) output.
What do you mean?

I mean screenshots are basically RGB 4:4:4 because the pixel data is always RGB. The conversion to YCbCr happens on output.

(12-26-2015 11:39 PM)zamar19 Wrote: [ -> ]Also, how a GPU driver can determine monitor color depth choice supported at given resolution, if color bit depth is stated "undefined" in EDID?

If the color depth is undefined, it's normally assumed to be 8 bpc. This only applies to EDID 1.4. EDID 1.3 does not have color depth information in the base block.

(12-26-2015 11:39 PM)zamar19 Wrote: [ -> ]Indeed, with the option ticked "Import complete EDID", CRU imports bin and exports inf without conversion. But when the exported EDID v1.4 is written to Registry by successfully installing via Device Manager with Sig Control off, upon reboot the newly installed override when exported from Registry shows EDID v1.3 and no YCbCr 4:4:4 in base section in Notepad++. I deleted all other hidden monitors, so no other display profiles are shown in Registry.

If I save the imported bin in CRU by pressing OK (its presumably saved in Registry), and then restart the driver by running restart64.exe, Windows creates a new Generic Monitor profile without Override keys in Reg, but upon reboot the old profile with updated by CRU override section is used instead, and its again EDID v1.3 instead of v1.4.

That's strange. Windows would not convert the EDID override, and neither would the driver. This sounds more like the EDID override is reverting to the previous configuration. Maybe there's something wrong with it. Can you post the .inf file so I can take a look at it?

(12-26-2015 11:39 PM)zamar19 Wrote: [ -> ]I tried the test image at 1080P resolution with Just Scan option turned On in the TV Setup GUI. With that option, a 1080P reso desktop is shown centered at native 4K TV reso, but occupies only 1/4th of the entire TV screen as it should (of 4k or 4k UHD native screen?) without scaling to fit. The test image at 100% zoom shows both values equally clear 4:2:2 and 4:4:4 as on this photo, which was scaled down for upload in an image viewer, but shows exactly what I see on screen regardless of RGB or YCbCr 4:4:4 output selected. How to interpret it? Can it mean that at 1080P native reso, the LCD controller converts any incoming signals to 4:2:0, and the test image is confused? In 4K reso it only shows 4:2:2, and on another 1080P monitor only 4:4:4, but not both values at once.

That's weird. The TV is messing with the image somehow. Try playing with the sharpness setting if it has one.

(12-26-2015 11:39 PM)zamar19 Wrote: [ -> ]How likely Seiki to enable 4:4:4 in firmware owing to customers outcry? Is it competition driven of 4K TVs versus 4K monitors? I think so, since any HDMI2.0 rev B or A port must support 4K@60Hz 8bpc 4:4:4 signal as per HDMI2.0 standard.

I have no idea, but maybe they'll do something if enough people complain.

(12-26-2015 11:39 PM)zamar19 Wrote: [ -> ]On a relevant note... Can you suggest any tool or method that would ID the DP version (1.1 or 1.2) and profile (HBR or HBR2) used in my V4900 card, or measure max DP throughput? Can I flash GPU BIOS to upgrade the DP profile? AMD site says its v1.2, but Dell spec says its DP (no version given, but V1.1 means twice lower bandwidth limit). The card 800 MHz engine clock seems to allow driving at least one 4K@60Hz 8bpc 4:4:4 display.

I don't know of a way to check the DisplayPort version or the bandwidth limits.

You should be able to enable Eyefinity after configuring the monitors separately. If it still only allows 60 Hz, try making 75 Hz the first detailed resolution for all three monitors.

Quote:EDID override is reverting to the previous configuration. Can you post the .inf file so I can take a look at it?

See attached INF. But it looks in previous EDID 1.4 bin I ticked Dual DVI support, and since this TV doesn't have a DVI port, may be it caused the reversals?

Quote:This TV may not support 4:4:4 at 30Hz or at all.

Contrary to its own EDID? In this review of the winning Samsung: "by using PC mode and enabling ‘UHD color,’ it can display a 4k @ 60 hz @ chroma 4:4:4 signal". I wonder if I'm missing some switch in Service Menu in addition to PC Mode? Can you suggest anything looking through the TV's On-Screen Menus?

Here's the test image photo from this monitor. And other reported, its getting much worse at 60Hz. What these photos say to you? Can it be due to extra processing that's not switched off fully at PC Mode? How PC Mode in 4K TVs is different from Game Mode, since some offer both? Can it be that 4K TVs in Game Mode downgrade incoming signal to 4:2:0, thus freeing extra controller power to decrease lag? The TV Setup GUI offers PC Mode, but in Service Menu ist shown as Game Mode, so I wonder if Seiki just mixed up the modes in FW?

Also, when an HDMI port is selected in TV Source GUI, it shows 2160P. I wonder if it IDs the PC as TV source at 30Hz, and switches to chroma downsampling? The Service Menu calls HDMI sources "DTV", and VGA source "PC". When I select RGB 4:2:2 out in FirePro CC, the TV converts it to 4:2:0. It seems to just downsample any HDMI source signal one step, not only 4:4:4. May be its a FW bug preventing it to correctly ID source type and switch to proper display mode, not a hidden switch ticked for marketing reasons?

I tried using EDID 1.4 override, it works now with Dual DVI option unticked, but with v1.4 only one monitor is lit despite both are On and recognized, and no chroma improvements, so I switched back to v1.3. Earlier mentioned test image with both 4:2:2 and 4:4:4 shown indeed started showing just 4:2:2 when decreasing Sharpness to 0.

If you mean in the HDMI support data block, the driver doesn't use that information with EDID 1.3, but I never checked with EDID 1.4. You should probably set the digital interface type to "HDMI-a" in the base EDID.

That just means it will accept YCbCr 4:4:4, but there's no guarantee it will display properly.

I can't comment on the settings or how it behaves with PC/Game mode because I don't have the TV, but based on what you and other people have reported, I don't think there's anything you can do to make it display 4:4:4. This is something Seiki needs to fix.

The 60 Hz photo is probably 4:2:0. You need HDMI 2.0 to get 4:4:4 or 4:2:2 at 60 Hz.
