Hi all! Figured since there aren't many avenues out there as of yet that properly show how to dissect your phoenix, I'd try to take up the mantle with my own experience in upgrading the LCD panel from FHD 1080 to the 4K panel. Before we get started, I'd like to present a list a useful tools to have beforehand if you intend to pursue this endeavor. I'll be providing pictures of my own tools as well as links to various components you need for purchase if you intend to follow-suit: MOD EDIT: ATTENTION HUGE PICTURE LOAD AHEAD!
Hello earth, WARNING: although this is a semi-guide, what you're about to read isn't for the faint hearted XD, I'm not responsible for any damage, fire, death to your pet etcetera if you attempt to do it... As you may already know, you cannot force custom timings on intel igps, unlike dGPU system only, since Intel IGP cannot do EDID overrides. More about EDID: https://en.wikipedia.org/wiki/Extended_Display_Identification_Data The solution was to dump the EDID which can be done using modeline in windows registry, linux modeline, or dumping directly from the EEPROM (electrically erasable read only memory found physically in most screen logic) which should be straightforward as we need to actually reflash it with our modification simply over i2c interface using arduino (simple 328 with serial-to-usb, can be from 8$ to 25$ max) you can also buy an EEPROM programmer which can be slightly expensive. The screen I have is a CMN1B, Chi . Should also work with AOU 95% gamut screen, any screen with i2c interface to eeprom, you can actually trace it along the 18th and 19th pin from the LVDS cable, however it should be pretty visible. So I ended up (easily), disassembling the screen as per this guide: [GUIDE] How to replace an LCD panel on a Clevo shell (pictures included) | NotebookReview I've then cut the film from both sides then taped for making it easier to work (i.e: instead of cutting EEPROM's pin location): There are 2 EEPROMS in my case, identified it simply by looking at the test point tagging, EE_SC SD etc, should be similar in any other displays: Tip size reference, basically any 15 to 30 watts soldering iron should work, unless the testpoints are tiny on other displays like AUO, though it is least likely you will ever have to desolder the EEPROM chip: Sold'er! Roger that(You can see the EE_* tags, SC for clock, and D for data etc): Connect to my Duino(wire it as you normal i2c): My EDID dumped in Linux before proceding to flash: EDID: 00ffffffffffff000daeb11500000000 01160104902213780231d59f56589527 15505400000001010101010101010101 010101010101963b803271383e405a3c 690058c21000001a9b2580ee70382340 3523350058c21000001a000000fe0056 434d3858024e31353648470a00000000 000041319e0000000002010a20200005 BACKLIGHT: 133 range: (0, 976) Backlight: 133 range: (0, 976) scaling mode: Full aspect supported: None, Full, Center, Full aspect Broadcast RGB: Automatic supported: Automatic, Full, Limited 16:235 audio: auto supported: force-dvi, off, auto, on 1920x1080 (0x4c) 152.5MHz +HSync -VSync *current +preferred h: width 1920 start 2010 end 2070 total 2226 skew 0 clock 68.5KHz v: height 1080 start 1086 end 1095 total 1142 clock 60.0Hz Pasted in Deltacast EDID editor then modified Pixel clock from 152 mhz (60hz calculated in DTD calculator) to 209 mhz, you have to calculate by entering these from the upper code repecitevly from top to bottom 920x1080 (0x4c) 152.5MHz +HSync -VSync *current +preferred h: width 1920 start 2010 end 2070 total 2226 skew 0 clock 68.5KHz v: height 1080 start 1086 end 1095 total 1142 Export the modifications in EDID editor as hex, make sure you add 60hz(original mod) in block 3 so you can switch between 40 60 120, then using find&replace method modify the format according to the next step Then modify the array in the code (acc to format, 0x and ,) upload to arduino: https://learn.adafruit.com/adafruit-tfp401-hdmi-slash-dvi-decoder-to-40-pin-ttl-display/editing-the-edid I'v managed to go up to 120hz stable, yours may be different although the same model number... xrandr output at 85hz: Had to reboot twice on Windows under UEFI boot manager in order to recognize the 120hz option, weird Again, this is not a thorough guide, just sharing my experience. It went pretty straightforward, and simple as a typical EDID modding over VGA cable or DVI.
Hi, Long time member and even longer a lurker. I've modded and OC'ed various GPU's using the vbios' shared in the forums, however I'm having problem with the 970M 3gb, which I've gathered recently from ebay. I hope it hasn't been asked a zillion times. I bought a 970M 3gb model which goes by the model name MS-1W0J1, and been trying to get it working on an Alienware M18x r2. I've successfully installed the card and it seemed to work plug and play. The card is recognised by BIOS and I get video output in startup menus, both in EFI and LEGACY modes(I'm using Swick's latest bios for this model). However, there seems to be a problem when installing the Geforce drivers(both 380&390) in Windows 10, as the screen goes black instantly when the driver has been updated. I can't get any video output in Windows, and the only option is to switch to integrated card and remove the drivers. I've seen different mods and modded vbios' for 970M cards, but none seems to be for the 3gb model. I wonder if there is a way to set-up this card on this hardware and flash a compatible CLEVO vbios to get it running without issues. Current vBIOS is attached. Thanks in advance, Wejgomi GM204.rom
There are many places that talk about the idea of using the 2013 Alienware 18 screen panel or screen assembly on the previous m18x r1 & r2. What I would like to find out, definitively, is could this panel be transplanted into the older generation which honestly isn't the best quality. Alienware 18 has a PLS based screen made by Samsung, which will have all around a better picture as compared to most TN based panels (especially the one found in the m18x). What needs to be discovered: - Alienware 18 screen connector (after this has been answered we can continue to the next set of questions) Is it LVDS 40 pin? Something else? Next up: - Alienware 18 screen assembly dimensions and construction Is it possible to just use the entire 18 screen assembly? **PICTURES! **MEASUREMENTS! This should just about cover what we would need to then allow me, or someone else, to proceed with actual testing. Everyone's help would greatly be appreciated!
