Hi Kevin, We give a test with OpenChrome UMS 0.4.0 driver on T510/T5555/C90LE/V90LE thin clients for DVI-I and DVI-D ports(C90LE and V90LE do not have DVI-D port) and get following results: DVI-I DVI-D T510 fail suc T5555 fail suc C90LE fail X V90LE suc X From the result we tested, it shows for DVI-D port for T510/T5555, the UMS driver is working fine; By contrast, for T510/T5555 DVI-I port, the UMS driver is failed to work. The possible reason is that DVI-I uses a external TMDS transmitter Silicon Image Sil164 which current UMS driver does not support. For V90LE and C90LE, the result is very interesting because they both uses VT1632 as the external TMDS transmitter, but the result is totally different. Thanks, Frank</pre> </div> <hr> You are receiving this mail because: <ul> <li>You are the assignee for the bug.</li> </ul> </body> </html>
